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.


With ceiling-high door panels, as well as organically curved and inclined glass units, Sky-Frame is the key to individual spatial concepts and extraordinary architecture. True to the Bauhaus vision of “free-flowing space”, the sliding doors open up the living area with a flush transition. This allows inside and outside to merge seamlessly into one another. Thanks to the timeless frameless door design, the view is elevated to a fascinating design element.The Sky-Frame technology is 100% Swiss-made and stands for precise engineering and the pursuit of the best possible window.
