Below are the FAQ's about EGGER OSB including the intended usage and features or the product.
OSB is an engineered plane and rigid wood panel made of wood strands of selected quality with controlled cross orientation, bound with a synthetic resin under high temperature and pressure conditions.
Depending on their technical class (type) and intended use, the boards can be used in dry or humid condition.
According to EN 300, there are 4 types of OSB, known as technical classes:
OSB/1 → general purpose non load-bearing boards for use in dry conditions (service class 1)
OSB/2 → load-bearing boards for use in dry conditions (service class 1)
OSB/3 → load-bearing boards for use in humid conditions (service classes 1 & 2)
OSB/4 → heavy-duty load-bearing boards for use in humid conditions (service classes 1 & 2)
Among these, OSB/3 is currently the most used product in Europe.
The standard OSB boards have un-sanded faces and sharp edges, but smooth/sanded faces and milled edges (2 or 4-sides „tongue and groove“ T&G profiles) are also possible to manufacture.
OSB is a plane and sturdy board, with remarkable mechanical properties and dimensional stability.
Its main function is the structural use (structural floor, roof and wall sheathing), but also incorporates the function of a vapor barrier and of an airtight layer when used in the exterior components of wood frame houses.
