Advantages of Thermo Wood: Why Choose Thermally Modified Wood?

Thermally treated wood is natural wood that is treated in a special environment at high temperatures without the use of any chemicals to significantly improve its properties. During treatment, the moisture content is reduced and the structure of the wood cells is changed, making it more resistant to environmental influences, deformation, decay, and microorganisms.

One of the biggest advantages of thermowood is its durability. Thermally treated wood is highly resistant to moisture, temperature fluctuations, mould, and fungi. This is particularly important in Lithuania’s climate, where changeable weather and seasonal changes can have a significant impact on ordinary wood. 

These properties make thermowood ideal for outdoor use – for facades, terraces, gazebos, or fences. Unlike untreated wood, thermowood does not shrink, warp, or have a high tendency to crack or rot. 

Heat-treated wood acquires a richer, warm brown hue, lending it a natural elegance. This colour depends on the temperature and duration of treatment—the higher the temperature, the darker the wood. In addition, the colour is more uniform than that of untreated wood, and the surface becomes softer and smoother. 

When choosing thermo ash, you can enjoy an exceptionally luxurious, dark wood tone that blends perfectly with both contemporary and classic designs, while thermo pine is lighter but also retains its shape and structure. Both types of wood are highly valued for their appearance and ease of processing. 

One of the most important criteria for consumers today is sustainability. Thermo wood meets high ecological standards because no chemicals are used in its production, and all of its properties are achieved naturally, through heat and steam. This means that thermo wood is safe to use even in places such as children’s playgrounds, bathrooms, and saunas. Additionally, thermo wood is typically produced from local or certified European wood, which reduces its ecological footprint and contributes to more sustainable forest management.

If you are planning to renovate the exterior of your home or build a terrace, it is worth considering thermally modified wood for the façade. This type of wood not only looks great, but also lasts a long time without additional impregnation or painting. Of course, over time, the surface will naturally change colour, but this is an aesthetic rather than a technical feature. To maintain the original shade, the surface can be periodically coated with an oil containing a UV filter. 

Another popular trend is thermally modified wood decking. Such boards are not only durable but also pleasant to walk on barefoot, as they do not contain resin, are less slippery, and have a smooth surface. Additionally, they retain less heat in the sun compared to composite materials or metals, making them ideal for summer outdoor recreation.

Thermo wood is a highly convenient choice for those who value aesthetics but do not want to constantly worry about maintenance. Due to its lower moisture absorption and structural stability, thermo wood requires minimal maintenance. Although periodic surface renewal with oil or cleaning is recommended, frequent impregnation or pest protection is no longer necessary. This means lower long-term costs and less hassle during operation – a feature that is particularly appreciated in the long run.

The answer is simple – it is definitely worth it if you are looking for a durable, aesthetic, environmentally friendly, and low-maintenance solution. Whether you plan to build a new terrace, renovate a façade, or are looking for natural materials for your interior, thermowood is a valuable investment in quality and durability.
