6 Reasons Why Thermowood is the Best Choice for Sauna Materials
Did you know that thermowood is one of the oldest and most environmentally friendly ways to treat wood? The Vikings discovered the power of heat when they coated their boats with tar to make them more durable. Today, the same nature-friendly technology is used but with advanced modern technology.
But what makes thermowood so special, and why should you choose thermowood for your sauna? Here are a few reasons:
What is Thermowood?
When it comes to saunas, durability is crucial. The high humidity and temperature require a material that can withstand the conditions.
Thermowood is wood that has undergone a special heat treatment process. The wood is heated to high temperatures (180-215°C) with water and steam. This irreversibly changes the physical and chemical properties of the wood. The entire process is chemical-free.
The heat treatment removes all nutrients from the wood that fungi, mold, and bacteria crave. Nutrient-poor wood doesn’t attract these, making the wood more stable and durable. The high temperature also releases the resin from the wood, giving the sauna a beautiful finish.
After thermowood treatment, the surface of the wood is soft-textured and has a pleasant aroma. The color is caramel brown, with the intensity depending on the treatment temperature. The higher the temperature, the browner the wood becomes.
Thermowood Endures in All Conditions
Thermowood is specially treated to make it incredibly durable and stable. It is up to 25 times more durable than regular wood. This means your sauna will remain beautiful and functional even in the harshest conditions – whether it’s a cold Estonian winter or a humid summer.
Additionally, thermowood is resistant to moisture and temperature fluctuations, making it ideal for saunas, where constant moisture and heat are the norm.
Chemical-Free, Clean, and Health-Friendly
Thermowood is entirely free of chemicals. Heat, water, and steam – only these three natural elements are used in the treatment process. The result is clean and safe wood that doesn’t contain harmful substances for health or the environment. It’s the ideal choice for those who value a healthy lifestyle and eco-friendly solutions.
Thermowood Retains Heat Well and is Moisture-Resistant
Thermowood retains its natural properties, including excellent heat insulation and moisture resistance. It helps keep the sauna room temperature stable and ensures an even steam. It also doesn’t deform under moisture, which means the sauna will always look as good as new.
Thermowood has a poorer thermal conductivity than regular wood, which means it stays cooler. This is an important feature in saunas, as it prevents the bench from getting too hot.
A Special and Timeless Appearance
Thermowood is not only practical but also visually appealing. Its deep and rich tones add a luxurious and timeless look to any sauna. Over time, the beautiful texture and color of thermowood become even richer.
Protects Nature and Reduces Waste
Thermowood is a sustainable building material. The trees from which thermowood is made absorb carbon dioxide as they grow and store it. When thermowood is ready, it retains the carbon throughout its entire lifespan, preventing its release into the atmosphere.
The longer lifespan of the wood reduces the need for new materials and minimizes waste in construction projects.
Thermowood Provides Peace of Mind
Thermowood is more fire-resistant than other wood materials. Thermowood is classified to the European standard as D-s2-d0. By treating it with fire-resistant substances, its fire safety class can be raised to B (B-s1-d0).
If you are looking for a sauna that is durable, environmentally friendly, visually beautiful, and fire-resistant, a thermowood sauna is the right choice for you.
