The Guardian in the Grain: How Fire Retardant Treated Wood Enhances Safety
Fire Retardant Treated Wood (FRTW) is a vital engineered building material designed to provide a critical line of defense against the spread of fire. Unlike regular lumber, FRTW undergoes a specialized pressure-impregnation process where fire-retardant chemicals are deeply embedded into the wood cells. These chemicals do not make the wood fireproof, but they significantly alter its performance when exposed to flames.
