Description
These 2.4m 144mm x 19mm Iroko Shiplap cladding boards are a premium hardwood option for exterior projects where appearance and performance really matter. Iroko is a naturally oil-rich African hardwood, widely used in high-end joinery and exterior architecture thanks to its ability to perform in demanding outdoor conditions without the need for chemical treatment.
The shiplap profile creates a subtle overlapping joint that improves water run-off and adds a clean shadow line, giving walls a sharp, modern finish. With a 135mm face coverage, these boards provide excellent coverage while still delivering strong visual definition.
Freshly machined Iroko displays beautiful golden to medium brown tones, which naturally weather to an elegant silver-grey over time. To keep the warm colour for longer and add extra surface protection, we recommend using a high-quality wood oil or OSMO stain.
This profile is ideal for garden rooms, sheds, modern façades, outbuildings and architectural feature walls where you want a refined hardwood finish that will age gracefully.

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.
