Abstract

A ceiling system in one embodiment includes an overhead support grid comprised of a plurality of intersecting grid support members and a ceiling tile mountable to the grid. Retaining clips support the ceiling tile from the grid which may be concealed from view. The retaining clips each include a cavity that receives a grid support member and a pair of resilient mounting elements configured to lockingly engage a support member. The mounting elements are laterally movable in response to inserting the support member into the cavity of the retaining clip. In one embodiment, the movable elements include locking tabs which create a snap-fit interlock with the grid support member for securing the ceiling tile to the grid.

Claims

1. A factory-fabricated ceiling panel comprising:

a panel body comprising a top surface, a bottom surface, a first panel edge extending continuously in a vertical direction between the top and bottom surfaces, and a second panel edge extending continuously between the top and bottom surfaces, the first panel edge being opposite the second panel edge; and

a facing sheet coupled to the panel body by a factory-applied adhesive, the facing sheet being continuous and comprising a first flap having a portion that protrudes beyond the first panel edge and a second flap having a portion adjacent the second panel edge and overlying the bottom surface that is not adhered to the panel body.

2. 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.

3. The ceiling panel of claim 1, wherein the facing sheet comprises laminated non-woven glass fibers.

4. The ceiling panel of claim 1, wherein the second flap protrudes beyond the second panel edge.

5. The ceiling panel of claim 4, 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.

6. 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.

7. The ceiling panel of claim 6, wherein the facing sheet comprises a fourth flap having a portion that protrudes beyond the fourth panel edge.

8. A factory-fabricated ceiling panel comprising:

a panel body comprising a top surface, a bottom surface, a first panel edge extending continuously in a vertical direction between the top and bottom surfaces of the panel body, the bottom surface of the panel body having a first surface area; and

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;

the factory-applied adhesive located on a region of the bottom surface of the panel body having a third surface area, whereby the third surface area is less than the first surface area.

9. The ceiling panel of claim 8, wherein the region is inset from the first panel edge of the panel body.

10. The ceiling panel of claim 8, 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 8, wherein the facing sheet comprises laminated non-woven glass fibers.

12. The ceiling panel of claim 8, wherein the panel body further comprises a second panel edge extending between the top and bottom surfaces, the region being inset from the second panel edge.

13. The ceiling panel of claim 12, wherein the second panel edge is opposite the first panel edge.

14. A factory-fabricated ceiling panel comprising:

a panel body comprising sound-absorbing material selected from the group consisting of mineral fiber board, fiberglass, jute fiber, wood, and composites, the panel body having a top surface opposite a bottom surface and a plurality of panel edges extending between the top and bottom surfaces of the panel body;

a facing sheet comprising laminated non-woven glass fibers, the facing sheet having a top surface opposite a bottom surface, and a plurality of sheet edges extending between the top and bottom surfaces of the facing sheet; and

the facing sheet coupled to the panel body such that the facing sheet protrudes beyond at least a first one of the panel edges, the facing sheet including a portion that is;

(i) adjacent the first one of the panel edges,

(ii) overlying the bottom surface of the panel body, and

(iii) not adhered to the panel body.

15. The ceiling panel of claim 14, wherein the sound-absorbing material is mineral fiber board.

16. The ceiling panel of claim 14, 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.

17. The ceiling panel of claim 16, 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.
