Specifications

Installation

Install Bangkirai boards on a strong, ventilated subframe designed for hardwood applications. Pre-drilling is strongly recommended due to the density of the wood. Always use stainless steel A2 or A4 fixings to prevent corrosion and staining. Ensure proper ventilation behind the cladding for long-term stability.

Maintenance

Bangkirai is naturally durable and can be left untreated to weather to a silver-grey patina. For colour retention, apply a high-quality hardwood oil periodically. Clean the surface regularly to remove dirt and organic deposits.
