Gypsum (GRG) Ceiling Domes

Gypsum Ceiling Domes, Moulding and More

Gypsum ceiling domes are recommended for ceiling domes larger than 7 feet in diameter. Anything smaller we would recommend FRP ceiling domes. Ceiling domes larger than 84 inches create difficulty installing and may also increase freight charges due to larger crating requirements. Therefore our gypsum or GRG ceiling domes are supplied in sections making it very simple to load into any room size for installation purposes.
