ABC of Thermowood: What is it and why choose it?

The appeal of Thermowood lies in its superior performance and reduced environmental impact. As awareness of eco-friendly building materials grows, thermally modified wood emerges as a sustainable alternative to chemically treated timber. By using only heat and steam in its production, Thermowood avoids harmful chemicals often found in wood preservation. This article will explore the remarkable properties of Thermowood, its various applications in the construction industry, and the reasons it should be considered for any building project.

The transformation of ordinary timber into Thermowood takes place through a meticulous process. Wood is subjected to elevated temperatures of 180-230°C in an oxygen-free environment, leading to significant changes in its characteristics. One primary benefit of this thermal modification is a reduction of approximately 50% in the equilibrium moisture content (EMC), which helps the wood to maintain its form and resist warping, swelling, or shrinking in different environmental conditions.

Research has shown that the dimensional stability of Thermowood improves up to 15 times compared to untreated wood, allowing it to endure moisture-related challenges typically faced in construction. Moreover, the density decreases by 10-15%, resulting in a lighter material without compromising durability. Enhanced properties of Thermowood include a more than 50% increase in compression strength, making it robust and resilient.

Another significant advantage is Thermowood's increased resistance to decay and fungi, which can extend its service life by up to 25 times that of untreated wood. Changes at the molecular level, such as the removal of hydroxyl groups, contribute to its reduced ability to absorb water and increased overall durability. The captivating darkened appearance of Thermowood enhances its aesthetic appeal, making it an attractive choice for various applications.

Choosing Thermowood equates to selecting a sustainable option in building materials. The production process is notable for its reliance solely on natural elements—heat and steam—while avoiding harmful chemicals associated with traditional wood treatment. This chemical-free approach offers a healthier alternative to conventionally treated timber, appealing to environmentally conscious consumers.

According to research from Tantimber, Thermowood's cradle-to-gate greenhouse gas emission stands at an impressive -653 kg CO2 equivalent per cubic meter. This positive environmental impact is enhanced by the low lifecycle emissions associated with Thermowood, which can significantly contribute to lowering overall carbon footprints in construction projects.

Minimal greenhouse gas emissions produced during Thermowood's lifecycle positively affect sustainable building certifications such as LEED and BREEAM. This relevance resonates with builders and projects working to meet stringent environmental standards. Thus, choosing Thermowood aligns with both ecological considerations and the demands of high-quality construction practices.

The adaptability of Thermowood is evident in its extensive applications across various areas of construction and design. Its enhanced durability and stability make it well-suited for exterior cladding, decking, and sauna interiors. With a proven history in modern architecture, Thermowood's resistance to moisture and environmental degradation positions it favorably compared to conventional materials.

Beyond exterior applications, Thermowood can be used in high-humidity environments like bathrooms and kitchens. Its natural aesthetic enhances the design of both residential homes and commercial buildings. Furthermore, Thermowood’s flooring options combine excellent moisture resistance with visual appeal, offering a long-lasting and low-maintenance alternative.

Thermowood cladding presents distinct advantages over conventional painted wood, including greater stability, water repellency, and a desirable finish without the need for chemical coatings. Its aesthetic flexibility makes it compatible with various architectural styles, capturing the attention of architects and builders seeking both sustainable and effective materials.

The successful implementation of Thermowood in numerous projects highlights its potential across both residential and commercial sectors. Prominent examples demonstrate its adaptability and performance under various conditions. For instance, the St. Petersburg Pier in Florida employed Thermowood for rainscreen siding, showcasing extraordinary resistance to high winds while maintaining visual appeal.

Another notable case, the Thermowood House designed by Teź Architekci, integrates this material seamlessly into the surrounding environment, emphasizing both durability and insulation properties. Such projects illustrate how Thermowood exceeds traditional building materials, providing not only aesthetic qualities but also practical benefits such as longevity and minimized maintenance.

These success stories consistently demonstrate the benefits of employing Thermowood, reinforcing its growing presence in the construction industry and highlighting a progressive shift toward sustainable building practices.

Current market trends reveal a rising preference for Thermowood, resonating with global shifts toward sustainability. The market is projected to grow significantly, with estimates indicating a valuation of USD 6.73 billion by 2031, reflecting an annual growth rate of approximately 8.1%. This trend is largely driven by heightened awareness of eco-friendly construction materials.

Certifications such as LEED and BREEAM have positioned Thermowood at the forefront of sustainable building initiatives. The material not only fulfills modern architectural needs in terms of aesthetics and functionality but also meets the demand for environmentally sound practices. Urban development projects increasingly incorporate Thermowood into parks and public spaces to promote greener lifestyles.
