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.

D-Blaze is recognized as a code compliant pressure-impregnated fire-retardant treatment under the International Building Code® (IBC®), International Residential Code® (IRC®) and the National Building Code of Canada® (NBC®) for lumber and plywood products used in fire rated assemblies and interior applications where fire retardant construction materials are permitted and specified by the building codes.

Acceptable for use in sensitive environments such as schools, healthcare facilities, hotels and multi-family construction projects, D-Blaze received GREENGUARD® Gold certification for meeting some of the world’s most comprehensive standards for low emissions of volatile organic compounds (VOCs) into indoor air.

Backed by a 50-Year Limited Warranty, D-Blaze FRTW is protected against structural failure due to strength loss caused by high temperature and high humidity conditions. (See Warranty for details.)

D-Blaze FRTW products are fire resistant, durable, non-hygroscopic, non-blooming, easy to handle, workable with common woodworking tools, and offers a lower in-place cost than materials classified as non-combustible. D-Blaze FRTW has been used in projects across North America, including the One Word Trade Center in New York City and Navy Pier in Chicago.
