About: Inflatable building

An inflatable building is a structure constructed using two layers of membrane connected together, typically using spars made from the same material. The cavity formed between the layers is pressurized with air producing a rigid structural element which allows large span structures to be achieved. The key difference between air-supported buildings and inflatable buildings is that air-supported buildings require airlocks at all the access points to prevent air being lost when doors are opened since the entire occupied space of the building is pressurized. Inflatable buildings like this commonly serve sports, such as tennis and indoor golf.
