Suspended Ceilings


USA: Suspended Ceilings: Drop Ceiling Manufacturers





Suspended Ceilings, sometimes known as drop ceilings or dropped ceilings, are second ceilings installed below the main ceiling. They hide wiring, piping, and ductwork, into a void which is known as the plenum. An array of metal extrusions is hung on wires from the main ceiling. Ceiling panels or tiles rest on the grid. Light fittings or air vents may also be fitted into the grid. In addition to hiding pipework and cabling, suspended ceilings can be used to provide acoustic absorbency, and to provide better heat insulation. 


The leading manufacturers, described below, have comprehensive websites, with information on all aspects, including online catalogs, colours and materials, and care and maintenance.
