Louver, also spelled Louvre, arrangement of parallel, horizontal blades, slats, laths, slips of glass, wood, or other material designed to regulate airflow or light penetration. Louvers are often used in windows or doors in order to allow air or light in while keeping sunshine or moisture out. Louver systems are installed on most buildings to ensure a smoother intake and exhaust of air, and also to provide stronger resistance against rain and noise intrusion.
Louvers can be utilized in a range of performance types, including drainable, non-drainable, wind-driven rain resistant, combination, thin-line, acoustically rated, adjustable, and even extreme-weather resistant. When buying a louver system, make sure you have a clear understanding of the purpose of louvers and how louvers work so you can be sure that you are purchasing the right louver design for your needs.
