The 18mm Structural OSB3 Sterling Board is a robust, load-bearing panel designed for demanding construction environments. Made from layered wood strands that are arranged for strength and then resin-bonded, it provides a dense, reliable sheet with predictable performance across its entire surface.
Thanks to its OSB3 rating, it can be used in humid or moisture-prone areas where OSB2 would not be suitable. It is frequently chosen for sub-flooring, roof decking, external wall sheathing, timber frame builds and general structural work where rigidity and durability are essential.
The standard 2440mm x 1220mm format makes it compatible with common stud and joist layouts, helping to reduce cutting time and waste on site.
Features & Benefits:
- Structural OSB3 grade suitable for use in humid conditions
- Dense and rigid board designed for heavy-duty load-bearing applications
- Uniform core with no knots, voids or patches of weak grain

- Easy to cut and fasten using standard construction tools and fixings
- Ideal for floors, roofs, sheathing, timber framing and general construction
- Standard sheet size suits common building layouts and simplifies installation
