Thermally modified wood, also known as thermo wood, is a type of wood that has been treated with heat to improve its properties. During the treatment, the wood is heated to temperatures between 160°C and 220°C in a special oven or kiln, in the presence of steam or nitrogen gas.
The heat treatment process has several benefits for the wood. It increases its resistance to decay, fungi, and insects, making it more durable and long-lasting. It also reduces the wood's ability to absorb moisture, which helps to prevent warping, cracking, and splitting. Additionally, the heat treatment can improve the wood's dimensional stability and color, giving it a more uniform appearance.
Thermally modified wood is used in a variety of applications, including decking, siding, cladding, and furniture. It is also a sustainable and eco-friendly alternative to chemically treated wood, as the process does not involve the use of any harmful chemicals.
