TITLE: WALL PANELS AND OTHER COMPONENTS FOR CUSTOM ENCLOSURES FOR SHIPPING CONTAINERS, MOBILE UNITS AND OTHER DWELLINGS

CROSS-REFERENCE TO RELATED PATENT APPLICATION

[0001] This application claims the benefit of United States Provisional Patent Application No. 63/303,443 filed January 26, 2022; the entire contents of United States Provisional Patent Application No. 63/303,443 is hereby incorporated herein in its entirety.

FIELD

[002] Various embodiments are described herein that relates generally to at least one of improved wall panels, roof systems, ceiling systems and floor systems and combinations thereof for making custom enclosures that may be used for portable, permanent and semi-permanent structures including, but not limited to, shipping containers and various types of dwellings, medical units such as portable intensive care units (ICUs) and operating rooms (ORs), step down or isolation rooms, long-term care units, and other segregated isolation chambers, and systems thereof as well as non-medical uses.

BACKGROUND

[003] The following paragraphs are provided by way of background to the present disclosure. They are not, however, an admission that anything discussed therein is prior art or part of the knowledge of persons skilled in the art.

[004] Mobile structural units can be helpful in providing temporary structures during times of need. For example, when the mobile structural unit is a mobile medical unit such as, but not limited to, mobile intensive care units (ICUs) or operating rooms (ORs) such mobile structures can be useful for field medical operations, and for expanding the capacity of a permanent hospital location to enable health care workers to respond to unplanned increases in patient loads. [005] While there are configurations of mobile medical units, including some that are in the form of modified shipping/intermodal containers, various practical matters are not addressed in the prior art. For example, while these conventional mobile structures are promoted for being rapidly deployable, this appears to stem solely from the fact that they are mobile, and they may not be versatile for use in different situations.

[006] Furthermore, the prior art does not disclose any formats, techniques or materials useful for constructing internal walls in mobile medical units in a way that can preserve the usable interior volume. Particularly for mobile medical units being constructed to have a footprint similar to shipping/intermodal containers, the amount of interior volume that is usable for personnel, beds, air handling, medical equipment and utilities is already somewhat limited. Standard interior wall construction materials and techniques that are in common use for larger spaces reduce in greater proportion the usable interior volume in smaller spaces.

[00178] In accordance with the teachings herein, there are provided various configurations of mobile, semi-permanent and permanent units that may be constructed as custom enclosures as well as various techniques and materials usable for construction of these custom enclosures.

[00179] The following description and drawings set forth various example embodiments in which the mobile, semi-permanent and permanent units are medical units constructed based on custom enclosures. However, many aspects described and depicted herein are generally applicable in mobile, portable, permanent and semi-permanent structures being constructed for other applications, and/or being used for other applications. Furthermore, in at least one embodiment, custom enclosures can be made using the wall, roof, ceiling and/or floor systems described herein without the use of a shipping container. However, in at least one embodiment, such custom enclosures may be used to create a shipping container.

[00180] Examples of applications in mobile, portable, semi-permanent, permanent and custom enclosure structures, for which the teachings herein may be applied, include, but are not limited to, storage containers, educational structures including a classroom and/or portables, a school structure, military structures, command centres, correctional facilities, penitentiary structures, hospitals and medical clinic structures, patient rooms, nursing stations, Operating Room units (OR), Intensive Care units (ICUs), pharmacy structures, testing and vaccination centres, quarantine facilities, laboratory structures, cleanrooms, long-term care facilities, healthcare facilities, natural disaster safe shelters, a biocontainment room (in case of chemical or biological attack or outbreak), a safe room, indigenous community housing, vertical farming structures, housing, social housing, remote community structures, grow rooms such as, but not limited to, grow rooms for cannabis or algae, multi-story housing, cottages, restaurant structures, bar structures, retail structures or shops, mining structures and specialty enclosures, for instance. Any of the aforementioned structures may be modular in nature such that units of such structures can be custom-built using embodiments and techniques described herein and then be assembled together to create similar but larger structures. Furthermore, aspects described and depicted herein may also be generally applicable to fixed (i.e. , immobile) constructions or semi-fixed medical or nonmedical infrastructure constructions such as, but not limited to, fixed or semifixed infrastructure for hospitals and medical clinics, or other medical or nonmedical applications as outlined above. [00181] Referring now to FIGS. 1 and 2, shown therein is a front perspective view of a mobile unit 100 and a rear perspective view of the mobile unit 100, respectively. The mobile unit 100 is based on a shipping/intermodal container 102 having a length of about 40 feet, a width of about 8 feet, and a height of about 8 feet. Alternatives in length and width of the shipping container 102 may be used in other embodiments. The shipping container 102 may be fit with four windows for providing patients with a sense of the environment outside of the patient chamber housed within the mobile unit. Alternatives in window configuration (more or fewer windows, or differently sized windows) may be used in other embodiments. The mobile unit 100 may also include a maintenance door 104 and two patient room doors 200 and 202 leading to two patient rooms (not shown) within the mobile unit 100. In other embodiments, the mobile unit 100 may be part of a larger infrastructure with antechambers or hallways that lead to the two patient room doors 200 and 202.

[00182] Referring next to FIGS. 3 and 4, shown therein are side and perspective views of a mobile unit 300, that is built as a custom enclosure, according to at least one example embodiment described herein. It should be noted that the elements and construction principles that will be described for the mobile unit 300 can be used with semi-permanent and permanent structures including a custom-built enclosure for a variety of different applications, as explained previously, including for manufacturing a shipping container. There is shown a double-panelled left side wall 302, a doublepanelled right side wall 304, an interior ceiling panel 306, a roof panel 308, a floor system 310, and an end face of a longitudinal support beam 312. In FIGS. 3 and 4, the two end-walls for the structure are not shown.

[00183] In at least one embodiment, two or more interior wall panels 314 may be connected in a co-planar fashion to create an interior wall of increased (side- by-side) width. The two or more interior wall panels 314 are generally further releasably connected to portions of two or more exterior wall panels 316 in a horizontally offset fashion such that interior facing surfaces of the interior wall panels 314 and the exterior wall panels 316 are spaced apart and parallel to one another. The interior wall panels 314 may also be attached to a longitudinal floor support beam 313 which has an upper surface that is shaped like an angle iron and is releasably engaged by lower portions of the interior wall panels 314. Alternatively, another type of floor system and connecting members may be used, an example of which is provided in FIGS. 21A-21 E.

[00184] In at least one embodiment, there is a cavity (e.g., see cavity 905 in FIG. 9A) between the interior wall panels 314 and exterior wall panels 316, when they are releasably connected to one another, which may be referred to as a wall cavity. The wall cavity may be used for the installation of the communication cables, piping, electrical wires, insulation, as well as electrical components/devices including, but not limited to, sound measuring and pressure control devices, or any other functional components required for the mobile unit 300. This double-wall panel construction methodology may allow for a reduction in construction time, as the interior wall panels 314 may be constructed fully before any of the between-wall functional components are added. This may enable workers to continue to work within the mobile unit 300 on any other required components inside the mobile unit 300 while the between-wall functional components are added from the outside of the enclosure of the mobile unit 300 to the exterior facing surfaces of the interior wall panels 314 before the exterior wall panels 316 are installed. In such embodiments, there is further ease of construction as is described in further detail with respect to various examples shown in FIGS. 5-10.

[00185] In at least one embodiment, at least one of the exterior wall panels described herein may have a height such that the top surface of the exterior wall panels is adjacent to an underside of the roof system (e.g., an underside of the roof line) or adjacent to an object that is under the roof system.

[00186] In at least one embodiment, at least one of the interior wall panels described herein may have a height such that the top surface of the interior wall panels is adjacent to the underside of the ceiling panels 306 or adjacent to an object that is under the ceiling panels 306. [00187] Alternatively, in at least one embodiment, at least one of the interior wall panels described herein may have a height such that the top surface of the interior wall panels is full height and is adjacent to an underside of the roof system (e.g., an underside of the roof line) or adjacent to an object that is under the roof system. These embodiments may aid with sound attenuation.

[00188] Alternatively, in at least one embodiment, the interior wall panel may be a flat panel that is releasably engaged to an exterior panel and may have additional layers of material such as insulation for improving the fire rating of the structure. An example embodiment of such structural systems is shown in FIGS. 24H-24I. In embodiments, where the fire rating is not as important double-wall panel systems may be used as described herein.

[00189] In another aspect, there is provided at least one example embodiment where two or more roof panels 308 may be releasably connected to one another in a coplanar fashion. Such roof panels are further discussed in FIGS. 15A-15C and 16A, for example. However, other types of roof systems may also be used in the various custom embodiments described herein (e.g., see FIG. 24M).

[00190] In another aspect, in accordance with the teachings herein, there is provided at least one embodiment where there is a longitudinal support beam 312 that may be placed on top of a double-panel wall section comprising several outer and interior wall panels 314, 316. The longitudinal support beam 312 may comprise an inner supporting shelf, wherein interior ceiling panels 306 may be placed and/or secured. In addition, one or more roof panels 308 may be placed and/or secured on top of the longitudinal support beam 312. In such embodiments described herein, the longitudinal support beam 312 is shaped such that a space is provided above the inner ceiling panels 306 and below the roof panels 308. This space between the ceiling panels and the roof panels, which may be called a roof cavity, may be used to house various building elements such as any combination of electrical wires, cables, piping, insulation, ductwork, HVAC components, as well as electrical devices including, but not limited to, sound measuring and pressure control devices, or any other functional components required for the mobile unit 300. In a similar manner as with the double-paneled wall system, the ceiling panels 306 may first be attached to the longitudinal support beam 312, and workers may then continue to work within the mobile unit 300 while certain functional components are added from the outside on top of the ceiling panels 306. When the necessary components have been installed above the ceiling panels 306, the roof panels 308 of the mobile unit 300 may then be installed and attached to the longitudinal support beam 312. Alternatively, the space between at least one of the roof panels 308 and the underlying ceiling panels may house insulation in some cases. Further information on the roof system is provided in FIGS. 15A-18.

[00191] In various embodiments, the ceiling panels 306 can be traditional ceiling panels with acoustical backing or without acoustical backing for improved Sound Transmission CLASS (STC) rating. For example, the interior ceiling tiles that are used in structures like hospitals and schools may be used for the ceiling panels described herein. Alternatively, insulated aluminum panels may be used for the ceiling panels described herein.

[00192] In alternative example embodiments, the exterior wall surfaces, such as the exterior surface of the double-panelled right side wall 304, for example, or inner surfaces of exterior wall panels of the structure may have additional layers of material added thereto in order to provide the custom structure with fire-rated walls (e.g., see FIGS. 24H-24K). Alternatively, or in addition thereto, to improve the fire rating additional components can be added to double wall panel systems, multiwall panel systems (e.g., see FIG. 14G), or flat inner wall panel systems (e.g., see FIGS. 24H-24I I) such as one or more additional layers of drywall along the perimeter of the inner wall panel.

[00193] In alternative example embodiments, the upper longitudinal floor support beam 312 or the longitudinal floor support beam 313 may include thermal break elements between surfaces of these beams which would otherwise contact upper and lower surfaces, respectively, of the interior wall panels 314 and exterior walls panels 316. The thermal break elements are physical objects that reduce heat transfer across elements that contact opposing sides of the thermal break element. These thermal break elements aid in maintaining an internal temperature within areas of the structure that are adjacent to the wall panel system and portions of the ceiling system and floor system that are adjacent to the wall panel system and the thermal break elements. For example, the thermal break element may be a wooden beam, such as a 2x6 wooden beam, or another beam or physical object made of insulating material. An example of this is shown as spacer 1608s in FIG. 17 where the spacer 1608s may be made of material that provides thermal insulation and does not transmit heat well or the lower wood beam 2434p in the wooden structure 2434 for the wall panel system 2430 shown in FIGS. 24H- 24I.

[00194] Referring next to FIG. 5A, there is shown a rear view of a wall panel

500, which may be used as the interior wall panel 314 shown in FIGS. 3 or 4. The wall panel 500 has a panel section 501 with a rear surface 500a and also comprises left and right side sections extending away from the panel section

In at least one embodiment, there are a plurality of the interface components 506, 508 that are located and spaced apart along the length of the surfaces 502, 504, respectively, of the panel 500. This allows for more connections along the height of laterally adjacent panels thereby providing a more secure and stronger connection.

[00195] In at least one embodiment, the at least one second interface component 506, 508 may be a female connector, such as a slot 510, that is located and shaped to receive a male connector, such as a hook, of a corresponding exterior wall panel (e.g., wall panel 600 of FIGS. 6A-6D). An enlarged view of the slot 510 is shown in Detail A of FIG. 5A. In another embodiment, the at least one third interface component 506, 508 may be a male connector, such as a hook, that is shaped and located to engage with a female connector, such as a slot, of a corresponding exterior wall panel.

In at least one embodiment, the at least one first and second interface components 516 and 518 may be apertures for receiving bolts, screws, or other suitable releasable fasteners. In another embodiment, the at least one first and second interface components 516 and 518 may include a male portion and a female portion (such as, for example, the slot and tab interface component of the wall panels described in PCT patent application number PCT/CA2021/051031 filed on July 23, 2021 ), a screw connection, a slot and hook connection, or any other suitable releasable connection system. In at least one embodiment, there are a plurality of the interface components 516, 518 that are located and spaced apart along the length of the surfaces 512, 514, respectively, of the panel 500. This allows for more connections along the height of laterally adjacent panels thereby providing a more secure and stronger connection. [00197] In at least one embodiment, the left and right side surfaces 512, 514 may comprise slotted end portions 520 and 522 disposed along the bottom corner of the side surfaces 512 and 514 and the panel section 501 , respectively. The slotted panels 520 and 522 may be used to attach the wall panel 500 to a frame of the mobile unit 300, such as a bottom rail or an angle iron or L-angle. In at least one embodiment, the slotted panels 520 and 522 may also be used to attach the wall panel 500 to a floor system 310 of a mobile unit 300. The left and right side surfaces 512, 514 may further comprise apertures 524 and 526 disposed along the top portion of the sides surfaces 512, 514. The apertures 524 and 526 may be used to attach slings to allow the wall panel 500 to be lifted during construction.

The panel extension 620 may be used to attach the wall panel 600 to a frame of the mobile unit 300. For example, in at least one other embodiment, the panel extension 620 may be used to attach the wall panel 600 to the floor system 310 of the mobile unit 300.

[00204] Referring next to FIGS. 6C and 6D, there are shown perspective front and rear views of the wall panel 600, as well as a bottom view of the wall panel 600 comprising the left side section 611 having the left side surface 612 and the left rear surface 602, and a right side section 613 having the right side surface 614 and the right rear surface 604. The right rear surface 604 also includes at least one third interface component 606, the left rear surface 602 comprises at least one third interface component 608 and the left side surface 612 comprises at least one second interface component 616.

[00205] Referring next to FIG. 7, there is shown a perspective view of an example embodiment of an assembly 700 of multiple wall panels. In the shown embodiment, a first wall panel 702, such as wall panel 500 from FIGS. 5A-5D, is shown in co-planar connection with a second wall panel 704, which is also similar to wall panel 500 from FIGS. 5A-5D. A third wall panel 706, such as wall panel 600 from FIGS. 6A-6D, is shown that it is about to be arranged in a horizontally offset fashion with respect to wall panel 702. The first and second wall panels 702 and 704 may form a portion of the interior wall of the mobile unit 300. The third wall panel 706 may form a portion of the exterior wall of the mobile unit 300.

[00206] In this example embodiment, the first wall panel 702 and the second wall panel 704 are releasably connected along adjoining side surfaces 708 of each respective panel. For example, the first interface component 710 of the first wall panel 702 may be releasably coupled with a similar interface component of the second wall panel 704 by using a bolt. This is typically repeated along the extent of the side surfaces 708 by using other instances of these first interface components.

[00207] The first wall panel 702 and the third wall panel 706, in the assembly 700, may be releasably connected along the adjoining rear surfaces 712, 714, respectively, of each wall panel 702 and 706. In this example embodiment, the third interface component 716 of the rear surface 712 of the first wall panel 702 may be a slot connection and the third interface component 718 of the rear surface 714 of the third wall panel 706 may be a hook connection, as shown in FIG. 7, that releasably engages the slot connection 716. This is typically repeated along the extent of the rear surfaces 712 and 714 by using other instances of these interface components.

[00208] Referring next to FIG. 8, there is shown a perspective view of an example embodiment of an assembly 800 of multiple interior and exterior wall panels. In the shown embodiment, there is a first wall panel 802 and a second wall panel 804 that are releasably connected in a co-planar manner as was described for wall panels 702 and 704 of FIG. 7. The first and second wall panels 802 and 804 may form a portion of the interior wall of a custom enclosure such as the mobile unit 300. A third wall panel 806 and a fourth wall panel 808 are also shown in co-planar connection, while horizontally offset from the first wall panel 802 and the second wall panel 804. The third and fourth wall panels 806 and 808 may form a portion of the exterior wall of a custom enclosure such as the mobile unit 300. The wall panels 802 and 806 are being positioned for releasable connection to one another in a horizontally offset manner as was described for wall panels 702 and 706 of FIG. 7.

[00209] Referring next to FIGS. 9A and 9B, there are shown a perspective view and a semi-transparent perspective view, respectively, of an example embodiment of an assembly 900 of connected wall panels 902 and 904. In this example embodiment shown, the first wall panel 902 is releasably connected with a second wall panel 904 in a horizontally offset fashion while there remains a space or cavity 905 between the two panels which may receive building components such as, but not limited to, electrical wiring, pipes, electrical devices including, but not limited to, sound measuring and pressure control devices and/or insulation, for example. FIG. 9A further shows a first interface component 906 of the first wall panel 902 to potentially allow for co-planar connection with another wall panel, an example of which was shown in FIG. 7. As can be seen in FIG. 9A, the hook 906 is formed by making a cut in a portion of the side wall section portion 914 to form a tab, pushing the tab away from the side wall section 914, and making a slit at a bottom of the tab to form a hook. The size of the slit is such that the bottom portion of the hook releasably slidably engages a corresponding slot attachment on another wall panel.

[00210] Shown in FIG. 9B is a partial transparent view of panel 904 which allows the interface components 908 and 910 to be seen which are used to releasably connect the first wall panel 902 and the second wall panel 904. In the embodiment shown, the interface components 908 and 910 are an example of a hook and slot connection. The hook may be formed as described for the first interface component 906 such that there is a slit that is sized to releasably slidably engage the slot of the corresponding interface component 910. In other embodiments, the interface components 908 and 910 may be, for example, another type of male and corresponding female connections, such as a slot and tab connection (such as, for example, the slot and tab interface component of the wall panels described in PCT patent application number PCT/CA2021/051031 filed on July 23, 2021 ), or any other appropriate releasable connection system. [00211] Referring next to FIG. 10, there is shown a partial transparent top perspective view of a wall panel system 1000 in which there is a releasable connection of four wall panels including a first wall panel 1002 that is in coplanar (i.e., lateral) connection with a second wall panel 1004 and in a horizontally offset parallel connection with a third wall panel 1006. The third wall panel 1006 is releasably connected in a co-planar manner with a fourth wall panel 1008, and the fourth wall panel 1008 is releasably connected in a horizontally offset manner with the second wall panel 1004.

