The terms “louvers” and “dampers” are often used interchangeably, but they are actually two different types of devices. Louvers are panels with angled slats that are used to control the amount of air and light that enters a space. They are typically used in windows, doors, and walls to provide ventilation and privacy. Dampers, on the other hand, are used to regulate the flow of air in ducts, vents, and other air systems. They are usually made of metal and are designed to open and close to control the amount of air that passes through. Both louvers and dampers are important components of any building’s HVAC system, as they help to regulate the temperature and air quality of the space. Louvers and dampers can also be used to reduce noise levels, as they help to muffle sound waves and keep them from entering the space.
