FlexScreen is perfectly suited for the very common tilt-and-turn windows. The window remains fully operable without having to remove the insect screen.   FlexScreen can also be used on a double-sash window, but only on the sash that opens first. The second sash can only be opened after removing the FlexScreen.<br \/>\nIn addition, you must check the transition to the second sash.
