OSB 4 TOP Straight Edge

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 higher 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).

Emissions 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.
