Tested and certified

The louvres’ insertion loss is tested and certified in accordance with ISO 7235:2003 (in accordance with the Peutz report A 1659-1).

The airborne soundproofing has been tested and certified in accordance with ISO 140-3:1995 (in accordance with the Peutz report A 1659-1).


Different dimensions of acoustic louvres have recently been subjected to extensive testing. As a result we can optimally combine the desired volumetric flow rate (pressure loss) with the desired noise requirement. This allows us to consistently produce the optimal acoustic louvre for you.

Acoustic louvres for industry

Ventilation for technical rooms, installations and machines

Louvres for construction industry

The acoustic louvres are suitable for utility buildings and housing.

Ventilation for machines and installations

Louvres as an acoustic wall or as part of a total solution.


Standard louvres

We supply four types of louvres, which means the acoustic louvres are relatively standardised. This offers a high degree of efficiency. In terms of dimensions the louvres are produced on a project-specific basis.

Customised acoustic louvres

We can always provide a suitable solution for specific problems. We developed specific acoustic louvres for a project requiring a large number of louvres to comply with the exact project requirements. Our knowledge of sound enables us to successfully carry out such complex projects.

Calculate your acoustic louvres

You can use the louvre selection tool to quickly and easily calculate the acoustic and technical air properties of acoustic louvres.
