Thermowood, or thermally modified wood, is prized for its durability, stability, and resistance to moisture, insects, and decay. The thermal modification process involves heating wood to high temperatures—typically between 160°C and 230°C—in a controlled environment to alter its internal structure. This process removes moisture and breaks down sugars that attract fungi and insects, making the wood ideal for exterior cladding, decking, saunas, and other demanding applications. While traditional thermal treatment is effective, microwave technology introduces a new level of precision, efficiency, and environmental safety to the production and performance of Visit Online shashel for More details..
Microwave technology uses electromagnetic waves to directly heat the water molecules inside wood. Unlike conventional heating, which starts at the surface and moves inward, microwaves penetrate deeply and uniformly, ensuring the entire piece is evenly treated. This method enhances the Thermowood process in several key ways.
First, microwave-assisted thermal treatment reduces drying time significantly. Traditional kiln drying for thermally modified wood can take several days, especially for thicker cuts. Microwave drying, by contrast, can reduce the same process to hours. Faster drying means lower energy consumption, which results in a more efficient and eco-friendly production cycle.
Additionally, microwaves allow more consistent treatment across the wood’s core and surface. In traditional thermal processes, the core of thicker wood pieces may retain moisture or uneven temperatures, leading to cracks, internal stress, or underperformance in outdoor conditions. Microwave heating solves this by delivering energy throughout the entire volume of wood, reducing the chance of uneven modification and improving structural integrity.
Microwave technology also supports greater control over the modification process. With adjustable settings and real-time temperature monitoring, producers can fine-tune treatments for different wood species, densities, and intended uses. This level of control is especially valuable when working with hardwoods or specialty woods that respond differently to heat. Consistency is key to achieving Thermowood’s signature properties like dimensional stability, improved insulation, and resistance to swelling or shrinking.
For manufacturers committed to sustainability, microwave treatment offers another major advantage: zero emissions and chemical-free processing. Unlike pressure-treated woods that rely on preservatives, Thermowood enhanced with microwave drying doesn’t introduce any toxins into the wood or environment. It meets the highest environmental standards and is safe for both residential and commercial projects.
Thermowood’s performance is also improved after microwave treatment. The enhanced moisture resistance means it performs better in humid or wet environments. Structures made from microwave-treated Thermowood are less likely to warp, cup, or rot, which extends the life of outdoor decks, façades, garden structures, and more. It’s especially beneficial for applications in spas, saunas, and marine environments where both heat and humidity are constant.
Microwave technology can also be applied as a post-treatment drying or conditioning method for already modified Thermowood. This is useful when the wood has been exposed to rain or humidity during transport or storage. A quick microwave session can restore optimal moisture levels without affecting the wood’s thermal properties or causing surface damage.
In summary, Thermowood benefits greatly from the integration of microwave technology, both in its initial treatment and ongoing use. It enables faster, cleaner, and more precise thermal modification, boosts durability and moisture resistance, and supports the growing demand for eco-friendly building materials. As the construction and restoration industries shift toward greener, smarter solutions, microwave-enhanced Thermowood stands out as a superior choice for high-performance, sustainable wood applications.
