Suspended ceilings are known under many names, including dropped ceilings, t-bar ceilings, false ceilings, grid ceilings, drop in and lay in ceilings. Regardless of what name you use, they function exactly the same way. A grid is suspended below the main structural ceiling which effectively conceals the old, original ceiling above and creates space to run cables, wires and ventilation systems. Suspended ceilings can be installed in almost any type of building. They are also able to used effectively to create smaller office or storage spaces within a large warehouse or factory.
