Understanding Fire Classifications

CLASS A FLAME SPREAD RATING

Class A is the best rating, signifying a material with the highest resistance to flames. No other leading composite manufacturer has decking with a Class A Flame Spread Rating.

IGNITION RESISTANT

Ignition-resistant decking is less likely to catch fire compared to traditional and composite decking materials.

WUI COMPLIANT

TimberTech Advanced PVC Decking collections — and select Composite Decking collections — meet WUI (Wildland Urban Interface) Compliance standards, ensuring adherence to zoning regulations.

Value That Lasts

When constructing in fire-prone regions, every specification decision matters — and whether you’re a lumberyard or a professional builder, you understand the critical importance of incorporating flame-resistant materials and design elements to minimize fire spread risk throughout your projects when serving customers in fire zones.

No other decking material offers the combination of beauty and performance found in TimberTech Advanced PVC while providing the critical fire safety specifications homes in fire zones need: Ignition-resistant designation, Class A Flame Spread Rating, and/or WUI Compliance for builds in high-risk areas.

Real Wood Beauty that's Better for Fire Zones

Provide your customers with the bold, character-rich texture of popular hardwoods like white oak and walnut without the ongoing maintenance requirements. TimberTech’s capped polymer decking features proprietary materials technology that delivers sophisticated, real wood aesthetics, allowing customers to enhance projects with premium finishes while eliminating future sanding, staining, or sealing concerns.

While the initial cost to build with TimberTech boards is typically more expensive than wood, there’s no resurfacing or staining, and an Advanced PVC or Composite deck will last for decades to come, which means long-term savings for homeowners that will continue to add up.

TimberTech’s Fire-resistant Decking is in a Class of its Own

TimberTech's Vintage and Landmark Collections have an Ignition Resistant designation and a best-in-class flame spread rating – Class A – which means they burn at a slower rate and are unlikely to contribute to aggressive flame spread. That’s a key differentiation and selling point that traditional wood and composite decking alternatives can’t claim.
