Why Choose British Larch T&G Cladding?
British Larch is one of the most durable and visually appealing softwoods available. Its tight grain, natural resins, and strength make it perfect for exterior use where both looks and longevity matter.
Over time, its warm reddish-brown hues fade gracefully to a silvery-grey, creating a timeless aesthetic.
Compared with imported timber, home-grown Larch offers a more open grain and rustic texture, enhancing natural charm while supporting sustainable UK forestry.
