Carbonized wood, also known as thermally modified wood or charred wood, has several benefits when used in saunas. Here are some of the advantages:
-
Stability and Durability: Carbonized wood has improved dimensional stability compared to untreated wood. The thermal modification process alters the wood's cellular structure, reducing its moisture content and making it less prone to warping, shrinking, or swelling. This enhanced stability ensures the wood retains its shape and quality even in the high humidity and temperature fluctuations of a sauna environment.
-
Resistance to Decay and Insects: The carbonization process alters the wood's chemical composition, making it more resistant to decay-causing organisms, such as fungi and bacteria. The modified wood is less susceptible to rot, mold, and insect infestations, which is especially beneficial in the hot and humid conditions of a sauna.
-
Heat Insulation: Carbonized wood has improved thermal insulation properties compared to untreated wood. It can retain heat more effectively, helping to maintain a consistent and comfortable temperature inside the sauna. This property contributes to energy efficiency and reduces the energy required to heat the sauna.
-
Enhanced Aesthetic Appeal: Carbonized wood has a unique and appealing appearance. The charring process creates a dark, rich color that can add a touch of elegance and sophistication to the sauna's interior. The distinct grain patterns and textures of the wood are also more pronounced, providing a visually striking and natural ambiance.
-
Reduced Resin and Odor: The carbonization process eliminates most of the wood's resin, which is responsible for releasing odors when heated. This results in a sauna experience with reduced or minimal scent, allowing occupants to fully relax and enjoy the sauna without any unpleasant odors.
-
Environmental Sustainability: Carbonized wood is typically produced from sustainably sourced materials, and the thermal modification process itself is considered environmentally friendly. The process involves using high temperatures and steam, with no additional chemicals or preservatives, minimizing the ecological impact compared to alternative treatments.
