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
  • Maintains shape well, helping to limit movement and swelling
  • 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
  • 18mm thickness provides enhanced stiffness and support for structural builds
