I-tec locking renders levering of windows impossible. This patent is unrivalled in the window brand and is already integrated in UPVC or UPVC-aluminium window KF 500. Integrated flaps press on to the inside of the frame from all sides when locking and therefore offer maximum burglary protection.
- Security class RC2 already as standard
- Locking elements are almost completely integrated in the frame; this makes for easy cleaning
- Low viewing height of UPVC and UPVC-aluminium window KF 500 ensures more light
