Classifications based on testing to EN 13030.
Features & Advantages
- Wide blade pitch maximises airflow performance
- Channels in blades and vertical sections help collect and drain away rain water
- Visible mullions to align with other façade elements; an invisible vertical joint detail can be achieved with hidden mullions for a continuous appearance on the façade
- Tested to EN 13030 and AMCA-certified for proven performance
- Supplied to site as pre-fabricated modules for efficient installation

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.
