  • Zero-added formaldehyde means a board that’s more environmentally friendly and consistent.
  • Cut waste with panels sanded and machined to exact tolerances. That way, you get the same high quality boards, with no knots, voids or delamination problems.
  • Don’t let the weather hold you up. Construction can go on with structural panels that perform even when it gets a bit wet.
  • Perfect for platform floors, with a hardwearing tongue and groove profile that’s precision engineered to deliver.
  • Tough enough to meet most load-bearing applications, SterlingOSB Tongue & Groove is BBA Approved and recognized by NHBC Technical standards, for housing applications.
  • Work with a sustainable timber building product that’s FSC® certified and made from timber grown in the UK. It’s manufactured here too, meaning fewer carbon miles clocked up in transportation.

SterlingOSB Zero Tongue & Groove has the following certifications:


The FSC® product label allows consumers worldwide to recognise products that support the growth of responsible forest management. In an increasingly environmentally aware marketplace many demand the FSC® mark on their wood products: with West Fraser it comes as standard.


The BBA (British Board of Agrément) is designated by UK Government to issue European Technical Approvals. This provides third party security and further guarantee of SterlingOSB Zero Tongue & Groove performance in modern construction applications.
