With their patented pneumatic sealing system, air-lux sliding windows achieve the best impermeability in the industry. When closed, the perimeter ring seal ensures 100% impermeability – against driving rain, wind and noise. Air is generated in the frame and pumped inaudibly into the seal.

Material and robustness

Material and robustness

Air-lux 173 stands for exceptional Swiss manufacturing precision. The robust and high-quality aluminium design with its slim profile achieves top marks in testing up to a maximum size of 25 m2 (max. dimensions 8 x 3.1m). The patented sliding window system is maintenance-free. The surfaces are made of permanently weather-resistant anodised aluminium or powder-coated.



The highly resistant air-lux basic construction can be enhanced with additional mechanical and electronic components and specific glasses in tested designs that can be upgraded up to class RC3.
