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.
Emissionsclasses
The production mainly uses fresh coniferous wood,a formaldehyde-free bonding system and paraffin wax. As a result, the formaldehyde emissions are well below all the currently known limit values of wood-based panels.
Our OSB 4 TOP is 100% bonded without formaldehyde. The formaldehyde emissions of our OSB 4 TOP correspond to emission similar to untreated wood.
