Modules with variable acoustic properties configured for covering boundaries, such as walls or ceilings of a room, for instance a multi-purpose room, in which it must be possible to change the acoustical properties of the room, such as the reverberation time, according to each specific use, where the module has a front face provided with one or more through-openings through which sound energy can enter an inner region of the module, and where the module in the inner region comprises a sound absorbing device in acoustic communication with the through-openings in the front face such that sound energy can pass from an exterior region or space outside the module to said sound absorbing device, where the through-openings can be closed, such that sound energy cannot enter the sound absorbing device and opened, such that sound energy can enter the sound absorbing device.

Described herein is a ceiling panel assembly comprising a panel body having an inner surface defining an internal cavity having a first open end defined by a first side edge of the panel body, a first end cap comprising a face plate, an insertion portion extending from an inner surface of the face plate, and a concealment portion extending from the inner surface of the face plate; and the first end cap coupled to the panel body so that: (1) the insertion portion extends into the internal cavity; (2) the concealment portion wraps around at least a portion of the first edge and is adjacent an outer surface of the panel body; and (3) the end face plate encloses the first open end of the internal cavity, and the first end cap is coupled to the panel body by frictional fit.

A ceiling structure includes a suspended framework having a plurality of main runners and a plurality of cross runners interconnected to define an array of tile receiving openings, each of the plurality of main runners and the plurality of cross runners including a tile mating surface facing downward to define a mounting frame at each respective tile receiving opening, and a plurality of ceiling tiles positioned within the array of tile receiving openings, each of the plurality of ceiling tiles having a main body. The main body of the ceiling tile includes a base having a periphery, a plurality of magnets positioned at the periphery and sized and shaped to magnetically couple the ceiling tile within a respective one of the tile receiving openings, and a plurality of baffles coupled to the base, each baffle being spaced apart from the other. Related methods, systems, and ceiling tiles are also provided.

A sound absorbing panel and method therefor comprising providing a first sheet of photosensitive material, applying a first mask having a first plurality of features to the first sheet of photosensitive material, exposing the masked material to ultraviolet light, heating the first sheet of photosensitive material to form crystals in exposed portions of the first sheet, and etching the crystals to form a second plurality of features in the first sheet of photosensitive material.

A dynamic acoustic system for use in connection with an indoor environment includes a plurality of elongated acoustic bars and a controller operably to each of the elongated acoustic bars. Each of the bars is operably coupled to a ceiling member of the indoor environment and includes an upper portion, a lower portion, a plurality of side surfaces extending between the upper and lower portions, an interior region at least partially defined by the upper portion, the lower portion, and the plurality of side surfaces, and at least one movable element movable between first and second positions. The controller selectively controls operation of the at least one movable element of a desired number of the plurality of elongated acoustic bars to alter an environmental characteristic of the indoor environment.

A ceiling system for use in an interior building environment. In one aspect, the invention may be a ceiling system comprising: a frame comprising a plurality of struts; a plurality of modules, each of the modules comprising a panel and a plurality of hook members coupled to and extending from a top surface of the panel; each of the hook members comprising: an upstanding section; a hook portion at a top end of the upstanding section, the hook portion defining a downwardly-facing open slot; and an attachment flange at a bottom end of the upstanding section that couples the hook member to the top surface of the panel; and the modules mounted to the frame, and wherein for each of the modules, the hook portions of the hook members fit over and rest upon the struts, the struts located in the downwardly-facing open slots of the hook portions.

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.

Decking with a panel of uniform thickness sheet metal has a repeating pattern of top flanges and bottom flanges connected by webs therebetween. At least one flange is made up of a plurality of folded-layer segments adjacent to each other in a stacked position to increase the thickness of the flange. Additionally a structural member extending along a longitudinal axis has a uniform thickness plate folded back onto itself about the longitudinal axis or an axis parallel to the longitudinal axis to increase the thickness and provide greater resistance to buckling in response to compressive forces. Such structural members not only provides certain structural advantages but also may provide an aesthetically pleasing appearance.

An integrated ceiling and light system that incorporates a light module into a ceiling tile. The system may include a grid support system suspended from an overhead support structure that includes at least one grid support element and first and second ceiling tiles supported by the grid support element in an adjacent manner A nesting cavity may be formed into the first and second ceiling tiles such that a light module may be disposed within the nesting cavity and coupled to the first and second ceiling tiles. The ceiling tiles may be of the type that conceals the grid support element on which it is supported. In one alternative embodiment, the light module and a nesting region of the ceiling tile may include corresponding edge profiles to facilitate mating therebetween to enable coupling of the light source to the ceiling tile.
