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.

A ceiling façade system includes: a ceiling tile including an interior panel defining a first edge extending along a first side of the ceiling tile and a second edge extending along a second side of the ceiling tile opposite the first edge, a heating element, and an insulator layer arranged over the heating element opposite the interior panel; a first receiver extending along and configured to support the first side of the ceiling tile on a linear lighting track arranged on a ceiling structure and configured to locate the first edge of the interior panel adjacent and partially concealing the linear lighting track; and a second receiver extending along and configured to support the second side of the ceiling tile on a linear seam track arranged on the ceiling structure, the linear seam track laterally offset from the linear lighting track.

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.

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.

Described herein is a method for forming a monolithic surface in a ceiling system, the method comprising overlapping a first facing sheet and a second facing sheet to create an overlap region, each of the first and second facing sheets having a first major surface opposite a second major surface and side surface extending between the first and second major surfaces, wherein the lower surface of the first facing sheet contacts the upper surface of the second facing sheet within the overlap region, and running a blade of a cutting tool along the overlap region such that the blade extends through the first and second facing sheets at a cutting angle that is oblique to the first major surface of the first facing sheet within the overlap region.

A ceiling façade system includes: a ceiling tile including an interior panel defining a first edge extending along a first side of the ceiling tile and a second edge extending along a second side of the ceiling tile opposite the first edge, a heating element, and an insulator layer arranged over the heating element opposite the interior panel; a first receiver extending along and configured to support the first side of the ceiling tile on a linear lighting track arranged on a ceiling structure and configured to locate the first edge of the interior panel adjacent and partially concealing the linear lighting track; and a second receiver extending along and configured to support the second side of the ceiling tile on a linear seam track arranged on the ceiling structure, the linear seam track laterally offset from the linear lighting track.

A structural grid support system adapted for transferring seismic loads to the vertical structural supports of a modular structure. The system includes larger and longer high load capacity main runners with mechanically fastened cross tees, which transfer seismic forces without failing. The structural grid can provide a diaphragm using mechanically fastened connections in a single horizontal plane without requiring additional overhead support from the roof deck, or requiring fewer such supports. The main runners may include additional connecting elements disposed within the usable space beneath the runner (e.g., ventral threaded receivers) for attaching deployment-specific equipment or hardware, such as network cable trays.

An integrated ceiling and light system that incorporates a light module into a ceiling tile. The system may include an acoustic ceiling tile and a light module magnetically coupled to the acoustic ceiling tile.

Described herein are mineral fiber compositions having enhanced characteristics, such as biopersistence and resistance to heat induced shrinkage. Also described are methods for making and using the same. Such compositions may comprise manganese oxide and aluminum oxide.

A luminaire module includes a support structure configured for an overhead or region of a defined space suitable to support the luminaire module. The support structure may support a plurality of panels with each defining an illuminatable presentation surface, the plurality including at least one first panel including a first peripheral region. The first panel may be inclined at a first angle of less than 90 degrees from a first reference plane, and one or more second panels, each of which being oriented to be upright at a second angle of less than 90 degrees from a second reference plane. The luminaire module may be configured to be assembled in an array with the presentation surfaces in the array providing a composite image in three dimensions formed by a plurality of image segments provided by the presentation surfaces of the modules in the array.
