Heat treated wood

Wood that is allowed to dry at high temperatures becomes resistant without chemicals. An eco-friendly option for special hardwoods.

Heat extends durability

Spruce and pine from Swedish forests can gain greater resistance through heat treatment. The nutrients in the wood disappear during treatment, which means that mould and rot have difficulty taking hold. Such wood is classified under EN 350-2 as resistant, with the same resistance to wood-destroying fungi as Western Red Cedar. However, heat-treated wood should not be used in direct contact with the ground.

A warp-resistant alternative

Heat-treated wood contains very little moisture and maintains its shape even under shifting moisture conditions. Cracking is prevented by conditioning the wood after drying. The result is a material whose colour and characteristics are reminiscent of exotic types of wood.

Beautiful shades all the way through

When wood is heat treated, it takes on a warm shade of brown. The exact shade depends on the type of wood, the temperature and for how long the wood is treated. Because the entire material is treated, it’s possible to sand the surface without changing the shade. However, the sun’s UV rays also affect heat-treated wood, and turn it grey over time. This can be avoided by treating the material with pigmented oil.

A sustainable lifecycle

Because no chemicals are used in its production, heat-treated wood is an eco-friendly choice. Waste wood and end-of-life materials are sorted as wood and can be burned to generate new energy.
