The world’s largest air-supported, single-chamber membrane cushion has been installed by Vehovar & Jauslin and formTL engineers at a bus station in Aarau, Switzerland.
Nicknamed the ‘cloud’, the structure encompasses over 1000 sq m, made up of a steel frame and an air-supported membrane cushion made of synthetic material ETFE.
The construction process involved pressing high-pressure air into an airtight envelope to create the lightest possible structure.
A free form steel frame holds up the cloud from within, while a network of steel cables across the outer surface gives it structure.
Ventilation to the bus station is achieved by adjusting the air pressure in the inflated roof to suit the changing weather conditions.
