False Ceiling

False ceiling (also suspended ceiling, dropped ceiling) is a secondary ceiling installed below the primary structural ceiling, providing space for utilities (HVAC ducts, electrical, lighting) and improving acoustics, aesthetics, and thermal control. Per NBC 2016 Part 8 + IS 5054:1968, false ceiling is standard in modern Indian commercial and residential construction. Major Indian false-ceiling suppliers: Saint-Gobain Gyproc, Armstrong, USG Boral, Knauf India.

Main false-ceiling systems: (1) Gypsum board (GI grid + gypsum board) — most common; smooth finish, paintable; ₹250-450/m². (2) Mineral fibre tile — ceiling tiles in metal grid; acoustic absorption; ₹350-650/m². (3) Metal — aluminium or steel pan; modern aesthetic; ₹500-1200/m². (4) PVC panel — economical, water-resistant; ₹200-400/m². (5) Wooden — premium aesthetic; ₹800-2000/m². Drop height (gap to primary ceiling): typically 200-450 mm for utilities; 500-800 mm for major MEP.

Applications: (1) Office buildings — most common application; integrated lighting and HVAC. (2) Residential apartments — premium finish in living and bedroom areas. (3) Hospitals — particularly with antimicrobial tiles. (4) Hotels and commercial — aesthetic and functional. (5) Auditoriums and theatres — acoustic-tuned ceilings. The most-overlooked aspect of Indian false-ceiling: maintenance access. Modern offices have utilities in the ceiling void requiring routine access; false-ceilings should have access panels at HVAC equipment, electrical junction boxes, and fire dampers — typically 600 × 600 mm minimum.
