Thanks to its first-class properties, EGGER OSB 4 TOP is the ideal panel for timber construction – whether in roofs
. The OSB 4 TOP offers reliable and durable real timber construction quality:
• 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)

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.
