** NOTE TO SPECIFIER ** D-Blaze Fire Retardant Treated (FRT) lumber and plywood is highly effective against the spread of flame and smoke. D-Blaze is UL classified with an FR-S rating, indicating a flame-spread index and smoke rating index of 25 or less when subjected to ASTM E 84 tests of 30 minutes duration without evidence of significant combustion. D-Blaze FRT materials are independently tested. They qualify with all major building codes and insurance rating bureaus. They are easy to handle and workable with common tools. In most cases, they feature a lower in-place cost than noncombustible classified materials. Lumber and plywood treated with D-Blaze fire retardant can be used in a variety of interior applications where the humidity is not expected to exceed 95% for prolonged periods and where the wood is not directly exposed to weather. D-Blaze fire retardant treated wood is available for interior applications where fire retardant construction materials are specified.
