That's air-lux

air-lux is a floor-to-ceiling glass façade system with large-surface sliding windows and a unique sealing concept.

The maintenance-free air-lux sliding window system with sliding windows up to 18 m2 was developed by Krapf AG, a leading Swiss metal and façade engineering company and comprehensive provider of quality solutions. With air-lux, Krapf AG offers architects, façade planners and home-builders a versatile window façade system that is as architecturally and aesthetically appealing as it is structurally sound.

Functionality and quality

air-lux is planned and produced in-house and installed by our own teams. Since the first installation in 2004, over 4'500 sliding windows have been installed. And that experience shows: air-lux impresses with the highest functionality and quality, is the leading provider in terms of sliding window size and achieves top marks for impermeability and safety.

Impermeability, safety and robustness

With their patented pneumatic sealing system, air-lux sliding windows achieve the best impermeability in the industry. The craftsmanship of the robust, refined aluminium frames meets the highest quality standards. air-lux can be adapted to individual safety requirements up to RC3.

Flexible opening technologies

Sliding windows and fixed glazing can be employed with varying arrangements, elements and opening types.
