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 highly efficient TLAN halflap profile, it delivers incredibly rapid installation and classic weather deflection. 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 TLAN halflap profile is explicitly designed to solve complex commercial installation challenges requiring extreme moisture deflection and rapid assembly on site. The deeply engineered overlapping joints force severe external rainwater to cascade entirely down the external surface, completely protecting the vulnerable underlying cavity from damaging water ingress.

Because our master machinists utilise strictly heavy duty carbide tooling, the dense Douglas Fir is cut absolutely perfectly without grain tear-out. This exact dimensional accuracy actively ensures a completely seamless overlapping joint across expansive commercial elevations, providing incredible weather security alongside rugged timber strength.
