Where continuous blade appearance is desired and high level of rain defence needs to be maintained, double bank arrangements offer a solution.
- A fronting ventilation louvre, in a choice of 75mm or 100mm blade pitch, offers a continuous blade appearance across a façade
- One of our rain defence models with vertical blade arrangement is located at the rear to provide excellent protection from wind driven rain ingress
- Where only parts of the façade are functionally active, blanking panels are used behind ventilation louvres in non-active areas, keeping costs down
- All double bank configurations shown have been tested for airflow performance

Specification
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.
