Built for Performance, Naturally

Thermally modified wood decking delivers exceptional durability—resisting rot, insects, and decay without the use of chemicals. Through our process of heat and steam, the wood becomes dimensionally stable, reducing shrinking, swelling, and warping even in the most extreme weather conditions. The result is a decking material that’s sustainable, chemical-free, and safe for homes, businesses, and the environment.

Proven in Every Climate

From Canada’s harsh winters to the Caribbean’s tropical heat, our decking has proven its performance around the world. In one remarkable test, architects in Barbados placed a piece of our wood inside a termite mound for six months—and the termites ignored it completely. That’s the kind of natural resistance and reliability you can count on from ThermalWood Canada products.

A Global Standard in Wood Innovation

We combine craftsmanship, technology, and sustainability to deliver decking that performs beautifully for decades. Our thermally modified ash offers rich color, long-term stability, and eco-friendly construction. Distributed across Canada—from Alberta to British Columbia—and internationally throughout the U.S., Europe, and the Caribbean, our decking is built to exceed expectations.

Cooking for Performance

Our decking is thermally modified at a precise Thermo-D level — the ideal standard for exterior applications. This process enhances the wood’s stability, durability, and resistance to decay, making it perfectly suited for harsh outdoor environments.

At ThermalWood Canada, we use an open system for thermal modification, allowing us to carefully monitor and control every stage of the process. This approach also ensures that we meet the strict quality guidelines set by the International ThermoWood Association (ITWA) — the world’s only governing body dedicated to maintaining standards and quality assurance in thermally modified wood.
