The double-hung window is the most common window type. It consists of “top and bottom” upper and lower sashes that slide vertically over each other in separate grooves in the side jambs. Each sash is provided with springs, balances or weatherstripping to hold it in place in any location.
The window sash may be divided into a number of lights by small wood cross-members called muntins. The choice of multiple lights or open pane is often dictated by the size of a home and the style of the home’s architecture.
Hardware for double-hung windows includes the sash lifts that are fastened to the bottom rail, although they are sometimes replaced by a finger groove in the rail. Other hardware consists of sash locks or fasteners located at the meeting rail. They not only lock the window but also draw the sash together to provide a tight fit.
