As wildfire risks continue to rise and building codes tighten across the country, especially in Wildland Urban Interface (WUI) zones fire performance has become a top priority for decking materials in 2026.
Homeowners and builders are looking for decking that not only looks beautiful and performs durably but also meets stringent fire safety standards. Trex, the leader in wood alternative decking, has responded with important updates to its fire rated offerings.
Understanding Fire Ratings for Decking
Fire ratings for exterior decking typically reference standards like ASTM E84 for flame spread.
- Class A represents the highest rating, indicating the lowest flame spread and best performance in resisting ignition and slowing fire.
- Many traditional composites, including earlier Trex lines, achieve solid Class B ratings better than natural wood (often Class C) but fall short of the strictest WUI and IWUIC (International Wildland Urban Interface Code) requirements in high risk areas. Many areas do allow for the use of Class B materials so make sure you check your local building codes before ordering your deck boards.
For 2026 and beyond, compliance with these codes is essential in many jurisdictions, particularly on the West Coast and in expanding fire prone regions nationwide.
Trex Refuge™: New PVC Decking with Class A Fire Rating
To meet growing demand for superior fire performance, Trex has introduced Refuge™, its first 100% cellular PVC decking line. This expansion allows Trex to offer a true Class A Flame Spread rated decking product while maintaining the brand’s reputation for beauty, durability, and low maintenance.
Key Fire Performance Highlights of Trex Refuge:
- Class A Flame Spread Rating (ASTM E84): Among the highest fire performance levels for exterior decking.
- IWUIC Compliant and WUI approved: Meets ignition resistance requirements for high risk areas.
- Engineered to resist ignition and slow flame spread, providing critical protection against embers and wildfire exposure.
Refuge PVC decking is independently tested and designed specifically for fire prone environments without compromising on aesthetics or performance. It comes in two sophisticated, West Coast inspired colors: Martis Valley (warm, natural mountain tone) and Point Reyes (cool, coastal elegance). Boards are available in 16-ft and 20-ft lengths with a refined, wire brushed grain pattern that mimics real wood.
Why PVC? Additional Benefits Beyond Fire Safety
As a 100% cellular PVC product (no wood fibers), Trex Refuge offers:
- Exceptional resistance to moisture, rot, cracking, splintering, mold, and mildew.
- Minimal maintenance: No staining, sealing, or painting required.
- A 50 year limited residential warranty.
- Solid profile boards that install like traditional wood using deck screws.
This makes it an ideal choice not just for fire safety but for long term value in any climate.
Trex’s Broader Fire Resistant Lineup in 2026
While Refuge delivers the top tier Class A performance, many Trex composite collections (like Transcend, Signature, and Select) continue to provide excellent class B fire resistance suitable for less stringent areas. Trex continues refining its composites alongside this PVC innovation.
