Double-Hung Window

Definition: A window with two movable sashes that slide vertically. Opening the upper or lower sash allows ventilation within the same window frame.

Example

A homeowner lowers the top sash and raises the bottom sash to circulate air.

Keep the distinction clear

A single-hung window normally has only one movable sash. A double-hung window's balance mechanism can vary; it does not have to use a particular type of spring.
