A Milestone for American Innovation in Thermally Modified Wood

Arbor Wood Co. is proud to announce that we are now the first (and only) U.S.-based member of the International ThermoWood® Association (ITWA)—a major milestone that reflects not just our growth as a company, but our ongoing commitment to excellence, sustainability, and performance in the thermally modified wood industry.

Why This Matters

The ITWA, headquartered in Finland, sets the global standards for thermally modified wood products. Its members represent a select group of manufacturers around the world who adhere to strict technical and quality guidelines—ensuring consistency, stability, and durability in every board.

Becoming a member of this prestigious organization signals to our partners, customers, and the wider industry that Arbor Wood Co. meets and exceeds these international standards. We’re not just making thermally modified wood—we’re crafting a product that holds its own on the world stage.

A Commitment to Quality and Craftsmanship

From the very beginning, Arbor Wood Co. has been focused on delivering wood products that architects, designers, builders, and homeowners can trust. Our thermally modified wood is sourced from responsibly managed U.S. forests and refined through a high-heat and steam process—resulting in material that is naturally durable, dimensionally stable, and chemical-free.

Joining ITWA validates the care and precision that go into every product we make, and it provides our clients with even more assurance that Arbor Wood products perform to the highest standards—whether they’re installed on a lakeside home in Minnesota or a coastal project in California.

What This Means for Our Future

This is more than just an international badge of honor. As a member of the ITWA, Arbor Wood Co. now has access to:

A global network of thermally modified wood leaders
Ongoing research and innovation in thermal modification
Performance benchmarking and technical collaboration
New opportunities for product development and international growth

As interest in sustainable building materials continues to rise, Arbor Wood Co. is uniquely positioned to lead the way in the North American market with products that align with both domestic values and global expectations.

What It Means for You

Whether you’re specifying materials for a high-performance project or looking for reliable products to offer your customers, Arbor Wood Co.’s ITWA membership is another reason to choose our thermally modified wood.

For architects: you can specify Arbor Wood with even more confidence
For builders: you’ll work with a material proven to last in real-world conditions
For homeowners: you’ll enjoy natural beauty and durability without compromise

Looking Ahead

We believe great materials build great places—and with the support and recognition of the International ThermoWood® Association, Arbor Wood Co. is ready to continue setting the standard for American-made thermally modified wood.

Thank you to our partners, customers, and supporters who have helped us reach this moment. We look forward to what comes next.
