Inflatables came very much into the public eye as architectural and domestic objects when synthetic materials became commonplace. Iconic structures like the US Pavilion at the 1970 Osaka Expo by Davis and Brody and Victor Lundy's travelling pavilion for the Atomic Energy Commission popularized the idea that inflatables can be a way to build large structures with very extendend interior spans without pillars. These great hopes for inflatable structures would later be dashed by the many practical difficulties faced by inflatable buildings, such as climatization, safety, sensitivity to wind and fireproofing that, currently, restrict their use to very specific circumstances.
