Quick Summary

A pneumatic structure, also known as an air-supported structure, is a type of membrane architecture stabilized by compressed air. Internal air pressure, slightly above normal atmospheric levels, maintains the structure's shape and stability. Entrances require air locks to prevent air loss.1

These structures are cost-effective for creating very long, column-free spaces, making them suitable for applications like exhibition halls, temporary warehouses, and swimming pool covers. Walter Bird first developed air-supported membranes in the late 1940s.12
