Ceiling panel for suspended ceilings

1. A suspended ceiling, comprising:

a plurality of ceiling panels,

a suspended ceiling gridwork comprising a plurality of main beam members connected to a plurality of cross members to form a uniform and regularly spaced pattern of cells wherein each cell is filled with a ceiling panel;

the ceiling panel comprising:

a layer of foam insulation;

a first facing sheet positioned on a lower major face of the layer of foam insulation, the first facing sheet formed from a scrimmed metallic material;

a second facing sheet positioned on an upper major face of the layer of foam insulation, the second facing sheet having a major surface that is exposed to a space of a facility and formed from a scrimmed metallic material;

a surface covering layer formed from a material selected from the group consisting of mineral fibers, fiberglass or fiberglass-based composites, ceramic-based materials, plaster, polymers or combinations thereof, wherein the surface covering layer is bonded on an exposed face of the first facing sheet, the surface covering layer having a major surface that is exposed to an active space of the facility,

wherein the foam insulation layer, first facing sheet, second facing sheet and surface covering layer are co-extensive with each other, and each of the layers having a planar orientation and an uninterrupted form extending from a first major edge to an opposing second major edge and extending from a first minor edge to an opposing second minor edge.

2. The suspended ceiling of claim 1 , wherein the layer of foam insulation is formed from rigid, closed-cell, phenolic-based materials.

3. The suspended ceiling of claim 2 , wherein the rigid, closed-cell, phenolic-based material has zero Ozone Depletion Potential (ODP).

4. The suspended ceiling of claim 1 , wherein the first facing sheet material is bonded to the layer of foam insulation with a polyurethane adhesive system.

5. The suspended ceiling of claim 1 , wherein the first facing sheet material is formed from a scrimmed aluminum foil material.

6. The suspended ceiling of claim 5 , wherein the scrimmed aluminum foil material has a thickness of 0.001 inches.

7. The suspended ceiling of claim 5 , wherein the scrimmed aluminum foil material is reinforced with a layer of glass scrim.

8. The suspended ceiling of claim 1 , wherein the second facing sheet material is bonded to the layer of foam insulation with a polyurethane adhesive system.

9. The suspended ceiling of claim 1 , wherein the second facing sheet material is formed from a scrimmed aluminum foil material.

10. The suspended ceiling of claim 9 , wherein the scrimmed aluminum foil material has a thickness of 1 mil.

11. The suspended ceiling of claim 9 , wherein the scrimmed aluminum foil material is reinforced with a layer of glass scrim.

12. The suspended ceiling of claim 1 , wherein the surface covering layer further includes a fire-retardant coating configured to provide desired fire-retardant properties.

13. The suspended ceiling of claim 1 , wherein the surface covering layer further includes a sound deadening coating configured to absorb sound.

14. The suspended ceiling of claim 1 , wherein the surface covering layer has a thickness in a range of from about 20.0 microns to about 2000.0 microns.

15. The suspended ceiling of claim 1 , wherein the main beam members has a cross-sectional shape of an inverted “T” forming opposing legs extending radially from a central member.

16. The suspended ceiling of claim 1 , wherein the ceiling panel has opposing first and second major edges and opposing first and second minor edges, and wherein the first and second major and minor edges have a tegular edge profile.

17. The suspended ceiling of claim 16 , wherein the first and second major and minor edges have a concealed “T” edge profile.
