Thermowood is a thermal modification process that preserves the wood in its most natural and flawless state for a long-life journey. It involves heating wood to temperatures of up to 212oC and preserving it with steam causing certain chemical changes within the wood. During the process the woods natural colour is altered resulting in the brown colour due to caramelization of glucose inside the wood and more importantly the dimensional stability of the wood is greatly increased. The dimensional stability results in high durability and stability. The process also reduces the water absorption of wood consequently increasing the decay resistance while decreasing swelling and shrinking.


The products treated with the Thermowood method are;

100% natural: The wood is free from resin and chemicals. No chemicals are used during the production process.
