Shutters are generally composed of a series of horizontal slats, or louvers, that can be adjusted to control the amount of light and air that enters a room, and to provide privacy and security. Shutters come in a variety of styles, including louvered, panel, and board and batten, among others. They can be customized to fit different window sizes and shapes, and can be painted or stained to match the exterior of the house or interior decor. Shutters are often considered a more traditional and elegant window covering option compared to other options such as blinds or shades.
