OSB Boards

OSB (stands for Oriented Strand Board - a plate of ribbon oriented flakes) is a wood-based material made by compressing with the us of temperature, wood particles in the form of thin strands with adhesive. The usually used binder is  melamine-urea-formaldehyde, phenol-formaldehyde or isocyanate resin. OSB board has a layered structure: outer layers are made of fiber elements run parallel to the plate length (major axis) and the strands in the inner layer are arranged transversely to the length of the plate (parallel to the lateral axis). All layers are made up of elements of approximately same size


Besides veneering with phenol foil ( slab formwork with a smooth surface) and corrugated surface (anit-skidding board with imprinted net) there is no particular way of finishing the broad surfaced OSB boards, the manufacturers offer boards with narrow profiled surfaces to connect the groove and tongue.


The average density of OSB 650 kg / m3

Types of OSB

The PN-EN 300 distinguished the following types of OSB:

OSB / 1 - general purpose boards and boards used in interior (including furniture) for use in dry conditions.

OSB / 2 - support plates for use in dry conditions.

OSB / 3 - load-bearing boards for use in humid conditions.

OSB / 4 - boards with increased load-carrying capacity for use in humid conditions.

In addition, some manufacturers have in their offer panels with improved performance in terms of reaction to the fire.
