The 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.
Our OSB 4 TOP 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. Besides others, this layer structure is one of the reasons for the exceptional mechanical strength properties of the EGGER OSB 4 TOP.
