Fire-Retardant

When fire safety is a priority, ProWood Fire-Retardant (FR) pressure-treated lumber delivers superior protection. Our advanced treatment process chemically transforms wood to slow flame spread and reduce smoke development, making it the go-to choice for builders who need code-compliant, fire-resistant materials.

Backed by a 50-year limited warranty and UL-approved, ProWood FR lumber meets and exceeds all major building codes, offering unmatched safety, resilience, and reliability.

How ProWood Fire-Retardant Treatment Works

Our proprietary fire-retardant formula is pressure-infused into the wood, fundamentally changing its chemistry to reduce combustibility. When exposed to heat, the treated wood:

• Releases water and carbon dioxide, cooling the wood and slowing combustion.
• Forms a protective char layer, reducing flame spread and smoke production.
•  Maintains structural integrity, even under extreme temperatures.

This cutting-edge technology is designed to meet the strictest fire safety requirements while preserving the wood’s strength and stability.
