Abstract
The invention is directed to a ceiling which is supported within a closure structure such as a dome. The edge of the ceiling is sealed to the closure structure by a non-permeable flexible fabric. Both the ceiling and the edge seal are airtight to prevent the passage of gases from a region below the ceiling within the closure structure to a region above the ceiling within the closure structure.
