OSB is made from precisely cut wood strands that are oriented in predetermined directions and a synthetic resin binder; these are pressed between heated platens to form a structural panel.

OSB is most commonly manufactured with three distinct layers. In the surface layers the strands are generally oriented in the long direction of the panel, and in the core layer the strands may be oriented across the panel.

This gives OSB different properties in the two panel directions, in a similar manner to plywood. Plywood is available in a range of grades, we stock OSB/2 which ia a load-bearing board for use in dry conditions.

From stock it is available in the following sizes:

2440 x 1220mm in three thicknesses from 8mm to 18mm.
