Inflatable or tensile membrane roof [RFA1]

An inflatable roof uses fabric chambers pressurised with air to form a self-supporting structure.

A tensile membrane roof is made of stretched fabric, usually stretched in two directions to form a tensioned surface. Examples of tension membranes include polyester coated with PVC and glass fibre coated with Teflon.