[00212] Referring now to FIGS. 11 A-11 E, shown therein are various views of an example of an alternative embodiment of an interior wall panel 1100 for use in a double-panel wall system in accordance with the teachings herein. The wall panel 1100 has a panel section 1101 with a rear surface 1100a, a front surface 1100b, and also left and right side sections that extend away from the panel section 1101 , where each left and right side section has a fold section to provide rear surfaces 1102 and 1104, respectively. Each of the left and right side sections have left and right side surfaces 1112 and 1114, respectively, that have at least one first and second interface components 1116 and 1118, respectively. Each rear surface 1102 and 1104 comprises at least one third interface component 1106, 1108. The first interface components 1106 and 1108 enable the interior wall panel 1100 to be releasably connected to another similar interior wall panel in a laterally offset fashion to create a larger interior wall section. Each of the second interface components 1106 and 1108 allow the interior wall panel 1100 to be connected to an exterior wall panel in a horizontally offset fashion such that the panel sections of these horizontally offset wall panels are spaced apart and parallel to one another, an example of which is shown in FIGS. 13C-13D. In at least one embodiment, there are a plurality of the interface components 1106, 1108 that are located and spaced apart along the length of the surfaces 1102, 1104, respectively, of the panel 1100. This allows for more connections along the height of laterally adjacent panels thereby providing a more secure and stronger connection. [00213] In at least one embodiment, the at least one first and second interface components on one side surface 1112 of the wall panel 1100 may be a male connector 1116a and there is a cutout 1116b that is left behind when the male connector 1116a is cut from and pulled away from the left side surface 1112. The male connector 1116a is in the form of a hook and it is oriented so that there is a slit 1116s between the bottom of the hook and the adjacent side surface 1112. The at least one second interface component 1118 on the other side surface 1114 of the wall panel 1100 may be a female connector that is shaped to receive a male connector. In this example embodiment, the at least one second interface component 1118 is a slot. Accordingly, the interface components on one side surface of the interior wall panel 1100 include male connector types while the interface components on the other side surface of the interior wall panel 1100 include female type connectors so that the interior wall panels 1100 can be laterally coupled to one another to form a larger (i.e., longer) wall section.

[00214] In another embodiment, the at least one first and second interface components 1116, 1118 may instead be female and male connectors, respectively, where the female connectors may be as a slot, that is shaped and located to engage with a corresponding male connector, such as a hook, of an adjacent interior wall panel. In another embodiment, the at least one first interface components 1106, 1108 may each include both a male portion and a female portion such as, for example, the slot and tab interface component of the wall panels described in PCT patent application number PCT/CA2021/051031 filed on July 23, 2021 , a screw connection, a bolt connection, or any other suitable releasable connection system. In at least one embodiment, there are a plurality of the interface components 1116, 1118 that are located and spaced apart along the length of the surfaces 1112, 1114, respectively, of the panel 1100. This allows for more connections along the height of laterally adjacent panels thereby providing a more secure and stronger connection. [00215] In at least one embodiment, the second interface components 1106 and 1108 may be a female connector, such as a slot, that is located and shaped to receive a male connector, such as a hook, of a corresponding exterior wall panel (e.g., wall panel 1200 of FIGS. 12A-12D). The slot of each second interface connector 1106 and 1108 includes slits 1107 and 1109, respectively, at a bottom portion thereof to allow for some flexibility when engaged by a male connector to allow for differences in manufacturing tolerances. An enlarged view of the third interface component 1108 is shown in FIG. 11C and an enlarged view of the first interface component 1116 is shown in FIG. 11 D.

[00216] In another embodiment, the at least one second interface component 1106, 1108 may instead be a male connector, such as a hook, that is shaped and located to engage with a corresponding female connector, such as a slot, of a corresponding exterior wall panel. In another embodiment, the at least one third interface components 1106, 1108 may each include both a male portion and a female portion such as, for example, the slot and tab interface component of the wall panels described in PCT patent application number PCT/CA2021/051031 filed on July 23, 2021 , a screw connection, a bolt connection, or any other suitable releasable connection system.

[00217] In this example embodiment, the wall panel 1100 also includes a prefabricated cutout or aperture 1103 in the panel section 1101 that may be used to pass wires therethrough for various items such as, but not limited to power outlets, cables for communication outlets or other electrical components, air lines, gas lines, communication lines, power lines or any other mechanical and/or electrical infrastructure, for example. Alternatively, mechanical components such as a vent may be situated at the aperture 1103. It should be noted that aperture 1103 is optional.

[00218] The wall panel 1100 also includes other prefabricated apertures or cutouts on the sidewall sections such as apertures 1105a, 1105b only two of which are labelled for simplicity of illustration. The apertures 1105a, 1105b may also be used to pass electrical wires, communication cables, air lines, gas lines, power lines or other mechanical and/or electrical infrastructure components between adjacent interior wall panels. Advantageously, the apertures 1105a, 1105b enable a time savings during construction because once adjacent interior wall panels 1100 are coupled together the above-noted elements can be easily passed from one interior wall panel to an adjacent wall panel using the precut apertures 1105a, 1105b as the cutouts are premade and aligned for adjacent wall panels so there is no need for additional wall cutting which reduces installation time. In at least one embodiment, apertures 1105a, 1105b can be laser cut.

[00219] Referring again to FIGS. 11A and 11 D, the left and right side surfaces 1112 and 1114 may comprise slotted end portions 1120 and 1122, respectively, disposed along the corners of the bottom portion 1103 of the wall panel 1100. The slots 1120 and 1122 are shaped to receive a connection member to connect the wall panel 1100 to a portion of a floor system of a custom enclosure. In this example embodiment, the slots 1120 and 1122 have an L- shape for releasably engaging an angle iron (not shown) or an L-shaped beam where the angle iron/L-shaped beam is generally attached (e.g., screwed or bolted) to a portion of a floor system or a frame of a custom enclosure. Alternatively in other embodiments, the slots 1120 and 1122 may have a different shape such as just a vertical slot or an angled slot depending on the orientation of the floor connection member which the slots 1120 and 1122 slidably engage.

[00220] In at least one alternative embodiment, the wall panels may employ optional reference holes that are used as guides for the placement of tools that are used to form various cutouts for certain interface components such as male interface components. An example of this is shown in FIG. 11 D with optional references holes 1100h1 and 1100h2 that are located above and/or below the location where the cutout is to be made. The holes 1100h1 and 1100h2 may also be referred to as technological holes. The shape of the cutout is dictated by the tool that is used and so the shape of the cutout can be altered by using a different tool. These reference holes allow the tool to be accurately located to form cutouts (and in this example also tabs) with the same size and shape every time to provide a consistent manufacturing process. The reference holes can be any shape and is not limited to circles. Such reference holes may be laser cut.

[00221] Referring now to FIGS. 12A-12E, shown therein are various views of an example embodiment of an exterior wall panel 1200 for use in a doublepanel wall system in accordance with the teachings herein. The wall panel 1200 has a panel section 1201 with left and right side sections that extend away from the panel section 1201 . Each of the left and right side sections have a rear fold portion that provides rear surfaces 1202 and 1204, respectively. Each of the left and right side sections also have left and right side surfaces 1212 and 1214, respectively, between the panel section 1201 and the rear fold surfaces 1202 and 1204, with at least one first and second interface components 1210 and 1218, respectively. In at least one embodiment, there are a plurality of the interface components 1218, 1210 that are located and spaced apart along the length of the surfaces 1212, 1214, respectively, of the panel 1200. This allows for more connections along the height of laterally adjacent panels thereby providing a more secure and stronger connection.

[00222] In at least one embodiment, the at least one second interface component 1218 of the left side surface 1212 may have a female connection such as a rectangular cutout, or the like, and the at least one first interface component 1210 of the right side surface 1214 may have a male connection such as a hook, or the like, to enable multiple exterior wall panels similar to wall panel 1200 to be releasably connected to one another in a co-planar manner to form a larger (i.e. , longer) wall segment. In such embodiments, the hook, or other male connector, on the right side surface 1214 of a given wall panel similar to wall panel 1200 may be received by the slot or other corresponding female connector on the left side surface 1212 of another adjacent wall panel similar to wall panel 1200. The wider opening of the at least one second interface component 1218, provided by lateral extension cutout, an example of which is labelled as 121 Oe, which is a slide slot that may extend up to a bend where rear surface 1202 is formed, aids in releasably attaching an exterior wall panel to a previously installed adjacent exterior wall panel and an opposing interior wall panel (or intermediate wall panel as discussed below) at the same time.

[00223] It should be noted that the slots 1218 are wider and cover more than about 50% of the side surface area in this embodiment which allows the hook of an adjacent exterior wall panel to be moved a greater distance horizontally to provide more flexibility in positioning the adjacent exterior wall panel for releasably coupling it to another exterior wall panel as well as releasably coupling it to a horizontally offset interior wall panel (an example of this is shown in FIGS. 14A-14B).

[00224] Each rear surface 1202, 1204 of the wall panel 1200 comprises at least one third interface component 1206, 1208 to enable the exterior wall panel 1200 to be releasably connected/coupled to corresponding rear surfaces of an interior wall panel 1100 in a horizontally offset fashion such that the inner surfaces of the panel sections of these wall panels 1200 and 1100 are spaced apart and the panel sections may be generally parallel to one another. In at least one embodiment, the at least one third interface component 1206, 1208 may be a male connector 1206a, 1208a such as a hook, for example, that is releasably received by a female connector 1108, such as a slot, of interior wall panel 1100. Enlarged view of the hooks 1208a and 1206a are shown in FIGS. 12C and 12D, respectively. Alternatively, in at least one other embodiment, the at least one third interface component 1206, 1208 may be a female connector, such as a slot, that is located and shaped to receive a corresponding male connector, such as a hook, which may be on an alternative embodiment of an interior wall panel. Alternatively, in at least one other embodiment, the at least one third interface component 1206, 1208 may have both a male portion and a female portion (such as, for example, the slot and tab interface component of the wall panels described in PCT patent application number PCT/CA2021/051031 filed on July 23, 2021 ), a screw connection, a bolt connection, or any other suitable releasable connection system, with corresponding connectors being on an alternative embodiment of an interior wall panel. In at least one embodiment, there are a plurality of the interface components 1206, 1208 that are located and spaced apart along the length of the surfaces 1202, 1204, respectively, of the panel 1200. This allows for more connections along the height of laterally adjacent panels thereby providing a more secure and stronger connection.

[00225] In at least one embodiment, there may be a panel extension 1203 along the bottom of the panel section 1201 as shown in FIGS. 12A-12B. The panel extension 1203 may be used to attach the exterior wall panel 1200 to a portion of a custom enclosure. For example, in at least one embodiment, the panel extension 1203 may be used to attach the wall panel 1200 to a floor system, an example of which is shown and discussed with respect to FIGS. 21A-21 E.

[00226] Referring now to FIGS. 13A-13B, shown therein are various views of a portion of a wall system 1300 having two interior panels 1302 and 1304, that are similar to interior wall panel 1100, and are releasably coupled together. The interior wall panel 1304 includes a cutout 1103 in a portion of its panel section while the interior wall panel 1302 does not include this cutout. As can be seen in FIG. 13B, the interior wall panel 1302 has a side surface 1306 with a female connector 1308 and a cutout 1312 as well as a rear surface 1307 with a female connector 1308 with slits 1310. FIG. 13B also shows that the interior wall panel 1304 has a side surface 1314 with a male connector 1316 and a cutout 1322 as well as a rear surface 1317 also with a female connector 1318 and slits 1320. The male connector 1316 is a hook with a width that is slightly less than the width of the female connector 1308 which is a slot. The male connector 1316 is releasably engaging the female connector 1308. During assembly, the wall panel 1304 may be positioned slightly higher than the wall panel 1302 and moved towards the wall panel 1302 such that the male connector 1316 enters the top/upper portion of the slot 1308, the side surfaces 1316 and 1314 are adjacent to one another and the wall panel 1300 is then lowered so that the hook 1316 engages the upper surface of the bottom portion of the slot 1308. This also results in the cutouts 1312 and 1322 aligning with one another so that pipes, electrical elements like wires or cables, or other building functional components like other mechanical and/or electrical infrastructure components, can be passed therethrough.

[00227] Referring now to FIGS. 13C-13D, shown therein are upper perspective views of portion of a double-panel wall section 1350 with an exterior panel 1352 at first and second positions, respectively, when being releasably coupled to an interior panel where the exterior panel corresponds to the exterior panel 1200 and the interior panel corresponds to the interior panel 1100. The exterior wall panel 1352 has a side surface 1356 with a female connector 1360 and a rear surface 1358 with a male connector 1362. FIG. 13C also shows that the interior wall panel 1354 has a side surface 1364 with a female connector 1372 and a rear surface 1366 also with a female connector 1368 and slits 1370. The male connector 1362 is a hook with a width that is slightly less than the width of the female connector 1368 which is a slot. The male connector 1362 is releasably engaging the female connector 1308. During assembly, the wall panel 1352 may be positioned slightly higher than the wall panel 1354 and moved towards the wall panel 1302 such that the male connector 1362 enters the top portion of the slot 1368, the rear surfaces 1358 and 1366 are adjacent to one another and the wall panel 1352 is then lowered so that the hook 1362 engages the upper surface of the bottom portion of the slot 1368 as shown in FIG. 13D. It can also be seen that there is a cavity between exterior and interior wall panels that are releasably connected to one another that includes cavity 1354c associated with wall panel 1354 and cavity 1352c associated with wall panel 1352. The cavity 1354c of the interior wall panel 1354 may be used to house various elements such as any combination of electrical components, mechanical components, vent components, pipes and other electrical and/or mechanical infrastructure components. The cavity 1352c for the exterior wall pane 1352 may be used to contain other materials such as insulation material, for example, or other types of mechanical, electrical and/or infrastructural components as discussed with respect to FIG. 14G. [00228] Referring now to FIGS. 14A-14B, shown therein are upper perspective sectional views of a portion of double wall system 1400. FIG. 14A shows exterior wall panel 1352 being releasably connected to a double wall panel assembly in which exterior wall panel 1402 is already releasably coupled to interior wall panel 1404, and interior wall panel 1354 is already releasably connected to interior wall panel 1404. FIG. 14B shows a section of the double wall panel system in which: (a) adjacent interior wall panels releasably engage one another laterally, (b) exterior wall panels releasably engage one another laterally and (c) interior and exterior wall panels that are horizontally opposite one another releasably engage one another. For instance, as shown in this example, two interior panels 1354 and 1404 releasably engage one another laterally, two exterior panels 1352 and 1402 releasably engage one another laterally, exterior and interior panels 1352 and 1354 are opposite one another and releasably engage one another, and exterior and interior panels 1402 and 1404 are opposite one another and releasably engage one another. The exterior wall panels 1352 and 1402 are similar to exterior wall panel 1200 and the interior wall panels 1354 and 1404 are similar to interior wall panel 1100.

[00229] Referring to FIG. 14A, the exterior wall panel 1352 includes a female connector (i.e., wide slot) 1360 on a side surface and a male connector 1362 on a rear surface. The term “wide slot” means that a slot is at least about two to about five times as big, for example, as the width of a male connector that releasably engages the "wide slot" depending on the amount of real estate available for the placement of the slow. The interior wall panel 1354 includes a female connector (i.e., narrow slot) 1368 on a rear surface with slits 1370 at a lower portion thereof. The term “narrow slot” means that a slot is not as wide as or is narrower than a “wide slot” and a “narrow slot" is just a bit wider than the width of a male connector that releasably engages the “narrow slot” (e.g., about 5 to 10% larger or so enough to account for manufacturing tolerances while allowing for a near friction -fit). The exterior wall panel 1402 includes a male connector 1408 extending in a direction that is opposite the direction of the male connector 1362 on the rear surface of the adjacent exterior wall panel 1352. For example, the male connector 1362 may have a hook member pointed downwards and the male connector 1408 may have a hook member pointed upwards. Thus, male connectors 1362 and 1408 point or are directed towards opposite directions which allows the exterior wall panel 1352 to releasably engage a laterally offset exterior wall panel 1402 at the same time as a horizontally offset interior wall panel 1354. This is partly enabled by the wider female connector 1360 since the exterior wall panel 1352 can be first moved towards the exterior wall panel 1402 such that the male connector 1408 moves through the female connector 1360 near the front edge or mid portion of the female connector 1360 until the side surface of the wall panel 1352 moves adjacent to the side surface of the adjacent wall panel 1402 (here the front edge of the female connector 1360 is closer to the panel section of the wall panel 1352). Next, the exterior wall panel 1352 is then moved towards the interior wall panel 1354 such that the male connector 1408 moves laterally along the female connector 1360 towards the rear edge of the female connector 1360 while the male connector 1362 moves through the female connector 1368 of the interior wall panel 1354 near the top portion of the female connector 1368 and the rear surface of the exterior wall panel 1352 becomes adjacent to the rear surface of the interior wall panel 1354. During this movement, the male connector 1408 of the exterior wall panel 1402 is now positioned near the rear edge of the female connector 1360 as is shown in FIG. 14A. The exterior wall panel 1352 is then lowered such that the male connector 1408 of the exterior wall panel 1402 now engages the upper portion of the female connector 1360 of the exterior wall panel 1352 while the male connector 1362 now engages the lower portion of the female connector 1368 of the wall panel 1354 as is shown in FIG. 14B. Accordingly, the narrower width (i.e. narrow slot) of the female connector 1368 allows for vertical movement of the male connector 1362 of the exterior wall panel 1352 while the wider width and the height of the female connector 1360 (i.e. wide slot) of the exterior wall panel 1352 allows for both vertical and horizontal movement of the exterior wall panel 1352 relative to the male connector 1408. The use of the various male and female connectors on the wall panels 1352, 1354, 1402 and 1404 allow these wall panels to be directly coupled to one another. [00230] In at least one embodiment, the space between horizontally offset exterior and interior wall panels, such as wall panels 952 and 956 or between wall panels 1352 and 1354, for example, may be used to house electrical equipment, piping for air or water, communication cables, insulation, electrical devices including, but not limited to, sound measuring and pressure control devices, or any other functional and/or mechanical infrastructure components needed for use within the mobile unit 300 or any another custom enclosure.

