Description
Iroko is one of the most sought-after hardwoods for premium exterior cladding, prized for its rich colour, natural oils and impressive strength. Sourced from West and Central Africa, Iroko has been used for generations in shipbuilding, high-end joinery and architectural projects, thanks to its ability to perform in harsh outdoor conditions while maintaining its beauty.
Our 145mm x 19mm Iroko Planed Square Edge (PSE) boards offer a clean, modern option for timber cladding and exterior finishing. The square edge profile is perfect for contemporary designs, creating crisp horizontal or vertical lines with a minimalist, architectural feel.
Iroko’s natural density and built-in oils give it outstanding resistance to moisture, rot and insects without the need for pressure treatment. When freshly installed, the timber displays beautiful golden to medium brown tones, which slowly mellow into a soft silver-grey patina if left untreated. Many customers choose to apply a quality wood oil or OSMO stain to preserve the warm colour and enhance surface protection.
This profile is ideal for modern façades, garden rooms, outdoor buildings, feature walls and bespoke architectural projects where a refined, high-quality timber finish is required.

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.
