ABSTRACT:
A heat insulation panel is adapted to be mounted in a window frame and includes a pair of spaced substantially flat face sheets connected by a plurality of connector strips extending therebetween. The peripheral edge of the panel is sealed by a gusset strip in air tight relation. The gusset strip has a firmer hand than the face sheets and is approximately 25% heavier in gauge so that upon inflation the edge of the panel remains substantially flat in order to form a broad substantially air tight seal with the periphery of a window frame in which the panel is inserted. The gusset edge also can cooperate with the edge of an adjacent panel to form a substantially air tight seal therebetween.
