Like some windows, ARCHED windows have a curved top and are often used to add an architectural element to a building. SHUTTERED windows have shutters that can be opened and closed, providing protection from the elements and added security. Curtained windows are covered with curtains or drapes, which can be opened and closed to provide privacy and light control. Tinted windows have a tint applied to them, which can reduce glare and heat from the sun. Paned windows are divided into multiple sections, usually with glass in each section. Ledged windows have a ledge at the bottom, which can be used to hold plants or other items. Drivethru windows are typically found at restaurants and banks, and allow customers to place orders or conduct transactions without leaving their vehicles.
