Thermo-D treatment of every fiber
What is ThermoWood®?
ThermoWood® is a patented brand created by the International ThermoWood® Association. It specifies the natural preservation process to transform wood into a durable product. Through every fiber, the durability class improves from IV or III up to I which implies a lifespan of over 25 years for class I. (EN 350-1)
Consistent quality due to standardized treatment
As a member of the International ThermoWood® Association, our standardized process is identical to the Finnish process, which sets the gold standard of all thermal treatments. Twice a year, we are audited by a Notified Body to maintain a high quality.

ThermoWood® process in 3 phases
Phase 1
Timber dries and moisture content decreases.
- High-temperature drying: 100-212°C
- Moisture level: 20% -> 2%
Phase 2
Kiln is kept at a steady temperature to modify the wood.
- Thermal modification: 212°C
- Moisture level: 2%
Phase 3
Temperature is lowered and the moisture content is increased with steam and water.
- Conditioning/cooling
- Moisture level: 2% -> 4-7%
