Ceiling panel for suspended ceilings

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.
