False, or suspended, ceilings systems consist of prefabricated removable tiles placed in, or attached to, a grid of metal strips called tees. These tees rest in "L" shaped wall molding and are suspended by metal wires attached to steel beams, concrete supports and other
preexisting structural materials. One benefit of false ceilings over other systems is that they conceal electrical wiring, duct work, pipes and other unsightly components that are left exposed during building construction, providing an attractive veneer and easy above-ceiling access in case repairs or modifications are necessary. A study done by CISCA (Ceilings & Interior Systems Construction Association) stated that additional benefits of suspended ceiling spaces include the use of less energy and a greater reduction of ambient noise than other ceiling systems.
Exposed Grid False Ceilings
Exposed grid false ceilings are suspended ceiling systems that use three types of metal grid (11 foot long main tees, shorter 4 foot long tees and smaller 2 foot long tees) in a grid pattern that is visible from below. These sections of exposed grid come in 15/16-inch grid width and a thinner 9/16-inch grid width. The choice between the two types comes down to the consumer's personal preference. Tees are available in hundreds of matte or gloss finish colors to help them coordinate with office decor styles.
Concealed Grid False Ceilings
Concealed grid false ceilings are suspended ceiling systems that use three types of metal grid (11 foot long main tees, shorter 4 foot long tees and smaller 2 foot long tees) in a grid pattern, which the ceiling surface is attached to. Because the grid doesn’t break up the ceiling surface, wood, plaster and other continuous-coverage designer ceiling surfaces that are not an option with visible grid systems can be used. This system doesn’t allow easy above-ceiling access.
Drywall and Short-Spanning Drywall False Ceilings
Drywall false ceilings are metal grid systems specifically designed to support the considerable weight of drywall panels, which other grid systems are not designed to carry. This grid system is generally preferred over traditional hat and channel stud systems because it is engineered to clip together, eliminating the need for screws, pop rivets, crimpers (used to attach tees to wall molding), and other tools generally used to install ceiling systems.
A short-spanning drywall false ceiling is the same type of system as above, except it uses smaller sections of metal grid that that are designed for narrower office spaces. Since this system also uses fewer materials than traditional metal stud systems, it is easier to install, saving more overall time, labor and money.
False Ceiling Tiles and Panels
Ceiling tiles and surface materials include metal, plaster, wood, aluminum, PVC, mineral fiberboard, Gypsum Board and a selection of custom-colored designer tiles are available for exposed and concealed grid styles. Many of these tiles are fire and termite resistant and heat and sound insulating, making their use preferable over other ceiling systems.
