Description:
INSULATIVE MATERIAL AND METHOD FOR INSTALLATION

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to and the benefit of U.S. Provisional Patent Application Number 62/448,690, filed 20 January 2017, and U.S. Provisional Patent Application Number 62/359,535, filed 07 July 2016, the disclosures of which are expressly incorporated herein by reference.

FIELD OF THE DISCLOSURE

[0002] The present disclosure relates generally to insulative material and more specifically to installing insulative material to a surface of a structure.

BACKGROUND

[0003] Insulating buildings can lower the cost to heat or cool the interior of the building. Along with exterior walls, other structures such as ceilings and floors may also be insulated. Insulating these structures can be achieved with, for example, spray urethane foam insulative materials or fiber insulative materials.

[0004] To achieve a desired insulative material rating for such a ceiling, some methods use a spray foam insulative material that may be more expensive than fiber insulative materials. Unfortunately, high R-value batt or roll insulative material is generally too thick to fit within the framing members of the ceiling to achieve a comparable R-value to the applied spray foam insulative material. Moreover, since most roof trusses are constructed out of 2 x 4's or 2 x 6's and typical insulative material in attic area is 6 inches to 12 inches thick, installing batt or roll insulative material in the trusses may be labor intensive and may require techniques that compress portions of the insulative material that therefore decrease the R-value.

The second face 24 of first framing member 14, the second face 30 of second framing member 16 and the inward face 12A of the deck 12 cooperate to define the cavity 20.

[0067] The cavity 20 has a width W1 that is defined by the distance between the second face 24 of the first framing member 14 and the second face 30 of the second framing member 16. The insulative material 18 is sized to extend between the second face 24 of the first framing member 14 and the second face 30 of the second framing member 16 and within the cavity 20, as shown in Fig. 2. In some illustrative embodiments, when the insulative material 18 is installed to form the insulated ceiling 10, the third faces 26, 32 of the framing members 14, 16 may not be visible when the insulated ceiling 10 is viewed from below.

[0068] The insulative material 18 extends away from the inward face 12A of the deck 12 a distance D2 as shown in Fig. 2.

[00107] The adhesive layer 338 is generally continuous between the backing layer 34 and the insulative-fiber layer 36, as shown in Figs. 7 and 8. Illustratively, if the backing layer 334 is permeable or the backing layer 334 includes the vent apertures 335, the sections of the backing layer 334 that are not covered with adhesive may allow vapor transfer between the deck 12 and the insulative-fiber layer 336. In some embodiments, the adhesive layer 338 has a width that is narrower than the width W2 of the backing layer 34.

[00108] The insulative material 318 is coupled to the deck 12 with a fastener 40 as shown in Figs. 7-8. The fastener 40 extends from the insulative-fiber layer 336 through the backing layer 334 to the deck 12. In some embodiments, a portion of the insulative-fiber layer 342 is located between the fastener 40 and the backing layer 334 as shown in Figs. 7-8. Illustratively, a first face 344 of the insulative material 18 that faces away from the deck 12 is not deformed visually when the insulative material 318 is fastened to the deck 12. In some embodiments, the fastened insulative material 318 is not appreciably compressed so the performance is maintained. Illustratively, the portion of the insulative-fiber layer 342 located between the crown 50 and the deck 12 has a density that is greater than the density of the insulative material 318 that is not located between the crown 50 and the deck 12.

[00109] Illustratively, when the backing layer 334 is formed to include the vent apertures 335, the vent apertures 335 will extend from the backing layer 334 and open into the insulative-fiber layer 336.

[00110] Illustratively, when the insulative material 318 is coupled to the deck 12 each of the first leg 46 and the second leg 48 extend from the crown 50 through the backing layer 334 into the deck 12. In some embodiments, some fibers of the insulative-fiber layer 336 are fractured by the crown 50 when stapling the insulative material 318 to the deck 12. In some embodiments, the fastener is inserted into the deck 12 on an opposite side of the deck 12 from the insulative material 318.

[00111] Illustratively, the crown 50 locates a portion of the backing layer 334 between the deck 12 and the crown 50. The crown 50 has a width as measured from the first leg 46 to the second leg 48. In some embodiments, the crown 50 may be about 0.25 inches wide. In some embodiments, the crown 50 may be about 0.5 inches wide. In some embodiments, the first leg 46 may be about 0.75 inches long.

