OSB is a building and finishing material that made of thin chips located parallel to the plane of the sheet in layers with perpendicular direction of the chips, bonded with various waxes and resins. OSB is divided into classes according to water resistance:

​

• OSB-1 - intended for use in conditions of decreased humidity (furniture, upholstery, packaging)

• OSB-2 - used in manufacture of entire structures in dry area.

• OSB-3 - used in manufacture of entire structures with high humidity conditions.

• OSB-4 - used in production of constructions that carry significant mechanical weight in high humidity conditions.
