9mm Structural OSB 3 Sterling Board Product Description


9mm OSB board is an engineered sheet material that has a wide variety of general construction applications due to its strength and versatility. OSB stands for Oriented Strand Board. This refers to the fact that the board is made up of wood strands that are compressed together with adhesive resin. This makes these sheet materials strong and versatile.


Good quality OSB boards bring many benefits, and are used extensively in renovation work and new projects for their load-bearing qualities. They are stronger than chipboard products and non-structural plywoods. The boards are manufactured to EN 300 performance standards, and are BBA approved. Standard boards come in the imperial size of 2440 x 1220 (or 8ft x 4ft), and are sold individually.

OSB boards are suitable for a wide range of exterior and interior applications, such as wall sheathing, roofing and flooring applications. Their strength makes them suitable for load bearing and structural use, and they have also been used for long term site hoardings due to their moisture resistant properties.

If you are building a garden shed or a summer house, then OSB panel is a great flooring or wall sheathing solution. Unlike other materials, they do not require fancy equipment or fittings to be installed. OSB boards are easy to drill, nail, file and sand, meaning less off-cuts and therefore less waste.

OSB Board for Humid Conditions

OSB is a the perfect sheet material to use in humid conditions. While the OSB2 board is only suitable for dry conditions, OSB3 can withstand more challenging conditions. Despite this being the case, it is always a good idea to add further weather protection if you are planning to use if for permanent outdoor use. You can do this by adding a weather-proof exterior paint, followed by a wood waterproofing sealant. Allow 12-14 hours for it to dry before installing it - you can add a second coat if required.
