FirePRO® brand fire retardant treated wood (FRTW) is lumber and plywood pressure impregnated with FirePRO Interior Type A High Temperature (HT) fire retardant chemicals. FirePRO® brand fire retardant is a patented formulation based on proprietary Osmose technology.
Historically, fire retardants have depended upon phosphorus-based compounds to achieve fire performance properties. While the unique FirePRO® chemistry contains no phosphates, independent testing performed in accordance with industry standards has shown FirePRO® FRTW to exhibit exceptional fire performance properties without compromising other critical engineering properties such as strength, durability, corrosivity, and hygroscopicity. In fact, when compared to the untreated wood used in these tests, FirePRO® FRTW exhibited superior strength durability, low hygroscopicity, and resistance to fastener corrosion.
