Pyro-Guard is pressure-impregnated, interior fire-retardant treated lumber and plywood for enclosed structural applications.
Pyro-Guard is recommended for enclosed structural applications such as:Plywood roof sheathing
Pyro-Guard has been strength-tested after prolonged exposure to elevated temperatures and moisture to verify its strength characteristics when used in roof systems and other recommended applications.
Pyro-Guard plywood span ratings and lumber design value adjustments are based on strength testing after prolonged exposure to high temperatures experienced in roof applications.
Pyro-Guard is used for interior structural applications such as ceiling and floor joists.
