ABSTRACT:
Bladder insulation which is adapted to be inserted within the wall cavities of existing buildings is disclosed which provides for high quality insulation having a high R value. The invention describes a bladder or impervious bag constructed of two thermoplastic sheets of material hermetically sealed at both ends and on each of the sides. The preferred film used herein is urethane although polyethylene of from 4 to 15 mils in thickness may be employed on the inside and/or the outside of the bladder. This bag can be inflated within the wall cavity and filled with various insulative materials and/or pressurized with various fluorinated hydrocarbon gases. The various insulative fill materials used may be, but to be all not inclusive, vermiculite, mineral wool, microballoons of either glass or plastic, and eggcrates, or any combinations of these materials. An expandable eggcrate device constructed of thermoplastic material in a collapsed state and sandwiched between two layers of thermoplastic material that expands into an eggcrate when inflated creates a semi-rigid plastic material. The gaseous medium used in this invention consists preferably of fluorinated hydrocarbon gas, CO.sub.2 or N.sub.2, and has a pressure of up to one and one-half pounds, or a vacuum of 16 to 18 inches of water, which is about 0.65 pounds vacuum, or about 0.05 atmospheres.
The invention also includes a means for inserting the bladder with the wall of a structure and rigidifying the bladder by adherence to studs or a polymerization technique to form a polyisocyanate on the interior side of the bladder.
