interior side of existing windows

FIELD OF THE INVENTION [001] The present invention relates generally to windows but more particularly to a high density acrylic polymer for use on the interior side of existing windows.

BACKGROUND OF THE INVENTION

[002] With constant search for improved energy efficiency, windows appear to be the culprit, even though many advances have been made to improve their insulating capabilities.

SUMMARY OF THE INVENTION

[003] In view of the foregoing disadvantages inherent in the known devices now present in the prior art, the present invention, which will be described subsequently in greater detail, is to provide objects and advantages which are:

[004] To provide for high density acrylic polymer for use on the interior side of existing windows. [005] In order to do so, the invention comprises a high density acrylic polymer for use on the interior side of existing windows which has at least one pane of clear high density acrylic polymer, and a frame member consisting of strips of high density elastomer so as to minimize heat transfer.

[006] In a preferred embodiment, the frame member is made out of silicone.

[007] In yet another embodiment, the at least one pane of clear high density acrylic polymer consists of two or more panes of clear high density acrylic polymer.

DETAILED DESCRIPTION

[0011] A high density polymer window addition (10) for placement on the interior side of an existing window casing (20) has at least one pane (14) of clear high density polymer such as acrylic, for example, and has a frame member (16) consisting of strips (18) of high density elastomer, such as silicone, for example so as to minimize heat transfer. This frame member (16) is particularly well suited for separating and holding two or more panes (14). By placing this window addition (10) on the interior side of an existing window frame or casing (20), additional insulation is available on old or new constructions. Since acrylic is more transparent ti visible light than glass while at the same time cutting more of the UV frequencies, it causes imperceptible light loss.
