Fire Retardant Plywood Euro Class B (2440mm x 1220mm) – All Sizes

Fire retardant plywood is specially treated with chemicals that act as a physical barrier to fire. Sentrin fire retardent treated wood products are pressure impregnated with Sentrin FRI, a humidity resistant interior grade, high temperature fire retardant chemical formulation.

The sheet material works by utilizing two mechanisms. One of them is reducing the flammability of fire-resistant plywood by lowering the rate at which flames travel and subsequently slowing down combustion. The second mechanism involves the chemicals reducing the rate at which heat is released from the fire-treated plywood when there’s a fire. By altering the vapours released in the combustion process, it can make the flames less volatile.