In some embodiments, the crown 50 may be about 0.1 inches wide to about 1 inch wide, about 0.2 inches wide to about 1 inch wide, about 0.3 inches to about 1 inch wide, or about 0.4 inches wide to about 1 inch wide. In some embodiments, the crown 50 extends away about 0.1 inches to about 0.3 inches from the deck 12 after fastening the insulative material 18 to the deck 12.

[00112] Illustratively, a first face 344 of the insulative material 18 that faces away from the deck 12 is not deformed visually when the insulative material 18 is fastened to the deck 12. In some embodiments, the fastened insulative material 18 is not appreciably compressed so the performance is maintained. Illustratively, the first face 344 is generally exposed when the insulative material 18 is coupled with the surface 1 1 .

[00113] In some embodiments, insulative material 318 is coupled with deck 12 with a plurality of fasteners 40, as suggested in Figs. 7 and 8. In some embodiments, the insulative material 318 is coupled with the deck 12 with 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10,

1 1 , 12, or 13 fasteners or any other number of suitable fasteners. In an illustrative embodiment, about 6 fasteners are used to fasten the insulative material to the deck

12, as shown in Fig. 14. The fasteners 40 may be inserted so that there are two fasteners 40 located at a first end of the batt of insulative material 318, two fasteners 40 at a second end of the batt of insulative material 318, and two fasteners 40 between the first and second ends of the batt of insulative material, as shown in Fig. 14.

[00114] In another embodiment, an insulated ceiling 410 comprises an insulative material 418 coupled to a surface 1 1 , as shown in Fig. 10. The surface 1 1 of Fig. 10 is similar to the surface 1 1 of Fig. 1 , and the description of the surface 1 1 of Fig. 1 is incorporated herein for the ceiling 410.

[00115] The insulative material 418 includes a backing layer 434, an insulative- fiber layer 436, and an adhesive layer 438, as shown in Figs. 10-1 1 . The insulative- fiber layer 436 is coupled to the backing layer 434 with the adhesive layer 438. The adhesive layer 438 extends between the backing layer 434 and the insulative-fiber layer 436.

[00116] When the insulative material 418 is coupled to the deck 12, the backing layer 434 is located between the insulative-fiber layer 436 and the deck 12 as shown in Figs. 10-1 1 . The backing layer 434 may comprise a polyethylene, a polypropylene, a polyamide, a combination thereof, or any suitable alternative. In some embodiments, the backing layer 434 comprises a metallized foil. In some embodiments, the backing layer 434 comprises a kraft paper. In some embodiments, the backing layer 434 may be a foil-scrim-kraft material. In some embodiments, the backing layer 434 may be a polypropylene-scrim-kraft material. In some embodiments, the backing layer 434 may be a mat face material, a mesh material, or a scrim mat.

[00117] In some embodiments, the backing layer 434 is configured to provide sufficient strength and tear resistance so the insulative material 418 is retained on the deck 12. In some embodiments, the backing layer 434 comprises a reinforcing material. In some embodiments, the reinforcing material comprises fiberglass or any other suitable alternative.

[00118] The backing layer 434 allows the transmission of vapor therethrough. Illustratively, the backing layer 434 may comprise a material that is permeable, include vent apertures 435, expose areas of the insulative-fiber layer 436, a combination thereof, or any suitable alternative. Illustratively, the backing layer 434 may comprise a membrane that is permeable to moisture. An exemplary embodiment of a permeable backing layer 434 is MemBrain™ produced by CertainTeed®. In some embodiments, the backing layer 34 comprises a kraft paper. In some embodiments, the backing layer 434 is pin perforated to form vent apertures 435.

[00119] In some embodiments, the backing layer 434 includes an outer-backing layer, a reinforcement layer, and an inner-backing layer in a similar manner to backing layer 34.

[00120] The adhesive layer 438 extends between and interconnects the insulative-fiber layer 436 and the backing layer 434, as shown in Fig. 1 1 . In some embodiments, the adhesive layer 438 comprises an asphalt adhesive or any suitable alternative. In some embodiments, the adhesive layer 438 comprises a hot melt, a wax, a combination thereof, or any suitable alternative. In some embodiments, the adhesive layer 438 acts as a vapor barrier. In some embodiments, the adhesive layer 438 is has a width that is narrower than the width W2 of the backing layer 434.

