ABSTRACT:
This invention relates to energy conserving structural elements, commonly called window or door frames with outer framing being adapted to be installed in building wall rough openings, said framing has a strip of compressible expandable thermal insulation fastened in a recess in said framing and an enveloping means maintains said thermal insulation in a compressed state until said structural element is installed in said building wall, said enveloping means is of tearable material that can be rendered inoperative allowing said thermal insulation to expand and fill said air gap, reducing heat transfer either direction through said air gap.
This invention relates to all objects constructed to be inserted into other objects creating an air gap that should be sealed and thermally insulated.
