Relentless standards for the ultimate in fire protection.
If you specify fire-retardant dimensional lumber, plywood and wall assemblies for multifamily and commercial structures or for custom homes, look to ProWood FR. It’s superior, fire-retardant wood that pros and specifiers trust. View the architectural specifications.
ProWood FR pressure-treated wood is code compliant and UL approved — its fire-retardant chemical is infused deep into the wood cells, not just the surface. This changes the chemistry of the wood, so when it heats up, it gives off water and carbon dioxide, which helps stop the spread of flames and fire growth.
We're confident ProWood FR will perform, and that's why it's backed with a 50-year limited warranty.
ProWood FR lumber and plywood products are clearly identified. Each piece is stamped with the critical information required by building code authorities, including the UL FR-S designation and the ICC-ES report ESR-4373. Additionally, all ProWood FR products are color tinted for easy identification on the jobsite.
