Suspended ceilings are secondary ceilings suspended from the structural floor slab above, creating a void between the underside of the floor slab and the top of the suspended ceiling. The gap between a suspended ceiling and the structural floor slab above is often between 3 to 8 inches which is why they are often referred to as dropped ceilings or false ceilings.
Suspended ceilings are very popular in commercial properties as they provide a useful space for concealing unsightly wires and installations that otherwise would alter the interior appearance of the building.
The space gained through installed a suspended ceiling has proved useful for distribution of heating, ventilation and air conditioning (HVAC) services and plumbing and wiring services, as well as providing a platform for the installation of speakers, light fittings, wireless antenna, CCTV, fire and smoke detectors, motion detectors, sprinklers and so on.
