Frequently asked questions

ThermoWood is wood that has been thermally modified through a controlled process involving high temperatures and steam, altering its chemical and physical properties to enhance durability, stability, and resistance to decay without using any chemicals.

ThermoWood is produced by heating wood to temperatures between 160°C and 230°C in a low-oxygen environment, often using steam to prevent burning. This process changes the wood’s cell structure, reducing its moisture content and making it more resistant to biological decay.

Common species used for ThermoWood include pine, spruce, ash, and beech. These types of wood respond well to thermal modification, enhancing their natural properties and making them suitable for a wide range of applications.

ThermoWood offers several benefits, including improved durability, enhanced resistance to decay, reduced moisture absorption, dimensional stability, and a lower tendency to warp or crack. It also has a beautiful, rich color and does not require chemical treatments.

Yes, ThermoWood is environmentally friendly. The production process does not involve any harmful chemicals, and the increased durability extends the wood’s life, reducing the need for replacement and minimizing environmental impact.

ThermoWood is suitable for various applications, including cladding, decking, interior and exterior furniture, sauna interiors, and decorative elements. Its enhanced properties make it ideal for use in environments with high humidity or exposure to the elements.

Compared to untreated wood, ThermoWood has superior durability, resistance to decay, and dimensional stability. It also absorbs less moisture, reducing the risk of warping and cracking. The thermal modification process also gives ThermoWood a darker, richer color.

Yes, the thermal modification process makes ThermoWood more resistant to insects and fungi. The high temperatures alter the sugars and other compounds in the wood that typically attract pests, making it less appealing to insects and less prone to fungal decay.

ThermoWood requires less maintenance than untreated wood due to its increased resistance to decay and moisture. However, like all wood products, it may require occasional cleaning and, if exposed to direct sunlight, may benefit from surface treatments to maintain its color.

Yes, ThermoWood can be painted or stained. Its reduced moisture content allows for better absorption of paints and stains, resulting in a longer-lasting finish. However, its natural appearance is often appreciated, and many choose to leave it untreated.

Yes, ThermoWood is highly suitable for outdoor use. Its enhanced resistance to moisture and decay makes it an excellent choice for applications such as decking, cladding, and outdoor furniture, where exposure to the elements is a concern.

ThermoWood performs well in both hot and cold temperatures. Its low moisture content and increased stability help it withstand temperature fluctuations, reducing the likelihood of warping, cracking, or shrinking.

Yes, ThermoWood is considered a sustainable building material. It is made from renewable wood sources, and the thermal modification process is chemical-free. Additionally, its durability and long lifespan contribute to sustainability by reducing the need for frequent replacements.

ThermoWood has a lower equilibrium moisture content than untreated wood, making it less likely to absorb water. This property helps prevent swelling, shrinking, and warping, even in humid conditions or when exposed to water.

ThermoWood naturally changes color over time, especially when exposed to UV light. It may develop a silver-gray patina if left untreated outdoors. This aging process does not affect the wood’s structural integrity or performance.

ThermoWood is generally not recommended for load-bearing structural applications because the thermal modification process can reduce the wood’s mechanical strength. It is best used for non-structural purposes such as cladding, decking, and interior applications.

ThermoWood has a significantly longer lifespan than untreated wood, especially in outdoor applications. With proper maintenance, it can last 20-30 years or more, depending on the environment and exposure conditions.

Yes, ThermoWood is safe for indoor use. The thermal modification process does not use any harmful chemicals, making it a healthy choice for indoor environments. It is often used for interior paneling, flooring, and sauna construction.

ThermoWood has a distinctive appearance with a rich, dark color that resembles tropical hardwoods. The thermal modification process also enhances the natural grain and texture of the wood, providing a unique and attractive look.

ThermoWood’s dimensional stability and low moisture content help improve the energy efficiency of buildings. When used in cladding and insulation applications, it can reduce thermal bridging and improve the building envelope’s overall performance, leading to better insulation and energy savings.
