Description

Sterling Board 18mm OSB3 2440mm x 1220mm (8′ x 4′)

The 18mm Sterling Board OSB3 is a high-performance, structural sheet material made for strength, stability, and durability. Engineered from layers of oriented wood strands bonded with a moisture-resistant resin, OSB3 provides a reliable alternative to plywood for structural flooring, roofing, and wall sheathing applications.

Each sheet measures 2440mm x 1220mm (8ft x 4ft) — the standard UK size — making it easy to fit, cut, and install across a variety of construction projects. Its OSB3 classification means it is suitable for load-bearing use in humid environments, provided all edges and faces are sealed correctly.
