Features & Advantages
- Wide blade pitch to maximise airflow performance
- Channels in blades and vertical sections help to collect and drain away rain water
- Visible mullions to line up with other façade elements; invisible vertical joint detail can be achieved with hidden mullions for continuous look
- Delivered to site as pre-fabricated modules for efficient installation
Applications
- Where high free area / high airflow solution is required
- Where economy is primary consideration
- In exhaust areas where low pressure drop is needed, such as data centres
KEY FEATURES
- Blade Orientation: Horizontal
- Mullion Type: Horizontal: Visible, Vertical: Visible (interlocking mullion) or Invisible (hidden mullion)
- Louvre Depth: 154 mm – visible mullions, 231 mm hidden mullions
- Blade Pitch: 146mm
- Weight: 14kg/m2 based on a 2m x 2m module size

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.
