Installation

Install the boards onto a straight and ventilated timber subframe to ensure long-term performance and durability. Maintain adequate airflow behind the cladding and use stainless steel or galvanised fixings to prevent staining and corrosion. Always allow boards to acclimatise before installation.

Maintenance

Douglas fir is naturally durable but benefits from protective treatment. Apply paint, stain or wood oil to protect against moisture, UV exposure and weathering. Without treatment, the wood will gradually develop a natural silver-grey patina over time.
