ENTRY
DISCHARGE
- Chevron, double-bank design, for maximum sound attenuation.
- Mineral wool infill material with acoustic, thermal, and fire-resistant properties. Water-repellent to prevent moisture build-up, damp, and rot.
- Galvanised mesh on the underside of the louvre blades maximises noise reduction performance.
- Can be installed as standalone screens or integrated into building façades. They can also be used in combination with other louvre models if required.
- Sightproof design.
- Supplied as modules, for ease of installation.
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.

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.
