Brimstone is our thermally modified British timber range, designed specifically for long-lasting, high-performance exterior cladding. We take hardwoods grown in UK woodlands and carefully heat-treat them at around 210°C. The result? Timber that’s naturally durable, impressively stable, and looks clean and refined on a finished building.

If you want a home-grown hardwood with minimal knots, a smooth modern look, and the reassurance of a local supply chain, Brimstone fits the brief. It brings together robust performance, a premium finish, and the environmental benefits of using timber sourced from our own native forests.
