Supplied using locally sourced, heartwood of Scottish Larch, Russwood’s Scotlarch® is a sustainable, durable and cost-effective cladding solution. Frequent knots give Scotlarch® a characterful appearance which is perfectly suited to more rustic and traditional aesthetics in ‘board on board’ and other simple arrangements.
Sorted and regraded in-house, ensuring that all boards are sapwood free on exposed faces for enhanced durability.
In ideal conditions, Scotlarch® will weather to a muted shade of silver/grey.
Sustainably sourced from well managed forests, within around 100 miles of our Highland sawmill. FSC®-certified.
Can be factory coated in SiOO:X original or pigmented versions, to achieve a weathered look at an accelerated rate.
Naturally durable (Class 3 BS EN 350-2).
We do not recommend painting Scotlarch.
