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 Calculators
We've built 2 tools to help you with your specification process. One to help you calculate pressure drop for your chosen CS Louvre model, the other to help you calculate the area of louvre required for your project.
KEY FEATURES
- Blade orientation: Horizontal
- Joint options:
- Horizontal: visible or invisible
- Vertical: visible (interlocking mullion) or invisible (hidden mullion)
- Louvre depth: 154 mm (visible mullions)/ min. 231 mm (hidden mullions)
- Blade pitch: 146 mm
- Weight: 14 kg/m2, based on a 2 m x 2 m module size
- Maximum module dimensions (based on 1.5 kPa wind load):
- Max width: 3600 mm*
- Max height: 3600 mm*
* Maximum unit weight: 150 kg, including accessories. Site access and lifting capability should be assessed prior to specification and installation.

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.
