Oriented Strand Board (OSB) is a product made from thin strands stacked on each other in oriented layers connected by a synthetic resin. OSB boards are currently the most widespread wood-based material for a variety of building-structural applications. Boards do not contain natural solid wood defects (knots, cracks, etc.). Strands size in the surface layer makes apparent natural structure, colour and rustic appearance of natural wood, and brings new possibilities to interior design. OSB is principally manufactured from quality coniferous wood. Thin strands are gently dried, and a synthetic resin with a fixed proportion of paraffin emulsion is applied. Board bonding is processed under high temperatures and pressures. Excellent mechanical properties are achieved by selecting: suitable wood, defined shape of wood strands, and the particular crosswise orientation stacking of the three individual layers. Dimension, shape, and orientation of strands in individual layers make maximum use of the natural wood properties to achieve the best structural-physical boards’ parameters. The strands in OSB surface layers are oriented in the longitudinal direction and in the base layer the strands are oriented across the panel. These two directions of strand orientation in each layer give the board a higher level of dimensional stability and excellent mechanical efficiency. At the same time boards show several times greater strength along the longitudinal axis (major axis) than the crosswise direction (minor axis). Correct panel orientation towards support is important, especially during installation. This is the main difference when comparing OSB to particleboards and wood fibreboards which are weaker but have similar strength in all directions.OSB boards are the most modern type of large area material on the wooden basis which is available at present. Development and production of OSB boards takes place in accordance with the current trends of healthy housing focused on envir
