HangAir

HangAir is part of the DUOL Group, built on more than 30 years of engineering expertise in air-supported structures and over 2000 installations worldwide. HangAir and DUOL structures use advanced membrane technology, but rely on different structural principles to achieve stability and structural strength. HangAir Structures are based on inflated load-bearing arches act as the roof structure, similar to conventional framed buildings, creating a large open space inside with flexible access and no internal overpressure. DUOL Air Domes are membrane structures where entire structure is stabilized by continuous internal overpressure. The interior remains under air pressure, with special doors and entry systems to preserve the overpressure.
