Acoustic louvres for your project
Alara-Lukagro’s acoustic louvres are suitable for diverse applications; in construction, industry, on maritime vessels and offshore. Each market has specific requirements and guidelines, with which we align the louvres; examples include materials, certified filling and required airflow etc.
Sound insulation values louvres
Alara-Lukagro acoustic louvres, type AL-R, offer a solution where there are noise-reducing requirements for an outside air grille.

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