There are over 1.5 million structural fires on average per year in the United States.  A structure can be totally consumed in flames within seconds.  Seconds can save lives in a fire and Fire Retardant Treated Wood can give you those extra seconds to get your family to safety.  Fire Retardant Treated Wood is highly effective in controlling the combustibility of the wood, the spread of flame and it reduces the smoke development caused by fire.

Pyro-Guard is a fire retardant wood treatment that is impregnated into framing lumber and plywood products by pressure process to reduce combustibility and smoke development, and is suitable for fire rated wall assemblies and interior applications where fire retardant construction materials are specified or required by building codes.

Exterior Fire-X is pressure-impregnated fire-retardant lumber and plywood that provides tested fire protection for applications directly exposed to the weather or high humidity, outdoors as well as indoors.
