Abstract
Abstract A fire retardant, weight-bearing building panel having a frame enclosing fiberglass insulating material which is press-fitted between a pair of aluminum-plywood bonded sheet faces. The plywood is treated with a solution to render it substantially non-combustible. Added fire resistance is obtained by including one or two sheets of gypsum board between the outer wood sheets.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
153 words
A fire retardant insulated building wall comprising: a. a plurality of modular panels each including: 1. framing means for supporting a plurality of sheet materials; 2. fiberglass insulating material within said framing means; 3. plywood sheets positioned transversely on each side of said framing means for fully enclosing said fiberglass material adjacent the interior surfaces thereof, said plywood sheets being treated with a solution for rendering them substantially non-combustible; 4. metal bonded to the exterior surface of said plywood sheets; and 5. at least one pair of interior bracing sections separated from one another to prevent heat conduction through the modular panel; b. said plurality of panels being secured together by attaching means, and covered access openings on at least one side of the panel to provide access to the attaching means joining said panels together; and c. expansion materials between adjacent panels and a sealing trim material over the line of juncture.
