Sterling OSB by Latham Timber

Sterling OSB3 Tongue & Grooved

Back to Products

Tough, consistent and great value, Sterling OSB3 T&G is a precision-engineered tongued and grooved board for use in flat roof decking and flooring applications.

It performs in humid conditions, making it ideal for house building and construction.

Key Features:

  • Stronger than most softwood plywood, thanks to the tens of thousands of real wood strands that go into every board.

  • 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, OSB T&G is BBA Approved and recognized by NHBC Technical and Zurich Municipal standards, for housing applications.

  • Work with a sustainable 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.
