Claim:
A ceiling panel comprising a base having an upper face and a lower face, and a facing material secured across the lower face of the base, said base and facing material being rectangular in shape, the facing material functioning to provide the visible appearance side of the panel when the panel is suspended on a ceiling grid, the base having a stepped perimeter profile along two opposing perimeter edge regions, each edge region having a horizontal support kerf generally vertically midway in the edge region and a positioning kerf below the support kerf, the positioning kerf extending horizontally deeper than the support kerf and having an upper surface and a lower surface, the support kerf providing a suspension surface for the panel capable of being supported on a flange of a grid tee and assisting in horizontally positioning the panel on the grid flange, the positioning kerf allowing lift and shift installation and/or removal of the panel from the grid, the height of the positioning kerf being greater than the thickness of the facing material to provide for sufficient clearance for the installation and removal of the panel, the facing material being secured to the lower face of the base and being cantilevered beyond each of outermost edges of four sides of the base, whereby the facing material forms the lower surface of the positioning kerf.
