Builders Sheet Materials


We stock a full range of quality sheet materials – including OSB and chipboard – for your construction projects.

Also known as flakeboard, sterling board and aspenite, Oriented Strand Board (OSB) is a kind of manufactured board made from thin, rectangular strips of machine-cut wood that are compressed and bonded together. The resulting product is stronger than milled timber and has many uses in DIY and the building trade. OSB comes in a variety of types and thicknesses and is particularly suitable for load-bearing applications. There are four different grades of this material which have been defined in terms of their mechanical performance and resistance to moisture. OSB2 are load-bearing boards for use in dry conditions and OSB3 are more suitable for humid conditions.

At RGC Building Supplies, our OSB2 is a high-performance sterling board and it offers powerful dimensional stability and load-bearing strength in dry conditions. Its applications include shelving and platform construction, pallet manufacture, packaging, boarding-up, signboards, upholstered furniture frames, shopfitting, bar and hotel fitting and exhibition stands. We supply 11mm-thick OSB2 in 2440mm x 1220mm sheets, but we will be pleased to help with other sizes on request.

Our OSB3 has proven stability and load carrying capability, and it's conditioned for humid environments. OSB3 is most commonly used in roofing, sarking, site hoardings, timber frame buildings and in flooring. Our OSB3 is 18mm thick and comes in 2440mm x 1220mm sheets. Again, other sizes are available on request.


Particleboard or chipboard is made by mixing wood particles or flakes together with a resin and forming the mixture into a sheet. The result – which is available in different densities – is a durable sheet material that is easily worked and quick to install. It is an economical product which is particularly suited for use in domestic flooring, although other types of chipboard are used in lightweight furniture and counter tops. We stock moisture-resistant T&G chipboard for use in flooring in 2400mm x 600mm x18mm and 2400mm x 600mm x22mm.
