A ceiling system includes a grid support member, and first and second ceiling panels abutted at a joint. In the factory-supplied condition, each panel has a facing sheet already adhesively bonded to a central region of the panel. Perimeter portions of the facing are left un-bonded to an annular peripheral region of the surface surrounding the central region. This allows seams to be made in the field. The facing sheet comprises a cantilevered flap extending beyond a peripheral edge of the panel. During field installation, the flap of a first panel extends across the joint overlapping the second panel's un-bonded facing sheet in the peripheral region. The double thickness of facings is cut to form a seam laterally offset from the joint, which is concealed. A field applied or activated adhesive bonds the facing to the peripheral regions of each panel. A related installation method is disclosed.

1. A factory-fabricated ceiling panel comprising: a panel body comprising a top surface, a bottom surface, a first panel edge extending between the top and bottom surfaces, and a second panel edge extending between the top and bottom surfaces, the first panel edge being opposite the second panel edge;a facing sheet coupled to the panel body by a factory-applied adhesive, the facing sheet comprising a first flap having a portion that protrudes beyond the first panel edge and a second flap having a coextensive portion overlying the bottom surface and adjacent the second panel edge that is not adhered to the panel body; andthe first flap terminates in a first sheet edge spaced a first distance from the first panel edge, the second flap terminates in a second sheet edge spaced inward from the second panel edge by a second distance, and the first distance is greater than the second distance. 2. The ceiling panel of claim 1, wherein the first flap further comprises a portion overlying the bottom surface and adjacent the first panel edge that is not adhered to the panel body. 3. The ceiling panel of claim 1, wherein the panel body comprises sound-absorbing material selected from the group consisting of mineral fiber board, fiberglass, jute fiber, wood, and composites. 4. The ceiling panel of claim 1, wherein the facing sheet comprises laminated non-woven glass fibers. 5. The ceiling panel of claim 1, wherein the panel body comprises a third panel edge extending between the top and bottom surfaces, and a fourth panel edge extending between the top and bottom surfaces, the third panel edge being opposite the fourth panel edge, the third and fourth panel edges intersecting the first and second panel edges, wherein the facing sheet comprising a third flap having a portion that protrudes beyond the third panel edge. 6. The ceiling panel of claim 5, wherein the facing sheet comprises a fourth flap having a portion that protrudes beyond the fourth panel edge. 7. A factory-fabricated ceiling panel comprising: a panel body comprising a top surface, a bottom surface having a panel center point, and a plurality of panel edges extending between the top and bottom surfaces of the panel body;a facing sheet comprising a bottom surface having a sheet center point, a top surface, and a plurality of sheet edges extending between the top and bottom surfaces of the facing sheet;a portion of the bottom surface of the panel body that is adjacent to one of the plurality of panel edges is not adhered to the facing sheet; andthe facing sheet is positioned and coupled to the panel body such that: (1) the panel center point and the sheet center point are offset from one another; and (2) the facing sheet protrudes beyond at least a first one of the panel edges. 8. The ceiling panel of claim 7, wherein the panel center point and the sheet center point are offset from one another by a distance that is parallel to the bottom surface of the panel body. 9. The ceiling panel of claim 7, wherein the panel center point is defined as a point that is equidistant from opposing panel edges on the bottom surface of the panel body, and the sheet center point is defined as a point that is equidistance from opposing sheet edges on the bottom surface of the facing sheet. 10. The ceiling panel of claim 7, wherein the panel body comprises sound-absorbing material selected from the group consisting of mineral fiber board, fiberglass, jute fiber, wood, and composites. 11. The ceiling panel of claim 7, wherein the facing sheet comprises laminated non-woven glass fibers. 12. The ceiling panel of claim 7, wherein the facing sheet is coupled to the panel body so that the facing sheet protrudes beyond the first one of the panel edges and a second one of the panel edges, the first and second ones of the panel edges being adjacent to one another. 13. The ceiling panel of claim 12, wherein the facing sheet is coupled to the panel body so that the facing sheet further protrudes beyond a third one of the panel edges, the first and third ones of the panel edges being opposite one another. 14. A factory-fabricated ceiling panel comprising: a panel body comprising a top surface, a bottom surface, a first panel edge extending between the top and bottom surfaces of the panel body, the bottom surface of the panel body having a first surface area;a facing sheet coupled to the panel body by a factory-applied adhesive, the facing sheet comprising a top surface, a bottom surface, and a first sheet edge extending between the top and bottom surfaces of the facing sheet, the bottom surface of the facing sheet having a second surface area; andthe panel body further comprises a second panel edge extending between the top and bottom surfaces of the panel body, the first panel edge being opposite the second panel edge, and the facing sheet comprises a second sheet edge opposite the first sheet edge, the second sheet edge having a coextensive portion overlying the bottom surface of the panel body and adjacent to the second panel edge that is not adhered to the panel body;wherein the second surface area is greater than the first surface area, and the first sheet edge protrudes beyond the first panel edge. 15. The ceiling panel of claim 14, wherein the panel body comprises sound-absorbing material selected from the group consisting of mineral fiber board, fiberglass, jute fiber, wood, and composites. 16. The ceiling panel of claim 14, wherein the facing sheet comprises laminated non-woven glass fibers.
