A ceiling system comprises a pair of spaced overhead longitudinal grid support members and a light-weight ceiling panel suspended therefrom. The panel may be an acoustical honeycomb panel in one embodiment. Localized elongated reinforced areas or sections are formed on the top facing which support a plurality of hangers mounted on each section. The reinforced sections coincide in arrangement with the layout of the support members and structurally strengthen the top facing in select areas. In one embodiment, each reinforced section may comprise a stiffening spline attached to the top facing. The ceiling panel is hung from the grid support members via the hangers and reinforced sections. Fasteners may be used to attach the hangers to the reinforced sections which resist pullout when the panel is hung. In certain embodiments, the reinforced sections extend longitudinally through a central portion of the panel to prevent sagging between the panel sides.

An acoustic panel (for absorbing sound) includes a first sheet with spaced microperforations, a second sheet with microperforations more widely spaced than the microperforations of the first sheet, and a first cellular core sandwiched between the first sheet and the second sheet. The panel can be spaced from a surface, such as a wall. A second cellular core can be provided between the second sheet and a third sheet. The third sheet is preferably solid without microperforations but can have microperforations. Noise Reduction Coefficient (NRC) can be 0.8.

A prefabricated ceiling panel and method of forming the same is provided. The panel comprises various built-in features including cable trays, lighting elements, and other features. The panel further comprises a layered structure comprising a plurality of layers to increase the fire resistance, insulation, and/or structural features of the panel.

A building panel for a wall or ceiling is provided. The panel comprises a first plate forming a front of the panel, a second plate forming a rear of the panel, and a core structure positioned between the first plate and the second plate and being adhesively bonded to the first plate and the second plate. The panel further comprises an attachment member for attaching the panel to a wall or ceiling or to a structure attached to a wall or ceiling, and a mechanical fastening device which extends between and mechanically fastens the first plate to the second plate and/or the attachment member.

A ceiling system includes a ceiling support structure supporting a plurality of ceiling panels, each ceiling panel including a core layer having a top surface facing a first interior space above the ceiling panels, a bottom surface facing a second interior space below the ceiling panels, and a plurality of peripheral edges extending between the top and bottom surfaces. A top frame layer extends from the top surface and a thermal layer is on the top frame layer opposite the top surface. The thermal layer has a first surface facing away from the top frame layer and a second surface facing toward the top frame layer. The top frame layer supports the second surface in a spaced-apart manner from the top surface to form one or more air gaps between the top surface and the second surface. The first and second surfaces have a thermal emissivity of 0.5 or less.
