Retail Prices From Just £11.32 + VAT

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 classic TLAC tongue and groove profile, it delivers an incredibly robust, deeply interlocking facade. 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 TLAC profile is explicitly designed to solve complex commercial installation challenges requiring extreme structural rigidity. Because the interlocking tongue actively seats deeply into the groove, the boards physically lock together. This creates an incredibly strong mechanical barrier that massively reduces independent board movement.

Because our master machinists utilise strictly heavy duty carbide tooling, the 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, seamlessly marrying rugged timber strength with exceptionally clean architectural lines.
