The OSB name, which was produced for the first time in Canada 14 years ago and is still being produced in almost every European country today, stands for ORIENTED STRAND BOARD. OSB is an acronym for it and the material is called in all countries under this name.
At first sight, OSB WOODEN PANEL looks like a product obtained through gluing the pieces of wood or coarsely chopped wood shavings with each other, and thus it may be thought as a material unsuitable to use reliably. Nevertheless, OSB Wooden Panels do not have such a simple structure. Production of OSBs consists of blending the thick pieces of wood with wood shavings. Dry wood shavings and pieces are scattered in thin layers and pressed in presses through gluing with special adhesives. OSB must not be confused with fiberboards or waterboards, because these two products are completely different.
The wood shavings have been regulated in OSB. It is arranged through scattering the wood shavings and chips parallel to each other in a layer format (in panel shape) within the panel from end to end, and then, diverting (?) each layer with the others, and obtained given that the last layer and the first layer are in the same direction. In a sense, this structure is similar to plywood production.
OSB wooden panels are alternative and economical materials thanks to their high performance in heavily humid working environment and easy-to-useness. It gives new opportunities in constructing the wooden modular buildings. Its availability in various thicknesses, the smoothness of its surface makes the material advantageous in terms of paintability, finishability, and varnishability.
In terms of resistance/durability, OSB has the same feature with the massive wood resistance. For instance, resistance features of 20mm-thick pinewood and 11mm-thick OSB panel are the same.
OSB that has found a widespread usage in our country for the last 5 years, and especially after the Gölcük Earthquake 1999, is used as carrier floor and ground in prefabricated houses, roofs, and in walls, partitions and roofs of Canadian/American villa type houses, and in mezzanines and/or the similar areas in all kinds of buildings.

STORING THE OSB WOODEN PANELS
• Wooden products must be protected from getting wet in the course of transportation, and stored in spaces closed, dry, and well ventilated.
• Palettes must be stowed under direct sunlight, covered with a covering, and the wedges below palettes must be tight enough.
• Storing in too dry and hot environments for long periods must be avoided; as keeping it bare under the sun or extremely hot conditions for a long time alters the humidity percentage in the ingredients of the product, surface stretching and spalling and thus bending and surface anomalies may occur.
POINTS OF CARE IN USE AND FITTING OF OSB WOODEN PANELS • It is recommended to have the panels wait for 3 to 8 days to adapt to the humidity of the place they are before fitting or the surface applications.
• When using on the exteriors, care must be taken to lap the joints of the panels with the support; it will be more appropriate to protect vertical joints by materials such as strip sheet iron, etc.
• Supports can be vertical or horizontal. It is not recommended that panels thinner than l0 mm be used with supports thick 50 to 60 cm. Panels in appropriate thicknesses must be used in the relevant spaces.
• Joints must not follow each other; it must be floored diverted (?) like the stonewall bond.
• In rich and open space floorings, due to deviations of the panel stemming from changes in humidity, a space not less than 10mm must be left at the borders of the floor according to length and width of the room, and also, approximately 1-mm-space on width direction and 3-mm-space on length direction must be left among the panels.
• It is recommended to use galvanized or rustproof screws to fix the floors in damp regions. Screw length must not be less than 2.5 times of the panel thickness; it will be more appropriate to use washered screws.
• In open space floorings, once the fixing process has been completed, it is recommended to keep the floor under protection until a protective cover is put to avoid from humidity-dependent changes. It is not proper to expose any wooden material to extreme heat or extreme rain directly.
