2440 x 1220 x 18mm OSB 3 Conditioned Sheets

Conditioned OSB or Oriented Strand Board, also known as 18mm Sterling Board is a versatile, tough, low cost, structural building board for use in accordance with EN13986. Precision engineered with no knots and no voids. Manufactured by laying strands of wood in cross-oriented layers which are then bonded together using an ECO resin. A structurally sound sheet is then formed. This multi-purpose board can be used internally and externally in many applications.

As it's suitable for use in dry, humid and wet conditions it makes the ideal choice to be used for flat and pitched roof applications.

Specifically complies with standards: EN 300, BBA, BS5268, Euro Code 5

There are many frequently asked questions when it comes to the uses for OSB 18mm. Here are the most popular:

Is 18mm OSB 3 suitable for a roof?

It can be used on both flat roofs and pitched roofs. If using on flat roofs, the joists must have centres no more than 400mm apart unless the sheets are being laid in conjunction with other layers of suitable boarding.

Is 18mm OSB 3 water-resistant?

Yes, it is water-resistant and is the ideal solution to be used in pitched and flat roof systems. When using in such systems, it forms part of the overall structure which is combined with roofing membranes, roof coverings such as slates or EPDM.

To further protect the boards from water and moisture when used as part of a wall structure, suitable sealers can be applied.

Can I use OSB 18mm for flooring?

For any other flooring applications with joist centres up to 400mm, then 18mm can be used. For joist centres above 400mm, it would be advisable to use 22mm P5 Chipboard Flooring. If using in areas such as loft space that is used for occasional storage, it would be fine to use at centres above 400mm providing care is taken to walk on the areas that have screws or nails in a line. This means there will be supporting timbers underneath to take the weight.
