ABSTRACT:
An air inflated bubble roof, such as for a stadium, arena or the like, includes a compression ring extending around the perimeter of the roof. An upper and a lower cable net each spans and is attached to the compression ring. An inflatable membrane member is located between the two cable nets and bows the cable nets apart when it is inflated. A bladder is located within the inflatable membrane member and, in combination with the upper and lower parts of the membrane member, forms a seal around its perimeter.
