Roof of factory described is thin, steel membrane constructed with insulation and roofing flat on ground and fastened to concrete anchor ring; it is then raised and stretched into dome shape by air pressure from ordinary ventilating blowers, and thereafter is supported by pressure of one ounce per sq. in. from these blowers; effect of pressure on occupants is negligible; working area is completely free of columns and other structural obstructions.
