Thermally Modified Wood

Lifetime Performance with Sustainable Harvesting Practices

Architects and builders seeking a long-lasting, eco-conscious alternative to traditional timber are turning to thermally modified wood. Through a high-heat, chemical-free process, this advanced material is engineered for exceptional durability, dimensional stability, and decades of reliable performance. Sourced from responsibly managed forests and transformed without harmful chemicals, thermally modified wood delivers natural beauty, reduced maintenance, and a lower environmental footprint.

With Fisher’s premium thermally modified wood product lines Abodo® and Imbue™, you can specify a cladding or soffit solution designed to stand the test of time—sustainably.

Benefits of Thermally Modified Wood

1. Exceptional Durability & Rot Resistance

Thermal modification removes sugars and extractives, rendering the wood biologically inert. The result is a highly durable material with a service life exceeding 30 years in above-ground cladding applications.

2. Superior Dimensional Stability

Thermally modified wood experiences up to 90% less swelling and shrinkage, reducing the risk of warping, cupping, and movement in variable climates—ideal for façades that need to stay straight and true.

3. Naturally Rich Aesthetic

The process creates a consistent, warm brown tone throughout each board, which can be preserved with a UV-stable finish or left to gracefully weather into a silvery-grey patina—both options offering timeless visual appeal.

4. Low-Maintenance Performance

Thanks to its reduced moisture content and inherent resistance to decay, thermally modified wood requires minimal upkeep. Many projects retain their integrity and beauty for years with only occasional touch-ups.

5. Non-Toxic & Environmentally Responsible

Free from chemical preservatives or fungicides, thermally modified wood is safe, fully recyclable, and typically sourced from responsibly managed forests. Many products carry certifications such as FSC® and Declare Red List Free, aligning with today’s sustainable building standards.
