Untreated lumber is placed in a chemical bath under high pressure, allowing for the chemicals to soak deeply into the wood. This results in wood that’s impregnated with fire-resistant chemicals.A durable and leach resistant Class A fire retardant, FRX® treatment reduces flame spread and smoke development in exposed structures. Wood pressure treated with FRX® fire retardant is code-compliant and has been issued an evaluation report (ESR-1159) by International Code Council (ICC) Evaluation Services.Fire retardant wood products are typically created through the use of organic and inorganic salts, which are infused into the wood through water-based solutions under pressure. The end result is a product that has 2.5 to 5.0 pounds of salts per cubic foot of wood product.
