Our expertise: Private homes

Living with a view – just how you like it. Our goal is to enable the client and architects to make their visions a reality – without compromising on functionality. That’s why we set standards with air-lux in terms of function, security and flexibility – for maximum architectural freedom.

Whether the aim is clean and minimalist or striking and exclusive, air-lux gives to the builders and architects new design freedom to create groundbreaking architecture with glass façades.

air-lux can be individually matched to any property, integrating into the building envelope without a sill ? for frameless window façades of unique dimensions. Whether horizontal, diagonal or around-the-corner, the sliding panels and the opening and tilting options can be customised adapted to individual wishes and ideas. It is also easy to integrate standard windows, balcony and entrance doors, and tilt-and-turn windows into the air-lux system. This also applies to post and frame façades. Thanks to the consistent profiling, the combination of elements is visually imperceptible.

These three characteristics make air-lux the right choice for private homes

Guaranteed impermeability

The air-supported sealing system from air-lux guarantees outstanding structural values.

When closed, the perimeter ring seal ensures 100% impermeability against heavy rain, wind and noise. In contrast to systems with sealing lips or brushes, this invisible, nearly maintenance-free air-lux technology enables consistent performance of the air seal without signs of wear. The leads to very low maintenance costs and an improved ROI.

Absolute security

The robust air-lux basic construction can be upgraded up to resistance class RC3.

If required, additional components, multiple locking systems and laminated safety glass provide maximum burglary resistance up to resistance class RC3. Alarm glass or bullet-resistant glazing further increases security and burglar resistance (special bullet-resistant designs up to BR4-NS resistance class).

Electronic components for monitoring the locking position and locking the sliding door also enable the sliding window to be controlled and monitored via the building services (alarm system, building management system, etc.) – also via smartphone and tablet.

On request, our air-lux technical department, in collaboration with electrical planners and security will invisibly integrate these into the monitoring concept and building services.

Maximum operating and living comfort included

(1) The sliding windows are operated in the window frame using a button with integrated LED.
(2) The sliding windows are opened and closed smoothly ? either fully automatically or manually without any effort.
(3) For a threshold-free transition, the floor flap automatically raises and lowers again when the window is closed.

Of course, the functions can also be controlled through the building?s control systems or via smartphones and tablets. In exterior areas, entry options such as key switches, codes, fingerprints and badges are all possible. In the event of a power failure, the elements can be operated manually and close automatically.

On request, we can also handle the planning, preparation and installation of sun protection systems, slot ventilation and insect protection screens for optimal quality of life. For more privacy, darkening systems can be installed on the interior side.

Exclusive individuality in materials

In addition to the conventional surfaces made of anodised aluminium or powder coated, we offer a unique material fusion with aluminium in the core and fine wood in the interior and/or solid bronze in the exterior.

The interior large aluminium sliding windows can be customised with 16 types of wood. The feel, appearance and surface can be determined individually for wood, aluminium and bronze. The result: architecture with a unique character ? with all the technical and structural virtues of the air-lux base version in aluminium.
