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.

First claim

What is claimed is:

1. A ceiling panel comprising:
a panel body comprising a top surface, a bottom surface that terminates at a first panel edge, the first panel edge being planar and extending between the top and bottom surfaces of the panel body, the bottom surface of the panel body being planar and having a first surface area; and
a facing sheet coupled to the panel body, the facing sheet comprising a top surface, a bottom surface, the bottom surface of the facing sheet having a second surface area;
an adhesive region that bonds a portion of the bottom surface of the panel body to the bottom surface of the facing sheet, the adhesive region having a third surface area;
wherein the third surface area is less than the first surface area.

2. The ceiling panel according to claim 1 , wherein the third surface area is less than the second surface area.

3. The ceiling panel according to claim 1 , wherein the first surface area is less than the second surface area.

4. 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.

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

6. The ceiling panel of claim 1 , the adhesive region comprising an adhesive composition.

7. The ceiling panel of claim 6 , further comprising a peripheral region that circumscribes the adhesive region, the peripheral region being substantially free of the adhesive composition.

8. The ceiling panel of claim 7 , wherein the peripheral region has a fourth surface area, wherein the summation of the third surface area and the fourth surface area are substantially equal to the first surface area.

9. The ceiling panel of claim 8 , wherein the facing sheet is unadhered to the panel body in the peripheral region.
