Plafon Gypsum
BUILDING MATERIALS & CONSTRUCTIONbeginner
Definition
Gypsum ceiling board or plasterboard — sheets of gypsum core with paper facings, attached to a suspended metal frame (rangka-hollow) to create a finished ceiling. Plafon gypsum is the standard dropped ceiling material in Indonesian commercial and residential interiors, offering acoustic absorption, easy installation of MEP (mechanical, electrical, plumbing) above, and a clean, flat finish.
Example
An Indonesian apartment interior uses 9 mm plafon gypsum suspended 30 cm below the concrete slab on a rangka-hollow frame — the 600×600 mm panels creating a modular grid that accommodates downlights, air returns, and sprinkler heads.
