Abstract
An exterior door incorporates at least one moving glass insert or sash slidable in first and second spaced apart tracks. An end of the insert is coupled to an end of a spring biased rolled screen. As the insert moves from the roll, the screen is extracted therefrom providing a continuously variable length of exposed screen that exerts a retracting force on the insert. The insert may be supported at any one of a variety of positions by frictional forces exerted on the insert, or by the frictional and retracting forces, without need for counterbalances or latches.
