Thermo Wood

Thermowood is a collective term for thermally modified wood that is becoming increasingly popular in the construction and design world.

Through a specialized treatment process, the wood is heated to high temperatures, resulting in improved properties and enhanced durability. Thermowood offers many advantages over untreated wood, including increased dimensional stability, reduced movement, and improved resistance to moisture, fungi, and insects.

It also retains the natural appearance and color of the wood, making it an attractive choice for façade cladding. Discover the many possibilities of Thermowood at Housewood.com.

Thermally modified wood

Thermally modified wood, also known as thermowood, undergoes a specific process that enhances its properties. During thermal modification, the wood is treated with steam and heat, making it more durable and stable.

In this process, the wood is heated to temperatures between 160°C and 230°C in a low-oxygen environment. This alters the structure of the wood, reducing its moisture absorption and improving its resistance to shrinkage and swelling. In addition, because the wood absorbs less moisture, it becomes less susceptible to fungi and insects.

Thermally modified wood therefore offers significant advantages over untreated wood, including improved durability, stability, and resistance to external influences.

Properties of Thermowood

Thermowood is known for its unique properties, making it an attractive choice for façade cladding. It has increased dimensional stability, meaning it is less prone to shrinkage and swelling. This makes the wood ideal for outdoor applications where it is exposed to changing weather conditions. In addition, it offers several other advantages:

  • Very lightweight: approximately 400 kg per m³. This equals about 7.2 kg per m² for 18 mm thick façade cladding.

  • Stable: highly dimensionally stable because the wood hardly moves anymore.

  • Fast and even greying: it weathers evenly over time.

  • Easy installation: because it is relatively soft, you can easily install it yourself on the façade.

  • Fire class D: the wood can be treated with fire-retardant impregnation to achieve fire class B.

Moreover, thermowood offers improved durability, with enhanced resistance to moisture, fungi, and insects.

Applications suitable for thermally modified wood

Thermally modified wood is highly suitable for use as façade cladding. Unlike hardwood, which is less recommended for various reasons, thermowood offers an excellent alternative. The wood is available in the same durability classes as hardwood, making it a sustainable choice.

Thermowood is dimensionally stable and has good resistance to moisture and other external influences. It also has a warm color and provides good insulating properties. As façade cladding, thermowood is available in various color tones and profiles, giving every façade a unique appearance.

Ayous (Abachi) and Fraké are wood species that are widely used. In addition, Housewood has completed projects using thermally modified Radiata Pine, Ash, Poplar, Spruce, Pine, Bamboo, and Oak.
