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
