Thermowood is a transformative material in the construction and design industries, crafted through a heat treatment process that enhances its durability, stability, and decay resistance without chemical additives. By heating softwood between 180°C and 220°C and using steam to prevent drying and cracking, the wood is not only strengthened but also enriched with a deep, aesthetically pleasing color.

The heat treatment alters the wood's cellular structure, significantly increasing its resistance to moisture, decay, and fungal growth, making it ideal for demanding outdoor applications like facades and decking. Unlike untreated wood, Thermowood remains dimensionally stable, resisting warping, swelling, or shrinking under changing humidity, which is crucial for precise applications such as flooring and joinery.

Thermowood contributes to environmental sustainability with its chemical-free process and use of wood from sustainably managed forests, enhancing insulation properties and supporting energy-efficient building practices.
