Panel shutters are window coverings made from solid panels that can be opened or closed to control light and privacy. They are typically mounted on the interior or exterior of windows and can be made from various materials, including wood, vinyl, or composite materials. These shutters can be customized in size and style to fit different window shapes and home designs. They provide insulation and can help reduce energy costs by keeping heat in during winter and blocking sunlight in summer. Panel shutters are often used in conjunction with other window treatments, such as drapes or blinds.
