Only KF 500 can offer such a range of technical know-how in one window. Next to I-tec glazing, the all-round gluing of the glass pane with the window frame, KF 500 is equipped with the unrivalled I-tec locking as standard. Integrated flaps press on to the inside of the frame from all sides when locking and thereby practically make levering of the window impossible. Upon request, KF 500 can also be equipped with I-tec ventilation, a ventilation system integrated into the frame. Each room will then be aired according to its Needs.
