Product Overview
Shiplap treated timber cladding, measuring 25mm x 150mm nominal (finished size 21mm x 144mm), supplied by the metre in random lengths from 2.1m to 5.1m. Designed for exterior structures, this board combines wide coverage with durable pressure-treated protection.
Manufactured from softwood that has undergone preservative treatment, the timber is safeguarded against decay, moisture ingress, and insect attack. This process extends longevity and reduces ongoing maintenance.
The shiplap tongue-and-groove design features a precise interlocking fit with overlapping edges, ensuring both weather resistance and a clean decorative finish. The increased finished width of 144mm allows for faster coverage across large wall areas.
Ideal for cabins, summerhouses, and larger outdoor buildings, this profile balances strength, coverage, and appearance.
