9mm OSB-3 Structural - 2400 x 1200mm - (FSC® Mix)

9mm OSB-3 Structural (FSC Mix), 2400 x 1200mm OSB (aka Sterlingboard)

OSB-3 is an engineered wood-based sheet material in which strands of wood are bonded together with a synthetic resin adhesive. The outer layers of these panels show how the strands are orientated in a particular direction. We stock SmartPly and Norboard, and large OSB stocks are maintained for collection and/or delivery. 

What is OSB and why use it?

Timbers used in OSB manufacture include both softwoods (spruce, pine) and hardwood (aspen). After drying the flakes are sprayed with a synthetic resin which confers a degree of moisture resistance to the board. OSB will not normally be attacked by wood-boring insects common in temperate climates, but panels made using aspen and spruce are susceptible to fungal attack under prolonged wet conditions. Much of the OSB sold in the UK uses homegrown timber and is also manufactured in the UK and Ireland.

OSB3 Features and Applications

OSB-3 is designed for use where a high performance board is required which provides dimensional stability and load bearing capabilities for use in dry conditions. Strong, consistent and great value, Sterling OSB3 is a precision-engineered board that is stronger and tougher than most softwood plywood, thanks to the tens of thousands of real wood strands that go into every board Each OSB pack contains uniform, high quality boards, with no knots, voids or delaminating problems. Typical applications for OSB2 would include site hoarding, shelving and racking, boarding up, garden sheds, packaging, pallets and DIY projects.

OSB3 is designed for the when the conditions are humid. All OSB boards are easy to saw, drill, nail, plane, file or sand. Nails can be driven as close as 8mm from the panel edge without splitting this sheet material. Typical applications for OSB3 would include timber frame housing, flat and pitch roofing, wall sheathing, flooring, sheds and stables and panelling.

OSB3 Board sizes

OSB 3 is normally stocked in the following thicknesses:
   9mm thick, sheet size 2400mm x 1200mm (metric sized <8' x <4')
   11mm thick, sheet size 2440mm x 1220mm (8' x 4')
   18mm thick, sheet size 2440mm x 1220mm (8' x 4')

• Precision-engineered for structural use in load bearing and challenging conditions.
• It performs well in humid conditions, making it ideal for house building and construction.
• Utilises the whole log for optimum yield.
• Responsibly sourced from managed resources.
• Cut sheet size may vary slightly due to loss of blade width during cutting.

Please note: due to variance in stock and manufacturers, final size of OSB boards may vary between 2400mm x 1200mm and 2440mm x 1220mm.

  18mm thick, sheet size 2400mm x 600mm T&G (8' x 2')

JJoinery, furniture linings, and decorative panelling. The smooth sanded finish provides an excellent base for paint, veneer, or laminate.
Standard MDF is intended for dry internal use only and is not moisture-resistant.
