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.
