Kind of polywood
Depending on the conditions of use we distinguish:
OSB2 - for indoor applications
OSB3 - for indoor and outdoor use (in an environment with moderate humidity), the most popular material used in construction,
OSB4 - board with higher mechanical resistance and high moisture resistance, dedicated to the most demanding applications
Depending on the edges shape, OSB is available in two varieties: with straight edges and milled for tongue and groove.
