EFFECT OF PANEL THICKNESS AND NONCOMBUSTIBLE INSERTS ON SURFACE FLAMMABILITY OF PLYWOOD.

Abstract

Douglas-fir plywood in 1/4- to 1-inch thicknesses was evaluated for flame-spread resistance in the 8-foot tunnel furnace test, corner-wall test, and mild Schlyter test. Under these methods no signficant effect on flame-spread resistance was obtained by varying panel thickness. Work with noncombustible inserts showed that 1/32-inch asbestos or aluminum sheets employed with thin face veneers in panel constructions could significantly reduce surface flammability. (Author)
