Vertical blinds are window coverings made up of vertically hanging slats or vanes. These slats, constructed from materials such as fabric, vinyl, or aluminum, are suspended from a top track and can be maneuvered to regulate the amount of light and privacy. Vertical blinds are available in various materials and styles, allowing you to select options that match your decor and preferences. They are versatile, working well for windows of different sizes, including sliding glass doors.
