A retractable flexible screen is attached to a retractable barrier assembly fitted into a bottom edge portion of a window sash portion of a window unit. The retractable barrier assembly is provided with a weather seal and a moisture draining means. A weather strip is provided along a bottom edge of the screen. The screen is maintained in a retracted position within the retractable barrier assembly until it is desired to employ the screen. To deploy the screen, it is extracted from the retractable barrier assembly and a bottom edge is anchored against a sill portion of the window unit, thereby causing the screen to be automatically extended each time the sash is raised.
