  •  Maximum Rain Defence Solutions

The main objective of Weather Louvres is to allow the passage of air, whilst providing the area beyond the room with protection from rain penetration. When specifying weather louvres we recommend comparing the airflow class and the level of rain defence provided by the louvre. Our CS RS-5605 weather louvre offers the best combination of airflow, rain defence and spatial efficiency of any product on the market.

  •  Maximum Airflow Solutions

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.

  •  Screening Solutions

Screening  louvres are generally used in locations where rain penetration is acceptable or the location is sheltered from adverse weather conditions as they generally offer a poor level of weather performance. Often used on the top of buildings to conceal HVAC systems, screening louvres help to hide unsightly equipment whilst providing passage of air to plant machinery. For optimal screening performance its worth remembering that screening louvres can be turned upside down to better screen plant machinery when viewed from below.
