Window hardware

Perimeter hardware is the heart of the window: it delivers a tight seal, micro-ventilation and resistance to forced entry. Choose the package that fits your needs.

9 solutions that increase comfort and security

Available functions and systems

Concealed Designo hinges

Concealed Designo hinges

Invisible hinges mounted in the profile — the sash opens up to 100° without visible hinges from outside. Elegant, minimalist facade appearance. Sets new standards in window aesthetics.

Anti-burglary hardware RC1–RC2

Anti-burglary hardware RC1–RC2

Standard: 1 mushroom-head locking pin. Security: all mushrooms. RC1: 4 mushroom pins + steel plate (3 min resistance). RC2: 8 mushroom pins + steel plate (5 min resistance) — compliant with standard DIN EN 1627.

Magnetic alarm contact

Magnetic alarm contact

Magnetic opening sensor integrated into the window frame — monitors the position of the sash. In case of break-in attempts or glass breakage, sends a signal to the alarm system. Discreet installation in the profile.

Tilt First system

Tilt First system

Child safety — a 90° turn of the handle results in tilt mode (cannot be opened inwards). Full opening only after pressing the lock button, out of the child's reach.

Misoperation lock

Misoperation lock

A safeguard that prevents the window from being closed in tilt mode. Prevents damage to the hardware and frame from the sash slamming when the handle is in the wrong position due to wind.

Brake in the handle

Brake in the handle

Mechanism slows the rotation of the handle — the sash does not slam suddenly after turning the handle. Prevents the sash from hitting the frame and prolongs the life of the hardware.

Comfort hardware

Comfort hardware

Handle mounted lower than standard — facilitates window operation for wheelchair users, seniors and for windows above standard height. Meets accessibility requirements.

Multi-stage tilt

Multi-stage tilt

Possibility to lock the sash in several tilt stages — e.g. 5°, 10°, 15°. Ideal for ventilation without the risk of the window being prised open by wind or rain.

Micro-ventilation

Micro-ventilation

Handle turned 45° upwards — the sash remains closed, but air flows through the profile gaps. Ventilation without tilt opening — useful at night and in bad weather.
