Production and Drying
Treatment of FRX® wood is performed at properly equipped and supervised treatment plants in strict accordance with industry standards. Following treatment, FRX wood is re-dried to a moisture content of 19% or less for lumber and 15% or less for plywood in accordance with Appendix H of the AWPA Use Category System and past AWPA standards C20 for lumber and C27 for plywood. Drying after treatment is required to comply with the model building codes.
Third-Party Inspection
Comprehensive QC 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.
