Engineered to provide excellent protection from rain penetration and good airflow, our Rain Defence Louvres are available in a choice of blade configurations, can be hidden behind attractive perforated screens or feature different blade depths to integrate beautifully with your building.
They are ideal when you:
- Need reliable resistance to wind-driven rain
- Can’t use a large plenum behind louvres due to cost or space considerations
- Plan to house sensitive equipment adjacent to the louvre system
- Must integrate the louvres into the building’s total design or house them behind architectural features or continuous line louvres

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.
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.
