A standard ventilation louvre will provide the maximum airflow required with minimal rain defence.
These louvres tend to be preferred for projects where economy is the primary consideration, high free area is important and occasional water penetration will not cause significant problems.
When specifying a standard ventilation louvre we recommend looking at the blade spacing and the free area provided by the louvre.
