A louver is a window or door feature that is composed of a series of angled slats that are used to control airflow and light penetration. Louvers are commonly used in buildings to provide ventilation, shade, and privacy. They can be used to control the amount of light and air entering a space, while also allowing for a view of the outside. Louvers are available in a variety of materials, including wood, aluminum, and vinyl, and come in a range of sizes and shapes. Louvers can be used in both interior and exterior applications, and are often used in combination with other window treatments, such as curtains or blinds. Louvers are a great way to add style and functionality to any space, while providing the perfect balance of light, air, and privacy.