[00231] It should also be noted that the piecewise releasable connection of interior wall panels and exterior wall panels means that one or more interior wall sections of the mobile unit 300, or another custom enclosure, may be formed first before any exterior wall panels are releasably coupled to the wall panels of the interior wall sections. This then allows for work to be conducted on the inside of the mobile unit 300, or other custom enclosure, while the entire double-panel wall system is not fully completed. For example, the interior wall panels may be put in place originally and work may continue on the inside of the mobile unit 300, while insulation, wires, electrical necessities, piping, electrical devices including, but not limited to, sound measuring and pressure control devices, or any other functional and/or mechanical infrastructure components are installed at the outer surfaces of the interior wall panels. Once this is completed the exterior wall panels may then be installed to complete the wall structures of the mobile unit 300 or other custom enclosure.

[00232] Referring now to FIGS. 14C-14E, shown therein are front and rear perspective views of portions of alternative example embodiments of interior wall panels 1430 and 1440, respectively, which are similar to the interior wall panel 1100 but have interface components that are laterally offset or laterally staggered from one another on at least one side surfaces thereof. Accordingly, similar elements for wall panels 1100, 1430 and 1440 use similar reference numerals in the figures.

[00233] For example, in FIG. 14C, the alternative interior wall panel 1430 has an interface component 1116 that is similar to that of interior wall panel 1100, but there is another interface component 1432, which may be about midway along the length of the side surface 1112 where it is situated closer to the rear surface 1102 compared to the front surface 1100b. The interface component 1432 includes a male connector 1432a and a cutout 1432b that is left behind when the male connector 1432a is cut from and pulled away from the left side surface 1112. The male connector 1432a may be shaped like male connector 1116a for the reasons given when the male connector 1116a was described. Although the right side surface of the interior wall panel 1430 is not shown, it should be understood that it may have interface connectors that are female connectors (i.e. , slots) similar to slot 1118 that was shown for interior wall panel 1100 (see FIG. 11 C) except that the slots on the right side surface are also laterally offset or laterally staggered at approximately the same locations as the interface components on the left side surface 1112. This allows the interface components of the interior wall panel 1430 to be releasably coupled to corresponding interface components on a similar adjacent interior wall panel (not shown) that are also laterally offset in a corresponding manner (e.g., at the same position). It should be noted that use of the term “corresponding manner” here means that the interface components on the adjacent interior wall panel are shaped and positioned to releasably mate with the laterally staggered interface components of the wall panel 1430. The laterally staggered interface components 1116 and 1432 provide for increased structural stability. There may be two or more staggered interface components on the side surfaces of the interior wall panels 1432. It should be noted that other than the staggered nature of the interface components 1432 (and corresponding slots on the other side surface) for the interior wall panel 1430, the various alternatives for the interface components described for interior wall panel 1100 also apply to the staggered interface components of interior wall panel 1430.

[00234] Referring now to FIG. 14D, the alternative interior wall panel 1440 is similar to the alternative interior wall panel 1430 except that the staggered interface components 1116 and 1442 are positioned much closer to one another vertically, or in other words along the length of the side surface 1112, such that they may be referred to as a pair of laterally staggered interface components positioned near an end portion of the interior wall panel 1440. The pair of laterally staggered interface components may be at a lower end portion of the side surface 1112, an upper end portion of the side surface 1112, one or more locations between the upper and lower end portions of the side surface 1112 or combinations thereof. The interface component 1442 also includes a male connector 1442a and a cutout 1442b similar to male connector 1432a and a cutout 1432b, respectively. Similarly, other than showing a different longitudinal spacing (i.e., vertical spacing) between the interface components 1116 and 1442 along the side surface 1112 of the interior wall panel 1440, the rest of the description for interior wall panel 1430 also applies to interior wall panel 1440 such as how the interior wall panel 1440 may be laterally releasably coupled with a similar interior wall panel (i.e., having corresponding or mating interface components at the same location along its side surfaces) and the alternative embodiments for the interface components 1106, 1116 and 1442.

[00235] Referring now to FIG. 14E, shown therein is a rear perspective view of a portion of an alternative example embodiment of an exterior wall panel 1450, which is similar to exterior wall panel 1200 except for the use of staggered interface components on the side surfaces thereof. Accordingly, similar elements for wall panels 1100, 1430 and 1440 use similar reference numerals in the figures. The exterior wall panel 1450 has staggered interface components 1210 and 1452, which may be referred to as a pair of laterally staggered interface components. Interface component 1452 includes a male connector 1442a and a cutout 1442b similar to male connector 1210a and cutout 1210b, While the interface components 1210 and 1452 are closely longitudinally spaced similar to the spacing of interface components 1116 and 1442, there may be other embodiments where the spacing between successive interface components on the side surface are increased, such as what is shown in FIG. 14C, for example. The pair of laterally staggered interface components may be at a lower end portion of the side surface 1214, an upper end portion of the side surface 1214, one or more locations between the upper and lower end portions of the side surface 1214 or combinations thereof. Alternatively, the staggered interface components may be located as shown in FIG. 14C for the interior wall panel 1430. Similarly, the rest of the description for exterior wall panels 1430 and 1440 also applies to exterior wall panel 1450 in terms of how the exterior wall panel 1450 may be laterally releasably coupled with similar exterior wall panels (i.e., having corresponding interface components I mating interface components at the same location along its side surfaces) and the alternative embodiments for the interface components 1106, 1116 and 1442.

[00236] It should be understood that the various depictions of staggered interface components shown and described hereon are just provided as examples and there can be other embodiments in which the interface components are laterally offset/l ate rally staggered in a different manner, for example, in terms of the number of interface components and their proximity to one another on a given side surface of a wall panel.

[00237] Referring now to FIG. 14F, shown therein is a rear perspective view of an example embodiment of an intermediate wall panel 1460 for use in forming a multi-panel wall system, an example of which is shown in FIG. 14G, in accordance with the teachings herein, where “multi” means more than two. The intermediate wall panel 1460 is similar in structure as the exterior wall panel 1200 except that it does not include the panel extension 1203. Accordingly, the intermediate wall panel 1460 is able to releasably engage an interior wall panel such as interior wall panel 1100. Also, although not shown in FIG. 14F, there may be alternative embodiments of the intermediate wall panel 1460 which include staggered interface components on side surfaces thereof as was explained for the exterior wall panel 1450. However, the intermediate wall panel 1460 includes additional interface components through the wall panel section (i.e., the additional interface components extend from the front surface to the rear surface of the wall panel section near side end portions of the front and rear surfaces of the panel section). For simplicity of illustration one of these additional interface components is labelled 1464. The additional interface components may also be referred to as intermediate interface components. While three intermediate interface components are shown near the far right and far left sides of the front/rear surfaces of the intermediate wall panel 1460 in FIG. 14F, there may be other embodiments with one intermediate interface component, two intermediate interface components or more than three intermediate interface components. Although not visible in FIG. 14F, it should be understood that there are similar intermediate interface components that extend through the panel section of the wall panel near the other side surface of the exterior wall panel 1460.

[00238] The number and location of the intermediate interface components 1464 may correspond with at least two interface components 1208 on the rear surface 1204 of an exterior wall panel or another intermediate wall panel and at least two interface components 1206 on the rear surface 1202 of an exterior wall panel or another intermediate wall panel. The intermediate interface components 1464 may be slidably engaged by correspondingly located interface components on the rear surface of an exterior wall panel or another intermediate wall panel which may occur in a similar manner as was described when an interior wall panel is being engaged by an exterior wall panel, an example of which was described with respect to FIGS. 13C-13D.

[00239] In use, the intermediate wall panel 1460 may releasably engage with an interior wall panel, such as wall panel 1100, in a horizontally offset manner and then an exterior wall panel, such as wall panel 1200, may releasably engage the interior wall panel 1460 also in a horizontally offset manner. This may be referred to as a three-panel wall system. An example of this, referring to FIG. 14G, is interior wall panel 1472, intermediate wall panel 1474 and then exterior wall panel 1478 with no intermediate wall panel 1476. The interior wall panel 1472 may be laterally releasably engaged with other interior wall panels as was described in for interior wall panels 1302 and 1304 as shown in FIGS. 13A-13B, for example. Likewise, the intermediate wall panel 1474 may be laterally releasably engaged with other intermediate wall panels in a similar manner as was shown for exterior wall panels 1302 and 1402 in FIGS. 14A- 14B. Likewise, the exterior wall panel 1476 may be laterally releasably engaged with other exterior wall panels in a similar manner as was shown for exterior wall panels 1302 and 1402 in FIGS. 14A-14B. Therefore, a large section of a three-panel wall system can be made having a desired length by laterally releasably coupling similar wall panels in each layer or row of wall panels while also coupling opposite wall panels in adjacent rows together in a horizontally offset manner.

[00240] Accordingly, a multi-wall panel structure may be extended by releasably coupling additional intermediate wall panels in a horizontally offset manner where the innermost wall panel is an interior wall panel, the outermost wall panel is an exterior wall panel and there can be one or more intermediate wall panels that are all horizontally offset from one another. Each of these wall panels may then be laterally releasably coupled to like-manner wall panels to create a larger wall section as explained previously. For example, a four-panel wall system is shown in FIG. 14G where there is a first wall panel layer of interior wall panels including interior wall panel 1472, a first intermediate wall panel layer including intermediate wall panel 1474, an additional intermediate wall panel layer of intermediate wall panels including intermediate wall panel 1476 and a final wall panel layer of exterior wall panels including exterior wall panel 1478.

[00241] In at least one embodiment, the intermediate wall panels may be formed using the exterior wall panels 600 (e.g., see FIGS. 6A-6D) and adding the intermediate interface components and removing the extension portions as was described for intermediate wall panel 1460 having intermediate interface components 1464.

[00242] Advantageously, one or more intermediate wall panel layers may be used to provide additional properties to the multi-panel wall system by using different materials for the intermediate and/or exterior wall panels or placing different materials within the cavities formed between (a) two horizontally offset intermediate wall panels for wall panel systems with at least two intermediate wall panel layers and/or (b) horizontally offset exterior and interior wall panels.

[00243] As an example, again as shown in FIG. 14G, the cavities formed between horizontally offset interior and intermediate wall panels may be used for passing various electrical, mechanical and/or infrastructure components as was described in previous embodiments where an exterior wall panel was horizontally offset from an interior wall panel. For example, these components can be electrical wiring, communication cables, power cables, gas lines, and/or any other mechanical, electrical and/or structural components.

[00244] However, depending on the use of the custom enclosure which is built using the multi-panel wall system, the intermediate and/or exterior wall panels may be made of certain materials and/or have certain surface coatings. Alternatively, or in addition thereto, certain materials can be placed within the cavities formed between two horizontally offset intermediate wall panels and/or the cavities formed between horizontally offset intermediate and exterior walls panels to allow the custom enclosure to have certain properties and/or certain ratings such as a certain fire ratings, certain insulation ratings, certain safety ratings, certain sound ratings or any combination thereof.

[00245] For example, if the custom enclosure is used in an environment that is especially cold then additional insulation may be placed within one or more of these cavities (which are the shaded regions shown in FIG. 14G). Alternatively, or in addition thereto, for safety purposes, the intermediate and exterior wall panels may be made of fire retardant material and/or coated with fire retardant coatings and optionally fire resistant material may be inserted into the cavities

[00246] In another example, the custom enclosure that incorporates the multi-panel wall system may be used in applications where there is a risk of explosions or in areas where there is live ammunition. In such cases, the aforementioned cavities may have materials that are selected to handle/withstand different aspects of this environment. For example, as shown in FIG. 14G, one or more of the cavities between horizontally offset, releasably coupled exterior and intermediate wall panels may optionally be filled with material that can absorb an impact from an explosion and may be referred to as the explosion absorbing wall panel layer. Alternatively, or in addition thereto, one or more cavities between two horizontally offset, releasably coupled intermediate wall panels may optionally use material that is bullet resistant and be referred to as the bullet proof wall panel layer. Alternatively, or in addition thereto, the cavities within one or more intermediate panels that are horizontally offset and releasably coupled to interior wall panels or the interior wall panels themselves may be used for other purposes such as containing insulation material while the cavities of the one or more interior or intermediate wall panels can be used for routing different components as described previously. Selecting materials having the desired properties such as, but not limited to, explosion or impact absorbing, bullet resistant and/or insulation, for example, may be done using off the shelf materials.

[00247] It should be noted that for all of the various wall panel embodiments described herein, the depths (e.g., length of the side surface) of the interior, exterior and intermediate wall panels may be selected to be the same. However, in some embodiments, different types of wall panels may have different depths which will allow more material to be used within the cavities of those wall panels. For example, the depth of the exterior wall panels may be selected to be larger than the depth of the interior wall panels. For instance, not limited to the following example, the exterior wall panels may have a depth of about 4 to 5 inches and the interior wall panels may have a depth of about 2 to 3 inches. This increased depth may be used to insert more insulation adjacent the inner surface of the wall panel section of the exterior wall panels to provide for more insulation for the custom enclosure that uses these panels. Alternatively, the intermediate wall panels may have a depth that is larger than the depth of the interior wall panels and/or the exterior wall panels. Alternatively, when there is more than one intermediate wall panel layer, the intermediate wall panels used for one layer, such as the intermediate wall panels 1476 used in the bullet resistant wall panel layer of FIG. 14G, may be larger than the depth of the intermediate wall panels used in another layer, such as the intermediate wall panel 1474 used in the insulation wall panel layer.

[00248] It should be noted that the wall panels described herein may be referred to as having different wall panel types where one wall panel type is an interior wall panel type, another wall panel type is an exterior wall panel type and another wall panel type is an intermediate wall panel type. These wall panel types are similar in that they have interface components on side surface and bended rear surfaces that allow for lateral releasable connection with a wall panel having the same wall type and for horizontally offset releasable connection with wall panels of another wall panel type. Additionally, the intermediate wall panel type includes additional interface components that extend through the front and rear surfaces of the panel section to allow for horizontally offset releasable connection with another wall panel type (e.g., interior or exterior wall panel types) or the same wall panel type (e.g., intermediate wall panel type).

[00249] Referring now to FIGS. 15A-15C, there is shown multiple views of an example embodiment of a roof panel 1500 that may be used to construct a roof system for mobile unit 300 or another custom enclosure, in accordance with the teachings herein. For example, FIG. 15A shows a right view, a bottom view, a left view and a top view, respectively, while FIG. 15B shows right and left perspective views, respectively, and FIG. 15C shows a top view.

[00250] The roof panel 1500 comprises a roof section 1501 having a bottom surface 1502 and an upper surface 1504, as well as a first side section 1506 having a side surface 1511 and a second side section 1508 having a side surface 1513 that both extend away from the upper surface 1504 of the roof section. The first side section 1506 comprises a first connecting component having a first lateral portion 1510. The second side section 1508 comprises a second connecting component having a second lateral portion 1512. The second lateral portion 1512 may be slightly smaller in length than the first lateral portion 1510. The first connecting component further has a first transverse extent 1514 extending from the first lateral portion 1510 thereby providing the first connecting component forms a channel 1510c. The roof panel 1500 may generally have a width between about 16 and about 24 inches and a length between about 96 and about 144 inches. Alternatively, for certain applications in which the mobile unit 300 or other custom enclosure is smaller or larger, the roof panel 1500 may have other dimensions. [00251] In at least one embodiment, the roof panel 1500 may be releasably connected with a similar roof panel which may be adjacent and interconnected to either of the side sections 1506 and 1508. In addition, another similar roof panel may be releasably connected to the other side section of the roof panel 1500 (an example of which is shown in FIG. 16A). The first connecting component of the first roof panel 1500 may be placed over the second connecting component of an adjacent roof panel such that the first lateral portion 1510 encompasses the entirety of the second lateral portion 1512, thereby forming a friction fit therebetween. This connection may provide structural integrity to a resulting roof structure/roof system made using the roof panels 1500 while not requiring a truss for support underneath the roof panels 1500. Alternatively, in some embodiments, depending on the size of the roof system, one or more trusses may be used as described further below. The connection components of the roof panels 1500 are structured to avoid deflections of the roof panels 1500 from varying loads and thus provide a similar function as a truss. For example, once a plurality of these roof panels 1500 are connected together, depending on the material used for the roof panels 1500, the roof panel system may hold up the weight of a human standing on it.

[00252] The overlapping nature of the first connecting component over the second connecting component may also allow for the connections between adjacent roof panels 1500 to provide partial or full water resistance from various weather elements such as rain or snow. However, in at least one embodiment, further weather proofing may be done by applying sealant at the areas where the edges of a given roof panel 1500 end over adjacent roof panels.

[00253] In at least one embodiment, the various connections between adjacent roof panels 1500 may be further secured by using fasteners such as screws, bolts, nails, staples, or any other securing device.

[00254] Referring now to FIG. 16A, there is shown a perspective view of a roof system 1600. FIG. 16A shows multiple roof panels 1602a-1602c, a ceiling panel 1604, and a longitudinal support beam 1606. The roof panels 1602a- 1602c are typically similar to the roof panel 1500. It should be noted that only a few of the roof panels 1602-1602c are labelled for simplicity and that there are multiple ceiling panels although only one is shown. Furthermore, it should be understood that there may be several longitudinal support beams that are arranged sequentially to cover the length of the mobile unit 300 or custom enclosure. Also, it should be noted that there are one or more other longitudinal support beams at the other side of the roof system for the other side wall which is not seen in FIG. 16A. The longitudinal support beams 1606 act as connectors to connect various portions of the roof system, wall system and ceiling panels of the ceiling system of the mobile unit 300, or other custom enclosure, together as described below. In addition, the longitudinal support beams 1606 may act as a seal and provide a sealing function to prevent fluids from moving between portions of the wall system, roof system and ceiling panels that are mounted to the longitudinal support beams 1606. A portion of these longitudinal support beams 1606 may also act as a ledge for at least some of the ceiling panels. The longitudinal support beams 1606 have a U-shaped channel.

[00255] It should be noted that the term wall system as used herein refers to an assembly of the various embodiments of the double-panel wall system or multi-panel wall systems described herein. Also, the term roof system as used herein refers to an assembly of roof panels such as those described herein or other roof panels. In addition, the term ceiling system as used herein refers to an assembly of ceiling panels. Furthermore, the term floor system as used herein refers to an assembly of floor panels and support members. Finally, the longitudinal support beams and alternative embodiments thereof described herein may be referred to as upper longitudinal support beams, caplets, rain caps or wall caps.

[00256] The longitudinal support beam 1606 may be used to connect the wall system (a portion of which is labelled as 1601) to the roof system 1600 of at least one embodiment of the mobile unit 300 or another custom enclosure. The longitudinal support beam 1606 may be made using powder coated painted aluminum or metal or another suitable material. For example, the longitudinal support beam 1606 may be made of marine grade aluminum or another material that provides sufficient strength and is not prone to corrosion. As shown in FIGS. 16B to 16D, each longitudinal support beam 1606 may comprise a single material compound piece that may be the length of several wall panels and in some cases may extend for about a third, a half or the entire length of the mobile unit 300 or other custom enclosure depending on the size of the mobile unit 300 or other custom enclosure. For example, the length of a given longitudinal support beam 1606 may range from about the combined length of two adjacent wall panels to about 16 feet but can be other dimensions in other embodiments.

