Thermowood is a controlled treatment process where the wood is exposed to a temperature of 212 °C for 48 hours and throughout the time is monitored by dozens of sensors that monitor the correct temperature and humidity. Wood treated in this way acquires new properties and the THERMO D qualification and the wood is intended for outdoor use.

The advantages are: dimensional and shape stability, better insulating properties, longer durability and resistance to all wood pests. In addition, thanks to this process, the wood is freed from all harmful substances.Thermowood does not require any maintenance. The standart color of THERMOWOOD is honey which changes to gray over time (3-6 months). Alternatively, it is possible to paint THERMOWOOD with a color of your choice.
