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

Specification Calculators
We've built 2 tools to help you with your specification process. One to help you calculate pressure drop for your chosen CS Louvre model, the other to help you calculate the area of louvre required for your project.

Specification
Guidance
The principal reason for using louvres is to allow the movement of air. But, louvre specification is a balance between form and function, with louvred façade appearance playing an important part in the selection process.