[00257] In at least one embodiment, in which multiple longitudinal support beams 1606 are used for an entire double-panel wall section of one side of the mobile unit 300, the longitudinal support beams may be placed end to end such that end faces of adjacent longitudinal support beams may abut one another, may be closely spaced together or may have another element placed therebetween and are aligned along the length of the walls of the mobile unit 300 or other custom enclosure. In addition, the longitudinal support beams are arranged and dimensioned so that any seams between adjacent longitudinal support beams are preferably offset from any seams between adjacent wall panels used to make a double or multi-panel wall section of the mobile unit 300 or other custom enclosure. To provide for further strength and support, in at least one embodiment, the abutting ends of the longitudinal support beams may be releasably fastened together using appropriate connectors like plates that straddle and are attached, such as by bolts, screws, nails or other appropriate releasable fasteners, to the sides of the adjacent longitudinal support beams.

[00258] The longitudinal support beam 1606 comprises a channel 1606c having a width that is able to encompass at least a single panel wall, a two panel wall or three or more panel walls that are connected in a horizontally offset manner or are stacked opposite one another (e.g., sandwiched together) such as the double or multi-panel wall systems described herein, for example. The longitudinal support beam 1606 comprises a top surface 1608, a first side surface 1610 and a second side surface 1612. [00259] It should be noted that in an alternative embodiment, the channel 1606c may include another element, such as a vertical spacer 1608s shown in FIG. 17, between the underside of the top surface 1608 and the upper surface of the side wall(s) received therein which allows the height of the longitudinal support beam 1606 to be raised so that the roof system is angled when the longitudinal support beam 1606 on an opposing side wall is not at the same height. The use of a spacer and the height of the spacer may be determined to meet desired criteria for a custom enclosure depending on how the purpose of the custom enclosure and its external environment. In at least one embodiment, the spacer 1608s may be made using material that does not conduct heat very well in which case the spacer 1608s acts as a thermal break to provide heat insulation as described previously.

[00260] The top surface 1608 of the longitudinal support beam 1606 may be horizontal with respect to the top ends of the side surfaces 1610 and 1612 or it might be slightly angled in alternative embodiments which will result in roof panels that are slightly angled when they are releasably mounted to the top surface 1608. This allows a roof system to be angled to allow for run off of environmental elements such as rain, water and snow.

[00261] In at least one embodiment, as shown in FIGS. 16B-16E, the first side surface 1610 is positioned at the exterior of a custom enclosure during use and has a downward angled edge section 1611 (i.e., it is downward sloping) that acts to deflect away environmental elements, such as rain or snow, from the outer surface of the exterior wall panels. For example, the angled edge section 1611 may be referred to as a water or snow deflector that may redirect natural outdoor elements from entering the enclosure, thereby providing water or snow runoff. Alternatively, there may be embodiments that do not include the lateral segment 1611.

[00262] The second side surface 1612 has a lateral flange 1614 that acts as a shelf. The second side surface 1612 may be longer (e.g., have a greater height) than the first side surface 1610 so that one or more ceiling panels that sit on top of the shelf 1614 are spaced further apart from the roof panels of the roofing structure that is releasably connected to the longitudinal support beam 1606.

[00263] Referring now to FIG. 16E, shown therein is a perspective view of another example embodiment of a longitudinal support beam 1650 that is similar to the longitudinal support beam 1606 but is modified in a few ways. Other than these modifications, which are discussed in more detail below, the longitudinal support beams 1650 and 1606 operate similarly and engage the wall panel system, roof system and ceiling system in a similar way. Common elements for the longitudinal support beams 1600 and 1650 have the same reference numbers in the figures.

[00264] The longitudinal support beam 1650 is modified to provide a tray or trough 1615 which is formed by the shelf 1614, an upwardly directed wall 1652 that extends upward from the shelf 1614 and a lip or ledge 1654 that extends laterally outwards from an upper longitudinal edge of the wall 1652. The tray 1615 can be used to hold various components such as wires, cables, gas lines, other applicable infrastructure components or a combination thereof. For example, electrical cables and/or wires can sit within the tray 1615 and then be routed to another room such as an electrical room or a maintenance room. In this example embodiment, the wall 1652 is angled but in alternative embodiments it might be a straight vertical wall.

[00265] In at least one embodiment, the longitudinal support beam 1650 may also incorporate slots or holes 1656, only one of which is labelled for simplicity, to allow for components such as wires, gas lines, cables or other infrastructure components, for example, to be passed between at least one of the cavities of the wall panel system and the tray 1615 without leaving these components exposed to the interior of the custom enclosure where they may be damaged or may cause other problems. For example, cables may be passed between the interior of the double-wall panel system 1601 and the tray 1615 in which case the tray 1615 may be referred to as a cable tray.

[00266] The slots 1656 are large enough such that a worker can drill a hole into an interior wall panel using one of the slots 1615 as a template and then pass the infrastructure components therethrough. For example, the worker who is drilling holes into the interior wall panel may be drilling on an angle to allow for more access for drilling the hole itself and passing cables through one or more of the slots 1656.

[00267] In at least one embodiment, the longitudinal support beam 1650 may also include smaller apertures through which screws may be inserted to releasably fasten the longitudinal support beam 1650 to the interior wall panels. There may be similar apertures on the side wall 1610 for releasably fastening the opposite side of the longitudinal support beam 1650 to the outer surface of the exterior wall panels.

[00268] These embodiments of the longitudinal support beam 1650 may be used with a ceiling structure that is a drop ceiling in which edges of the ceiling panels closest to the walls of the custom enclosure sit on top of the ledge 1654. This may also be referred to as a false ceiling. Any cables or electrical wiring can then be run from the tray 1615 along the top surface of the ceiling panels to an electrical fixture such as a light, for example. A false ceiling may be suitable for custom enclosures that are used for medical purposes such as a patient room, an ICU, an operating room or other healthcare structure.

[00269] Referring now to FIG. 17, there is shown an enlarged view of the connection 1700 between a portion of a roof system 1703 and a portion of a wall system 1702 using the longitudinal support beam 1606. It should be noted that insulation may be used but is not shown in FIG. 17. An example of the use of insulation is shown in FIG. 24M for another embodiment. The longitudinal support beam 1606 may be placed such that the bottom side of the top section 1608 (i.e., top surface) is resting on top of a spacer 1705, as described earlier to adjust the height of the longitudinal support beam 1606. In an alternative embodiment, the longitudinal support beam 1606 may be placed such that the bottom side of the top section 1608 sits on the top surface of several interior and exterior wall panels including wall panels 1704 and 1706 of the wall system 1702. The longitudinal support beam 1606 may be placed such that the longitudinal support beam 1606 provides additional support to hold the wall panels 1704 and 1706 adjacent to one another as well as the wall panels 1704 and 1706 being releasably coupled to one another in a coplanar fashion. The longitudinal support beam 1606 is placed over the exterior wall panel 1704 and the interior wall panel 1706 so as to cover the seam created by the abutment of the two adjacent exterior and interior wall panels, the seam created by the abutment of adjacent interior wall panels, and/or the seam created by the abutment of adjacent exterior wall panels. The longitudinal support beam 1606 may provide a structural support for the wall panels 1704 and 1706 to keep them upright and together. The longitudinal support beam 1606 may provide further support for extra loading that may be transferred to the mobile unit 300 or custom enclosure, which may be due to various factors such as wind loads, snow loads, dead loads, and/or live loads.

[00270] While the longitudinal support beam 1606 is shown covering a portion of a double wall panel system, in other embodiments the width of the channel 1606c of the longitudinal support beam 1606 can be selected to receive a single-panel wall or to receive three or more wall panels for a multipanel wall system such as that shown in FIG. 14G as an example.

[00271] Referring again to FIG. 17, the first side 1610 of the longitudinal support beam 1606 extends away from the top surface 1608 downwards along the outside of the exterior wall panel 1704. The second side 1612 of the longitudinal support beam 1606 extends downwards away from the top surface 1608 along the inner surface of the interior wall panel 1706. One or more roof panels 1714 are placed on top of section 1608 of the longitudinal support beam 1606. The length of the second side 1612 may be longer than that of the first side 1610 of the longitudinal support beam 1702 as is shown in FIG. 17 to provide a space 1718 (e.g., referred to as ceiling cavity or a roof cavity) between the ceiling panels and the roof panels. The second side 1612 further comprises the lateral shelf 1614 extending laterally outwards from a lower portion of the second side 1612 and may be used for supporting a portion of one or more ceiling panels 1716 of the ceiling system. The distance between the upper surface 1608 and the lateral shelf 1614 of the longitudinal beam (which may also be referred to as a single piece trim 1606) can be increased to provide a greater height for the space 1718 between the roof structure 1703 and the ceiling panels.

[00272] As described previously, multiple longitudinal support beams 1606 may be placed in an end-to-end manner to abut against one another along the top surface of the wall panel system 1702 to provide support for the wall system 1702 and the roof system 1703 along a portion of or the entire circumference of the mobile unit 300 or other custom enclosure. The wall panels of the wall panel system 1702 may also be secured to the longitudinal support beam 1606 through any releasable securing means such as, but not limited to, fasteners like screws, bolts, or any other connection means, for example, although preferably releasable connection means are used.

[00273] In use, the longitudinal support beam 1606 may be used to provide support for one or more roof panels 1714. The roof panels 1714 may sit on top of the top section 1608 of the longitudinal support beam 1606. The roof panels 1714 may also be secured to the longitudinal support beam 1606 through any releasable securing means such as, but not limited to, fasteners like screws, bolts, or any other connection means, although preferably releasable connection means are used, for example. In other embodiments, other types of roof panels may be used and the roof system may be flat, sloped or partially sloped (e.g., see FIG. 24M).

[00274] In at least one embodiment, the construction of the longitudinal support beam 1606 may allow the mobile unit 300 or other custom enclosure to be constructed in such a way as to allow the ceiling panels 1716 to be releasably installed onto the lateral shelf 1614 first, through any releasable securing means, such as, but not limited to, releasable fasteners like screws, bolts or any other suitable releasable connection means, for example. In other embodiments, other types of ceiling panels/tiles may be used.

[00275] Once the ceiling panels 1716 have been installed on the lateral shelf 1614, functional components such as electrical necessities (e.g., electrical wires, etc.), piping for water, air or another gas, communication cables or wires, insulation, HVAC systems, electrical devices including, but not limited to, sound measuring and pressure control devices, or any other functional/infrastructure components needed for use within the mobile unit 300 may be installed within the cavity 1718 between the roof panels 1714 and the ceiling panels 1716. The inclusion of this cavity may allow for ease of construction, as the initial installation of the ceiling panels 1716 may allow for work to be conducted later within the mobile unit 300 or custom enclosure before the roof panels 1714 and the functional components are being installed above the ceiling panels 1716.

[00276] Referring now to FIG. 18, shown therein is a perspective view of the connection 1700 between a roof system 1802 and the wall system 1702. The longitudinal support beam 1606 is shown underneath the roof panels 1804a and 1804b and encompassing the wall panels 1704 and 1706, as described in FIG. 17. Shown in further detail in FIG. 18 is the connection between two roof panels 1804a and 1804b, wherein the lateral portion 1808 of the first roof panel 1804a encompasses the entirety of the lateral portion 1810 of the adjacent second roof panel 1804b, as was discussed in FIGS. 15A-15C. Further shown in detail in FIG. 18 is a releasable connection between the lateral shelf 1614 of the longitudinal support beam 1606 and the ceiling panels 1716, which may be made using a releasable fastener 1806, for example. It should be noted that insulation may be used but is not shown in FIG. 18. Also, in other embodiments, different roof panels and/or different ceiling panels may be used. Further, thermal breaks can be used, similarto spacer 1608s (that has thermal insulative properties), between the top of the wall panels and the bottom the longitudinal support members 1606.

[00277] Referring now to FIGS. 19A-19B, shown therein are two perspective front views of an alternative embodiment of a roof panel 1900 with a basket 1920 at a lower portion thereof in accordance with the teachings herein. The upper portion of the roof panel 1900 is similar to the roof panel 1500. Accordingly, the roof panel 1900 comprises a roof section 1901 having a bottom surface 1902 and an upper surface 1904, as well as a first side section 1906 having a side surface 1911 and a second side section 1908 having a side surface 1913 that both extend away from the upper surface 1904 of the roof section 1901. The first side section 1906 comprises a first connecting component having a first lateral portion 1910. The second side section 1908 comprises a second connecting component having a second lateral portion 1912. The second lateral portion 1912 may be slightly smaller in length than the first lateral portion 1910. The first connecting component further has a first transverse extent 1914 extending from the first lateral portion 1910 so that the first connecting component forms a channel 1910c. The roof panel 1900 may generally have a width between about 16 and about 24 inches and a length between about 96 and about 144 inches. Alternatively, for certain applications in which the mobile unit 300 or other custom enclosure is smaller or larger, the roof panel 1900 may have other dimensions.

[00278] The basket 1920, which may also be referred to as a shelf, of the roof panel 1900 has a lower panel section 1921 with two upward oriented side walls 1922 and 1924 that extend therefrom. The basket 1920 may be U-shaped as shown. The side walls 1922 and 1924 may be releasably connected to the side surfaces 1913 and 1911 , respectively, of the roof panel 1900 such that there is a space or cavity between an upper surface of the basket panel section 1921 and the lower surface 1904 of the roof section 1901 . This cavity may be used to receive certain components.

[00279] In at least one embodiment, the basket 1920 may also include a plurality of apertures 1928 that may be situated on any combination of the section 1921 , the side wall 1922 and/or the side wall 1924. The apertures provide for sound attenuation when the roof panels 1900 are used for a custom enclosure that includes sound generating sources that create loud noise such as, but not limited to, an engine for example and it is desired that the generated loud noise is acoustically attenuated so that it is not as audible outside of the custom enclosure. Accordingly, when there are components in a custom enclosure that are excessively noisy, the roof panels 1900 may be used for the roof system of the enclosure to dampen the sound that is generated from within so that the sound is not as audible outside of the enclosure. [00280] The apertures 1928 may have various shapes, patterns and/or sizes. For example, the apertures 1928 may have a shape that includes, but is not limited to, circular, elliptical/oblong, rectangular, square, polygonal (e.g., pentagonal, hexagonal, etc.) or a cross. The apertures may have a diameter or width of about 1 inch, but other sizes can be used in other embodiments. The sheet having the apertures 1928 acts as a membrane to return sound waves back to the sound generating source for at least partial cancellation of other sound waves emanating from the sound generating device.

[00281] Referring now to FIG. 19C, shown therein is an exploded perspective front view of an alternative embodiment of a roof panel 1950 that is structurally similar to the roof panel 1900 of FIGS. 19A-19B and also includes an insulation block 1952. The insulation block 1952 is meant primarily for use in acoustic insulation but may also provide some amount of thermal insulation. The insulation block 1952 may be placed within the cavity of the basket 1950 to provide an additional amount of acoustic insulation to the acoustic dampening that is provided by the apertures 1928. The insulation block 1952 may be made from any insulation material that provides a desired amount of insulation. For example, the insulation material may be a rock wool, a slag wool, cellulose, foam board or spray foam material. For example, the insulation material may be RoxlIL insulation that provides sound attenuation and also fire resistance.

[00282] Accordingly, in at least one embodiment, a custom enclosure may be built with a roof system that incorporates a plurality of roof panels such as roof panels 1950. The roof panels 1950 may be releasably connected to the custom enclosure and the custom enclosure may be used to house large engines or other noisy or large equipment. In conventional enclosures that use conventional roof structures, when such engines have to be serviced and some engine pieces replaced, one or more sections of such conventional enclosures have to be cut and removed in order to access the engine. However, in embodiments which utilize the roof panels described herein, a section of the roof panels or a larger percentage (e.g., 50%, 75% or near 100%) of the roof panels may be easily disassembled, since they were initially releasably connected, and the engine or other large equipment can then be removed or accessed from the top of the enclosure where the roof panels were disassembled. Alternatively, in custom enclosures which utilize the releasably connectable double-panel wall system described herein, a section of the wall panels may be easily disassembled, since they were initially releasably connected during initial assembly, and the engine can then be removed or accessed from the section of the wall panels that were disassembled.

[00283] Referring now to FIGS. 20A and 20B, shown therein are upper and lower perspective views of a connection between an alternative embodiment of the roof system of FIGS. 19A-19C, an alternative embodiment of the longitudinal support beam 1650 and the wall system 1601 of FIG. 17. In this case, roof panels 2000 are similar to roof panels 1900 except that the roof panels 2000 have truncated basket portions 1920a so that the far edge of the basket 1920a does not extend to the edge of the roof panels but instead abuts against the side wall 1612 of the longitudinal support beam 2002. Also, the upper portion of the far edge of the roof panel 2000 extends past the basket 1920a such that it rests upon the surface 1608 of the longitudinal support beam 2002. Releasable fasteners may be used to secure the far edge of the roof panel 2000 to the upper surface 1608 of the longitudinal support beam 2002. The longitudinal support beam 2002 is a modified version of longitudinal support beam 1650 in that the height of the side wall 1612 has been increased and/or the height of the upward wall 1652a has been reduced so that the ledge 1654 is not flush with the upper surface 1608 but rather flush with the lower surface of the basket 1920a of the roof panel 2000. Releasable fasteners may also be applied to releasably secure the ledge 1654 to the lower surface of the basket 1920a.

[00284] In at least one embodiment, the roof panel 2000 may be further modified so that the lower surfaces at the far end of the basket 1920a includes slots 2004 (see FIG. 20B) which allow cables, wires, gas lines or other components to be passed from an interior of the double wall panel 1601 to the tray 1615 and then through one of the slots 2004 into the basket 1920a. In such cases the baskets 1920s may be empty. These components can then be run to another region of the enclosure or to another room such as a maintenance room or an electrical room where the electrical wires may be attached to a distribution panel, for example.

[00285] It should be noted that while FIGS. 20A and 20B show a doublepanel wall system, the longitudinal support beam 2002 can be used with a single panel wall system or a multi-panel wall system with three or more horizontally offset wall panels by varying the distance between the side walls 1610 and 1612 thereby varying the size of the channel 1606c.

[00286] It should be noted that in various embodiments of custom enclosures using the wall and roof panels described herein, the longitudinal support beam which may be used depends on the circumstances and may be the longitudinal support beam 1606 without the tray or one of the longitudinal support beams 1660 or 2002 with the tray.

[00287] Referring now to FIG. 21 A, shown therein is a perspective view of several components of a custom enclosure 2100 including a double panel wall system, and a floor system 2104 in accordance with the teachings herein. The double panel wall system includes double-panel walls 2102a, 2102b and 2102c. Corner support members may be used to provide additional structural support where different double panel walls meet such as corner support member 2103o which helps to releasably secure the double panel walls 2102a and 1202b together. FIG. 211 shows a top view of the corner support member 2103o in more detail.

