OSB 4 TOP Straight Edge
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.

What makes the OSB 4 TOP from EGGER so special
Thanks to its first-class properties, EGGER OSB 4 TOP is the ideal panel for timber construction – whether in roofs, walls, ceilings or floors. The OSB 4 TOP offers reliable and durable real timber construction quality:
• stiffening,
• secure vapour barrier
• airtight level due to guaranteed minimum air permeability of ≤ 0.12 m³/(m²h) even for the highest requirements.

An overview of the advantages in application:
- Available formats of up to 3.30m length allow ceiling height constructions and enable an economical and cut-optimized wall planking.
- The EGGER OSB 4 TOP offers a hugher moisture resistance compared to OSB 3 which results in an improved dimensional stability. This leads to more safety on the construction site and in the building.
- EGGER OSB 4 TOP with straight edges are produced in the thickness range from 12 to 25 mm with a guaranteed raw density of at least 620 kg/m3. As a result, they have a reduced burn-up rate and offer advantages in fire protection certification.
- It goes without saying that we guarantee all properties through the comprehensive and meaningful CE declaration of performance (DoP) .
OSB 4 TOP is available in different thicknesses
The OSB 4 TOP is available in a wide range of formats and thicknesses. Please refer to our current delivery programme for information.
Emission classes
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.
