Wood Protection in Wooden Houses
Thermally Modified Wood and Shou Sugi Ban Technique Against Woodborers and Rot: Reliable Wood Treatment Methods for Durability of Your Home
Ensuring durability and safety is critically important
Protecting wood is essential primarily to prevent biological damage. Wood is exposed to pests, such as insects (woodboring beetles, termites), fungi (rot, mold), and other organisms that can lead to its destruction. Moreover, it is necessary to protect wood from moisture. Wood actively absorbs moisture, which can cause swelling, deformation, and decay. Additionally, protection against ultraviolet radiation should not be overlooked. Under the influence of sunlight, wood can gradually lose its color and strength over time. Finally, it’s crucial to increase its fire resistance.
Why Choose Environmentally Friendly Methods?
Protecting wood using environmentally friendly methods is important for several reasons:
-
Preserving Human and Animal Health
Traditional chemical wood treatments often contain toxic substances that can harm the health of humans and pets. Such substances may cause allergic reactions, poisoning, and, in some cases, contribute to severe illnesses. Eco-friendly treatments minimize these risks.01 -
Reducing Environmental Pollution
Many conventional wood treatment agents contaminate soil and water as they wash out with rain or break down into harmful chemical compounds. This can have long-term negative effects on ecosystems. Environmentally friendly materials or biological treatments do not harm nature, as they decompose without leaving dangerous residues.02 -
Supporting Biodiversity
Chemical treatments can kill not only harmful insects but also beneficial ones, such as bees and other pollinators. They can also affect animals in the surrounding environment, including birds and fish. Using natural methods helps preserve biodiversity.03 -
Sustainable Development and Responsible Consumption
Using environmentally friendly methods emphasizes the importance of sustainable approaches to construction and the use of natural resources. This aligns with the principles of eco-friendly and socially responsible building, reducing negative impacts on nature and preserving resources for future generations.04 -
Durability and Natural Protection
Eco-friendly treatments often work naturally, strengthening the wood's structure or creating physical barriers for pests. This can provide longer-lasting effects without the need for regular applications of toxic chemical coatings.05
Thermally Modified Wood
Thermally Modified Wood
Thermally Modified Wood (Thermowood) is an innovative material that undergoes a thermal modification process, gaining unique properties. This process involves heating the wood to high temperatures in the absence of oxygen. As a result, changes occur in the wood's chemical composition and physical properties.
The thermal modification process starts with preparing the wood, which is placed in specialized kilns or chambers. The wood is heated to a specific temperature, usually ranging from 160°C to 260°C, in conditions of oxygen absence or low oxygen content. This prevents the wood from igniting and focuses on altering its structure.
During heating, various chemical reactions occur that modify the wood's chemical composition. These include dehydration, the breakdown of glucose and cellulose linear polymers, and the formation of sugars and volatile organic compounds. These changes enhance the wood’s structure and properties.
Thermowood has several unique characteristics:
The production of thermowood using microwave (MW) fields is a new approach that uses electromagnetic radiation to heat wood and alter its structure. This method offers several advantages, including more uniform and faster heating, precise process control, and reduced environmental impact through more efficient energy use. Thermowood produced using this method boasts enhanced strength, stability, and durability, making it a sought-after material in construction, furniture, and other industries.

Features of Thermowood
Thermowood has several unique characteristics:
- Dimensional Stability: Thermowood is highly resistant to deformation caused by moisture or temperature changes.
- Resistance to Rot and Insects: The thermal modification process makes the wood less suitable for fungi, mold, and insects, as its nutritional value is reduced.
- Increased Strength: Thermal treatment can increase the density of the wood and improve its mechanical properties.
- Aesthetic Appeal: Thermowood often has a darker, richer hue compared to untreated wood, making it more attractive for interior and exterior design.
- Eco-Friendliness: The thermal modification process typically does not require chemical additives or preservatives, making thermowood safer for the environment.

Shou Sugi Ban
Shou Sugi Ban
Shou Sugi Ban is a traditional Japanese wood treatment technique that is gaining increasing popularity worldwide for its aesthetic appeal and functional advantages, including protection against rot, moisture, and insects. Although this wood preservation method has ancient origins, it continues to attract architects, designers, and homeowners due to its unique appearance and durability.
Known as "Yakisugi" (焼杉) in Japanese, which literally translates to "burning cedar," the technique typically uses wood species such as cedar, cypress, and pine.
Through the Shou Sugi Ban process, the resulting wood not only boasts a beautiful and durable exterior but also provides additional protection against mold and insects thanks to charring and the charcoal layer.
Today, Shou Sugi Ban is experiencing a renaissance in many countries, including those outside Japan. Modern architects and designers increasingly incorporate charred wood into their projects for its unique appearance, durability, and eco-friendliness.
With the growing interest in sustainable and eco-friendly materials, the demand for Shou Sugi Ban-treated wood is expected to rise in the coming years. Furthermore, as new technologies and processing methods develop, it is likely that even more innovative variations of this traditional practice will emerge, leading to its broader adoption in global architecture and design.
