Thermowood is a type of timber that undergoes a specialized heat treatment process to enhance its performance and durability. Softwoods, like pine or spruce, are heated to high temperatures (usually between 180°C to 260°C) in a controlled environment without oxygen. This thermal modification alters the wood's cellular structure, reducing moisture content and increasing dimensional stability. As a result, thermowood exhibits improved resistance to decay, insects, and weathering, making it well-suited for outdoor applications such as decking, cladding, and siding. Additionally, the process often gives thermowood a darker, richer color and a more attractive appearance compared to untreated wood. This eco-friendly treatment method, devoid of chemical additives, aligns with sustainable forestry practices and promotes the use of a durable, environmentally conscious building material.
