Aurora sits in one of Colorado’s most fire-prone corridors. Dry summers, seasonal wind patterns, and proximity to open land mean that what your deck is made of matters more here than it would in most other places.
O’Keefe Built installs fire-resistant decking in Aurora using Trex composite boards, which undergo third-party fire-rating testing and perform significantly better than wood in wildfire exposure scenarios. It also happens to look great and hold up well under Colorado’s climate, which is a conversation worth having before you commit to a material.
Why Composite Decking Is the Safest Decking Material for Wildfire Zones
Standard pressure-treated lumber ignites readily from direct flame and airborne embers, which are the two most common causes of deck ignition during wildfire events. Once a wood deck catches fire, it can travel into the substructure and into the home itself.
Trex composite decking addresses this at the material level. Boards are composed of 95% recycled wood fiber and plastic film encased in a protective polymer shell. That shell limits how easily the organic core is exposed to heat and flame, and it produces a board that does not splinter, rot, or need annual sealing.
Trex boards carry Class A, B, or C fire ratings under ASTM E108 testing, depending on the product line and substructure. Class A is the highest classification available and covers:
- Flame spread across the board surface under sustained ignition
- Burning brand resistance, simulating airborne embers landing on the deck
- Intermittent flame testing to see if the material sustains combustion after the ignition source is removed
For Aurora homeowners near open land, the burning brand test is the most relevant. It replicates exactly what happens when embers travel during a nearby fire. Trex boards in the Class A category resist it. Standard lumber does not.
Trex Product Options for Fire-Resistant Decking
Trex Transcend
O’Keefe Built’s go-to recommendation for fire-sensitive builds. Transcend achieves a Class A fire rating over a noncombustible substructure and features fully capped composite construction, with a polymer shell that protects the entire board. Available in over 20 colors, including lighter tones that run cooler in Colorado sun.
Trex Enhance and Trex Select
Trex’s mid-tier and entry-level lines each carry a Class B fire rating under standard installation. Still significantly more fire-resistant than wood decking, and a solid option when Class A is not required by code.
Note: The fire rating depends on both the board and the substructure. A Trex Transcend board over wood framing achieves a lower classification than the same board over steel or concrete. O’Keefe Built confirms the right configuration at the start of every project.
Fire-Resistant Decking and WUI Compliance in Aurora
If your property falls within a designated Wildland Urban Interface zone, your deck may be subject to material and framing requirements under Colorado’s adopted WUI codes. O’Keefe Built verifies ignition zone status for every Aurora project address before the design phase begins and handles permit documentation where WUI requirements apply.

Aurora Fire-Resistant Decking FAQs
Is Trex actually fire-resistant, or is that just a marketing claim?
It is third-party certified. Trex boards are tested in accordance with ASTM E108, the same standard used for roofing materials. The rating covers flame spread, smoke development, and ember resistance. The specific classification depends on the product and installation configuration.
Does my Aurora property fall under WUI code requirements?
It depends on your address. O’Keefe Built checks ignition zone status before any design work begins. For a full breakdown, visit our wildfire mitigation and WUI compliance page.
Do I need steel framing to get the Class A fire rating?
For Trex Transcend to achieve Class A, the substructure must be noncombustible, typically steel or concrete. Installed over pressure-treated wood framing, the same board achieves a lower classification. If Class A is the goal, substructure planning is part of the conversation from the start.
Does fire-resistant composite decking look different from regular composite?
No. Trex Transcend is available in the same colors and finishes as the rest of the Trex lineup. The fire rating comes from the material composition and substructure configuration, not from any visible coating or treatment. You get the same wood-grain texture and color range, with built-in fire performance.
How does Trex composite hold up in Colorado’s climate?
Well. The capped construction resists moisture absorption, UV degradation, and the freeze-thaw cycling that cracks and cups pressure-treated lumber over time. No staining, sealing, or sanding required.
