T&G Shiplap Tanalised timber combines a tongue and groove profile with a weather-shedding shiplap overlap for a clean, close-fitting finish. The 19mm nominal board (finished 15mm x 119mm) is pressure treated to resist rot, decay and insect attack.
Ideal for sheds, summerhouses, cabins, garages, fencing panels and exterior walls, it provides a smooth surface that is easy to paint or stain. The traditional shadow-line profile adds visual interest while effectively directing water away from the structure.
