Abstract: A fenestration unit and screening assembly are provided. The fenestration unit may be a window assembly for supporting a variety of windows such as a single-hung, a double hung or a bi-pass window. The window assembly may include a window screen assembly either manufactured with the window or as an after-market product. The screen assembly may include a spring-loaded screen roller for winding and unwinding a screen about the roller. The upper and lower windows may pivot into a residence when opened a certain amount. The windows may pivot about the same axis that the screen roller rotates, which minimizes the change in position and tension of the screen while the windows are tilted. A seal may be provided to seal space between windows when the windows are in any position. Also, a screen engaging member may be provided to inhibit undesirable unwinding of the screen from the roller.
