Our Egger OSB 4 TOP has many properties that go beyond the OSB 4 standard of EN 300. The very high load-bearing capacity and stiffness, as well as the high moisture resistance and dimensional stability, offer a high degree of safety in all construction applications.
They have a 3-layer structure of flat aligned strands (micro-veneers). The two cover layers are aligned parallel to each other, the middle layer is perpendicular to them. This layer structure is the reason for the good mechanical strength properties.
