Wood Treated Right

FRX® fire retardant treated (FRT) wood reduces flame spread and smoke development for applications directly exposed to the weather, including exterior decks, balconies, stairways, canopies, siding, molding, trim and many others. FRX wood meets the requirements of the model building codes for exterior FRT wood and has been issues an evaluation report (PDF) by International Code Council (ICC) Evaluation Services. FRX wood is also listed as a Qualified Product by the U.S. Navy (MIL-L-1914OE).

A Class A (formerly class I) fire retardant having a flame spread index of 25 or less, FRX wood may be substituted for materials classified as non-combustible in certain building types designated by the model building codes and requiring ASTM D 2898 conformance.

FRX wood combines the beauty and versatility of wood with the fire safety of non-combustible materials. Comprehensive quality control programs, conducted by third-party agencies, provide assurance that both the FRX® fire retardant chemical and FRX wood are consistently produced to meet performance standards dictated by the model building codes.
