OSB

Oriented Strand Boards (OSB Sheets)

Oriented strand board, or OSB for short, is a versatile, cost-effective type of building board. The material is a combination of wood flakes or timber strands, bonded together with a special resin. This very strong, reinforced sheet material is similar to plywood in many ways, but OSB board is generally less expensive, on average.

You could argue that OSB sheets bear similarities to lightweight plywood with only difference being in the manufacturing process. Common uses for OSB include flooring, roofing, shelving, furniture and sheathing in walls. On the whole, an OSB panel makes a very rigid structural or non-structural use in dry, interior conditions, with many boards, such as 18mm OSB (3) being able to withstand large amounts of moisture.

The best sealer for OSB (to make it water resistant) would be a general exterior sealant. Water does pose a risk to the edges of OSB board and therefore a good quality OSB sealer will act as a perfect protective measure.

As mentioned, the average OSB cost is less than that of other waterproof boards like chipboard, and our prices mean you can still get high quality and yet still great OSB materials for terrific value.
