EGGER OSB 4 TOP installation board with tongue and groove profile

Advantages of the OSB 4 TOP installation board in use:

• Due to the stable and precisely fitting tongue and groove profile, the OSB 4 TOP installation boards can be installed quickly and easily.

• Due to their high bending strength and rigidity, our OSB 4 TOP are always a safe option for the production of durable, load-bearing  roof formwork and subfloors, even with large spans.

• For the OSB 4 TOP, we provide the tested calculation values for the static verification even for a board thickness of 30 mm with the declaration of performance.

• In contrast to OSB 3, our OSB 4 TOP has a lower thickness swelling during moisture absorption and improved dimensional stability. This leads to greater safety during transport, during the construction period and in the building.

• Due to their high rigidity, the OSB 4 TOP installation boards are also ideally suited for floating installation .

• EGGER OSB 4 TOP installation panels are produced in the thickness range of 12 to 25 mm with a guaranteed characteristic bulk density of more than 620 kg/m3. This means that they have a reduced burn rate and advantages in the fire protection verification .

OSB 4 TOP boards are available as installation boards with a 4-sided tongue and groove profile in different sizes, thicknesses, formats and thicknesses – simply choose the board that offers the required load capacity. For further information, please refer to our current  product range.

Emission class

For production, mainly fresh coniferous wood, only a formaldehyde-free glue system and paraffin wax are used. As a result, all limit values currently applicable to wood-based panels with regard to formaldehyde release are significantly undercut.

Our OSB 4 TOP is glued 100% formaldehyde-free, which corresponds to formaldehyde emissions like those of untreated wood.
