What Is Structural 9mm OSB Board?  

9mm OSB 3 board is a moisture-resistant, structural panel purposed for use in a variety of internal and external applications including roofs, floors and walls.

The 'OSB' in its title (short for Oriented Strand Board) makes reference to its manufacturing process: which sees wood strands strategically oriented and compressed together with adhesive resin. 

9mm OSB comprises multi-layered softwood flakes that are laid in specific orientations and hot-pressed to form a single versatile panel. 

What you’re left with is a strong and durable board that makes a great alternative to plywood, ideal for shelving, sheds, display boards and other domestic uses, as well as commercial applications such as subfloors and roof decking. 

Versatility and affordability can be sustainable too; as proven by 9mm OSB 3. In its manufacturing process, 9mm OSB board utilises younger trees that grow back quickly, unlike ply which uses much older trees.


Where Is Structural 9mm OSB Board Used? 

9mm OSB boards are purposed for a variety of exterior and interior applications, such as wall sheathing, roofing and flooring applications. 

Their strength renders them suitable for load-bearing and structural use, as well as long-term site hoardings due to their moisture-resistant properties. 

As well as being a load-bearing strong board, 9mm OSB boards are also a great product for domestic and decorative applications.

We recommend 9mm OSB 3 for the following applications:

  • Building a garden shed or a summer house - great flooring or wall sheathing solution
  • In shop fittings - to provide racking or exhibition stands for heavy items
  • Wall sheathing
  • Flooring & roofing applications
  • Roof decking
  • Site hoarding
  • Sarking applications


It's important to note before adding these to your project list, that the boards are not 2440mm x 1220mm but 2397mm x 1197mm.


9mm Structural OSB 3 Sterling Board Key Features & Benefits

  • Easy to drill, nail, file and sand (suitable for interior and exterior)
  • The BBA classification permits use in a wide range of commercial and domestic situations
  • Unlike other materials, they do not require fancy equipment or fittings to be installed
  • Used extensively in renovation work and new projects
  • Stronger than chipboard products and non-structural plywoods
  • The boards are manufactured to EN 300 performance standards
  • BBA approved
  • Free of knots and voids
  • Performs well in humid conditions
  • Standard boards have consistent dimensions of 2397mm x 1197mm


For more technical specification depth, please refer to the manufacturer's datasheet.


Using OSB Board in Humid Conditions

9mm OSB board is an engineered sheet material suited to a wide variety of general construction applications. 

Unlike MDF and other interior laminate materials, 9mm OSB board is able to hold its own in humid environments. While the OSB2 board is only suitable for dry conditions, 9mm OSB3 board can withstand more challenging conditions. 

However, this does not mean that the boards are completely waterproof, so as a rule of thumb we always suggest adding further weather protection if you plan to use it for permanent outdoor use.

You can do this by adding weather-proof exterior paint. Follow the exterior paint with a wood waterproofing sealant and allow 12-14 hours for it to dry before installing it - you can add a second coat if required.
