Oriented Strand Board (OSB)

OSB varies in color from a light straw color to a medium brown depending on wood species used, resin system adopted and pressing conditions employed. It contains no knotholes, core voids or points of weakness. 

Overview

OSB is an engineered wood-based panel consisting of strands of wood which are bonded together with a synthetic resin, the strands are pressed together in layers. In the outer layers strands are generally oriented longitudinally in line with the panel length, whereas in the middle layers strands generally lie in a cross wide direction.

Working Properties

The main merits of OSB lie in the field of its mechanical performance, which is directly related to the geometry of the strands and their orientation within the panel. Although OSB is made up of relatively large strands of wood, its surface is relatively smooth and this can be further enhanced by sanding without losing the aesthetic character which is unique to OSB.

Main Uses

Due to its high mechanical properties it's widely used for flooring, roof decking and wall sheathing, but there is also a wide field of other applications where OSB as a wood-based panel product can be utilised.
