11mm OSB Smartply Full Board

• Firstly, 11mm thickness gives the stability you need for structural sheathing, boarding and light decking.
• Next, the full-size board covers large areas quickly, so you reduce joints and save time.
• Additionally, a smooth and consistent surface accepts screws and nails cleanly and finishes well.
• Finally, great value means you get dependable performance at a lower cost than many plywood options.

Use this board for roof decking and sarking, timber-frame and wall sheathing, floor overlays and subfloor repairs, plus site hoardings, packaging, shelving and general carpentry. Because the board is easy to handle, small teams can cover large areas quickly.

Before you start, acclimatise the sheets on site. Then leave the recommended expansion gaps, and finally seal cut or exposed edges in wet zones. The board accepts wood screws, ring-shank nails and common adhesives. For guidance, many installers work at 150 mm centres on supported edges and 300 mm in the field, with 3 mm between boards and 10 mm at walls. Always follow your designer’s specification and current building regulations.

SmartPly sources fast-growing timber from responsibly managed forests. Consequently, you reduce waste without sacrificing performance. Choose this eco-friendly panel when sustainability matters as much as strength.
