These European Style Windows offer versatile design. But, with the ever-changing function, comes inconvenient hassles. Bare windows lead to lack of privacy, discomfort, restless sleep, flooding light–and so much more. Finally, Hunter Douglas has come up with the ideal window coverings for tilt turn windows. TrackGlide® is a revolutionary design in window covering operation. A simple track adheres to the very edge of the window frame–as close to the glass as possible, yet not on the glass. The continual adjustments of these windows are no longer an issue. Maintain privacy, comfort and control while enjoying your tilt turn windows.
