Premium Thermowood®
Thermo treated wood is a versatile material for exterior and interior applications in all climates. We select the best Nørdic Pine and Nørdic Ash from well managed forests within a 150km radius of the mills. The thermal modification process uses only heat and steam to change each plank fibre all the way to the wood core.
Our wood is heated to 150°C for 20 hours so that the natural sugars/nutrients are broken down, and the woods moisture content is reduced to 0%. The heat is then r aised to 215°C and held for 4 hours. This is where the cellular structure is altered and the colour process takes place. It darkens and toughens the wood, achieving a low moisture content and dimensional stability.
During the cool down process the temperature is reduced over 24 hours and moisture is reintroduced for end use. The entire 48 hour process is carefully monitored digitally to ensure quality. After the plank is profiled, it goes through a specialised quality control unit called an Optimizer, where boards are scanned for grading and defects. Any defects are automatically rejected.
Thermo treated planks are energy efficient, durable, low maintenance, and decay resistant. This offers more opportunities for architects and designers to use wood in a beautiful and innovative way.
