Wood's physical and chemical properties change during thermal modification. When it's heated, the wood releases moisture and its chemical composition is transformed.

Thermo Ash Decking Processing
The thermal modification gives Thermo Ash a beautiful golden-brown tone. In addition to being durable, our thermally modified Thermo Ash is environmentally friendly, as the thermal modification process is chemical-free and no harmful waste is generated. Thanks to the heat treatment, they improve ash's properties, and, thanks to that, it has a longer service life, acoustic properties and greater dimensional stability. It is lighter and therefore prevents possible problems. Thermo wood supplied by us is produced by the WTT method, which uses heat treatment of wood at 180° C.
