Benefits of Pyro-Guard Interior Fire Retardant Treated Wood

Increased Fire Performance without Additional Smoke Toxicity

Pyro-Guard is pressure impregnated deep into the wood to provide permanent protection, unlike coatings, which only provide superficial protection.

When Pyro-Guard treated wood is exposed to fire, non-combustible gas and water vapor are produced, and a layer of protective char forms, which hinders combustion and insulates the wood against further damage.

Pyro-Guard interior fire-retardant treated wood has a low rate of fuel contribution and heat release, and it maintains structural integrity longer than other building materials such as steel. Consequently, fire damages and repair costs are minimized, resulting in reduced insurance rates.

When it comes to smoke toxicity, Pyro-Guard has successfully passed a stringent combustion toxicity test. Smoke produced by Pyro-Guard treated wood was no more toxic than smoke produced by untreated wood.

Code Compliance

Pyro-Guard was the first FRTW (fire-retardant treated wood) to be issued a Code Compliance Report based on high temperature testing for roof sheathing and framing uses.

Strength Tested for Structural Applications

Pyro-Guard was the first interior fire-retardant treatment with plywood roof span ratings and lumber strength adjustments based on high temperature testing. Plywood was strength-tested after exposure to 170 degrees F, and lumber was strength-tested after exposure to 150 degrees F according to ASTM 5516 and ASTM 5664. As a result, Pyro-Guard can be used with confidence in all recommended structural applications, including plywood roof sheathing and roof trusses.

Resistant to Decay and Termites

Treatment with Pyro-Guard provides excellent resistance to decay and termites.
