The largest stadium with an air-supported roof is the 80,311 capacity Pontiac Silverdome Stadium in Detroit, Michigan, USA. The 4 ha (10 acre) translucent fabric roof that covers the 235 m (770 ft) x 183 m (600 ft) octagonal stadium is held up by pressurised air provided by 25 large fans. Made of teflon-coated fibreglass, the roof is 62 m (202 ft) high. Although the scientific principles behind the roof are the same as those that operate to keep a balloon inflated, the air pressure in Dome causes no discomfort and is within the limits of natural atmospheric pressure variations. The stadium is equipped with revolving doors to ensure that the air doesn't leak out as people enter.
The structural engineers were Geiger-Berger Associates of New York City, USA. Exact air pressure is said to be 5 lb/ft².
The largest standard-size airhall is 262m 860ft long, 42.6m 140ft wide and 19.8m 65ft high, first sited at Lima, Ohio, USA and made by Irvin Industries of Stamford, Connecticut, USA.
