Why do we make saunas only from thermowood?

When buying a sauna, the most important thing is to choose its construction material - ordinary pine or thermally treated pine.

Thermowood production technology is based on heating wood at a temperature of 160-220°C. During the heating process, the OG cells of the wood fibers change – the sugar in the wood is broken down, as a result of which it gains incomparable benefits.

Advantages of thermal wood:

• Resistance to rot - thanks to the greatly reduced hemicellulose, which is food for rot, the life of the wood is up to five times longer than untreated wood.

• Stability - with a lower equilibrium humidity, the radial and tangential decay of wood also decreases, which allows the use of longer and wider materials;

• Discoloration – the wood acquires color throughout, and the discoloration depends on the treatment duration, temperature, but the color can vary from light brown to chestnut brown.

• Thermal conductivity – thermal wood has about 20-25% less thermal conductivity than untreated wood and is therefore perfect for saunas.

• Resin - it evaporates as a result of the thermal process, and this material is friendly for saunas, because resin can burn you.

The most important feature is stability, normal wood changes in size (increases) by absorbing moisture up to 3%, while thermal wood only up to 1%.

With a barrel-shaped sauna with a circumference of 8.5 meters, using ordinary pine, the maximum size increase will be 25.5 centimeters, as a result, splits may form and the hoops need to be adjusted before summer and autumn.

For thermal wood barrel-shaped saunas, the hoops perform only a decorative function, and we give a guarantee for all glass elements.
