Pre-cast Glass Fiber Reinforced Gypsum (GFRG) components are a great choice for intricate architectural detailing, ranging from column covers and capitals to barrel vaulted ceilings. They are cast in a controlled environment prior to being sent to the jobsite and are easily replicated to produce multiple identical pieces. Installation methods for GFRG domes vary depending upon the location and the ceiling construction, but our installers are expert in many quality-tested methods. In suspended ceilings, GFRG ceiling domes may be suspended from hanger wire similar to a suspended ceiling. In wood or metal-framed ceilings, the GFRG dome can be attached to the framing with screws that are then countersunk and filled over.
