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.

D-Blaze® fire-retardant treated wood (FRTW) is highly effective at controlling the spread of flame and smoke, increasing evacuation time and potentially reducing damages and repair costs caused by fire. D-Blaze FRTW slows the combustion cycle of fire by forming a protective layer of char, hindering flame spread and smoke formation.

Tested and listed by Underwriters Laboratories® (UL® and ULC®), D-Blaze FRTW meets the requirements of construction materials as set forth in all North American building codes. During the code required 30-minute flame and smoke test; UL 723 (ASTM E84), D-Blaze FRTW shows no evidence of significant progressive combustion.

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.
