Description
These 4m European Larch Wood Cladding 145mm x 19mm Square Edge (PSE) Boards are a premium choice for exterior timber projects where strength, clean lines, and long-lasting performance are essential. Manufactured from slow-grown Northern European Larch, this naturally durable softwood offers excellent resistance to decay, making it ideal for outdoor use without chemical treatment.
The 145mm x 19mm planed square edge (PSE) profile creates a sharp, modern finish that suits both contemporary and traditional designs. With full 145mm face coverage, these boards are highly versatile and can be used for external wall cladding, fencing, garden buildings, feature walls, and architectural applications.
Supplied untreated, European Larch naturally matures from rich golden-brown tones to an elegant silver-grey patina when exposed to the elements. To preserve its original colour and improve resistance to moisture, UV damage, cracking, and movement, we recommend applying a high-quality OSMO stain.
Each board is precision-machined and planed smooth for easy installation and a professional finish, ensuring excellent consistency across your project.

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.
