Fully integrated, secure, comfortable

Ambitious window design for stylish architecture does not stop at the design of the window profile. Our windows are designed such that no hinges are visible. With I-tec Secure for UPVC and UPVC/aluminium windows, we have developed the principle — visible technology only where absolutely necessary — to also include the window frame. Instead of protruding locking pins, integrated flaps ensure the safe locking of the sash. The locking flaps are connected invisibly in the hollow chambers of the sash profile. This ingenious construction enables 30% lower view heights. Generous window sizes and energy-saving triple glazing require heavy sash versions. The window is held by a four-joint hinge at the bottom and a stay-arm hinge at the top. The new design of bearing parts allows sash weights of up to 130 kg in compact design.

In the standard model, windows with I-tec Secure already comply with resistance class RC2N without a lockable handle (with lockable handle and burglary-resistant glass RC2) according to EN 1627-1630 — burglary protection tested as standard.
