An innovative process that gives wood high performance properties.
Thermally modified wood is a sustainable, economical and environmentally-friendly solution for exterior wood, due to the elimination of all chemical and biological products in its treatment. The treatment is carried out by putting the material in a chamber with an oxygen-free atmosphere at high temperatures for several hours. This process will vary depending on the species of wood, the required properties and the dimensions of the pieces.
A SUSTAINABLE MATERIAL
Consuming wood products contributes positively to the maintenance and growth of forests. Each m3 of wood used as a substitute for another material can reduce CO2 emissions into the atmosphere by 2 tons. It is also our responsibility to guarantee development based on renewal of resources and protection of the environment. That is why we actively promote the use of wood from PEFC forests, which is a certification that guarantees sustainable forest management.
These certifications serve as a guarantee for consumers so they know that they are buying wood products from sustainably managed forests. By choosing PEFC products, buyers can help combat illegal logging and promote sustainability.
USING A BALANCED COMBINATION OF HIGH TEMPERATURE AND STEAM, FOR SEVERAL HOURS, TRANSFORMS THE WOOD CHEMICALLY AND STRUCTURALLY
Up to 50% increase in dimensional stability, as it is not affected by humidity changes and internal stresses are reduced.
Up to 25% more thermal insulation, as it benefits from low thermal conductivity.
Greater uniformity of colour, a toasted tone throughout the product, with a very smooth surface finish.
THE HEAT TREATMENT MAKES THE THERMALLY MODIFIED WOOD HIGHLY WEATHER-RESISTANT
It’s only wood, naturally.
We use an entirely natural process with zero chemicals to remove everything that would affect the product’s durability, leaving behind a material that will last longer.
This makes it an ideal treatment for exterior cladding, both for decking and for walls and ceilings.
We use a special kiln that controls the density of water vapour inside, preventing the wood from warping and cracking.
The resin components vaporise at temperatures above 200°C, making the wood more fire-resistant and preventing the presence of fungi from untreated wood.
Not only do we reduce the moisture of the product by up to 50%, but we also protect the wood to make it resistant to water absorption, thus avoiding deformation due to changes in humidity.
Pine trees belong to the conifer group; they are resinous woods, with marked annual rings and a soft and uniform pale colour. Each piece of wood has a distinct and characteristic pattern that enhances its natural beauty. The thermal treatment alters the molecular structure of the wood, which modifies some of its properties:
The wood darkens and the colour becomes more uniform, both in the sapwood and in the heartwood.
The new chemical composition of the wood has lower mechanical properties. This means it is less elastic and it flexes less, which is why we need to place the slats at the recommended distance.
It is lighter due to the change in its composition and the loss of humidity, and the density of the wood is reduced by 5-15%.
Wood tends to become greyish when exposed to the sun, so we recommend applying a suitable protective lacquer.
