Product Overview

Shiplap treated timber cladding, measuring 25mm x 125mm nominal (finished size 21mm x 119mm), supplied by the metre in random lengths from 2.1m to 5.1m. Engineered for exterior applications, this board delivers additional thickness for greater strength and resilience in demanding environments.

Produced from pressure-treated softwood, the timber is impregnated with preservatives to protect against decay, insect attack, and moisture damage. This ensures long service life with reduced maintenance requirements.

The shiplap tongue-and-groove design creates a precise interlocking fit with overlapping edges, forming a weather-tight seal while delivering decorative horizontal lines. This profile is highly effective in resisting wind and rain ingress.

With increased thickness compared to standard profiles, this version is particularly suited to larger buildings and applications requiring robust exterior cladding.
