Thermowood is produced by treating timber at high temperatures in special kilns.
Heat treatment alters the cellular structure of the wood. It reduces the equilibrium moisture content by up to 50% and makes the wood less susceptible to reabsorbing moisture from the air.
The process also expels resins and breaks down some of the timbers natural sugars. Heat treatment produces a moer stable and durable timber. It brings hardwood performance to environmentally friendly Scandinavian hardwood.
Thermowood is ideal for external timber claddings, worktops, garden furniture, and decking products.
The Benefits of Thermowood:
- Enhanced Durability
- Finforest category 2 Treated pine achieves natural duability classification grade 2 (durable) – a level that’s equal to Western Red Cedar and Eropean Oak (tests according to Standard EN350-1 Natural Durability). Better still, the enhanced durability applies to both the hearwood and sapwood.
- Environmentally Sound
- All our heat-treated softwood carries PEFC certification. Which guarantees the timber is from well managed forestry.
- Improved stability
- Thermowood is more stable than untreated softwood. The process reduces movement through shrinkage, swelling and distortion by up to 50%.
- Richer Colour
- Heat treatment darkens the colour of timber all the way through to the core, so even when cut the colour and protection remain constant. The higher the temperature, the darker the colour.
- Easier Maintenance
- The improved stability of Thermowood and the lack of resins increases the life expectancy of surface coatings.
