An acoustic insulated ceiling system is disclosed. The system comprises a first profile and a second profile. The system comprises a carrier layer connected to the first profile and the second profile. As such the carrier layer is suspended between the first profile and the second profile. The system comprises a bottom layer in a high density material. The bottom layer supports on the carrier layer. The bottom layer extends from the first profile to the second profile. The system comprises an intermediate layer in a low density insulation material. The intermediate layer supports on the bottom layer. The system comprises a top layer in a high density material. The top layer supports on the intermediate layer. The top layer extends from the first profile to the second profile.

A ceiling suspension system that includes a plurality of acoustic panels that are configured to be installed or attached into openings of a grid formed by main runners and cross runners of the ceiling suspension system. The acoustic panels include a plurality of main blades that extend in the same direction as the main runners and cross blades that extend in the same direction as the cross runners. Two or more of the main blades comprise a kerf in a first lateral edge of each main blade. The kerf comprises a first slot and a second slot that form a stepped configuration.

A carrier component for a ceiling system and/or a ceiling system that includes the carrier component. The carrier component may include a body portion that extends along a first longitudinal axis and a plurality of support members that extend from the body portion in a spaced apart manner. Each of the support members may extend along a second longitudinal axis. Each of the support members may include a distal end, first and second ledges located on opposite sides of the second longitudinal axis, and third and fourth ledges located on opposite sides of the second longitudinal axis, the first and second ledges being closer to the distal end of the support members than the third and fourth ledges. One or more ceiling panels may be coupled to the carrier component via engagement with the first and second ledges or the third and fourth ledges of the support members.

The present invention is directed to an acoustic ceiling panel having a first major exposed surface opposite a second major exposed surface, the acoustic ceiling panel comprising: a first layer having an upper surface opposite a lower surface, the first layer comprising: a first body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the first body being air-permeable; and a first attenuation coating applied to the first body; a second layer having an upper surface opposite a lower surface, the second layer comprising: a second body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the second body being air-permeable; and a second attenuation coating applied to the second body; and an adhesive present between the first and second layers.

The disclosure provides a ceiling tile including a curable coating composition including 10-50 vol. % inorganic binder, based on the total volume of solids in the dry coating composition, wherein the inorganic binder is an alkali metal silicate or an alkaline earth metal silicate and 50-90 vol. % inorganic filler, based on the total volume of solids in the coating composition, wherein the binder and the filler are not the same and the coating is substantially free of an organic polymeric binder. The ceiling tiles have a backing side and an opposing facing side, and a cured coating layer disposed on the backing side of the panel, the backing side being directed to a plenum above the fibrous panel in a suspended ceiling tile, the cured coating layer including the curable coating composition of the disclosure.

A manufacturing process, and related products, for fabricating translucent articles in the form of tiles. The manufacturing process includes holding together a stack of corrugated cardboard pieces and saturating the cardboard pieces with an impregnating agent. Additional steps may include machining the cardboard pieces to define a block of a desired shape, slicing the block into tile components, and/or coating one or more tile components with a coating material to produce the article. Articles include translucent tiles made of corrugated cardboard pieces saturated with an impregnating agent. The tiles may be arranged to define a surface, such as a floor, a wall, a roof, a lighting installation, an architectural construction element, an architectural aesthetic element, or a solar panel.
