Suitable for applications where both noise control and airflow are required, our Acoustic Louvres can be installed as standalone screens, or can be integrated into building façades. They can also be used in combination with any of our rain defence or ventilation models, if required.
These Louvres are suitable for the following types of projects:
- Car parks, plant rooms, substations, cooling towers and any other application that requires both sound attenuation and ventilation
- Areas where sound levels that escape from exterior or interior walls need to be minimised
