OSB Board

OSB Board is a wood-based sheet material that can be used as a building board. It is durable and versatile, making it a popular choice. OSB flooring can be used for flooring within workshops and sheds and it has also been known for OSB sheets to be used in its rawest form within restaurants and bars to create a rustic look.

What is OSB Board?

OSB Board was originally introduced into the market as an alternative to plywood and is made with wooden strips positioned using a cross-grain technique. This design also ensures that the board is less likely to warp or split. It is also capable of handling more stress and is stronger and more stable than alternatives.

For further details regarding the structure of OSB Boards, please refer to the Wood Panel Industries Federation’s (WPIF) guide.

OSB Grading

OSB is available in two grades, both of which are suitable for structural use:

OSB2 can be used only in dry conditions and for non-load bearing applications including site hoardings, packaging, such as crates and pallets, DIY, shelving, sheds and exhibition displays.

OSB3 can be used in both dry and humid conditions in both commercial and domestic situations. It can be used for all of the applications that OSB2 can be used for, plus it can be used as flooring, wall sheathing, timber frames, agricultural buildings and roofing (both pitched and flat).

OSB Board is FSC certified, meaning that all materials were taken from sustainable sources.
