Thermally Modified Hardwoods & Softwoods

Your U.S. Source for
Thermally Modified Wood

As a U.S. producer of thermally modified hardwoods and softwoods, we’re uniquely positioned to support manufacturers, builders, architects, and craftsmen with a wide variety of thermally modified lumber and finished products.

​

We don’t believe in limiting what we can create—because the possibilities for thermally modified wood continue to grow as the technology evolves. Each species responds differently to modification, making some ideal for certain applications while others may not be. We’re always experimenting and pushing boundaries—if we haven’t tested a species yet, we’re ready to.

Let's Explore What's Possible
Curious how thermally modified wood could enhance your next project or product line? It all starts with a conversation. Give us a call, and let’s explore the possibilities together.

The
Why & How

ThermaPro wood is beautiful, rot-resistant, extremely durable, completely sustainable, chemical-free 

natural wood. 

Thermally Modified Wood is a game-changing building material now available in the United States. Not only is it chemical-free, eco-friendly, and longer-lasting than common wood building materials, it’s also sustainable and helps preserve precious rainforests.

 

How, you ask?

Through a process called thermal modification. It’s an all natural process that changes the physical properties of wood, removing the organic compounds and making it hydrophobic, i.e. it doesn’t hold water.

No water = no rotting, cupping, or warping. 

​

Thermally modified wood is the most sustainable, durable, eco-friendly and natural facade and outdoor building material available today. Find out more about the features and benefits of ThermaPro Wood.

What is Thermal Modification?

The simple explanation:
Kiln-dried wood undergoes a special process in a vacuum kiln, utilizing heat and pressure. Basically, this cooking zaps out all the organic stuff trapped within the wood cells. With the organic bits out of the picture, the wood cells become water-repellent champs - no expanding, contracting, or serving as snacks for bugs or fungi.

 

The result? A wood that's naturally tough against water, decay, and creepy crawlies. Plus, by ditching the water and other organic stuff, the wood gets denser, tougher, and more steady, so it stays put after you've installed it. And let's not forget, the cooking also gives the wood a sleek, dark brown hue, so it's a win-win for looks too.

So, what's it good for? 

Because thermally modified wood is weather resistant and doesn’t react to changes in humidity, it's perfect for stuff like cladding, fencing, decking -all those outdoor jobs where wood faces the elements, plus humidity-rich environments like saunas and wine cellars. Don't forget, it also rocks as an interior accent thanks to its gorgeous color, lack of chemicals, and durability.

The Modification Process

Phase 1

Kiln dried wood is placed in a special oxygen-deprivation kiln where the temperature is gradually raised. In the first heat cycle, the moisture content of the wood is reduced to nearly zero, expelling the pitch and sap.
