A suspended ceiling system comprising:
- a plurality of inverted-T runners concealed within said system;
- kerfed edge ceiling tiles supported at said kerfed edges by said inverted-T runners, adjacent said tiles being in proximate contact along the lower edge surfaces thereof distal said inverted-T runners concealing said inverted-T runners from view below, wherein;
- at least one said ceiling tile in said system comprises a central portion coplanar with the remainder of said tile and optionally vertically demountable and separable from the remainder of said tile along a cut defining said central portion through said tile perpendicular to the upper and lower surfaces thereof, said cut having a width no greater than 0.020 inches and further defining upon optional removal of said central portion a central opening within said ceiling tile wherein said central portion is recessed upwardly of the lower surface of said tile.
A ceiling system comprising ceiling tiles comprising a peripheral portion and a central portion wherein the peripheral edge of said peripheral portion is provided with a kerf parallel the upper and the lower faces of said tile, said kerf being of depth sufficient to suspendedly receive during installation of said tile the edge of an inverted-T runner and to completely conceal said inverted-T runner from view below upon suspended juxtaposition of said tile with a next adjacent tile in ceiling assembly array, the central portion of said tile being optionally demountable before or after installation along a cut through said tile perpendicular to the planar surfaces and edge kerfing thereof, said perpendicular cut being of width no greater than 0.020 inches wherein said optionally vertically demountable central portion is recessed upwardly of the peripheral portion of said tile.
