What is thermowood and why is it important?

We use durable thermo wood for all our Tønsaunas. Thermo wood is kiln-burned wood, making it more durable, stable and resistant to external influences. It is the ideal choice for outdoor saunas due to its ability to withstand temperature changes and humidity. Read more about our thermo wood here.

For the production of our outdoor saunas, unlike other suppliers, we use thermo wood with a thickness of 42 mm for the outer walls and 30 mm for the inner walls of our outdoor saunas. This thickness makes a world of difference in durability and insulation, which is essential for an optimal sauna experience.

Heat and sound insulation: thermowood vs. natural wood

You can see besides outdoor saunas made of thermo wood, that natural wood is also used. The thermal and sound insulation of thermo wood is up to 30% better than that of natural wood. This means that your sauna stays warmer longer and you can enjoy a quieter experience. In other words, the thickness of the wood directly affects the quality of your sauna experience.

How thick should sauna beams be?

You might think that the thicker the wood of the sauna, the better. At a minimum, the wood should be 40 mm thick, but they should also be no thicker than 80 mm. Thicker beams can trap excessive heat and make it difficult for your sauna to breathe, resulting in moisture build-up and possible problems.*

Why is good insulation essential for a sauna?

Good insulation is very important for a sauna for several reasons. First, it ensures that the sauna reaches the desired temperature quickly. Second, it helps maintain heat, saving energy and making your sauna more efficient. Finally, insulation contributes to a more pleasant sauna experience by reducing noise and preventing moisture problems.
