1. A retractable screen system for a fenestration assembly including a sash slidably engaged with a frame of the fenestration assembly, the system comprising:
a catch assembly configured to couple to an outer surface of the sash, the catch assembly comprising a catch element;
a pair of edge rails, each edge rail of the pair of edge rails forming a rail slot and configured to couple to opposite sides of the frame; and a screen assembly comprising:
a roller housing configured to couple to an outer surface of the frame;
a roller assembly disposed within the roller housing and substantially hidden from view;
a control bar configured to project beyond the sash and into each of the rail slots, the control bar comprising a hook element extending along at least a portion of the control bar, the hook element configured to selectively engage the catch element; and screen material coupled to the roller assembly, edges of the screen material projecting into each of the rail slots and an end of the screen material coupled to the control bar; the roller assembly configured to apply tension to the screen material to wind the screen material around the roller assembly and to permit the screen material to unwind from the roller assembly under a tension applied by moving the catch assembly away from the roller assembly when the hook element engages the catch element,
wherein the catch assembly is operable to rotate away from the control bar of the screen assembly when the sash is rotated out-of-plane, and
wherein the hook element is configured to automatically disengage from the catch element as the catch assembly is tilted.
