OSB is available for structural applications and for non-load-bearings uses. In Europe there are four basic grades available.

Manufacturers also offer variants within these grades, for example, sanded and un-sanded, tongue-and-grooved and plain-edged.

Here is a broad guide to which grade you will need for the job in hand:


General purpose applications in dry conditions. Furniture and interior fitments


Load-bearing applications in dry conditions


Load-bearing applications in humid conditions


Heavy-duty load-bearing applications in dry or humid conditions

Technical specifications for these grades are set out in the European standard EN 300 and in OSB manufacturers’ users manuals. For details, ask your national standards organisation, trade association, or timber supplier.
