Thermory USA offers four species of thermally modified wood decking: Benchmark Ash, Benchmark Oak, Benchmark Pine, and Kodiak Spruce. All four are WUI-certified, giving projects in wildfire-prone areas more options without limiting the design possibilities.
When choosing decking, you’re balancing more than appearance. Climate, durability, maintenance, budget, board width, texture, and even wildfire considerations can all influence the right material for the job.
So, which one is right for your deck?
Benchmark Ash: Refined and versatile
Thermory Benchmark Ash brings the clean, sophisticated look of thermally modified hardwood to outdoor spaces.
Its distinctive grain and refined appearance make it a natural fit for modern residential decks, pools, outdoor living spaces, and high-end commercial projects. Ash also offers excellent hardness and durability, making it a strong choice for areas that see plenty of foot traffic.
As it weathers, untreated ash develops a natural silver-gray patina while maintaining the performance benefits of thermal modification.
Choose Benchmark Ash when: You want a refined hardwood aesthetic with a strong combination of beauty, durability, and versatility. Explore the collection.
Fire-Safety: WUI-Certified | Available with SaferWood™ Fire Retardent Protection (Class A)
Benchmark Pine: Warm, natural, and approachable
Thermory Benchmark Pine brings the familiar warmth and character of knotty Scots Pine to the outdoors.
Natural knots and variation give it a relaxed, organic appearance that works especially well for residential decks, cabins, lake houses, and projects designed to feel connected to the surrounding landscape.
Benchmark Pine also offers an accessible way to bring the benefits of thermally modified wood to a project without moving immediately into premium hardwoods.
Choose Benchmark Pine when: you want warm, natural character and the benefits of thermal modification at a more approachable price point. Explore the collection.

Kodiak Spruce: Wider by design, rustic, bold
Available in 8-inch-wide boards, Kodiak by Thermory creates a bold look with fewer seams across the deck. Its brushed surface highlights the natural texture of the wood and gives the decking a distinctive, tactile appearance.
The combination of wide boards, visible grain, and thermal modification makes Kodiak particularly well suited to contemporary architecture and expansive outdoor spaces.
Choose Kodiak when: you want wider boards, a more textured appearance, and a distinctive rugged look. Explore the collection.
Fire-Safety: WUI-Certified
Benchmark Oak: Classic hardwood character
Benchmark Oak offers a more traditional hardwood look, with pronounced grain and the substantial character Red Oak is known for.
Thermal modification enhances Oak’s dimensional stability and durability, making it suitable for demanding exterior applications while maintaining the natural qualities that make hardwood so appealing.
It’s a particularly good fit when the decking is intended to feel like an architectural feature rather than simply a functional surface.
Choose Oak when: you want the richness, grain, and character of classic hardwood with enhanced outdoor performance. Explore the collection.
Fire-Safety: WUI-Certified
Four species. One thermally modified advantage.
While each species has its own character, they all share the same fundamental advantage: Our proprietary thermal modification process.
Using only heat and steam, we permanently alter the wood’s properties—reducing its tendency to absorb moisture by 40–50% and helping minimize the swelling and shrinking associated with changes in humidity.
The result is 100% real wood engineered for demanding exterior applications, with no plastic and no chemical wood preservatives added during the thermal modification process.
And with all four Thermory decking species WUI-certified, you don’t have to sacrifice design flexibility to meet fire-safety requirements. You can choose the species, look, texture, and character that best fit your project—and still get the performance you expect from Thermory.