[00288] FIG. 21 A shows that the floor system 2100 includes longitudinal support beams 2108a-2108d that run along the length of the enclosure 2100 and cross members (i.e. , floor cross beams), only four of which are labelled, for ease of illustration, as 2106a-2106d, that run side to side and may be perpendicular to the longitudinal side beams 2108a and 2108d. The floor system 2100 also includes a plurality of floor panels that are installed on top of the floor cross beams. One example of a floor panel 2105 is shown for simplicity in FIG. 21A. Some of the longitudinal support beams 2108a-2108d, e.g., beams 2108a and 2108d, may be used to releasably couple the double panel walls 2102a-2102c to the floor system 2104 (the support beam for the rear double panel wall 2102b cannot be seen).

[00289] The components of the floor system 2104 may be made using structural steel which is more heavy-duty. Other materials that may be used for the floor system 210 include, but are not limited to, wood joists, engineered wood (e.g., engineered laminate veneer lumber), composite materials which may include carbon thermoplastics or 3D printed materials, for example. The longitudinal support beams 2108a-2108d may be referred to as floor longitudinal support beams, lower longitudinal support beams or C-shaped support beams (for the example shown).

[00290] For custom enclosures that are larger in width, such as the enclosure 2100, some of the longitudinal support beams 2108a-2108d, e.g. , beams 2108b and 2108c, may be used to releasably couple different sections of the floor system 2104 together. Accordingly, some of the cross beams including floor cross beams 2106a and 2106c are used to form a first section of the floor system 2104 and other cross beams including floor cross beams 2106b and 2106d are used to form a second section of the floor system 2104. Accordingly, in this case, the longitudinal support beams 2108b-2108c are coupled to one another and to the first and second floor sections, respectively. For example, the longitudinal support beams 2108b and 2108c may be oriented back-to- back, which may also be referred to as side-by-side (e.g., in a mirrored arrangement) so that the vertical sections of these beams are adjacent to one another.

[00291] Since the enclosure 2100 is a double-width enclosure that provides the same space as two rooms side-by-side but without a wall situated near the middle section of the enclosure 2100, several posts 2114 and a roof support structure 2112 may be used to support the ceiling system and the roof system which are both not shown. Only one of the posts 2114 is labeled for simplicity of illustration. The enclosure 2100 may also be referred to as a double-room enclosure. [00292] Referring now to FIGS. 21 B-21C, shown therein are side and perspective views, respectively, of a portion of a side wall 2102a with a longitudinal connection member 2120 for providing connection between the side wall 2102a and the longitudinal support beam 2108a of the floor system 2104 in accordance with the teachings herein. The longitudinal connection member 2120 may also be referred to as a Z channel beam. Although not shown, depending on the length of the side wall 2102a and the length of the longitudinal connection member 2120 there are typically several longitudinal connection members 2120 that are arranged sequentially to substantially or totally cover the length of the side wall 2102a. The longitudinal connection member 2120 generally comprises a middle horizontal section 2120b that has a first edge that extends into an outer downward vertical section 2120c and an opposing second edge that extends into an upward vertical section 2120a. The middle horizontal section 2120b is releasably coupled to a top portion of the longitudinal support beam 2108a via one or more releasable fasteners such as bolts or screws, for example. The outer downward vertical section 2120c is releasably coupled to the panel extension 1203 of exterior wall panels such as exterior wall panel 2102ao of double panel side wall 2102a using one or more releasable fasteners such as bolts or screws, for example. The inner upward vertical section 2120a slidably receives the comprise slotted end portions 1120 and 1122 (not shown) of an interior wall panel and one or more releasable fasteners such as screws or bolts may be used to releasably couple the upward vertical section 2120a to the lower portion 1103 of an interior wall panel such as interior wall panel 2102ai of double panel side wall 2102a. In alternative embodiments, such as for permanent enclosures, any of the releasable couplings described herein may be replaced with more permanent connections such as welds, for example.

[00293] Referring now to FIGS. 21 D-21 E, shown therein are perspective partial exploded views of the outer and inner surfaces of a portion of the side wall 2102a along with the longitudinal connection member2108a of FIGS. 21 B- 21C and a portion of the floor system of FIG. 21 A. The longitudinal connection members 2120 are first attached to the longitudinal support beams 2108a. Several longitudinal connection members 2120 and 2121 are shown attached in an abutting fashion to one another (there may be more than two longitudinal connection members that are used depending on the length of these members and the lengths of the side wall 2102a).

[00294] The floor cross beams 2106a and 2106c, only two of which are labelled for simplicity, are releasably connected to the longitudinal support members, which in this case are longitudinal support members 2108a and 2108b, which may be done using releasable fasteners such as bolts, for example. The floor system 2104 may be assembled so that the left and right floor sections are assembled separately. In the case of a single room width enclosure, there is only one floor section that is assembled. For the assembly of each floor section, once both ends of the cross members are releasably connected to the longitudinal support beams, a plurality of floor panels (where floor panel 2105 in FIG. 21 A is shown as an example) may be placed on top of the plurality of cross beams.

[00295] It should be noted that when assembling the floor system 2104, in addition to installing floor panels, other functional elements can be installed in the floor system related to the construction/operation of the custom enclosure. These functional elements may include mechanical floor access panels that allow access to the space under the floor, water supply pipes and drainage pipes, floor electrical access ports and any other floor entry points as needed.

[00296] Once the floor sections of the floor system 2104 are assembled, the longitudinal connection members 2120 and 2121 are attached to one or more longitudinal support beams 2108a, and the interior wall panels are releasably connected to the upward vertical sections 2102a of the longitudinal connection members 2120 and 2120a. Adjacent interior wall panels are also releasably connected to one another as previously described. After the various inner wall components (e.g., mechanical, electrical, and/or structural elements) have been added to the outer surface of the interior wall panels, the exterior wall panels can be releasably connected to opposing interior wall panels while also engaging adjacent exterior wall panels. The lower panel extension 1203 of the exterior wall panels are also releasably connected to the outer downward vertical sections 2120c of the various longitudinal connection members 2120 and 2120a. It should be noted that in at least one alternative embodiment, thermal spacers may be used, such as thermal spacer 2120s, to reduce heat transfer between the components of the floor system and the wall system. Depending on the application of the custom enclosure, the thermal spacers 2120s may be optional. A plurality of the thermal spacers 2120s may be used and they may have different shapes compared to what is shown in FIG. 21 D.

[00297] The assembly and attachment of the double-panel wall 2102a and a first half (e.g., left half) of the interior and exterior wall panels for side wall 2102b may be done to complete the left half of the outer shell for the enclosure 2100. Certain interior components for the first half (e.g., left half) of the enclosure 2100 may then be installed/assembled. The assembly and attachment of the double-panel walls 2102a and the second half (e.g., right half) of the interior and exterior wall panels for side wall 2102b may then be done (or done in parallel with the assembly of the left half) to complete the right half of the outer shell for the enclosure 2100. Certain interior components for the second half (e.g., right half) of the enclosure 2100 may then be installed/assembled. In this fashion two halves of the double-room enclosure 2100 may first be constructed and then transported separately to the installation site where they are assembled together.

[00298] Referring now to FIG. 21 F, shown therein is a perspective view of a portion of a roof support structure 2112 that may be used with the double-room enclosure 2100 of FIG. 21 A in accordance with the teachings herein. The roof support structure 2112 may be used for enclosures that are at least doubleroom enclosures where there may be portions of the walls missing/not used, near the mid-portion of the enclosure 2100. The roof support structure 2112 includes first and second roof support beams 2130 and 2132, first support brackets 2134a-2134b and second support brackets 2136a-2136b, and connectors 2140 and 2142. [00299] Although just two roof support beams 2130-2132 are shown, there are generally one or more additional roof support beams that are arranged linearly such as in an end-to-end configuration with roof support means 2130 and 2132 to span all of the length of the enclosure 2100. The roof support beams 2130 and 2132 may be hollow (as shown) or may be solid in other embodiments. The roof support beams 2130 and 2132 may have a rectangular cross-section, an I-beam cross-section or another suitable cross-section. The roof support beams 2130-2132 may be made from steel, aluminum, any other suitable metals, composite materials or other materials. The roof support beams 2130-2132 may be releasably bolted in place or welded depending on the use of the custom enclosure 2100.

[00300] Although only two first support brackets 2134a-2134b and two second support brackets 2136a-2136b are shown, it should be understood that there may be additional ceiling support brackets that are arranged linearly such as in an end to end manner to span the entire length of the enclosure 2100 or spaced apart to span a substantial portion (e.g., more than 75%) of the length of the enclosure 2100. The support brackets 2134a-2134b and 2136a-2136b have a vertical section for releasable mounting to the longitudinal support beams 2130 and 2132, respectively, using releasable fasteners such as bolts, for example, or permanent fastening such as welds in some cases. The support brackets 2134a-2134b and 2136a-2136b may have an upper flange or generally upper horizontal portion that extends from a top portion of the vertical section to provide structural support for at least a portion of the roof system (not shown). The support brackets 2134a-2134b and 2136a-2136b may also have a lower flange or generally lower horizontal portion that extends from a bottom portion of the vertical section to provide structural support for at least a portion of the ceiling system (not shown). The support brackets 2134a-2134b and 2136a-2136b may be made from a similar material as the roof support beams 2130-2132 such as steel, aluminum, composite materials or other suitable materials. [00301] The connectors 2140 and 2142 may be used to releasably connect to an upper portion of support posts, such as support post 2144, which provide some load bearing support for the ceiling system and/or roof system. As shown in FIG. 21 A, the lower portion of the support posts may be releasably coupled to the longitudinal floor support beams 2108b and 2108c. In addition, a forward- most portion of the roof support system 2112 may be releasably coupled to a front wall while the rearward most position of the roof support system 2112 may be releasably coupled to a portion of the rear side wall 210b using releasable fasteners such as bolts for example.

[00302] Referring now to FIG. 21 G, shown therein is a cross-sectional view of a portion of a ceiling system 2150 and a roof system 2160 that may be used with the wall system of the double-room enclosure 2100 of FIG. 21 A or another custom enclosure in accordance with the teachings herein. Insulation may be used but is not shown in FIG. 21 G. The floor system 2104 is not shown and the first and third walls 2102a and 2102c are shown along with longitudinal support beam 1606a and 1606b which are similar to the longitudinal support beam 1606. The ceiling system 2150 comprises a plurality of right section ceiling panels 2152 and left section ceiling panels 2154. The roof system 2160 comprises a plurality of right section roof panels 2162 and left section roof panels 2164 along with a roof crown or roof caplet 2166. It should be understood that there may be a plurality of longitudinal support members 1606a and 1606b, a plurality of roof support beams 2130 and 2132, a plurality of support brackets 2134a and 2134b, a plurality of roof panels 2162 and 2164 and a plurality of roof caplets 2166 that span all or a substantial portion of the length of the enclosure 2100. The roof caplet 2166 may extend for at least about 1 foot, for example, and is used to cover two half-roofs so as to provide a sealing function from the environmental elements. In at least one embodiment, the enclosure 2100 may also include vertical support posts 2165a and 2165b (which are optional and shown with dotted lines) that are releasably connected to the roof support beams 2130 and 2132, respectively. [00303] One side edge of the plurality of right section ceiling panels 2152 rests on the lower flange portion of the support bracket 2134b and the other side edge of the plurality of right section ceiling panels 2152 rests on the lower flange portion of the longitudinal support beam 1606b. Likewise one side edge of the plurality of left section ceiling panels 2154 rests on the lower flange portion of the support bracket 2134a and the other side edge of the plurality of right section ceiling panels 2154 rests on the lower flange portion of the longitudinal support beam 1606a. The ceiling panels 2152 and 2154 may generally be releasably connected to the brackets 2134a and 2134b and the longitudinal support beams 1606a and 1606b using releasable fasteners such as bolts or screws, for example. After the ceiling panels 2152 and 2154 are assembled, a sealant can be applied to the seams to provide an airtight seal if the enclosure 2100 is being used in a medical or laboratory setting or other applications where air quality and air pressure in the enclosure 2100 is important.

[00304] One side edge of the plurality of right section roof panels 2152 rests on the top surface of upper horizontal flange of the support bracket 2134b and the other side edge of the plurality of right section ceiling panels 2152 rests on an upper surface of the longitudinal support beam 1606b. Likewise one side edge of the plurality of left section roof panels 2164 rests on the top surface of the upper horizontal flange portion of the support bracket 2134a and the other side edge of the plurality of right section roof panels 2164 rests on the upper surface of the longitudinal support beam 1606a. The roof panels 2162 and 2164 may generally be releasably connected to the brackets 2134a and 2134b and the longitudinal support beams 1606a and 1606b using releasable fasteners such as bolts or screws. After the roof panels 2162 and 2164 are assembled, roof caplets 2166 may be releasably connected at the midpoint of the roof system 2160 along all or substantially (e.g., at least 75%) all of the length of the enclosure 2100 to provide further structural integrity to the roof system 2160. Once the elements of the roof system 2160 are assembled, a sealant can be applied to any seams to provide a watertight seal if the enclosure 2100 is exposed to the elements. [00305] In an alternative embodiment, there may be an alternative implementation of the roof system that is used in which one or more trusses are used to provide support for the roof panels. An example of a roof system that uses one or more trusses is shown in PCT patent application no. PCT/CA2021/051323 filed on Sept. 23, 2021 , which is herein incorporated by reference.

[00306] The roof system 2160 may also have a releasably coupled configuration which allows each half of the custom enclosure 2100 to be manufactured and then releasably connected together during installation by releasably connecting certain structures together including the left and right sections of the roof system 2160. For example, this may include releasably connecting the roof support beams 2130-2132 to one another. This may be done using releasable fasteners and sealing material, examples of which are discussed with respect to FIG. 21 H.

[00307] Referring now to FIG. 21 H, shown therein is a magnified cross- sectional view of a portion of an example embodiment of a releasable connection between two units that may be releasably joined together to create part or all of a roof structure 2160a for a larger custom enclosure. One of the units has a first roof structure and the other unit has a second roof structure. Similar reference numerals are used for similar elements in FIGS. 21 G and 21 H. The roof caplet is not shown in FIG. 21 H but may be used to cover the region where both roof structures meet or are closest to one another. The first and second roof structures together include first and second sets of roof panels 2162a and 2162b that have truncated baskets 2164a and 2164b and first and second sets of upper longitudinal support members 2002a and 2002b that are mounted to first and second sets of support beams 2132 and 2130, respectively, such that the top of the sets of support beams 2130 and 2132, respectively, are received within the channels of members 2002b and 2002a to provide a structural connection to the roof panels. The roof panels 21262a and 2162b, the truncated roof baskets 2164a and 2164b and the longitudinal support members 2002a and 2002b have a somewhat similar structure to the example shown in FIGS. 20A-20B. A releasable connection system is adapted to releasably connect the first and second sets of roof support beams adjacent to one another to form a combined roof system structure from the releasable connection of the first and second units.

[00308] The roof structure 2160a may be referred to as a releasably connectable split roof since the two custom enclosure units may be assembled independently, delivered to a site and then releasably connected to one another during site installation of the full custom enclosure. The releasable connection system comprises a plurality of bolts that are removably inserted along a length of the first and second sets of longitudinal roof support members. An example of a bolted flange releasable connection is shown at 2167. The releasable connection system may be used instead of welding (which is conventionally used). This releasable connectivity is advantageous in that the custom enclosure may be disassembled if needed and transported to another site where it may be re-assembled, which is not possible if welding were used. In at least one embodiment there may be a plurality of bolts that are spaced out along the extent of the longitudinal support beams 2130 and 2132 to provide for a more secure coupling.

[00309] Also, in between the bolted flange connections along the lengths of the longitudinal support members 2130 and 2132 may be sealing material 2168 which is used to prevent any water, rain, snow or other environmental elements from entering into the enclosure. The sealing material 2168 may be made from neoprene foam, closed cell foam or other suitable sealing materials.

[00310] During installation, the sealing material is placed between facing surfaces of the first and second sets of longitudinal roof support members before the releasable connection system is applied which results in the two units including the two half roof structures being mechanically pulled or other urged together with the sealing foam material in place. Application of the releasable connection system, which may be done using a stud assembly, applies a compressive force to the sealing material to improve its sealing properties. As the support beams 2130 and 2132 are pulled closer together and releasably secured together, this compresses the sealing form 2168 to form a leak proof seal to reduce any occurrence of leaks in the releasably connectable roof structure.

[00311] Referring now to FIGS. 211 and 21 J, shown therein are top cross- sectional and top perspective views, respectively, of a portion of a corner of the custom enclosure 2100 of FIG. 21 A showing how at least one corner support member 2103o may be used to provide additional structural support where the double panel walls 2102a and 2102b meet one another. In this example, there is the outer corner support member 2103o and an inner corner support member 2103i which may both be releasably secured to outer and inner surfaces, respectively, of the double panel walls 2102a and 1202b using releasable fasteners, such as bolts for example.

[00312] The corner support members 2103o and 2103i may be implemented using L beams or L-brackets with two sections or arms 2103oa, 2103ob and 2103ia, 2103ib, respectively, that each have lengths that are sufficient to provide a desired amount of structural support. The lengths of these sections 2103oa, 2103ob, 2103ia, 2103ib may be different than what is shown in FIG. 211 in other embodiments. For example, these sections 2103oa, 2103ob, 2103ia, 2103ib do not all have to have the same lengths and the section 2103ob may be made longer to provide more structural support in some cases. The corner support members 2103o and 2103i may be made of steel or another material that can provide a desired amount of rigidity but also flex when the custom enclosure experiences temporary forces due to wind or explosions, for example. The corner support members 2103o and 2103i may also be made using material having certain properties, such as being fire retardant or anticorrosive, or may have a coating with these properties.

[00313] The corner support members 2103o and 2103i may be referred to as corner support trim and may have a height that substantially extends from a top end portion of the double-panel walls 2102a and 2102b near, adjacent or overlying the longitudinal support members (also known as the wall caps) to a bottom end portion of the double-panel walls 2102a and 2102b near, adjacent or overlying the lower longitudinal support members at the floor system. Alternatively, in other embodiments, the corner support members 2103o and 2103i may have shorter lengths such that they cover about 50% to about 95% of the height of the walls 2102a and 2102b.

[00314] In FIG. 21 J, it is noted that an alternative embodiment of a roof panel 1500a is shown in which the outermost edge does not have an upper straight wall such as the side wall 1511 but rather has a downward angled side wall 1511a which aids with deflecting the environmental elements away from the outer surfaces of the exterior wall panels of the custom enclosure similar to the downward angled edges 1611a and 1611 b of the wall caps in that region.

