OSB boards

OSB (oriented strand board) are natural wood boards with increased strength indicators, stable dimensions, easy to process, with relatively good moisture resistance parameters and versatile application. OSB is a particularly popular material in construction – in floor, wall and roof constructions.

OSB is made from chipped chips of various shapes, thicknesses and lengths. Fresh, undried logs (mainly softwood) are used for boards Chips are dried, treated with binders, laid out in a certain structure and compressed at high temperature. Chips are arranged or oriented in three or five layers. In the upper layer of the plate, the chips are oriented in the direction of its length or width, and in the middle layer – perpendicular to the direction of the chips of the upper layer. Such an arrangement of chips creates an even distribution of the strength and hardness of the plate both in the longitudinal and transverse directions. OSB boards can be sanded – with a smooth surface and unsanded – with unevenness caused by chips.

Advantages of OSB Boards

• High strength
• No tears, cracks, splits or other defects
• Easily processed material – can be sawed, drilled, planed
• Relatively high moisture resistance (depending on the classification group)
• Environmentally friendly product
• Multiple possibilities of use

Classification of OSB Boards:

• OSB/1 – wide application in dry interiors, including furniture production.
• OSB/2 – for making load-bearing structures in dry interiors, for example partitions.
• OSB/3 – universal material with increased moisture resistance, can be used for both interior and exterior work. Suitable for black floors, mezzanine coverings, wall elements, roofing under certain roof coverings.
• OSB/4 – high load boards with good moisture resistance. Can be used for the construction of load-bearing structures, can be used in outdoor conditions and in places with increased humidity.
