Board materials OSB
Technique
OSB (Oriented strand board) - It is manufactured in wide mats from cross-oriented layers of thin, rectangular wooden strips compressed and bonded together with wax and resin adhesives (95% wood, 5% wax and resin). The layers are created by shredding the wood into strips, which are sifted and then oriented on a belt or wire cauls. The mat is made in a forming line, the layers are built up with the external layers aligned in the panel's strength axis with internal layers cross-oriented.
Dimensions (mm)
Sheet: 2500x1250; 2500x625
Thickness: 6; 8; 9; 10; 11; 12; 15; 18; 22
Types
Depending on what edges are produced there are OSB sheets with smooth edges, TG2 – sheets with tongue on 2 longer edges, TG4 – sheets with tongue on all 4 edges.
Depending on thickness, wax, resin adhesives and processing of boards there are OSB sheets for use in dry (OSB1, OSB2) or wet environment (OSB3, OSB4).
Application
OSB is used as sheeting in walls, floors and roofs, also for producing of packing, palettes, furniture etc. - almost everywhere where smooth and solid surface is needed.
