air-lux sliding windows

Large dimensions,
excellent characteristics

In 2004, Krapf AG developed air-lux – a glass façade system that sits flush with the floor and ceiling, with large, frameless sliding windows and a unique sealing method. Since then, over 4,500 air-lux sliding windows have been fitted worldwide.

With air-lux, Krapf AG offers architects, façade planners and building owners a versatile window façade system that is as architecturally and aesthetically appealing as it is structurally sound. air-lux installations are planned in our own workshops in Engelburg, produced with premium aluminium profiles and materials, and installed by our own fitters.

Flexibility and design freedom

Whether for private houses, business premises or skyscrapers, with different configurations, special opening options and innovative special solutions, air-lux offers the flexibility to make the individual ideas and wishes of architects and builders a reality.
