Why Choose Thermally Modified Wood Decking?
Our thermally modified wood decking is designed for superior durability, stability, and natural resistance to moisture, insects, and decay. Through an innovative heat and steam treatment process, the wood undergoes a complete molecular transformation, making it hydrophobic and highly resistant to warping, swelling, and rotting. This ensures long-lasting performance, even in high-humidity environments.
The Science Behind Thermally Modified Wood
Originally developed for softwood lumber, the thermally modified wood process has been adapted to enhance hardwood species like maple, ash, birch, and oak. To achieve this, ThermalWood Canada developed over 200 unique treatment recipes, ensuring optimal performance for each type of wood. The lumber is carefully stacked with two-inch gaps to allow heat and steam to circulate evenly inside our propane-heated kiln. The temperature and duration are precisely controlled for each species, transforming the wood into a more stable, weather-resistant material.
This process alters the wood’s sugars, making them indigestible to insects and mold while also preventing moisture absorption. As a result, thermally modified wood decking maintains its structure and resists environmental damage without the need for harsh chemical treatments. Additionally, the heat treatment gives the wood a rich, deep color that can be preserved with a UV finish or left untreated to develop a beautiful gray patina over time.
Why Choose Thermally Modified Wood Decking?
Our thermally modified wood decking is the perfect solution for any outdoor space, offering:
- Exceptional Durability – Naturally resistant to rot, insects, and decay without chemical treatments.
- Enhanced Stability – Reduced swelling, shrinking, and warping, even in extreme weather conditions.
- Sustainable & Chemical-Free – Heated and steamed for modification, making it safe for homes, businesses, and the environment.
- Versatile Applications – Ideal for decks, patios, boardwalks, poolside areas, and waterfront properties.
With its impressive strength and weather resistance, thermally modified wood decking is particularly well-suited for marine environments and humid climates. It has been tested and proven in various regions, from the harsh winters of Canada to the tropical conditions of the Caribbean. In fact, when architects in Barbados placed a piece of our wood inside a termite mound for six months, the termites completely ignored it—demonstrating its superior resistance to pests.

Cutek
Cutek Extreme is a wood protection oil that keeps your thermally modified wood decking looking great for many years to come.
Many wood coatings allow moisture to seep into the wood, which can cause warping and splitting. Cutek oils penetrate the wood, creating protection from within. No peeling or flaking. This makes it an excellent choice for preserving the beauty and durability of thermally modified wood decking.

Cutek Colour tone
We offer 18 different options of Cutek Colourtone to ensure that you get the perfect colour for your thermally modified wood decking or siding.
our clip system
ThermalWood Canada has the sole rights to manufacture state-of-the-art GRAD clips (outside of France) to create an easy, DIY installation of your thermally modified wood decking and cladding. The clips are made of POM (polyoxymethylene), which is one of the highest performing plastic on the market, the same to manufacture soles of ski boots.
