fire-resistant wood
Flame-retardant timber material
Fire-resistant wood is lumber that has been chemically treated or naturally possesses properties that slow combustion and resist ignition.
The treatment typically involves pressure-impregnating the wood with fire-retardant chemicals.
Unlike fireproof materials, fire-resistant wood will eventually burn under sustained heat, but it chars more slowly and is less likely to spread flames: Building codes require fire-resistant wood for the deck attached to the house.
