9mm OSB Smartply Cut to size

• Firstly, 9mm thickness suits sheathing, hoardings and light roofing/flooring tasks.
• Next, custom cutting means no on-site sawing—panels arrive ready to fix.
• Additionally, a smooth surface accepts screws, nails and adhesives and finishes well.
• Finally, great value compared with plywood.

Site hoardings, wall panels and sheathing, roof sarking, furniture backs and shelving, sheds, boxing-in and general joinery. A 9mm OSB board is ideal for these lighter applications where a thinner, stable panel is the practical choice.

Enter your width × length at checkout and add the quantity for each size. If you’re fitting into a frame, allow for clearances and expansion gaps. Need layout help? Send your cut list and we’ll suggest the most efficient panel optimisation.

Acclimatise, leave expansion gaps, and seal edges in wet zones. Practical fixing: 150 mm on edges, 300 mm in the field, 3 mm between boards, 10 mm at perimeters. Follow your spec.
