We also manufacture treated thermos wood. For production, only the Northern European pines of the best quality are used. The pine is light with regular texture, appreciated for its pleasant smell. Thermo-treated wood is produced at high temperature and steam. As a result of the thermos treatment process, dimensional stability, biological durability and privacy properties are improved. For ceilings we use the Icopal Bituminous Tiles of Finland, which have 10 years of warranty.
