Our panoramic windows combine long-standing expertise from the areas of metal windows, glass and facade construction.
The aim of Krapf was to develop an easily slideable, completely sealable glass window system in a glass facade, fitting flush to floors and ceilings, which will provide the highest degree of comfort and meet the highest building and aesthetic standards.
air-lux has used its many years of experience in facade construction, and its experience with metal windows, to develop an innovative large surfacearea glazing system that can be fitted into the overall aesthetic characteristics of a building, without sills.
air-lux is an innovation of the facade construction company Krapf AG (Ltd./LLC) Switzerland and is planned, manufactured and installed by the company itself. To date, 300 properties in Switzerland and abroad have been successfully fitted with the system.
