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.
