Underwriters Laboratories tested and classified.

D-Blaze® Fire Retardant Treated (FRT) wood is a new generation construction material for weather-protected applications. Its extremely low hygroscopic and corrosive properties make it a superior choice for use whenever FRT wood is required.

D-Blaze® FRT wood is non-blooming and colorless. It qualifies for us in accordance with major building codes and insurance rating bureaus.

Wood treated with D-Blaze® is paintable, stainable, easy to handle and workable with common tools. In most cases, FRT wood systems have lower in-place costs than other noncombustible-classified materials.

UL-CLASSIFIED

D-Blaze® FRT wood has been tested by Underwriters Laboratories, Inc. (UL) of Northbrook, Illinois, and has been awarded the UL classification of “FRS”, which signifies a 25 or less rating for flame spread and smoke development. When tested for 30 minutes’ duration, there was no evidence of significant progressive combustion. Each piece of treated material bears an easily identifiable UL stamp.

Wood treated with this new, scientific formulation solves many of the problems encountered with earlier-generation fire retardant formulas, notably hygroscopicity. D-Blaze® FRT wood remains non-hygroscopic even under conditions of up to 95% relative humidity.

It meets or exceeds the hygroscopic requirements of AWPA C-20, C-27 Type A. In tests conducted in accordance with ASTM D-3201 at relative humidity up to 95%, it has virtually the same moisture content as untreated wood.

D-BLAZE® FRT wood protects against corrosion on galvanized steel truss plates as well as other metal fasteners. Extensive testing has shown that with respect to metal corrosion, D-Blaze® FRT wood maintains metal finish and metal integrity virtually as well as untreated wood exposed to the same conditions.

D-Blaze® FRT wood has been tested by an independent laboratory in accordance with industry standards to develop strength reduction factors for various use conditions including roof temperatures of up to 150 degrees and 170 degrees F.

D-Blaze® interior FRT plywood has been tested and shown to meet the following plywood roof sheathing and subfloor spans when used with span rated plywood and/or plywood bearing the trademark of an approved inspection agency.
