A thermal barrier is provided that includes a pair of sheets made of a material such as suitable plastic, and wherein the pair of sheets interfit to form a hollow panel. Compressible cellular foam material is mounted on the outer edges of the panel. Ambient air is adapted to be removed from the interior of the panel, and dry air or inert gas is adapted to be introduced into the hollow panel. Angle clips are provided for helping to maintain the barrier in its proper assembled position.

1. A thermal barrier comprising a dual plastic pane sealed air unit which does not require a separate frame, said barrier adapted to be installed on the inside of an existing window opening and mounting within the existing jamb, head, and sill on the inside of the existing window which remains in place, said barrier comprising a pair of rectangular sheets each having cut away corners, edge portions of said sheets being folded at 90 degrees relative to the main portion of the sheets to provide a pair of pan like members, said pan like members being interfitted together to form a hollow box-like member, foam pieces mounted around the periphery of the box-like member, means for withdrawing ambient air from the interior of the box-like member, and means for introducing dry air, inert gas, and the like into the interior of the member, retaining means mounted adjacent to said thermal barrier. 2. The structure as defined in claim 1 wherein the retaining means comprises lower angle clips arranged adjacent to the thermal barrier, and upper angle clips spaced slightly away from the thermal barrier. 3. The structure as defined in claim 2 wherein the thermal barrier is spaced away from said existing window. 4. A method of making a thermal barrier comprising the steps of providing a pair of rectangular sheets of plastic material, cutting away corner portions of each of the sheets, next bending and folding edge portions of the sheets at a 90 degree angle with respect to the main body portions of the sheets to provide a pair of pan members next, interfitting the pan members together to form a hollow, closed panel, and then withdrawing ambient air from the interior of the panel and introducing dry air, inert gas, and the like into the hollow interior of the panel to provide a thermal barrier for use with the existing windows. 5. In a thermal barrier for use with windows including a head jamb and sill and existing wall and opening, said thermal barrier comprising a dual plastic sealed air unit that does not require a separate frame, said barrier being designed for installation on the inside of an existing window opening and which mounts within the existing jamb, head, and sill of the inside of the existing window which remains in place, said barrier consisting of a pair of rectangular sheets of plastic, each of said sheets having all four corners cut to provide notches, the edge portions of said sheets being bent and folded at 90 degrees to form a pair of flat pan members, one of said pan members being slightly larger than the other pan member, and wherein the pan members are interfitted with each other, cement in the corners of the pans, compressible foam pieces secured to the outer periphery of the panel formed by the interfitting pan members, means for removing ambient air from the interior of the barrier, means for introducing dry air, inert gas, and the like into the interior of the barrier, and clip means adjacent to said barrier. 6. The structure as defined in claim 5 wherein said clip means comprise lower clips at the corners of the barrier which are contiguous to the barrier, and upper clips which are spaced slightly away from the barrier, and wherein the upper clips are disposed inwardly from the upper corners of said barrier. 7. The structure as defined in claim 6 wherein there is provided a space between the barrier and the existing windows. 8. In a barrier for use in an opening without an existing window, said barrier comprising a pair of rectangular sheets of plastic, each of said sheets having all four corners cut to provide notches, the edge portions of said sheets being bent and folded at 90 degrees to form a pair of flat pan members, one of said pan members being slightly larger than the other pan member, and wherein the pan members are interfitted with each other, cement in the corners of the pans, compressible foam pieces secured to the outer periphery of the panel formed by the interfitting pan members, means for removing ambient air from the interior of the barrier, means for introducing dry air, inert gas, and the like into the interior of the barrier, and clip means adjacent to said barrier. 9. The structure as defined in claim 8 wherein said clip means embody lower clips at the corners of the barrier which are contiguous to the barrier, and upper clips which are spaced slightly away from said barrier, and wherein the upper clips are disposed inwardly from the upper corners of the barrier. 10. A thermal barrier for use with windows embodying a head jamb and sill, and existing wall and window opening, said thermal barrier adapted to save up to 70% of the energy loss and gain through the window opening, said thermal barrier being installed on the inside of existing windows, said thermal barrier being easily installed, removed and cleaned, and being capable of structurally spanning large areas, said barrier reducing condensation on an existing window and the barrier allowing for expansion and contraction, said thermal barrier including a dual plastic sealed air unit that does not require a separate frame, said barrier being constructed for installation on the inside of an existing window opening and which mounts within the existing jamb head and sill of the inside of the existing window which remains in place, the barrier including a pair of rectangular sheets of transparent plastic, each of said sheets having all four corners cut to provide notches, the edge portions of said sheets being bent and folded at 90 degrees to form a pair of flat pan members, one of said pan members being slightly larger than the other pan member and wherein the pan members are interfitted and cemented with each other, cement in the corners of the pans, clip means adjacent to said barrier, said clip means comprising lower clips at the corners of the barrier which are contiguous to the barrier, and upper clips which are spaced slightly away from the barrier, and upper clips being disposed inwardly from the upper corners of said barrier, there being a space between the barrier and the existing window, and said thermal barrier reducing sound transmission through the window opening.
