ThermoWood® Ash is a thermally modified hardwood renowned for its durability, stability, and rich colouring. Sourced exclusively from International ThermoWood® Association members, it is particularly well suited to applications where adverse weather conditions are a consideration.
Exceptional durability – ThermoWood® Ash achieves a high durability classification after thermal treatment offering a long service life.

Certified quality – Sourced exclusively from International ThermoWood® Association members, ensuring compliance with the patented ThermoWood® Thermo-D treatment classification.
Premium appearance – ThermoWood® Ash is a top-grade timber featuring minimal knots and imperfections. After treatment, the wood takes on a consistent rich brown colour with interesting grain patterns, offering a premium finish.
Environmentally friendly – The modification process is chemical free, using only heat, steam and water.
