How to specify

Selecting the right louvre
involves these steps.

To select the right performance louvre for your project design:
1) The mechanical engineer defines the required volume flow rate (m ³/s) for mechanical plant or passive ventilation dictated by the mechanical equipment behind the louvres.
2) Mechanical engineer defines the maximum allowable pressure drop across a louvre before fan performance suffers.
3) The architect and engineer then balance the louvre façade area (m2) against the pressure drop requirements, required rain resistance, and aesthetics to get a mutually workable outcome.
4) Finally you can then specify the louvre that works for your design aesthetically and achieves the performance classification required for both aerodynamics and rain defence using the Australian Standard AS4740:2000 classification system.
Please note: louvre performance is proportional to the design airflow. For example, the higher the air velocity, the lower the rain defence.
