A louver system is a type of window covering that consists of horizontal slats or panels that are angled to allow light and air to pass through, while still providing privacy and protection from the elements. Louver systems are often used in residential and commercial buildings, as well as in outdoor applications such as patio covers and sunrooms. The slats can be adjusted to control the amount of light and air that passes through, and they can also be used to block out unwanted noise. Louver systems are available in a variety of materials, including wood, aluminum, and vinyl, and they can be custom-made to fit any window size or shape. They are also easy to install and maintain, making them a popular choice for many homeowners.
