Wood has always been one of the most important building materials – combining natural beauty, warmth, and versatility. Traditional wood, while aesthetically pleasing, requires regular maintenance and often struggles under extreme weather conditions. At BHB Bertsch HolzBau, we rely on ThermoWood – thermally modified wood, which, due to its exceptional properties, has become our top choice for manufacturing decks for our wooden houses.
Since we manufacture our ThermoWood decks in-house, we maintain full control over the quality and aesthetics of the final product. The raw material is sourced exclusively from renowned sawmills in Finland, a country known for its high-quality wood processing standards and pristine forests.
What is ThermoWood?
ThermoWood is wood that undergoes a special thermal modification process, which completely transforms its physical, chemical, and aesthetic properties. The process is carried out in a controlled atmosphere at high temperatures, without any chemical additives. The result is a material that is:
- Highly resistant to moisture and changing weather conditions,
- Dimensionally stable – it does not shrink or swell like untreated wood,
- Naturally resistant to mold, fungi, and insects,
- Eco-friendly – the process requires no chemical treatments,
- Visually appealing – it retains the natural grain of the wood, and its color gradually develops an elegant patina over time.
How is ThermoWood Made?
The thermal modification process involves several steps:
- Pre-drying – the wood is dried to the appropriate moisture content to prepare it for thermal treatment.
- Heating in a steam atmosphere – the wood is exposed to high temperatures (180–220°C), which changes its chemical structure.
- Cooling and stabilization – the wood is slowly cooled, resulting in enhanced durability and dimensional stability.
The final product is stronger, harder, and more resistant to external factors than conventional wood, while maintaining its natural appearance.
Why ThermoWood is Ideal for Decks
A deck is a special space – it combines functionality, aesthetics, and comfort. The wood used for our decks must meet several critical requirements:
1. Weather Resistance
Decks are exposed to rain, snow, frost, sun, and temperature fluctuations. ThermoWood is resistant to moisture absorption, significantly reducing the risk of cracking, warping, or blistering.
2. Dimensional Stability
Traditional wood often shrinks or swells due to changes in humidity. ThermoWood maintains dimensional stability, ensuring the deck stays even and safe, and the boards do not “move” unpredictably.
3. Resistance to Pests and Fungi
ThermoWood is naturally resistant to biological attacks – fungi, mold, and insects cannot develop in it. This ensures a long-lasting deck without the need for chemical treatments.
4. Eco-friendliness and Safety
At BHB Bertsch HolzBau, we prioritize healthy and ecological solutions. ThermoWood is processed entirely thermally, without chemical additives, making our decks fully safe for residents, children, and pets.
5. Natural Beauty
ThermoWood preserves the texture and character of natural wood, giving decks elegance and warmth. Over time, the wood develops a subtle patina that enhances charm and highlights the natural character of your outdoor space.