[00315] Referring now to FIG. 22A, shown therein is an upper perspective view of a laboratory 2200 (with the roof system removed) that may be constructed using the construction techniques and one or more embodiments described herein for the double-panel wall system, the floor system and/or the roof system. The laboratory 2200 has a modular layout in that the laboratory 2200 comprises a series of similar laboratory units 2202, 2204, 2206 and 2208 assembled side by side. In addition, each laboratory unit comprises half units that are joined together. For example, the laboratory unit 2202 comprises half units 2202a and 2202b joined at seam 2202s, the laboratory unit 2204 comprises half units 2204a and 2204b joined at seam 2204s, the laboratory unit 2206 comprises half units 2206a and 2206b joined at seam 2206s and the laboratory unit 2208 comprises half units 2208a and 2208b joined at seam 2208s.

[00316] Each of the half units may be mostly (e.g., 95%) orfully pre-fabricated and tested at a manufacturing location and then transported separately to the site and assembled together at the installation site. This allows for a reduction in time for installing the laboratory at the installation site. Furthermore, since the laboratory half units 2202a-2208b are releasably connected to one another during assembly at the installation site, the laboratory half units 2202a-2208b can be easily disassembled and then transported to another site and assembled once more. In at least one embodiment, each half unit may have dimensions to allow them to be transported on a transport truck. In such cases, each half unit may have a dimension that is similar to an intermodal shipping container although each half-unit is a part of a custom enclosure.

[00317] One or more of the laboratory units 2202-2208 may have an air handling system that is accessible through a maintenance room. In this case each of the laboratory units 2202-2208 have their own respective air handling system accessible by their own respective maintenance rooms 2202m-2208m, respectively. This allows each laboratory unit 2202-2208 to maintain its own respective air pressure and air conditioning levels independent of the other laboratory units. Accordingly, each of the laboratory units 2202-2208 may operate independently from one another. The maintenance rooms 2202m- 2208m for each laboratory unit 2202-2208 house electrical and HVAC components and can be accessed from the exterior which significantly reduces the number of times that service personnel ever have to enter into the laboratory units 2202-2208. In at least one embodiment, each laboratory unit 2202-2208 may also have their own UPS system in case of power failure. The air handling system, as described in PCT patent application no. PCT/CA2021/051031 filed on July 23, 2021 , allows the laboratory units 2202- 2208 to independently operate in different pressure environments including negative pressure environments.

[00318] Referring now to FIG. 22B, shown therein is a top perspective magnified view of a portion of the laboratory 2200 of FIG. 22A. In particular, the lab unit 2206 is shown comprising half units 2206a and 2206b that are connected along seam 2206s. The seams 2206s are joints between the half units which may be covered using cover plates, for example. Each of the half units 2206a and 2206b may be constructed to utilize different structures and have different functions. For example, the half unit 2206 may be provided with doors that allow entry into a common space 2210 which is separated by a door and a double-panel cross wall from an anteroom 2214 which may also function as a changing room. The anteroom 2214 itself is separated by another doublepanel cross wall and door from a laboratory workspace 2218b. The anteroom 2214 may be kept at negative pressure relative to the entrance area (on the south side of the anteroom 2214 according to the layout in FIGS. 22A and 22B). The laboratory workspace 2218b includes various workspaces 2220b including desks and cabinets and a fume hood 2222b. The laboratory workspace 2218 may also be maintained at a negative pressure with respect to the anteroom 2214 or other rooms in the structure 2200. In contrast, the half unit 2206a includes a workspace 2212 which may have a desk and chairs. The workspace 2212 is separated by a double-panel cross wall and a door that leads into a lavatory 2216 with a sink and another cross wall and door that leads to a toilet. The lavatory 2216 is separated by another double-panel cross wall from a larger laboratory workspace 2218a that includes various workspaces 2220a including desks and cabinets and a fume hood 2222a.

[00319] It should be noted that any openings near an end of a given wall that do not have a hung door may be capped with a trim piece to hide the interface components of the wall panels that make up the given wall. In addition, any inner corners between wall panels may include a corner support member such as corner support member 2103i, for example, where structural support is needed or a trim piece can be used for finishing purposes at areas of the structure where there are internal corners, at the ends of internal walls such as the end of wall 2332 that faces the inside of the of the laboratory workplace (see FIG. 22B) and also for support posts such as support posts 2226. The trim piece may be made using HSS tubing, for example. For some cases, flashing kits may also be used where needed for weatherproofing. In some cases, mechanical fasteners or angled clips can be used.

[00320] As can be seen in FIG. 22B, the laboratory workspaces 2218a and 2218b are not separated by sidewalls so that they are joined to provide a larger workspace. A support post 2226 may be used along with a roof support system (not shown) similar to that described for custom enclosure 2100. Alternatively, a truss system, such as one of the truss systems described in PCT patent application no. PCT/CA2021/051323 filed on Sept. 23, 2021 , may be used to provide roof support for this open area of the laboratory unit 2206. To further provide for structural integrity and also allow for the modular construction of the full laboratory 2200, double-panel side walls 2228 and 2230 may run the length of each half unit 2206a and 2206b, respectively. In addition, outer and inner corner support members may be used as previously described for other types of custom enclosures.

[00321] With respect to the laboratory 2200, and other custom enclosures that may be constructed using the various components and construction techniques described herein, the surfaces of the interior wall panels are generally flat and seamless (either due to the releasable connections of adjacent panels and/or use of a sealant), which enables more efficient and effective cleaning, sanitization and/or infection control methods to be performed as it relates to when these structures are used to provide sterile environments such as for laboratory and medical uses.

[00322] In another aspect, the modular design of releasable connection of the various building components, described in accordance with the teachings herein, allows custom enclosures to be easily made according to any size requirements since modular enclosures can be combined to create a larger custom enclosure. The interior wall panels may be releasably removed to provide more open interior space within the custom enclosure, such as in an open layout, and other structural elements such as roof support systems with posts in some cases and/or trusses in other cases may be used to provide the structural support needed for the roof system. Accordingly, the half-units 2202a-2208b may have different sizes or have different internal structures relative to one another depending on the design and operational requirements of the laboratory 2200.

[00323] In another aspect, exterior and interior wall panels for double-panel walls may also be releasably removed in order to increase the size of the custom enclosure. For example, some exterior and interior wall panels may be releasably removed to provide a doorway or allow for an open space for a new modular enclosure that may be releasably connected to an existing custom enclosure to increase its size. Alternatively, some exterior and interior wall panels allow for a modular design in that they are releasably attached and can easily be removed to allow for a direct expansion of the size of a room or area of a custom enclosure such as by increasing the width and/or length of the custom enclosure by adding interior and exterior wall panels that have a different alignment relative to the direction of the exterior and interior wall panels that were removed to provide new perpendicular and/or angled doublepanel walls.

[00324] In another aspect, the construction elements and construction techniques described herein can be used in building multi-level structures. For example, the corners where sidewalls abut may be reinforced with vertical support members (e.g., posts), the roof systems may be flat, and the wall systems and roof systems reinforced and made with material having the required strength to support the weight of one or more custom enclosures that are placed above in an upper level of the multi-level structure.

[00325] In another aspect, the modular design and the use of air-tight seals, as described previously, for the double-panel walls and the use of separate air handling systems for each lab unit allows for multiple air locks within the laboratory units. For example, the regions labelled 2218a and 2218b in the lab unit 2206 shown in FIG. 22B may be maintained as an air lock to prevent any contaminants within the lab space from escaping to the outside environment.

[00326] Constructing laboratory units from the custom enclosures described herein such that they are provided with airtight seals, independent air handling systems to vary pressure therein as well as custom electrical and backup power, allows these laboratory units to be built to meet various standards such as Containment Level 2 (CL2) or CL3 standards which are used for work with medium risk biological agents and hazards as well as other various codes such as various building codes depending on the use of the custom enclosure.

[00327] In general, the interior wall panels, the exterior wall panels, the roof panels, the ceiling tiles, and the various longitudinal support beams and connection beams of the mobile unit 300, the custom enclosure 2100 and other custom enclosures made using the construction elements and construction techniques described herein may be formed using materials such as metals, polymer materials, composite materials or recycled materials that can provide the required structural strength and/or rigidity. Examples of metals include aluminum, marine grade aluminum, or steel. For example, AL 5052 marine grade aluminum may be used. The marine grade aluminum is lightweight, and it may also provide corrosion resistance and may tolerate constant contact with water. Alternatively, in at least one embodiment, the exterior wall panels and the roof panels may be formed of another metal such as, for example, A36, 44W, or any other suitable ASTM grades. Examples of polymer materials include, but are not limited to, plastics, thermoplastics, carbon fiber, and carbon-fiber based thermoplastic materials. Composite materials may include materials that have been 3D-printed, examples of which are described with respect to FIG. 23. Recycled materials can be reclaimed materials from previous structures that have been disassembled and repurposed. As another alternative, the construction elements may be powder coated or spray coated with an anti-corrosive spray or the construction elements may be galvanized.

[00328] In another aspect, the materials that are used for the aforementioned elements may inherently be fire retardant or coated with a fire resistant material. For example, the interior and exterior wall panels, the ceiling tiles, the floor panels (not shown) and the roof panels may be coated with a fire-retardant spray to prevent damage to the interior of the mobile unit 300, enclosure 2100 or other custom enclosure.

[00329] The particular type of material and/or coating that is used for one of the construction elements described herein is selected to meet the requirements of the construction element including rigidity, resistance to stress, and safety factors (e.g., fireproof, bulletproof, etc.).

[00330] The various construction elements described herein may be made using more conventional metal forming techniques and cutting. For example, laser cutting may be used. Alternatively, 3D printing may be used to manufacture the construction elements and may significantly reduce any wasted materials. Advantageously, 3D printing may be used to create a compound construction element which would otherwise be constructed as two separate construction elements using conventional manufacturing techniques such as the longitudinal support beam 2108a and the longitudinal connection member 2120. In fact, 3D printing may be used to create various different geometric shapes which may be used for various purposes such as the male and female connection elements described herein.

[00331] In addition, two or more materials may be used with 3D printing to create a compound material that may be used to manufacture construction elements where the compound material has certain desired characteristics, such as strength and/or flexibility, and/or certain properties such as being fire retardant and/or anti-corrosive. For instance, referring now to FIG. 23, shown therein is an example of a compound material 2300 that may be constructed on a printing table 2302 using a 3D layering technique which blends one type of material 2302a and 2302b (e.g., type 1 material) with another type of material 2304 (e.g., type 2 material). This manufacturing technique may be used to create certain areas in the material having increased strength such as where the type 2 material is shown. Such a compound material may be used for various construction elements described herein such as the interior wall panels, the exterior wall panels and/or the roof panels described herein. Examples of materials that may be used for the type 1 and type 2 materials include, but are not limited to, carbon fiber, thermoplastic or carbon-fiber based thermoplastic. Carbon fibers are advantageous as they have greater strength than steel.

[00332] Referring now to FIGS. 24A-24C, shown therein are front perspective, magnified front perspective and rear perspective views of an example embodiment of a double-panel wall system 2400 including first and second wall panels 2401 and 2402 that may be used for internal walls in a custom enclosure in accordance with the teachings herein. The wall panels 2401 and 2402 each have at least one interface component on both side surfaces and bended rear surfaces similar to other pairs of interior and exterior wall panels described herein, such as wall panels 600 and 700, respectively, except that wall panels 2401 and 2402 are used for internal walls, which may be done for creating rooms within a custom enclosure, for example. For ease of discussion, only some elements of the wall panels 2401 and 2402 are numbered. There may be multiple instances of wall panels 2401 and 2402 where planar adjacent wall panels are laterally connected and facing panels are horizontally connected to one another in a similar fashion as explained for previous wall panels described herein to form larger wall segments.

[00333] Wall panels 2401 and 2402 include upper channels 2401 c which may be used to suspend the wall panels 2401 and 2402 and move them to a certain location for installation. The channels 2401c may also be used to fasten together adjacent wall panels that are connected in a lateral fashion to build a larger wall section.

[00334] On one side surface of wall panel 2401 there is at least one interface component 2403 with a male portion 2403m, such as a tab, and a cutout 2403s. The cutout 2403s is a rectangular cutout that does not have to have the shape of the tab of the male portion 2403m. On the other side surface of the wall panel 2401 , there is at least one interface component 2405 which may be a narrow slot that is sized to be slightly larger than the male portion 2403m which allows for the lateral connection of another wall panel that has the same structure as wall panel 2401. The interface components on both side surfaces of the wall panel 2401 are at corresponding heights to allow these interface components to mate with corresponding interface components of an adjacent wall panel having the same structure as wall panel 2401 . For increased structural stability, there may be several of the interface components 2403 and 2405 that are spaced apart on the side surface of the wall panel 2401 .

[00335] On a rear surface (which may be a bended surface) of the wall panel 2401 there is another interface component 2404 that is a female connector in the form of a slot and similar in shape as the slot of interface component 1108. On the other bended rear surface (not shown) of the wall panel 2401 , there is at least one interface component 2406 with a similar slot. For increased structural stability, there may be several of the interface components 2404 and 2406 that are spaced apart on the rear bended surfaces of the wall panel 2401 . [00336] The wall panel 2401 also includes at least one set of cutouts 2407 which may be at a lower half portion of the wall panel 2401 . The set of cutouts 2407 may be used for passing wiring, pipes and other infrastructure components between wall panels that are laterally adjacent to one another. The example in FIGS. 24A-24C includes two sets of cutouts 2407.

[00337] The wall panel 2401 may also include at least one bottom support tab located at the bottom of the wall panel 2401 and directed inwards. In this example, there are two bottom support tabs 2408a and 2408b. The bottom support tabs 2408a and 2408b may be used to fasten the wall panel 2401 to a support structure such as flooring or support beams. Accordingly, the support tabs 2408a and 2408b may have apertures for receiving fasteners such as screws or bolts. The support tabs 2408a and 2408b may also be used to retain objects that are placed within the cavity of the wall panel 2401 so that the objects do not fall out the bottom of the wall panel 2401 when the wall panel 2401 is lifted. Examples of such objects include blocks of insulation.

[00338] The wall panel 2402 is similar to wall panel 2401 and has at least one interface component 2409 on one side surface that is a female component in the shape of a wide slot and at least one interface component 2410 on another side surface that has a male component 2410m and a cutout 2410s. The slot 2409 is a wide slot which allows for the lateral connection of the male interface component of another wall panel that has the same structure as wall panel 2402. The interface components on both side surfaces of the wall panel 2402 are at corresponding heights to allow these interface components to mate with corresponding interface components of an adjacent wall panel having the same structure as wall panel 2402. For increased structural stability, there may be several of the interface components 2409 and 2410 that are spaced apart on the side surface of the wall panel 2402. The wall panel 2402 also contains sets of cutouts on the side surfaces for similar reasons as the set of cutouts 2407 of wall panel 2401. The wall panel 2402 also includes an L-shaped slot 2411 at the bottom ends of the side surfaces which allows the wall panel 2402 to be mounted and releasably fixed to an angle iron or L-bracket as described for other embodiments of wall panels.

[00339] In at least one embodiment, any of the wall panels described herein may have an indicator to show direction of installation when the wall panels are being connected to one another laterally. An example of this is indicator 2401 i in FIG. 24B.

[00340] Referring now to FIG. 24D, shown therein is a side view of the interior double-panel wall having wall panels 2401 and 2402 and a portion of a floor system including a support beam 2412, with a roughing floor layer 2413 (also called a sub-floor layer) and finishing floor panels or floor tiles 2414 and an L- bracket 2415. The support beam 2412 may be similar to the longitudinal support beam 2108a-2108d, for example. The L-bracket 2415 may be attached to the sub-floor 2414 using fasteners such as bolts or screws, for example. The wall panel 2402 is then placed on top of the L-bracket 2415 such that the vertical portion of the L-bracket 2415 is received in the L-shaped slot 2411. The bottom portion of the wall panel 2402 may then be secured to the vertical portion of the L-bracket 2415 through fasteners like screws or bolts, for example. The L- bracket 2415 is preferably longer that the width of the wall panel 2402. Alternatively, there may be multiple L-brackets 2415 on the floor which slidably engage the L-slots 2411 at either side of the wall panel 2402 and cover more than 50% of the length of the wall panel 2402. In at least one embodiment, there may be further support that is provided at the top of the wall panels 2401 and 2402 by a ceiling system or cross beams (both not shown). It should be understood that the end side surfaces of the wall formed by wall panels like wall panels 2401 and 20402 may be against another wall or may be flashed and sealed or otherwise finished so that they are not exposed. In at least one embodiment, the floor tile 2414 may be made from material such as, but not limited to, vinyl material used for hospital floors. In at least one embodiment, the sub-floor layer 2413 may be continuous or discontinuous (which assists with sound attenuation). [00341] Referring now to FIGS. 24E-24F, shown therein are front and rear perspective views of an example embodiment of another double-panel wall system 2420 which may be used for external walls or internal walls of a custom enclosure in accordance with the teachings herein. The wall panels 2421 a and 2421 b are exterior wall panels while the wall panels 2422a and 2422b are interior wall panels. The wall panels 2421 a, 2421 b and 2422a, 2422b each have at least one interface component on both side surfaces and bended rear surfaces similar to other pairs of interior and exterior wall panels described herein, such as wall panels 2401 and 2402, respectively, except for the location and shapes of certain interface components and cutout holes. For ease of discussion, only some elements of the wall panels 2421a, 2421 b and 2422a, 2422b are numbered. There may be multiple instances of wall panels 2421 a, 2421 b and 2422a, 2422b where planar adjacent wall panels are laterally connected and facing panels are horizontally connected to one another in a similar fashion as explained for previous wall panels described herein to form larger wall segments.

[00342] On one side surface of wall panel 2421a, 2421 b there is at least one interface component 2423 with a male portion 2423m, such as a tab, and a cutout 2423s. The cutout 2423s is a rectangular cutout similar to cutout 2403s. On the other side surface of the wall panel 2421 a, 2121 b, there is at least one interface component 2425 which may be a narrow slot that is sized to be slightly larger than the male portion 2423m which allows for the lateral connection of another wall panel that has the same structure as wall panel 2421a, 2421 b. The interface components on both side surfaces of the wall panel 2421a, 2421 b are at corresponding heights to allow these interface components to mate with corresponding interface components of an adjacent wall panel having the same structure as wall panel 2421a, 2421 b. For increased structural stability, there may be several of the interface components 2423 and 2425 that are spaced apart on the side surface of the wall panel 2421a, 2421 b.

[00343] The rear bended surfaces of the wall panels 2421a, 2421 b and 2422a, 2422b have interface components (not shown) as was described for other embodiments of wall panels described herein. The wall panels 2421a, 2421 b and 2422a, 2422b also include at least one set of cutouts 2424 which may be at a lower third portion and mid portion of the wall panels 2421 a, 2421 b and 2422a, 2422b. The set of cutouts 2424 may be used for passing wiring, pipes and other infrastructure components between wall panels that are laterally adjacent to one another. The example in FIGS. 24E-24G includes two sets of cutouts 2424. The wall panel 2421 a, 2421 b also includes an L-shaped slot 2427 at the bottom ends of its side surfaces which allows the wall panel 2421a, 2421 b to be mounted and releasably fixed to an angle iron or L-bracket as described for other embodiments of wall panels.

