Thermo-treatment of wood has an effect on wood’s chemical composition is mainly caused by thermo degrading of hemicelluloses and through that on the physical properties of wood. In addition to better durability the advantages of thermotreated wood are reduced hygroscopicity and improved dimensional stability. The listed below properties of thermo-treated wood may slightly vary due to the natural difference between lumber species and treatment temperature.
Intense-treated wood results in outstanding dimensional stability and durability, extending the lifetime of the wood considerably. Therefore the Intense-treated wood is suitable for both in- and outdoor usage. It is most widely used as decking, cladding and flooring. Due to the high stability it can also be used in wet rooms and on heated floors. Depending on the species the colour of the Intense-treated wood varies from medium to luxurious dark brown.
Thermo-treated wood has a very long lifetime, higher dimensional stability and lower equilibrium moisture content compared to untreated wood. All the advantages of thermo-treated wood make it an environmentally friendly alternative to tropical hardwoods, gaining popularity all over the world.