[00121] The backing layer 434 can be formed to include vent apertures 435, as shown in Figs. 10-1 1 . Illustratively, the vent apertures 435 extend from the backing layer 434 through the adhesive layer 438, as shown in Fig. 1 1 . In some embodiments, the insulative material 418 is perforated after the insulative fiber layer 436 adheres to the backing layer 434 so that the vent apertures 435 extend from the backing layer 434 and open into the insulative fiber layer 436. Without being bound by theory, it is believed that perforating the backing layer 434 and the adhesive layer 438 will allow vapor to pass between the insulative fiber layer 436 and the deck 12.

[00122] The insulative material 418 is coupled to the deck 12 with a fastener 40 as shown in Figs. 10-1 1 . The fastener 40 extends from the insulative-fiber layer 436 through the backing layer 434 to the deck 12. In some embodiments, a portion of the insulative-fiber layer 442 is located between the fastener 40 and the backing layer 434 as shown in Figs. 10-1 1 . Illustratively, a first face 444 of the insulative material 418 that faces away from the deck 12 is not deformed visually when the insulative material 418 is fastened to the deck 12. In some embodiments, the fastened insulative material 418 is not appreciably compressed so the performance is maintained.

[00123] In another embodiment, an insulated ceiling 210 comprises the surface 1 1 , insulative material 18, and a support bracket 252, as shown in Fig. 12. The insulative material 18 is coupled to the deck 1 1 with a fastener 40 in a similar manner as insulated ceiling 10. The support bracket 252 is coupled with a first framing member 14 to support insulative material 18 as shown in Fig. 12. Illustratively, the support bracket 252 is configured to cooperate with the fasteners 40 to secure the insulative material 18 to the deck 12, as shown in Fig.12.

[00124] The support bracket 252 couples with the framing member 14, 16 and extends towards the first face 44 of the insulative material 18, as shown in Fig. 12. The support bracket 252 includes a framing-member attachment 254, a spacer 256, and a support platform 258 as shown in Fig. 13. The framing-member attachment 254 attaches the support bracket 252 to a framing member 15, 16. The support platform 258 is located in spaced-apart relation to the framing-member attachment 254. The spacer 256 extends between and interconnects the framing-member attachment 254 and the support platform 258.

[00125] The framing-member attachment 254 attaches the support bracket 252 to the framing members 14, 16, as shown in Fig. 12. Illustratively, the framing-member attachment 254 is generally u-shaped and extends around the third face 26, 32 of the framing members 14, 16 and up the first and second faces 22, 24, 28, 30, as shown in Figs. 12 and 13. In some embodiments, the framing-member attachment 254 is configured to receive a fastener 40 therethrough to fasten the framing-member attachment 254 with the framing member 14, 16. In some embodiments, the framing- member attachment 254 is formed to include pins, sometimes called teeth, to couple the framing-member attachment 254 to the framing member 14, 16.

[00126] The support platform 258 is located spaced-apart from the framing- member attachment 254, as shown in Figs. 12 and 13. The support platform 258 is configured to retain the insulative material 18 to the ceiling 210 if the fasteners 40 fail. The support platform 258 includes a first face 258A that faces towards the insulative material 18 and a second face 258B that faces away from the insulative material 18, as shown in Figs.12 and 13.

[00127] The spacer 256 extends between and interconnects the framing-member attachment 254 and the support platform 258, as shown in Fig. 12. The spacer 256 is sized so that the support platform 258 is adjacent to the first face 44 of the insulation. The spacer 256 can be a wire, a rod, a strap, a combination thereof, or any suitable alternative.

[00128] A method 100 of insulating a surface 1 1 is shown, for example, in Fig. 14. In some embodiments, the surface 1 1 is generally horizontal relative to the ground or the floor. In some other embodiments, the surface 1 1 is generally angled relative to the ground or the floor. While this method describes installing insulative material 18, the method equally applies to the other insulative materials 318, 418 described herein. [00129] In some embodiments, the method 100 includes providing a surface 1 1 including the deck 12, the first framing member 14, and the second framing member 16. The first framing member 14 is generally parallel with the second framing member 16. The deck 12 generally overlies each of the first framing member 14 and the second framing member 16 to form a cavity 20 therein. In other embodiments, the surface 1 1 does not include the first framing member 14 or the second framing member 16.

