How Biewer’s Fire Treated Wood Stands Out
When you’re building projects where safety is non-negotiable — like multifamily housing, schools, or commercial buildings — fire treated wood is often a code requirement. But not all fire treated wood is the same. Choosing the right product can mean fewer headaches during construction, easier inspections, and peace of mind for everyone involved.
At Biewer FRTW, we take pride in delivering the best fire treated wood available — and we back it up with proven performance, reliable supply, and support you can trust.
What Makes Biewer FRTW Different
✅ Fully Code-Compliant
Every stick of Biewer FRTW meets the requirements of the International Building Code (IBC) and International Residential Code (IRC). Our fire treated wood carries a Class A flame spread rating (ASTM E84) — the highest rating available — meaning it significantly slows the spread of flames and smoke in a fire situation.
✅ Dimensionally Stable & Easy to Work With
Our lumber is kiln-dried after treatment (KDAT), which locks in the treatment, lowers moisture content, and reduces warping, shrinking, and twisting on the job site. That means fewer callbacks, less rework, and a better-looking finished product.
✅ Available When You Need It
Biewer’s network of strategically located treatment facilities ensures reliable availability across the Midwest and beyond. Whether you need 2x framing lumber, plywood, or specialty sizes, we’ve got you covered — so your project stays on schedule.
✅ Backed by Expert Support
Our technical team is available to help with submittals, code questions, and specification needs. We make sure you have everything you need to satisfy inspectors and keep your project moving forward.
✅ Safe & Sustainable
We use non-corrosive fire-retardant formulations that are safe for your crew to handle with standard PPE and maintain the wood’s natural strength. Plus, we source from responsibly managed forests to support sustainable building practices.
The Bottom Line
When it comes to fire treated wood, performance and reliability matter. Biewer FRTW gives you the confidence that your project meets code, your materials will perform, and your job will stay on track.
