As the industry innovator in fire retardant technology, our FX LumberGuard XT offers a dual-treatment system that was designed to add both long term rot protection combined with Class-A Fire protection for use in decking applications and much more.
Guided by precise quality-control measures, the non-invasive factory-application process harnesses new age manufacturing technology combined with prescriptive chemical formulations that, in addition to adding fire protection, FX LumberGuard protects critical engineering and strength values of these highly-specified products.
