An integrated window screen system including a roller screen assembly which provides for out of view storage of the screen material (22). The screen material (22) is attached to the sash (10) of a double hung or similar window. The opposite edge of the screen (22) is attached to a roller drum (30) mounted on a shaft (78). The drum (30) is mechanically interconnected to a spring motor (26) which includes a constant force spring (62) which has the effect of keeping the screen (22) taut when deployed. The roller drum (30) is located below the window sill (50).