[00344] The wall panel 2422a, 2422b is somewhat similar to the wall panel 2421a, 2421 b and has at least one interface component 2427 on one side surface that is a female component in the shape of a wide slot and at least one interface component 2428 on another side surface that has a male component 2428m and a cutout 2428s. The slot 2427 is a wide slot which allows for the lateral connection of the male interface component of another wall panel that has the same structure as wall panel 2422a, 2422b. The interface components on both side surfaces of the wall panel 2422a, 2422b are at corresponding heights to allow these interface components to mate with corresponding interface components of an adjacent wall panel having the same structure as wall panel 2422a, 2422b. For increased structural stability, there may be several of the interface components 2427 and 2428 that are spaced apart on the side surface of the wall panel 2422a, 2422b. The wall panel 2422a, 2422b also contains sets of cutouts on the side surfaces for similar reasons as the set of cutouts 2424 of wall panel 2421a, 2421 b.

[00345] Referring now to FIG. 24G, shown therein is a front perspective view of an example embodiment of another double-panel wall system 2429 which may be used for external walls of a custom enclosure in accordance with the teachings herein. The wall panels of the wall system 2429 have a similar structure as the wall panels of the wall system 2420 except that they are shorter. This allows the wall panels of the wall system 2429 to be used above a doorframe (an example is shown in FIG. 24N) or above and below a window frame (an example is shown in FIG. 240).

[00346] Referring now to FIG. 24H-24K, shown therein is a side view, an exploded perspective view and two magnified views of the exploded perspective view, respectively, of an example embodiment of another wall panel system 2430 in accordance with the teachings herein. The wall panel system 2430 may be used for exterior walls of a custom enclosure. Insulation (not shown) may be included in various locations of the wall panel system 2430 for some applications.

[00347] The wall panel system 2430 includes a rain cap 2431 , an exterior wall panel 2432, an exterior plate 2433, a wood structure 2434, a first drywall sheet 2435, steel studs 2436, a second drywall sheet 2437 and a third drywall sheet 2438. While these elements are referred to in the singular and reference numerals are used for one instance of these elements in FIG. 24I, it should be understood that there are multiple instances of these elements that are laterally distributed such that a wall section made using the wall panel system 2430 has a layer of exterior wall panels, a layer of exterior plates, one or more wooden structures (depending on the length of the wall section, a first drywall sheet layer with several drywall sheets, several pairs of steel studs, a second drywall sheet layer with several drywall sheets and a third drywall layer.

[00348] A custom enclosure that is made using the wall panel system 2430 may have insulation requirements and so insulation may be included at one or more layers of the wall panel system 2430 including the cavities of the exterior wall panels, the spaces between adjacent studs of the wooden structure, the spaces between adjacent steel studs, or any combination thereof. In this example, the wooden structure and steel studs layer have insulation.

[00349] The exterior wall panel 2432 has one side surface with at least one interface component 2432s, two rear bended surfaces that have at least one interface component 2432h and another side surface with at least one interface component (both not visible in FIGS. 24H-24K). The interface component 2432s may be a female component such as a wide slot, while the interface component at the same height on the other side surface may be a male component that can mate with interface component 2432s of an adjacent exterior wall panel that has the same structure as exterior wall panel 2432. The interface component 2432h is a narrow slot that is sized to receive a corresponding male component (e.g., hook) from a horizontally offset exterior plate 2433. For increased structural stability, there may be several of the interface components 2432s on the side surface that are vertically spaced from one another, several of the interface components on the other side surface that are vertically spaced from one another and several of the interface components 2432h that are vertically spaced apart on the bended rear surface of the wall panel 2432 for making several connections with laterally adjacent exterior wall panels and with horizontally offset flat panels 2333.

[00350] The wall panel 2432 includes at least one cutout 2432c which may be at a lower bottom portion of the wall panel 2432. The cutout 2432c may be used for passing wiring, cables, pipes and other infrastructure components between the exterior wall panels that are laterally adjacent to one another. The wall panel 2432 also includes an extension portion 2432c that may be connected to a portion of the floor system that the wall panel 2432 is attached to during manufacturing or installation. The exterior wall panel 2432 may also include apertures 2432a to facilitate the attachment of the exterior wall panel 2432 to a portion of the floor system or other objects such as the exterior plate 2433. The exterior wall panel 2432 may also include apertures 2432p at upper end portions of the side surfaces of the exterior wall panel 2432. The apertures 2432p may be used to support the wall panel 2432 when it is moved into place using construction equipment for installation. The apertures 2432p may also be used as another connection location to fasten together laterally adjacent wall panels 2432.

[00351] The rain cap 2431 is a trim piece that has a top longitudinal strip with inner and outer downward extending portions on either side of the longitudinal strip to form a U-shaped channel 2431c. The rain cap 2431 also has a downward slanted strip 2431 s extending away from the outer downward extending portion for deflecting away environmental elements, such as rain or snow, from the outer surface of the exterior wall panels 2432. The channel 2431c may be large enough so that the rain cap 2431 slidably receives the top of the exterior wall panel 2432 and the rain cap is secured to the exterior wall panel 2432 with suitable fasteners. Alternatively, the width of the channel 2431c may be large enough so that the rain cap 2431 also slidably receives the exterior plate 2433 and the rain cap is secured to the exterior wall panel 2432 and the exterior plate 2433 with suitable fasteners. The rain cap 2431 may be optional in some cases.

[00352] The exterior plate 2433 is a flat panel that replaces the interior wall panels described herein in this wall panel system 2430 which allows for a reduced thickness for the exterior wall compared to embodiments where interior wall panels are used. This structure may also provide improved fire rating as it allows the exterior wall panel 2432 to act as a cladding and wires can be run through the cavities of the exterior wall panels 2432. The same materials may be used to make the exterior wall panels 2432 and the exterior plates as described for other wall panel systems herein.

[00353] The exterior plate 2433 includes a plurality of apertures 2433a arranged in columns that may be used to pass electrical, mechanical and/or structural components therethrough. The apertures 2433a also allow the exterior plate 2433 to be made using less material which reduces manufacturing costs as well the weight of the wall panel system 2430. The width of each exterior plate 2433 may be selected so that one piece of exterior plate 2433 releasably engages two laterally adjacent exterior wall panels.

[00354] The exterior plate 2433 includes interface components in the form of slots 2433s, as described for previous wall panels, that are engaged by the interface components (e.g., male components 2433m) of the exterior wall panels 2432 so that the plate 2433 is engaged with the exterior wall panel 2432 in a horizontally offset manner. In an alternative embodiment, the interface components of the exterior plate 2433 may be male components and the corresponding interface components exterior wall panel 2432 may be female components. The interface components of the exterior plate 2433s are spaced apart at the same height so that they collectively engage with interface components of two adjacent exterior wall panels. In at least one alternative embodiment, there may be a plurality of interface components on the exterior plate 2433 formed along several rows where each row is located between upper and lower apertures 2433a.

[00355] The wood structure 2434 is a wooden frame with several wood studs that is attached to the inner surface of the exterior plate 2433 which is the surface of the exterior plate that faces towards the inside of the custom enclosure. This attachment may be through fasteners that engage apertures 2433h on the plate 2433 and extend into the wood structure 2434. be Insulation may optionally be placed between the wood studs of the wood structure 2434. The wood structure 2434 includes a lower wood beam 2434p that extends longitudinally along the bottom of the wood structure 2434. The wood studs are attached so inward (e.g., directed towards the interior of the custom enclosure) facing surfaces are flush with an inward facing surface of the wood beam 2434 so that they are offset away from the outward facing surface of the wood beam

2434 which provides a surface upon which the exterior plate 2433 and the exterior wall panel 2432 are placed.

[00356] The first drywall sheet layer includes drywall sheets 2435 that are fastened to the wood structure 2435. For some applications, the drywall sheets

2435 are used as a finishing layer for the wall panel system 2430 and there are no additional layers. This may be done in cases where layers 2432 to 2435 are sufficient to meet thermal insulation requirements and additional layers may not be added due to reduced footprint for installation.

[00357] For applications where there are increased thermal insulation requirements, the wall panel system 2430 includes the steel studs 2436 and the second drywall layer including drywall sheets 2437. In alternative embodiments, other material having suitable strength and rigidity may be used instead of steel. The steel studs 2436 are attached to the drywall sheets 2435 and aligned with the wood studs of the wood structure 2434. Optionally, insulation material may be placed between adjacent steel studs 2436 to increase thermal and/or acoustic insulation for the wall panel system 2430. The drywall sheets 2437 of the second drywall layer may provide a surface that may be finished (i.e., taped and painted) for the wall panel system 2430 where additional insulation is not needed. Alternatively, a third drywall layer including drywall sheets 2438 may be fastened to the second drywall layer to provide additional thermal and/or acoustic insulation in which case the drywall sheets 2438 may act as a surface for finishing for the wall panel system 2430. The steel studs 2436 and drywall sheets 2437 and 2438 may be included to increase the fire rating for the wall panel system 2430 to meet the construction codes.

[00358] During installation, the lower wood beam 2434p of the wood structure 2434 may first be attached to the floor system, such as to a longitudinal support beam of a floor system. The exterior plates 2433 is then installed. The exterior plates 2433 contains a plurality of holes 2433h (see FIG. 24K) that receive fasteners for fastening the exterior plates 2433 to the wood structure 2434. The exterior panels 2432 may then be attached to the exterior plates 2433 by mating the interface components on the inward facing surfaces of the exterior panels 2432 to the interface components on the outward facing surfaces of the exterior plates 2433. There may be spaces in the wood structure 2434 where wires, piping and other infrastructure components may be run, and corresponding holes located in the sheet 2435 where receptacles are installed in cases where the steel studs 2436 and drywall sheets 2437 and 2438 are not used. In cases where the steel studs 2436 and drywall sheets 2437 and 2438 are used, there can be corresponding holes for the receptacle mounting.

[00359] In an example embodiment, the drywall sheets 2435, 2437 and 2438 may have a thickness of 5/8 inches and provide an insulation level of R5 per inch of thickness. The steel stud layer may include insulation to also provide an insulation level of R5 per inch of thickness. The steel studs may be 1 ! x 21 in size. [00360] In at least one embodiment, certain components of the wall panel system 2430 may have different heights. For example, the exterior wall panel 2432 and the exterior plate 2433 may have a first height, the wood structure 2434 and layer of drywall sheets 2435 may have a second height while the steel studs 2436 and the layers of drywall sheets 2437 and 2438 may have a third height. The first, send and third heights do not have to be the same. Generally, the first height is larger than the second height. The third height may be larger than the second height to allow for the placement of other structures above the wood structure 2434 such as longitudinal support beams to improve structural stability (e.g., see FIG. 24L).

[00361] Referring now to FIG. 24L, shown therein is a cross-sectional view of an end portion of a unit of a custom enclosure 2440 that uses the internal double-panel wall and external wall panel system of FIGS. 24A-24K. The roof system is not shown. Insulation materials are not shown but may be included depending on the thermal requirements for the enclosure 2440. The enclosure 2440 may include pads 2441 that run along its perimeter. Longitudinal support beams 2442 are placed on top of the pads 2441 and run along edges of the unit and cross beams 2423 of the floor system run perpendicular and are connected to the longitudinal support beams 2442 (similar to what was described and shown in FIGS. 21A-21 E). A layer of corrugated sheets 2444 may then be placed on top of the cross beams 2423 to provide a base and strength for the floor system. Insulation may be added to the channels of the corrugated sheets 2444 to provide thermal insulation and/or acoustic attenuation for the custom enclosure 2440.

[00362] Panels for a subfloor 2445 may then be installed on top of the corrugated sheets 244. The subfloor 2445 may be continuous. Panels for another subfloor 2446 may be installed on top of the subfloor 2445. The subfloor 2446 may be discontinuous to aid with sound attenuation. Sheets of plywood (e.g., % inch) may be used for both subfloors 2445 and 2446. A finishing layer for the floor may be installed on top of the subfloor 2446. For example, the finishing layer for the floor may be floor tiles or material that is used in hospitals or schools. In some embodiments, one of the subfloor 2445 and 2446 may be optional.

[00363] Also shown in FIG. 24L are exterior wall panel systems 2448 and 2453 that may be made using the wall panel system 2430. The bottom beam of the wood structure of the exterior wall panel system 2448 sits on the longitudinal support member 2442 to provide a thermal break. The exterior wall panel of the exterior wall panel systems 2448 is full height and extends to the top of the custom enclosure 2440. The wood structure and adjacent drywall layer of the exterior wall panel system 2448 is shorter and a longitudinal support beam 2449 is installed above the wood structure. Cross beams 2451 may be connected to the longitudinal support beam 2449 and panels (e.g., drywall) from a roof support layer 2452 provide support for the roof system (not shown).

[00364] The ceiling system 2449 is constructed using a plurality of tiles or panels that may be suspended from the cross beams 2451 defining a ceiling cavity therebetween 2450 within which various mechanical, electrical or other infrastructure components may be run as was described for custom enclosure 2100, for example.

[00365] The interior wall panel system 2447 may be made using the wall panel system 2400. One of the wall panels of the wall panel system 2447 may be attached to an L-bracket 2447L that is in turn attached to one of the floor components such as sub-floor 2445, for example. The interior wall panel system 2447 may be used as a partition wall to form a room within the custom enclosure 2440. The interior wall panel system 2447 may have a height that extends up to the ceiling system 2449.

[00366] Referring now to FIG. 24M, shown therein is a cross-sectional view of a portion of a custom enclosure 2458 showing the exterior wall and roof system (the ceiling system is not shown for simplicity of illustration). The custom enclosure 2458 includes an exterior wall panel system 2460 that is made according to the exterior wall panel system 2430 of FIGS. 24H-24K. The custom enclosure 2458 may also include an eavestrough structure 2479 for draining water to the ground. [00367] The exterior wall panel system 2460 includes a roof cap 2461 , an exterior wall panel 2462, an exterior plate 2463, a wood structure 2464, a first drywall layer 2465, a steel stud layer 2466, a second drywall layer 2467 and a third drywall layer 2468. The exterior wall panel 2462 does not include insulation. However, insulation material 2469 is included in the wood structure 2464 and can be wrapped around the studs of the wood structure 2464. In addition, or alternatively in some cases, insulation material 2470 may also be included in the steel stud layer 2466 by being wrapped around the steel studs.

[00368] The custom enclosure 2458 includes longitudinal support beams 2471 and 2472. The longitudinal support beams 2471 run parallel with the exterior wall panel system 2460 and are mounted on top of the wood structure 2464. An upper wood beam of the wood structure 24234 acts as a thermal break. The longitudinal support beams 2472 are perpendicular to the exterior wall panel system 2460 and provide support for the roof system. The ceiling system may be suspended from the longitudinal support beams 2472 in some embodiments.

[00369] The roof system includes sheets of corrugated steel 2473 that are mounted on the longitudinal support beams 2472 to provide strength and rigidity for the roof system. Material other than steel may be used for any corrugated steel sheets described herein where the material has suitable strength and rigidity properties. A first sub roof layer is installed on top of the corrugated sheets 2473. A second sub roof layer 2475 is installed spaced apart from the first sub roof layer and insulation 2478 may be installed in this space. Roof panels 2476 may then be installed on the second sub roof layer 2475. As shown, the roof system may be implemented so that the outermost surface is sloped in some areas. In at least one alternative embodiment, a roof truss structure may be used.

[00370] Referring now to FIG. 24N, shown therein is an example embodiment of a portion of custom enclosure 2480 that incorporates the wall panel systems of FIGS. 24A-24K (the ceiling and roof systems are not shown for ease of illustration). For example, the exterior walls 2481 of the custom enclosure 2480 are made using the exterior wall panel system 2430 that are installed on top of longitudinal support beams 2482. The exterior wall panel section 2483a on top of the door, and the exterior wall panels 2483b and 2483c above and below the window may be made using the exterior wall panel system 249. The interior wall panel sections 2484a, 2484b and 2484c can be made using the wall panel system 2400. The enclosure 2480 also includes a roof support structure 2485 that is made up of longitudinal support beams and cross beams as described for the custom enclosures 2440 and 2458. The enclosure 2480 also includes vertical support members 2487 that are used to support the roof support structure 2486.

[00371] The ceiling panel system (not shown) may be suspended from the roof support structure 2486. For example, the ceiling panel system can be hung by wires that are connected to joists of the roof support structure 2486. In at least one embodiment, there may also be a track and grid that is hung from the roof support structure 2486 then place ceiling tiles can be placed in the grid.

[00372] The portion of the custom enclosure 2480 is formed from units 2480a and 2480b which may be separately constructed, transported to the installation site and then installed by connecting abuting components such as the roof support structure where the adjacent longitudinal support members are connected together, an example of which is shown at region 2485a. Similarly adjacent vertical support posts are connected together, an example of which is shown at region 2487a. In a similar manner other adjacent components of the two units 2480a and 2480b are fastened together.

[00373] It can also be seen that the north east side of the custom enclosure 2480 is “open” so that another unit can be attached to this open side to increase the size of the custom enclosure. For example, referring now to FIG. 240, shown therein is an example embodiment of a portion of a custom enclosure 2490 (the ceiling and roof systems are not shown for ease of illustration). The custom enclosure 2490 is made by attaching custom enclosure 2480’ to another unit 2492 by attaching various adjacent components from both of these structures, an example of which is shown for the longitudinal members of the roof support structures at region 2494. Custom enclosure 2480’ is somewhat similar to custom enclosure 2480 except for additional windows.

[00374] Referring now to FIG. 25, shown therein is a flow chart for an example embodiment of a method 2500 for assembling a custom enclosure, such as custom enclosure 2100, 2480 or 2490 in accordance with the teachings herein. The steps of the enclosure assembly method 2500 may be modified or implemented in a different way depending on the nature of the enclosure that is being constructed (e.g., medical, laboratory, classroom, etc.) and the space that is available at a manufacturing facility. For certain manufacturing spaces and assembly setups, a plurality of the double-panel walls may be assembled to form various wall sections (e.g., pre-fab) which are then dropped into place in the custom enclosure. Alternatively, for other manufacturing spaces and assembly setups, the enclosure may be constructed in place (e.g., in situ), such as by following steps 2508 to 2154, with various wall panels being installed one at a time. It should be understood that the method 2500 is provided as an example and may be modified when assembling different enclosures. For ease of illustration purposes only, the assembly method 2500 will be described in relation to the custom enclosure 2100.

