Performance louvers, also known as air louvers or ventilation louvers, are architectural elements designed to provide airflow while maintaining privacy, security, or aesthetic appeal. These louvers are commonly installed in building facades, doors, windows, and mechanical equipment enclosures. They can be designed to allow airflow while preventing the entry of rain, debris, insects, or unauthorized individuals. By promoting natural ventilation, performance louvers can help improve indoor air quality and reduce the need for mechanical ventilation systems, thus saving energy and operational costs.
