22mm OSB Smartply Full Board

• Firstly, 22mm thickness provides robust structural strength for heavy-duty applications.
• Next, full-size boards cover large areas quickly, reducing joints and installation time.
• Additionally, the smooth consistent surface accepts screws, nails and adhesives and finishes well.
• Finally, great value delivers plywood-like performance at a more affordable price.

Choose 22mm for structural floor decking, roof sarking, timber-frame and wall sheathing, sheds and garden buildings, site hoardings, worktops, shelving and heavy-duty carpentry. Because the panels are easy to handle, small teams can complete larger areas with less waste.

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

SmartPly sources fast-growing timber from responsibly managed forests. Consequently, you reduce environmental impact without sacrificing performance. Pick this eco-conscious 22mm OSB when sustainability matters as much as strength.

1. What is the 22mm OSB SmartPly Full Board used for?
Typical jobs include structural floors, roof decking, wall sheathing, sheds, worktops, hoardings and heavy-duty carpentry.

2. Is it suitable for roofing?
Yes. Install to the designer’s specification with correct support, fixings and a weatherproof membrane. Leave expansion gaps and seal exposed edges.

3. Can I use it outside?
Use it behind cladding or beneath a weathering layer. Do not leave OSB exposed to the weather long-term.

4. Is it structural?
The board offers high strength and stability. For load-bearing applications, follow your structural specification and the relevant standard (many projects specify EN 300 OSB/3 for humid conditions).

5. How do I fix the boards?
Use wood screws or ring-shank nails. A common pattern is 150 mm centres on edges and 300 mm in the field, plus 3 mm gaps between boards and 10 mm at walls.

6. Is it moisture resistant?
Yes. As an OSB3 panel it performs in humid environments when installed correctly; however, protect it from direct, prolonged wetting.

7. Do you offer delivery or collection?
Yes. See our Delivery & Collection information for areas, lead times and charges.
