Abstract:

A test protocol based on the Intermediate Scale Heat Release Calorimeter (ICAL) was used to evaluate the potential fire retardant effects of two water-based durable agents applied to wood, to plastic (vinyl) siding and to small windows mounted into wood siding. The protocol included exposure of one meter square specimens to constant heat fluxes of 15 and 25 kW/m2 in the presence of an open-flame ignition source. Wood panels treated with the fire-retarding gel were compared to untreated panels and to panels treated only with water. Time delay to ignition of the specimen was the primary measured property, while mass changes prior to and during the fire exposure were recorded. The gel treatments extended the times to ignition of painted wood siding from around 30 seconds for untreated panels to more than 300 seconds of exposure at 25 kW/m2. Drying the treated panels at 1 kW/m2 for an hour generally did not significantly affect the performance of treated panels with respect to times to ignition.
