What is Thermal Modification

Thermal modification is a natural, eco-sustainable process carried out at high temperatures in a controlled atmosphere. It enhances wood durability, dimensional stability and biological resistance, without the use of chemical additives.
The result is hardwood and softwood species transformed into high-value, low-maintenance materials for demanding outdoor and architectural applications.

Applications

Thermally modified wood is widely used in: Building & construction

  • Outdoor: decking, façades, siding and cladding, exterior paneling.
