Thermowood tongue-and-groove façade profiles offer a durable and high-quality solution for modern wooden façades as well as interior cladding. They are made from natural wood treated with the original Finnish Thermowood process, 212 °C Thermowood D which significantly enhances dimensional stability, resistance to moisture, decay, and wood-destroying organisms — all without the use of chemical treatments. The tongue-and-groove system ensures precise alignment, easy installation, and a clean, uniform surface. These profiles are ideal for ventilated façades, wall cladding, soffits, and other architectural elements in both exterior and interior applications. Thermowood retains the natural wood grain, feels pleasant to the touch, and perfectly complements contemporary architecture with a focus on aesthetics, long-lasting performance, and sustainability.
