When it comes to choosing the best siding for your home, thermally modified wood siding stands out for its durability, beauty, and environmental sustainability. Thermally modified wood in Canada has set a new standard in cladding materials!
What Is Thermally Modified Wood Siding?
Thermally Modified Wood (TMW) is a type of wood treated in an oxygen-free condition through a controlled heating process. This process is known as thermal modification. It alters the cellular structure of the wood and enhances its durability and stability for outdoor use.
Thermally modified wood siding is more durable against warping or twisting. As a result, by choosing TMW siding, you enjoy a long-lasting and beautiful exterior that requires minimal maintenance.

Thermally Modified Wood Siding Benefits
It has several advantages over traditional materials:
- Increased Durability: The thermal modification process removes nutrients that would otherwise attract fungi and insects. This process makes the wood more resistant to rot and decay and it perform like wood polymer composite.
- Stability: Thermally modified wood siding is less prone to warping and shrinking and like aluminum siding, maintains its shape better than untreated wood.
- Sustainability: The process extends the life of the wood and reduces the need for frequent replacements.
- Aesthetic Appeal: With its rich, refined look, thermally modified wood adds a touch of elegance to any architectural design.
TMW Siding Problems
While TMW siding has many benefits, there are some considerations:
- Cost: The thermally modified wood siding price can be more expensive than traditional wood siding due to the additional processing required.
- Brittleness: The wood may become more brittle, which can lead to issues with handling and installation.

Types of TMW Siding
Thermally modified wood siding is available in a variety of species, each offering unique benefits for different applications.
Some common types are:
Ash
It is a popular choice for wood decking due to its excellent dimensional stability and attractive grain pattern. It’s often used for ability to withstand the elements and maintain its appearance over time.
Pine
It is another common species used for thermally modified wood siding in Canada.
Pine is among the most common trees in Canada. It’s known for its affordability and availability.
Pine provides a classic look while offering improved resistance to decay.
Spruce
Spruce TMW siding is favored for its light weight and ease of installation.
It also has a fine, uniform texture that appeals to those seeking a subtle and clean aesthetic.
Hemlock
This wood is chosen for siding due to its natural beauty and resistance to staining.
It has a uniform appearance and is less prone to splintering. Therefore, it is a safe choice for your homes.
Larch
Larch thermally modified wood is valued for its durability and resistance to rot. It has a bold grain pattern that can add character to any building’s exterior.

What Is the Best Thermally Modified Wood?
Every wood species undergoing the thermal modification process is suitable for various architectural styles and climates.
Choosing the right type of thermally modified wood decking depends on many factors. These factors are the specific needs of your project, including aesthetic preferences, climate considerations, and budget.
For instance, European and North American White Ash are praised for their high quality. This results in a rich brown tone and exceptional rot resistance after intense thermal modification. They are suitable for exterior and interior applications and offer a classic appearance and longevity.
Is Thermally Modified Wood Siding Sustainable?
Yes, this wood siding is considered sustainable for several reasons:
- Eco-Friendly Process: The thermal modification process uses heat and steam to enhance the wood’s properties. This eliminates the need for chemical preservatives.
- Increased Durability: TMW has a longer lifespan compared to untreated wood, which reduces the frequency of replacement and the demand for raw materials.
- Sourced from Sustainable Forests: Many TMW products are sourced from sustainably managed forests.
Overall, this wood cladding material aligns with sustainable building practices by offering a durable, chemical-free, and long-lasting material option.
