Pyro-Guard® is pressure-impregnated, kiln-dried after treatment fire-retardant lumber and plywood for interior structural applications.
Pyro-Guard® lumber and plywood is UL listed and produced in accordance with quality control procedures mandated by the International Code Counsel Evaluation Service (ICC-ES).
When Pyro-Guard® wood is exposed to fire, water and non-combustible gas will form, as well as a layer of heatproof char, which prevents combustion and insulates the wood from further damage.