[00130] In some embodiments, the method 100 further includes providing insulative material 18. The insulative material 18 includes the backing layer 34, the adhesive layer 38, and the insulative-fiber layer 36. The backing layer 34 and the insulative-fiber layer 36 are spaced-apart from one another. The adhesive layer 38 extends between and interconnects the insulative-fiber layer 36 and the backing layer 34. While this method describes installing insulative material 18, the method equally applies to the other insulative materials 318, 418 described herein.

[00131] In some embodiments, the method 100 further includes locating the insulative material 18 in the first cavity 20. The step of locating includes orienting the insulative material 18 so the backing layer 34 is located between the deck 12 and the insulative-fiber layer 36. Illustratively, the step of locating the insulative material 18 may be sufficient to hold the insulative material 18 within the first cavity 20. Without being bound by theory, it is believed that in some embodiments there is sufficient friction between the insulative material 18 and the framing members, 14, 15, 16 to hold the insulative material 18 in the cavity 20.

[00132] In some examples of the step of locating can be repeated so that multiple batts of insulative material 18 are located within the cavities prior to proceeding to the next step. In some examples, the step of locating may begin by inserting insulative material 18 along the eave and working up the slope of the deck 12. In some examples, the step of locating may begin by inserting insulative material 18 at the peak of the deck 12 and working down the slope of the deck 12. In some embodiments, the step of locating may begin at any point in the deck 12.

[00133] In some examples, insulation stops are inserted prior to proceeding to the next step. In some examples, insulation stops are inserted prior to the step of locating the insulation. In some examples, the insulation stops are inserted after the step of fastening the insulative material 18. Illustratively, the insulation stops may provide a space so that air may pass through the insulated space. [00134] In some embodiments, the method 100 further includes fastening together the insulative material 18 and the deck 12. The step of fastening uses a fastener 40 that couples the insulative material 18 to the deck 12. The fastener 40 extends from the insulative-fiber layer 36 to the deck 12. In some embodiments, the fastener 40 extends from the insulative-fiber layer 36 through the backing layer 34 and into the deck 12. Illustratively, the step of fastening the fastener 40 may be performed with a pneumatic stapler, a staple gun, or any suitable alternative. Illustratively, the insulative material 18 recovers its original thickness after the step of fastening so that the first face 44 is generally uninterrupted, as shown in Fig. 14.

[00135] In some embodiments, the surface 1 1 further includes a third framing member 15 located spaced-apart from the first framing member 14 to locate the second framing member 16 therebetween. The third framing member 15, the second framing member 16, and the deck 12 cooperate to form a second cavity 21 therein. In some embodiments, the method 100 further includes repeating the steps of providing, the step of locating the insulative material 18 in the second cavity 21 , and the step of fastening the insulative material 18 to the deck 12 in the second cavity 21 to form a continuous insulative material surface that overlies the framing members 14, 15, 16 when the surface is viewed from below.

[00136] In another embodiment, the method 100 further includes coupling the support bracket 252 to a framing member 14, 15, 16. In some embodiments, the step of coupling the support bracket 252 to the framing member is performed after the insulative material 18 is fastened to the deck 12.

[00137] In some embodiments, the mineral wool roll or batt of insulative material (e.g. insulative material 18) that has a reinforced mat/facing laminated to one of the major surfaces (e.g. backing layer 34) may be used. The insulative material (e.g. insulative material 18) may be placed with the facing side (e.g. backing layer 34) upward in a horizontal position toward the roof deck (e.g. deck 12) in an attic or facing upward toward the floor (e.g. deck 12) in a crawl space between the framing members (e.g. first framing member 14 and second framing member 16). A pneumatic staple gun may be used to fasten the underneath side of the mineral wool roll or batt (e.g. insulative material 18) directly through the insulative material (e.g. insulative-fiber layer 36) and reinforced facing (e.g. backing layer 34) into the roof deck (e.g. deck 12) or floor (e.g. deck 12) of the crawl space.

[00138] The staples (e.g. fastener 40) may hold the reinforced facing (e.g.

backing layer 34) tight against the roof deck (e.g. deck 12) or flooring (e.g. deck 12) in the horizontal position and hence the insulative material (e.g. insulative material 18), since the facing (e.g. backing layer 34) is laminated to the insulative material (e.g. insulative-fiber layer 36). This application (e.g. method 100) may decrease the possibility of the insulative material (e.g. insulative material 18) falling since it is mechanically held in place by the staples (e.g. fasteners 40).

