The principal objective of Ventilation (or Performance) Louvre systems is to allow the passage of air, whilst providing a measure of protection against the rain.

Specifying performance has not been helped by conflicting technical information given by louvre manufacturers which quotes percentage free areas measured in different ways, namely as resistance to airflow and aerodynamic coefficients alternatively.

Design considerations include:

1.Site location and exposure

2.Severity of local (site) weather conditions

3.Location and exposure of louvres on building

4.Airflow rate and direction through louvre

5.Maximum acceptable pressure drop

6.Degree and depth of water penetration acceptable

7.Special solutions for sloping applications

8.Single bank,Double bank,Triple bank for optional.

For a true comparison of performance, the aerodynamic coefficient and the degree of rain defence effectiveness are the only sensible measures ,Approved by BSRIA UK。
