Dricon® Fire Retardant



Whether you are using plywood or timber, Dricon® Fire Retardant Treated (FRT) wood has an unmatched record of protection against flame spread, smoke development, rot and decay.

Dricon® , introduced to the US market in 1981, is a Class A fire retardant (as per ASTM E84 test method) and preservative intended for wood used in interior, weather-protected construction. Dricon® is applied by standard pressure treatment process creating a built-in protection from both flame spread and smoke development that does not require maintenance. After treatment the wood should be carefully kiln dried back to construction timber moisture content levels.

When exposed to fire, Dricon® automatically reacts with the combustible gases and tars normally generated by untreated wood, converting them to carbon char, with carbon dioxide and water. The surface char acts to insulate underlying wood, and the carbon dioxide and water vapour dilute the combustible gases to help reduce flame spread and smoke.

The only US-EPA registered fire retardant on the market, Dricon® also contains a preservative component that prevents damage caused by termites and fungal decay, offering an extra level of peace of mind.
