Single-hung windows are made of two panels, or sashes, but only one of those panels is operable. For ventilation, these windows can be lifted from the bottom while the top sash stays stationary. A single-hung and a double-hung window differ in the operation of the sash. Only the lower sash slides up and down with a single-hung shutter while both sashes are operable with a double-hung window.
