Claim:
1. A ceiling system comprising: a longitudinally extending grid support member including a bottom surface; a first and second ceiling panel mounted below the grid support member, each ceiling panel including an acoustic panel body having a top surface, opposing bottom surface defining a horizontal plane, plurality of peripheral edges extending therebetween defining a perimeter, a central region of the bottom surface spaced inwards from the peripheral edges, and an annular peripheral region of the bottom surface surrounding the central region and lying between the central region and the peripheral edges; a longitudinally-extending joint formed between adjoining first peripheral edges of each of the first and second ceiling panels; a first facing sheet adhered to the central region of the first ceiling panel with a factory-applied adhesive layer, and an annular perimeter portion of the first facing sheet being un-adhered to the peripheral region of the first ceiling panel adjacent to the joint; wherein the perimeter portion of the first facing sheet adjacent to the joint extends laterally outwards beyond the first peripheral edge of the first ceiling panel forming a first cantilevered flap, and the perimeter portion of the first facing sheet opposite the joint extends to but does not extend beyond a second peripheral edge of the first ceiling panel opposite the first peripheral edge; wherein the first cantilevered flap of the first facing sheet extends across the joint to the second panel such that the cantilevered flap is positioned on the peripheral region of the second ceiling panel.
