— Who We Are
A FIRE RETARDANT TREATED WOOD SUPPLIER BUILT TO PERFORM.
Since 1991, Flameproof Companies has manufactured fire retardant and preservative treated wood products built to perform when it matters most. What started as a small treatment facility in Chicago has grown into a nationwide operation, with manufacturing and distribution facilities in Illinois, Wisconsin, Texas, and Virginia.
Today we specialize in high-performance treated lumber, plywood, OSB, and engineered wood products, supplying reliable, code-compliant solutions for demanding commercial, industrial, and code-driven construction projects across the country.
We've operated through decades of evolving fire safety standards, building codes, and regulatory shifts. That longevity isn't nostalgia. It's evidence: proof that we understand specifications, documentation, and compliance from the start of a project through inspection.
THREE REASONS BUYERS CHOOSE US.
— Why Flameproof
We don't just sell fire treated materials. We sell certainty. Three things separate us from transactional lumber suppliers.
Legacy & Compliance
Expertise, proven over decades
Founded in 1991, we've worked within the fire retardant treated wood category through every major code cycle. When contractors, builders, and distributors work with us, they get a partner that understands specifications, documentation, and compliance requirements, reducing the financial and scheduling risk of a failed inspection.
Direct Access
No queues. No call centers.
Construction moves fast and rarely on schedule. Instead of automated systems and ticket queues, you work directly with experienced team members accountable for your project, whether it's reviewing specs, sourcing materials, or responding to a schedule change.
Supply Reliability
Capacity that keeps you moving
In a market shaped by mill closures and supply disruptions, dependable capacity is critical. Our four manufacturing and distribution facilities let us produce and supply treated lumber with competitive lead times, so material delays don't ripple across your entire timeline.
FOUR FACILITIES. COAST TO INTERIOR.
