Rate of Heat Release from Wood-Base Building Materials Exposed to Fire.
Abstract
Data on the 'potential total heat release' or on the 'rate of heat release' has been suggested as means of defining combustibility of materials in building code regulations, and would replace the present 'noncombustibility' requirements. Rate of heat release data on several types of wood-base materials and constructions were determined under fire exposure in an FPL (Forest Products Laboratory) developed, gas-fired, water-jacketed furnace. Materials evaluated include Douglas-fir plywood (untreated and fire retardant treated), high-density hardboard, red oak lumber, rigid insulation board, and particleboard. Among the constructions were a plywood-faced polyurethane foam sandwich panel and assemblies of both fire-retardant-treated and untreated Douglas-fir studs and gypsum wallboard facings. The results indicate that fire-retardant treatment of wood greatly reduced the maximum rate of heat release. This work provides both a potentially useful Measurement of combustibility and additional information on fire performance of wood-base building materials.
