ENTRY
DISCHARGE
Classifications based on testing to EN 13030.
Features & Advantages
- Wide-pitched extruded blades for maximum airflow performance
- Designed to provide some protection against wind-driven rain at lower face velocities
- Choice of mullions to create a desired effect on the façade (visible or hidden)
- Tested to EN 13030 and AMCA-certified for proven performance
- Optional glazing frames allow easy installation into curtain walling or glazed façades
- For applications requiring blast-resistant performance, refer to model BL-4089
- 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.

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.
