Weather louvres, also known as rain or weatherproof louvres, are designed to protect ventilation and air conditioning systems from rain, wind-driven debris, animals and direct sunlight while still ensuring proper airflow. Commonly installed on building facades, ventilation systems, air intake openings, or mechanical equipment enclosures, these louvres are suitable for exhaust and low to medium velocity intake applications. Their design minimizes pressure drop and maximizes free area for efficient operation.
