Abstract
In the design of the interior finishing of the ceiling of Sundome Fukui, teflon-coated glass-fiber fabric was used as the membrane ceiling. This material allowed us to design the free form of the ceiling appropriate to a lot of purpose, and showed its excellency in acoustics and workability in construction, The form of the ceiling of the dome reflects the form of the reverse side of the roof. The new membrane ceiling method made possible to construct such complicated form. This method proved its high quality equal and smooth finishing, and sufficient property of acoustics of the dome.
