About this board
Our most ordered OSB: 18mm SmartPly OSB3 in 2440 x 1220 square edge sheets. It has the stiffness for flat roof decks, mezzanines on close joists and heavy-duty wall linings, and its tight faces take fixings near the edge better than most imported boards.
Lay floors and roofs with the long edge across the supports and stagger the end joints. Fifty sheets earn the pallet price shown. The board is not designed for permanent wetting, so roof decks need covering promptly with felt or a single-ply membrane.
