A window consisting of an upper sash and a lower sash that slide vertically. The sashes may be divided into panes.
Double-hung windows have two sashes which, when both are closed, are positioned one immediately above the other. Both sashes can be slid up and down in tracks, but are kept from dropping to the sill by counterweights attached by cords or chains and concealed in the window casing. By the nature of their design, double-hung windows can be opened to a maximum of 50% of the area of the window opening. Double-hung windows have been the most common American residential window design since the 18th century.
Two operable sash slides open vertically. The sash weight is offset by a counterbalancing mechanism mounted in the window.
