Specifications

Installation

Install the boards onto a straight and ventilated timber subframe to ensure long-term stability and performance. Maintain sufficient airflow behind the cladding and use stainless steel or corrosion-resistant fixings to prevent staining. Allow the wood to acclimatise before installation for best results.

Maintenance

Thermally modified wood requires minimal maintenance due to its improved stability. For exterior use, a UV-protective oil can be applied to preserve the natural colour. Without treatment, the wood will gradually weather to a silver-grey patina over time.
