Flaps open and press on all sides directly on to the inside of the frame when the window is locked. The window can no longer be levered.
Pushing the glass pane out is no longer possible due to the patented glazing technology. The glass pane is glued into the window frame all around and therefore keeps safely and securely.
Solid and elegant, but discreetly made silver designer closing elements together with the mushroom shaped peg in the window frame lock the window.
The Secustik handle with safe scanning protects against drilling from the outside (standard with UPVC and UPVC/aluminium window KF 500).
Concealed hardware ensures that the window cannot be levered at its hinges and additionally serves for discreet appearance and easy cleaning.
Closing sensors notify inconspicuously and reliably if and which windows or window doors are open or locked (can be combined with alarm systems).
Lockable handles offer optimum child security and perfect burglary protection in one handle. The window is locked via key or push button and cannot be opened, neither from the outside, nor from the inside.
Laminated security glass does not break apart. Tear-resistant foils hold the pane together, the glass stays tightly in the window frame and danger of injury is averted.
