OSB 3

Definition

OSB stands for “Oriented Strand Board” and is made from thin veneer strands that are bonded together with a synthetic resin. Consisting of three cross-oriented layers the surface of the board is formed from strands oriented along the length of the board and the core strands arranged in cross orientation. This crosswise orientation of the individual layers achieves a high level of dimensional stability and an excellent mechanical performance. OSB is mildly bendable, can be compressed and is a very strong and durable waterproof material.

OSB is mostly made out of pine and is very easy to cut and work with. It can be varnished, painted or glued. Its smooth and even surface does not have any knots and natural wood surface finish can provide a very attractive appearance to the material.

OSB can be ordered in many thicknesses and panel sizes to fit different needs.

Field of application

OSB is mainly used in construction, building houses, in the walls of buildings, as a roof material and under floors. Since the material is very resistant it can also be used for making boxes to carry heavy items.
