ABSTRACT:
A fireproof panel for closing structural openings within building structures such as those between rooms, floors, ceilings, and the like through which essential-service hardware such as ducts, pipes, electrical conduit, and the like penetrates, or for providing support for such hardware. The panel comprises a solid matrix of refractory material having reinforcement material embedded therein. Preferably, the reinforcement material is embedded immediately beneath essentially all of at least one of the panel's front and back exterior surfaces. A preferred reinforcement material is a fiberglass material, preferably embedded immediately beneath both the front and back exterior surfaces of the panel. The reinforcement material inhibits fracture of the panel to thereby provide a greater workability in panel installation. The panel can be flat or shaped in accord with its intended function, and openings therethrough to accommodate penetrating hardware can be readily made.
