OSB is the abbreviation of Oriented Strand Board (boards made from oriented particles). OSB is a multi-layer panel made from long, slim particles of pre-determined shape and thickness, the so-called “strands”. In the outer layers, the stands are generally oriented along the length of the panel, whereas they are oriented across its width in the core layer. Although OSB is manufactured from relatively large particles, its surfaces are comparatively smooth, which can be further enhanced by sanding.
For the production of OSB, freshly-harvested timber is used, mainly composed of softwoods (Norway spruce, Scots pine), but also of hardwoods.
Due to its good mechanical characteristics, OSB is specially suitable for load-bearing construction. Typical applications are wall sheathing and roof sarking in timber constructions.
Different qualities of OSB are available for diverse fields of application.
