Is Your Deck Fire-Safe? Why TimberTech PVC is a Smart, Safe Choice for Fire Resistance

As wildfire risks and dry conditions continue to increase in many parts of the country — especially in high-elevation and dry-climate areas like Utah — homeowners are starting to ask a critical question: Is my deck safe from fire?

While traditional wood decks can catch fire easily and contribute to flame spread, modern materials like TimberTech Advanced PVC decking offer a safer alternative. At Wasatch Deck and Rail Supply, we strongly recommend TimberTech PVC for homeowners concerned about fire safety — and here’s why.

Here is map showing the most at risk areas for homeowners of wild fire:

The Fire Risk of Traditional Decking Materials

Wood decks are beautiful, but they’re also highly flammable. Dry weather, wind, and nearby vegetation can quickly turn a small flame into a dangerous fire. Not only do wood decks ignite easily, but they can also accelerate fire spread to the rest of the home.

Even many composite decks — while more resistant than wood — don’t always meet high fire safety standards.

What’s at stake:

• Embers from grills, fire pits, or wildfires

• Flame spread to siding and roof

• Costly repairs, safety hazards, and insurance issues

Fire Test Across Different Composite Decking

TimberTech PVC Decking: A Fire-Resistant Leader

TimberTech’s Advanced PVC decking line is one of the few products on the market with a Class A Flame Spread Rating, the highest rating in the industry for deck materials. This means TimberTech PVC resists ignition and slows fire spread significantly better than wood or lower-grade composites.

What makes it different?

• Made without wood fillers, which lowers flammability

• Engineered polymers resist ignition

• Meets WUI (Wildland Urban Interface) standards in fire-prone zones

• Holds a Class A Flame Spread Rating (ASTM E84 test)

🛠️ Pro Tip: If you’re in a wildfire-prone area or just want peace of mind around grills or fire features, TimberTech PVC is your safest choice.

Ideal for Utah Homeowners

Utah’s dry, desert climate — especially along the Wasatch Front and in high-elevation communities — makes fire safety a serious consideration for any exterior upgrade. Homeowners in areas like Park City, Draper, Herriman, St. George, and Heber are increasingly choosing non-combustible decking materials that perform under pressure.

TimberTech PVC decking isn’t just beautiful — it’s a smart investment in long-term safety and home protection.

The Bonus: Low Maintenance + Long-Term Durability

Beyond fire safety, TimberTech Advanced PVC offers:

• Incredible durability

• Moisture and mold resistance

• Fade-proof, stain-resistant finishes

• Realistic wood textures in a wide range of colors

It’s the ideal solution for homeowners who want a high-end look without the risk or upkeep of traditional wood.
