🔥 Thermowood Cladding

Thermowood is a thermally modified timber created by heat-treating softwoods like pine or spruce to enhance their durability, stability, and resistance to moisture.

Advantages of Thermowood:

  • Improved Dimensional Stability: Less prone to warping or shrinkage due to the heat modification process.
  • Weather Resistance: Highly resistant to moisture, fungal decay, and insects.
  • Sustainable Choice: Made from renewable softwoods, with no added chemicals.

Ideal for: Modern cladding designs, eco-builds, and weather-exposed structures.
