Thermowood Tongue and Groove (T&G) cladding provides a durable and sustainable solution with a sleek, seamless finish. Manufactured through a heat-treatment process, Thermowood is naturally resistant to rot, decay, and insects, offering an eco-friendly alternative to chemically treated timber.

The T&G profile ensures a tight, interlocking fit, delivering excellent weather resistance and a smooth, refined appearance suitable for both traditional and contemporary designs. Thermowood’s enhanced stability minimizes warping, swelling, and shrinking, guaranteeing a consistent, high-quality finish over time.

Treatment

Untreated, Redwood Thermowood offers excellent durability and natural resistance to decay and insects, making it an ideal choice for external use. Its enhanced thermal modification process improves its stability and resistance to weathering, ensuring reliable performance in exposed outdoor environments.

To maintain its natural appearance and extend its lifespan, we recommend applying a suitable wood oil or stain, such as OSMO. This helps to preserve its rich, warm tones while providing additional protection against cracking and the effects of UV exposure. Staining enhances the timber's durability, ensuring it retains its structural integrity and aesthetic appeal over time, making Redwood Thermowood a reliable and long-lasting option for outdoor projects.
