Suspended Ceilings 

Often used in office refurbishment and design, suspended ceilings are usually a secondary ceiling hung below the main ceiling and is very commonly used to conceal typical and essential construction items such as piping, wiring and ductwork. These may also be referred to as dropped ceilings, false ceilings and T-bar ceilings.

A common construction of a suspended ceiling is a grid work of metal channels in the shape of an upside down “T” (hence the other name described above), suspended on wire from the overhead structure. Channels are snapped together on a regularly space pattern. Then each partition is filled with lightweight tiles that fill or drop into the grid. The tiles can be made of many different materials including plastic, wood and metal. Light fixtures or air grilles (such as air conditioning units) can also fill the grids which is a common theme to most modern offices.

This type of ceiling came about to conceal the underside of the floor above and help with acoustic balance and control for a room. This developed over the years to help improve acoustic performance with enhanced sound absorption techniques.
