Secure immensely strong, highly structural architectural timber directly from our advanced Somerset milling facility. British Douglas Fir is celebrated globally for its phenomenal impact resistance and beautiful, striking reddish-pink heartwood. When strictly machined into the highly decorative TLAV shiplap profile, it delivers a stunning scalloped shadow line alongside deeply interlocking structural security. By specifying this 100% sustainable, homegrown timber, you actively slash the carbon footprint of your commercial development while securing a facade built to withstand severe environmental exposure.

Mechanical Profile Advantages

The highly versatile TLAV shiplap profile is explicitly designed to solve complex commercial installation challenges requiring extreme structural rigidity alongside classic aesthetics. The beautifully scalloped curve ensures rapid exterior moisture run-off, while the underlying tongue locks deeply into the corresponding groove to massively reduce independent board movement.

Because our master machinists utilise strictly heavy duty carbide tooling, the incredibly dense Douglas Fir is cut absolutely perfectly without grain tear-out. This precise dimensional accuracy actively ensures a completely seamless installation across expansive commercial elevations, flawlessly marrying rugged timber strength with refined architectural detailing.
