Description
Transform your project with Accoya 144mm x 19mm Tongue & Groove Cladding – a modern, high-performance cladding solution engineered for strength, stability, and timeless appeal.
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.
Superior Performance Meets Elegant Design
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 façades 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.

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.

Right product, right price, right delivery. Sure, it was only one length of cast iron guttering but they took the order seriously, packed it well and kept me updated on delivery. And when I opened the very good packaging I found it was exactly what I had wanted. How can you do better!!
