Precision-machined from acetylated Accoya timber, this profile delivers flawless interlocking joints and a refined, contemporary finish that stands up to the elements year after year.
Through a revolutionary acetylation process, Accoya timber is molecularly modified for outstanding durability and dimensional stability. Unlike traditional softwoods, it resists rot, decay, and insect attack naturally without toxic chemical preservatives. The result is a Class 1 durable, low-maintenance material that performs exceptionally even in the most demanding outdoor environments.
The Tongue & Groove (T&G) profile ensures a smooth, continuous surface with hidden fixings and clean lines, creating a polished, modern appearance suitable for both exterior faades and interior feature walls. Its subtle, pale blonde tone can be left to weather gracefully into a silvery-grey patina or finished with your preferred stain or coating for a custom look.
