DISCHARGE
Classifications based on testing to EN 13030.
Features & Advantages
- The horizontal inverted blades of the front louvre create a continuous architectural line across the façade while providing visual screening of the rear module in elevated installations
- A high-performance vertical blade louvre module is positioned at the rear to provide excellent protection against wind-driven rain ingress
- Rear modules are powder-coated black as standard, to minimise their visual impact
- Tested to EN 13030 and AMCA-certified for proven airflow and rain defence performance
- AMCA 550 listed for proven resistance to high-velocity wind-driven rain
- Modules are factory pre-assembled and supplied as double-bank units for ease of installation
- Where only parts of the façade are functionally active, blanking
panels are used in place of blades within the rear louvre frame in non-active zones, helping to reduce costs - Sightproof design

Specification
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.
