Our 11mm oriented strand board (OSB) provides strength, versatility, and value - ideal for structural and non-load-bearing projects. With great screw-holding ability and an easy-to-paint surface, 11mm OSB 3 offers DIY-friendly fabrication. Boards can be cut, routed, and fastened using standard woodworking tools. Can be paired with timber frames for added reinforcement.

We only supply OSB/3 sheets. This means they are load-bearing boards for use in humid conditions.

Please note: OSB is a structural-grade board designed primarily for construction use. Boards may arrive with printed manufacturer stamps on one face. For aesthetic projects, you can simply use the reverse side of the board.

Frequently Asked Questions

What does OSB stand for?

OSB stands for Oriented Strand Board.

Is OSB water-resistant?

Most OSB is water-resistant, due to the construction process using wax, resins and wood strands. For truly waterproof OSB however, we recommend adding a waterproof coating.

Will OSB hold screws?

Yes, OSB can be screwed and nailed to any surface, as long as you have enough screws to fix it in place.

Is OSB stronger than Plywood?

OSB is 2 times stronger than plywood in shear. Generally, however, OSB and Plywood have a similar load strength.

What is OSB 3?

The term OSB/3 is used to describe a type of OSB, as follows: "load-bearing boards for use in humid conditions". This is defined in BS EN 300.
