A bay window, also referred to as bow windows, consists of several angled panels that protrude outward from a wall of a home to form an alcove that provides a wide peripheral view. Typically, the angled window panels of a bay window are either casement, single, or double-hung windows so they can be opened to provide ventilation. In contrast, the main window will be a picture window that provides an unobstructed view. Below the bay window sill, within the alcove, a bench can be placed to provide a seating area.
