D-Blaze® fire retardant treated wood (FRTW) is available for interior applications where fire retardant construction materials are required by building codes. D-Blaze® treated lumber and plywood is highly effective in controlling the spread of flame and smoke caused by fire.

D-Blaze® treated products show no evidence of significant progressive combustion at 30 minutes exposure to flame. In most applications, D-Blaze® treated products offer a lower in-place cost than noncombustible classified materials.
