Product Details

OSB3 T&G Sheets are an ideal application for this tough, versatile material.  The product is manufactured to the same standard as OSB3 but with the addition of tongue and grooved edges. These OSB3 sheets are precision-engineered tongued and grooved board for use in flat roof decking and flooring applications.  They are designed to perform in humid conditions, consequently making them ideal for house building and construction.

Benefits of OSB3

Firstly,  OSB3 is stronger than most softwood plywood, thanks to the tens of thousands of real wood strands that go into every board.   The OSB3 panels  are sanded and machined to exact tolerances. Therefore the standards are consistent with high quality boards, no knots or voids and no delamination problems.  Perfect for platform floors, with a hard-wearing tongue and groove profile that’s precision engineered.

Construction can go on with structural panels that perform even when it gets a bit wet.  OSB3 is 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.  OSB3 is a sustainable building product that’s FSC certified and made from UK grown timber. Finally OSB3 T&G Sheets are manufactured here in the UK meaning fewer carbon miles used in transportation.
