Window systems for aluminium
The new ALU XT hardware system
The entirely novel ALU XT hardware with its innovative operating rod technology is setting new standards in production. Irrespective of the window dimension it gets on with a maximum of five operating rods and makes it possible to easily insert additional locking points or accessories without machining the operating rod any further. The ALU XT is designed for fast production and stands for optimised production processes and a revolutionary easy installation with flexible assembly sequence as well as self-positioning components which reliably compensate for tolerances.
ALU 90° opening restrictor
The new ALU 90° opening restrictor protects the sash and hinge side against improper use and damage: it limits the turn-opening width of the sash to 90°, thus preventing it from bumping against the reveal or against furnishings. To achieve this, the sash is attenuated before reaching the 90° position and then effortlessly moved to the end position. The locked end position prevents unwanted shutting in the event of a draught. The innovative solution is not only durable and easy to use, but it is also extremely robust, as confirmed by successful testing in accordance with DOEB guidelines. Simple to install and requiring zero maintenance, the new ALU opening restrictor is suitable for use with both surface-mounted and concealed hinge sides now also in turn-only and turn and tilt aluminium windows.

Under the slogan "NEXT LEVEL" we'll be showing you at FENSTERBAU FRONTALE 2026 new dimensions of 360° room comfort, how ideas emerge from visions and sustainable solutions emerge from ideas, which fascinate. Central control for intelligently controlling and networking smart solutions involving the building shell will be the particular focus of the trade show presence. Further developed from future scenario to real-world application, it creates via Matter and KNX too healthy, safe and comfortable spaces where people feel at ease. What's more, you'll be in store for portfolio expansions for the TITAN and KFV product groups, the new GRP thresholds for the PORTAL HS and many other innovations with added value for fabricators and end users. On top of that, the ALU XT – the new game-changing hardware generation for aluminium windows – an absolute first at the fair stand, will also be a must-see.
