Where maximum airflow is the primary consideration, our ventilation range is a perfect solution. Our louvres offer high levels of airflow with low pressure drop, whilst still delivering some weather protection. Continuous line or modular mullion options can be specified to fit with desired facade design.
They are ideal when you:
- Need a high free area / high airflow solution
- Need an economical louvre
- Don’t mind occasional rain water entry
- Require a continuous line appearance on the facade

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.
