Energy efficiency, including daylight efficacy and thermal insulating qualities.Many manufacturers of modern dropped ceilings include sustainability as an objective. Indoor environmental quality includes ventilation, VOC emissions, lighting and thermal system control, thermal comfort, use of daylight for natural illumination, acoustics, and optimization of outdoor view availability. Environmental factors Indoor environmental quality This is sometimes achieved by adding insulation known as Sound Attenuation Batts (SABs), more commonly referred to as "sound batts", above the panels to help deaden sounds and keep adjacent rooms quieter. The acoustic performance of suspended ceilings has improved dramatically over the years, with enhanced sound absorption and attenuation. A noisy room can overstimulate occupants, while a too quiet interior may seem dull and uninviting. Custom runs of specialty ceiling tiles can be done at relatively low cost compared with the past.Īcoustic balance and control was another early objective of dropped ceilings. Further, drop out ceilings can also conceal the sprinkler systems while still providing full fire suppression functionality.įor many years, dropped ceilings were made of basic white tiles, but modern innovations now offer a plethora of options in sizes, colors, materials (including retro designs and faux leather, wood, or metal), visual effects and shapes, patterns, and textures as well as support systems and ways to access the plenum. Drop ceilings may also be used to hide problems, such as structural damage. Modern dropped ceilings were initially created to hide the building infrastructure, including piping, wiring, and/or ductwork, by creating a plenum space above the dropped ceiling, while allowing access for repairs and inspections. Supporting Electric Lighting Fixture from Suspended Ceiling FrameworkĮffective building design requires balancing multiple objectives: aesthetics, acoustics, environmental factors, and integration with the building's infrastructure-not to mention cost of construction as well as long-term operation costs. Wong founded Cepco Manufacturing, a company later absorbed into Ceilume, a division of Empire West, Inc. dropped ceiling patents to September 8, 1958įirst fully developed grid system conceptįirst integration of tiles and grid. Brown has sometimes been credited as being the inventor of the dropped ceiling even though other patents preceded his as shown in the table below. Patent Number US 2,984,946 A was granted on May 23, 1961. This invention provided suspended ceiling construction in which access may readily be obtained at any desired location. Brown of Westlake, Ohio, filed for a patent for Accessible Suspended Ceiling Construction. This process could be time-consuming and expensive. Once the repair or inspection was completed, the tiles had to be reinstalled. Initially modern dropped ceilings were built using interlocking tiles and the only way to provide access for repair or inspection of the area above the tiles was by starting at the edge of the ceiling, or at a designated "key tile", and then removing contiguous tiles one at a time until the desired place of access was reached. Hall on May 28, 1919, and granted on October 16, 1923. 1,470,728 for modern dropped ceilings was applied for by E. Blackfriars Theatre in London, England, built in 1596, had dropped ceilings to aid acoustics. These could be made with simple planks, or coffered. It may also be referred to as a drop ceiling, T-bar ceiling, false ceiling, suspended ceiling, grid ceiling, drop in ceiling, drop out ceiling, or ceiling tiles and is a staple of modern construction and architecture in both residential and commercial applications.ĭropped ceilings and ceiling tiles were used in Japan for aesthetic reasons as early as the Muromachi Period (1337 to 1573). Secondary ceiling hung below a main ceilingĭropped ceiling featuring ceiling tiles, lights, air diffusers, smoke detector, and more Dropped ceiling with ceiling tile light fixtureĪ dropped ceiling is a secondary ceiling, hung below the main (structural) ceiling.