[00139] The staples (e.g. fasteners 40) may be installed using an air powered pneumatic staple gun. In some embodiments, the fasteners 40 may exit the staple gun with sufficient force to pierce through the mineral wool insulative material (e.g.

insulative-fiber layer 36) and catch the reinforced facing (e.g. backing layer 34) and pin it against the roof deck (e.g. deck 12) in the attic or a subfloor (e.g. deck 12) in a crawl space. A potential benefit to this type of application may be that the insulative material (e.g. insulative material 18) may not be compressed which would allow for the full thermal performance the insulative material 18 is intended to provide.

[00228] Examples

[00229] Example 1

[00230] The ability of the insulative material 18 to be retained within a cavity 20 with fasteners 40 was measured as described in this example. Briefly, five R19 and five R38 fiberglass batts of insulative material were exposed to a specified frequency, amplitude, and duration of vibration. The vibration conditions are those referenced in Test Method RDS100-3, an accredited test method performed by R&D Services, Inc. Visual observations were made on the batts after vibration, which is described below.

[00231] IDENTIFICATION OF INSULATION TESTED

[00232] The insulative material 18 comprised a foil-scrim-kraft backing layer and bore the product identification of:

R19 FSK Eco Batt - product code 5001864

nominal dimensions 6.25 by 24 by 48 inches manufactured on September 2, 2016; or

R38 FSK Eco Batt - product code 5001778

nominal dimensions 12 by 24 by 48 inches

manufactured on July 2, 2016

[00233] Five specimens of each product were selected from the available lots of material. The specimens were selected by dividing the number of batts of insulative material into five equal sub-lots and selecting one batt from each sub-lot. [00234] EQUIPMENT AND INSTALLATION

[00235] The insulative material used in this example were fastened to a test rack that simulated a 24-inch on-center roof cavity constructed with nominal two by four inch lumber and resembled the insulative material 18 and cavity 20 suggested in Fig. 1 . The insulative material 18 was placed into the cavity 20 so that the backing layer 34 was located between the insulative-fiber layer 36 and the deck 12. In this example, the deck 12 was nominal 7/16 inch oriented strand board (OSB). The cavity 20 was about 48 inches long and open on both ends.

[00236] The test rack was mounted on an Ail-American Tool & Mfg. Co. vibration table, in a horizontal position. The insulative material 18 faced downward.

[00237] The insulative material 18 was fastened with the deck 12 the test cavity 20 using 0.25 inch crown, 0.5 inch leg staples as the fasteners 40. The staples were inserted into the insulative material 18 using a pneumatic staple gun set at 90 lb/in 2 (PSI). All batts of insulative material 18 were mounted with six staples. Four of the staples were placed six inches inside and six inches down from each corner. Two of the staples were placed 18 inches from each lengthwise edge of the cavity 20, on the center line of the cavity 20.

[00238] For the insulative material 18 rated R19, the staple gun trigger was pressed prior to pushing the staple gun into the insulative-fiber layer 36. For the insulative material rated R38, the staple gun was pushed into the insulative-fiber layer prior to the trigger being pressed. These methods allowed for some fiberglass insulative fibers to be "pinched" between the crown of the staple and the deck 12 to form the portion of the insulative fiber 42.

[00239] VIBRATION PROTOCOL

[00240] The specified vibration protocol for this project was taken from Test Method RDS100-03 "Method for Determining the Resistance to Settling of Thermal Insulation Installed in Wall Cavities." The conditions of this method are shown below in Table 1

[00241] Table 1 : Vibration Protocol

[00242] It is estimated that this set of conditions simulates the approximate kinetic energy that a residential structure will transmit to cavity insulation in a 24-year period. [00243] TEST RESULTS

[00244] Each piece of the insulative material 18 was examined visually prior to vibration for obvious defects. Initial dimensions and mass measurements were recorded for each batt of insulative material 18. These measurements, and the calculated density, of each batt are listed in Table 2.

[00245] Table 2: Dimensions and Density of Test Specimens

[00246] During the vibration protocol, one batt of insulative material 18 rated R19 fell out of the cavity 20 prior to the end of the 24-hour vibration period. One batt of insulative material 18 rated R38 partially delaminated during vibration the vibration protocol.