[00375] At step 2502, the roof and floor skeleton structure may be assembled. This may be done as was described for floor system 2104, in which a first set of longitudinal support beams for a portion of the floor system 2104 may be releasably attached to one another, such as longitudinal support beams that may be in-line with the longitudinal support beam 2108a and then first ends of cross members 2106 may be releasably connected thereto. Once that is done, a second set of longitudinal support beams may be releasably connected together in a linear fashion and then releasably connected to the other ends of the cross members 2106. Alternatively, both sets of longitudinal support members for the floor system may be assembled first and then opposing ends of the cross beams may be releasably connected to the sets of longitudinal support members to build out the floor system 2104. This may be repeated several times depending on the size of the enclosure. For example, custom enclosure 2100 is a double-room enclosure so the above operations are performed twice to build out two sections of the floor system 2104.

[00376] Vertical support posts 2114 are then connected to the lower longitudinal support members of the skeletal floor structure. Longitudinal support members and cross beams for the roof support structure (as was described for enclosures 2440 and 2458) may then be assembled and attached to the vertical support posts 2114. The number of vertical support members and the upper longitudinal members may be installed as needed depending on the size of the custom enclosure. For example, when the custom enclosure is a double-width, triple-width or larger custom enclosure, then a roof support structure and one or more posts, such as roof support structures 2112 and vertical support posts 2114, for example, may be used to build. Alternatively, or in addition thereto, a truss system may also be used as described earlier to provide an additional roof support structure.

[00377] The upper longitudinal support members that are used may depend on whether a cable tray is needed in which case longitudinal support members 1650 or 2002 may be used. Alternatively, if a cable tray is not needed then the longitudinal support members 1606 may be used or another type of upper longitudinal support member, if needed. The upper longitudinal support members may be selected based on the size of the spacing between the downward side portions that is selected so that the channel defined therebetween is large enough to releasably and slidably receive one or more horizontally offset wall panels of the wall system. An example of the skeleton structure for the roof support structure and the vertical posts is shown in FIGS. 24N and 240.

[00378] In some cases, the layout for the skeleton for the vertical support posts and the upper longitudinal support members depends on the manufacturing technique used to form the walls (see step 2506) and/or whether certain objects will be dropped into place during assembly in which cases some sections of the roof structure may not be connected to provide space for this “drop assembly”. [00379] At step 2504, other elements of the floor system may be installed such as two or more subfloor layers that may be installed on top of the longitudinal support beams and cross beams of the floor skeleton. A first subfloor layer may be a corrugated layer with sufficient strength, such as a corrugated steel sheets, to provide strength and support for the floor of the custom enclosure. Additional subfloor layers may be added on top of the corrugated layer such as continuous or discontinuous (for sound attenuation) floor layers. There may be several subfloor layer that are used as was described for custom enclosure 2440. As described earlier, in at least one embodiment, when the floor system is assembled, other functional elements can be installed such as, but not limited to, mechanical floor access panels, water supply pipes and drainage pipes, floor electrical access ports and any other floor entry points or structural components as needed.

[00380] Another step of the floor system assembly is the installation of L- brackets on various locations of the floor system where wall panels will be installed. For example, the L-backets are installed close to the perimeter of the enclosure where double-panel wall, multi-panel wall or exterior panel wall systems may be installed. The L-brackets may also be installed at locations where interior double-wall panels may be located. The L-brackets may be installed to the longitudinal connection members (e.g., Z channel beams 2120) used for the floor system for defining locations where external wall sections are to be installed. Other L-brackets may be installed to the longitudinal support members that are not at the periphery of the custom enclosure to define locations where internal walls (e.g., partition walls) are to be assembled.

[00381] At step 2506, it is determined whether there is sufficient space at the manufacturing facility and whether the manufacturing assembly line is set up to assemble wall sections fully and later install them to the floor system (e.g., modular construction) in which case the method 2500 proceeds to step 2516 or whether the wall panels should be installed in situ, one at a time, on the floor system in which case the method 2500 proceeds to step 2506. [00382] At step 2508, the interior wall panels may be assembled by releasably connecting the interior wall panels to the floor system as well as to each other. This may be done one wall at a time, so the interior wall panels for wall 2108a may first be assembled and releasably connected to the floor system 2104. This step may involve releasably attaching a first interior wall panel may be releasably attached to the longitudinal connection member, which may be done as was explained with reference to FIGS. 21 B and 21 C. Then a subsequent interior wall panel may be releasably attached to the previous installed wall panel, which may be done in a similar manner as was explained with reference to FIG. 7, or FIGS. 13A and 13B, for example, depending on the embodiment of the interior wall panel that is used. This subsequent interior wall panel may then be releasably attached to the longitudinal connection member. This process is repeated until all of the interior wall panels for a given wall are assembled. This may also be done for interior wall panels that are used for the exterior walls of the custom enclosure as well as interior walls of the custom enclosure. Any of the interior wall panels that make contact with an upper longitudinal support member (that may be part of the roof support structure) may be releasably fastened thereto. Athermal break may be optionally installed between the upper surface of the longitudinal connection member and the lower surfaces of the interior wall panels or between the longitudinal connection members and the longitudinal support members.

[00383] At step 2510, various components may be installed along the cavities of the interior wall panels as needed depending on the nature and operational requirements of the custom enclosure. For example, electrical wires, communication cables, power lines, gas lines as well as other mechanical, electrical and/or infrastructure components may be installed.

[00384] At step 2512, if any of the walls of the custom enclosure are multipanel walls having three or more horizontally offset wall panels, then the intermediate wall panels may be installed for those particular walls. Accordingly, step 2512 is optional depending on the design of the custom enclosure. Although not shown in FIGS. 21 B-21 C, for any walls that have three or more horizontally offset wall panels, the widths of the floor longitudinal support beams and longitudinal connection members may be increased accordingly in order to be able to accommodate/support the additional intermediate wall panels. The intermediate wall panels may be assembled one at a time by first positioning a given intermediate wall panel for releasable attachment to a corresponding horizontally offset interior wall panel (or horizontally offset intermediate wall panel when there is more than one intermediate wall panel layer) while also positioning the given intermediate wall panel for releasable attachment to a laterally offset previously installed intermediate wall panel and then moving the given intermediate wall panel into its final position, which may be done as was described for FIGS. 14F and 14G (and FIGS. 14A and 14B if the exterior wall panel in those figures is treated as an intermediate wall panel). Certain material may also be placed in the cavities of the intermediate wall panels depending on their functionality (an example of this was given in the description of FIG. 14G). These operations may be performed for each installed intermediate wall panel layer for a given wall of the custom enclosure before installing the next intermediate wall panel layer (if one exists) or the exterior wall panel layer. A thermal break may be optionally installed between the upper surface of the longitudinal connection member and the lower surfaces of the intermediate wall panels.

[00385] At step 2514, the exterior wall panels are then assembled for each wall. This may be done in a similar manner as the intermediate wall panels. Accordingly, this may be done one wall panel at a time, so a first exterior wall panel for wall 2108a may first be releasably attached to an opposite interior wall panel (or an intermediate wall panel if it exists) in accordance with the teachings herein and then this first exterior wall panel can be releasably connected to the floor system 2104 and to any longitudinal support member (that may be part of the roof support structure) that the top of the exterior wall panel makes contact with. Subsequent exterior wall panels are then releasably attached to the next horizontally offset wall panel (which may be an interior or intermediate wall panel) while at the same time being releasably attached in a lateral manner to the adjacent exterior wall panel that has just been installed in accordance with the teachings herein (an example of which was explained with reference to FIGS. 14A and 14B), regardless of whether the exterior wall panel is being releasably attached to an intermediate wall panel or an interior wall panel. A spacer may be optionally installed above the upper surfaces of the wall panels and within the U shaped channel of the longitudinal support member. The spacer may be made from a thermal insulating material so that it acts as a thermal break.

[00386] If instead at 2506, it is determined to use a modular installation, then the various external and internal wall sections needed for the custom enclosure can instead be assembled in a manufacturing space at step 2516. This involves generally performing the same steps as described for steps 2508 to 2516 (without connecting any wall component pieces to the skeletal structure of the custom enclosure). This may be done by first assembling interior wall panels together and exterior wall panels together to inner and outer portions of wall sections at step 2516 and then installing any needed mechanical and/or electrical infrastructure components in the wall sections before attaching of the interior and exterior portions together at step 217 to form the wall sections (e.g., in a prefab manner). Next at step 2518, the entire assembled external wall sections (at the perimeter of the custom enclosure) and internal wall section (for internal walls like partition walls of the custom enclosure) may be “dropped into place” and connected to components of the floor system such as the L brackets as well as components of the roof skeletal structure such as certain upper longitudinal support members.

[00387] At step 2520, any inner and outer corner support members, such as inner and outer corner support members 2103i and 2103o, may also be releasably attached at this point to provide further structural stability to the walls of the custom enclosure. If there are any internal walls or half walls (as shown in the example laboratory structure of FIGS. 22A-22B), then similar corner support members and/or finishing trim pieces may be installed (such as those described with respect to the laboratory of FIGS. 22A-22B). [00388] At step 2522, the ceiling system is installed. This may be done such that the ceiling is a drop ceiling (e.g., false ceiling) or not as previously explained with respect to FIGS. 17 and 18 or FIGS. 20A and 20B. The ceiling panels may be releasably installed using fasteners placed on the top surface of the ceiling panels so that someone inside the custom enclosure cannot access the space above the ceiling panel for safety purposes. In some embodiments, at least a portion of the ceiling panels may be installed such that they are easily removable if access to the interior of the custom enclosure is needed from equipment that is outside of the custom enclosure such as a boom or a crane that is positioning equipment inside or removing equipment from the custom enclosure. Alternatively, the ceiling system may be installed based on the structure shown in FIGS. 24L and 24M and the ceiling system may be suspended from the roof support structure.

[00389] At step 2524, certain components such as wiring, cables, gas lines, as well as other electrical, mechanical and/or infrastructure components that have been installed inside the walls may be run along the top of the ceiling system as needed for connection to a maintenance room, an electrical room or certain fixtures (e.g., lights) or openings in the ceiling system.

[00390] At step 2526, the roof system may then be installed. This may be done as was previously described with respect to FIGS. 15A to 20B. The type of roof panels that are used may be roof panels 1500, 1900 or 2000, or other suitable roof panels may be used, depending on the application of the custom enclosure. For example, if the custom enclosure includes equipment which generate loud noises or have components that need to be removed for servicing or replacement, such as a large engine for example, then the roof panels 1900 with the sound attenuating properties may be used. Alternatively, if the custom enclosure is used for medical or laboratory purposes, then the roof panels 1500 or 2000 may be used. Alternatively, the roof system may be installed based on the structures shown in FIG. 24N or FIG. 240.

[00391] At step 2528, the finishes may be installed. This may include installing the finishing for the floor system where floor tiles or floor panels may be attached to the uppermost subfloor layer. The material for the floor tiles may be selected based on the application of the custom enclosure. For example, materials used for hospital flooring may be used when the custom enclosure is a healthcare facility. Alternatively, materials used for school flooring may be used when the custom enclosure is an educational facility. Inner surfaces of external walls and surfaces of internal walls may be finished as needed which may involve performing taping and painting drywall surfaces and/or install flashing on any exposed surfaces of wall panels and/or internal vertical support members.

[00392] It should be noted that in at least one alternative embodiment of the assembly method 2500, the floor system may be assembled at the same time and separately from the assembly of the side walls, ceiling and roof systems of the custom enclosure. The assembly of side walls, ceiling and roof systems may then be “slid over” the floor system and releasably attached thereto.

[00393] It will be appreciated that for the mobile unit 300 and the custom enclosure 2100, although not shown, at least one door and/or window can be included such as shown for the custom enclosures 2480 and 2490 in FIGS. 24N and 240, respectively . For windows, wall panels having different heights may be secured at lower and upper portions of a wall and a frame can be constructed for allowing a window to be mounted in an airtight fashion. For doors, a floor to ceiling door may be used in which case two sections of wall panels are assembled with side surfaces that are spaced apart where a door frame is constructed, and a door is mounted. Alternatively, wall panels may be cut to fit above the door panel, an example of which is shown in FIG. 21 L. This may be done such that there is an airtight seal when the door is in the closed position. In some cases, standard door frames may be used that may be attached via bolts, or other releasable fasteners, and any male connectors of adjacent wall panels may be taken off or bent such that the side surfaces of the wall panels that are adjacent to the door frame are smooth and have no protrusions. Once door frames are installed, doors can then be mounted therein. An example of this can be seen in FIGS. 22A and 22B, which show an example embodiment of a laboratory 2200.

[00394] In at least one embodiment described herein, the mobile unit 100 or custom enclosure 2100 can be combined with other similarly constructed structures, which may have other designs and/or purposes, but can be connectable to one another for forming compound structures of various configurations. An example of this is also shown with the laboratory of FIGS. 22A and 22B.

[00395] It will be appreciated that the construction of the wall, floor, ceiling and/or roof systems described herein within the mobile unit 300 as well as other mobile, semi-permanent, permanent custom enclosures, can be done more rapidly than can the formation of walls using conventional stud construction techniques, thereby to enable a mobile unit, or other semi-permanent, or permanent custom structure, to be constructed more rapidly so it can be deployed more rapidly, as well as to allow at least a portion of these structures to be easily and quickly disassembled for transport and reassembly at another site.

[00396] It should be noted that generally, in the various embodiments described herein, notwithstanding multi-level structures, the structural design of the multi-panel wall system allows for the creation of a custom structure that is physically stable such that no additional support is required.

[00397] In at least one embodiment, the ceiling panels described herein may be formed in a similar manner as some of the wall panels described herein, but without the features for interfacing with angle irons or other interconnection structures. Once in position, the ceiling panels may be releasably fastened together with bolts, or other fasteners, and then a sealant such as silicone, which may be industrial grade or medical grade depending on the use of the enclosure, may be applied to the gaps between adjacent ceiling panels if needed. A medical grade sealant is resistance to germs and certain types of chemicals. [00398] In at least one embodiment, a vapour barrier film may also be included in any of the custom enclosures described herein in order to control condensation. The vapour barrier film may be applied between at least one of the interior and adjacent exterior wall panels or at least one of the ceiling panels and the exterior walls of the housing and/or between at least one of the ceiling panels and the roof panels.

[00399] In at least one embodiment, once the various wall panels, floor panels and/or ceiling panels are assembled, a sealant, such as a silicone sealant, which may be medical grade, may be applied along the interfaces between one or more of these panels to provide an air-tight seal (for custom enclosures that have air-sealing requirements, such as a medical or laboratory structure). Alternatively, in at least one embodiment, the sealing material which is used may be mold resistant. Alternatively, in at least one embodiment, the sealing material which is used may be air-tight and mold resistant.

[00400] In addition, while particular lengths and formats of mobile units, semipermanent or permanent custom enclosures have been described and depicted herein, it will be understood that the fabrication and construction principles described herein are applicable to enclosures having different dimensions, whether being used to construct a shipping container or whether being used to construct a custom fabricated enclosure that incorporates the wall, roof, floor and/or ceiling elements described herein.

[00401] In at least one embodiment, a custom enclosure which is made using the materials and construction techniques described herein may be generally provided with air handling components and power components that are suitable for the use for the use of the custom enclosure. For example, when the mobile unit 300, custom enclosures 2100, 2440, 2458, 2480, 2490 or other custom enclosure is used as a medical unit, in order to provide electrical utilities thereto, these enclosures may be coupled to a 208 Volt, 50-Ampere connection via a manual transfer switch with connections for connecting to a backup generator, in at least one embodiment. In another embodiment, custom enclosures according to the teachings herein may further incorporate an electrical distribution system that incorporates or can connect with an uninterrupted power supply (UPS) for ensuring that power continues to be routed to key receptacles in these structures in the event of a municipal or facilities power failure. In at least one embodiment, power to these enclosures may be provided by alternate power sources such as renewable or non-renewable energy sources including, but not limited to, solar, wind, electric, natural gas, diesel, turbine and electric vehicles through a bi-directional charging station.

[00402] In at lest one embodiment, custom enclosures described in accordance with the teachings herein may be divided into patient rooms for medical purposes. In such cases, the floor system of each patient room may be clad with a medical-grade polyurethane floor such as the medical-grade Polyclad Pro PU available from Polyflor Limited in the United Kingdom. Alternative formats or suppliers of materials for the floor system that comply with the applicable quality and safety standards may be employed. In at least one embodiment, the floor system may feature a raised perimeter running six (6) inches up the walls, providing a floor-to-wall barrier to dirt, fluids and other contaminants. The floor system may be constructed, in at least one embodiment, such that it is suitable for use in ISO1466-11999 Class 4 clean rooms, and may be classified as a Class A product, including non-shedding to ASTM F51 , complying with CAN/ULC - S102.2. In at least one embodiment, the mobile unit 300, enclosure 2100 or other enclosure may have a floor made of structural steel, or another material having suitable strength and desirable properties such as the compound printed material described with reference to FIG. 23.

[00403] In at least one embodiment, custom enclosures described in accordance with the teachings herein that are usable for forming compound structures of various configurations, that may be mobile, semi-permanent or permanent, may be fully insulated to provide reliable operation within temperatures ranging from about -50°C (-22°F) to about 50°C (113°F). Alternatively, the insulation may be selected to enable another temperature range for custom enclosure described in accordance with the teachings herein based on the use of these structures. For example, at least one of the cavities that is formed between certain interior and exterior wall panels or between certain roof panels and ceiling panels and/or the basket 1920 may include insulation panels to provide the desired amount of insulation. Such insulation panels may be made of polystyrene or some other thermally insulating material and/or acoustic dampening material that has a size to allow for installation in the above-noted cavities and/or baskets.

[00404] It should be noted that the use of the terms “releasably attached”, “releasably coupled”, “releasably installed” and the like throughout the description means that two components may be fastened together such that the components are structurally secure and held firmly in place but can also be easily disassembled when needed. For example, the manner in which the roof panels and/or ceiling panels are removably attached to wall panels and other support elements allows for relatively simple disassembly of portions of the roof system and ceiling system to allow for access to the interior of an enclosure for various purposes such as installing or removing large equipment which cannot be moved through any doors or windows of the enclosure. Alternatively, portions of the roof system may be easily removed allowing for access to the region above the ceiling where certain components may require servicing. In either case, once the work is completed, the portions of the roof system and optionally the ceiling system that were removed may be easily reassembled to close the enclosure. This is in contrast to other conventional enclosures in which the roof system and/or ceiling system may be welded in place which makes it more difficult to disassemble and reassemble these elements.

[00405] While the applicant’s teachings described herein are in conjunction with various embodiments for illustrative purposes, it is not intended that the applicant’s teachings be limited to such embodiments as the embodiments described herein are intended to be examples. On the contrary, the applicant’s teachings described and illustrated herein encompass various alternatives, modifications, and equivalents, without departing from the embodiments described herein, the general scope of which is defined in the appended claims.
