KF 500 combines innovate design with technical know-how. The window sash is not visible from the outside through its glass appearance and can not be distinguished optically from fixed glazing. This sash also conceals the revolutionary I-tec locking which renders levering of the window impossible, unrivalled in the industry. Integrated flaps press on to the inside of the frame on all sides when locking and therefore offer maximum burglary protection. Additionally, KF 500 can be equipped with I-tec ventilation, a ventilation system integrated into the window frame.
