A ceiling system is provided for use in a building space. The ceiling system has an open cell grid structure and is attached to a support structure of the building via hanging hardware. The open cell grid structure is constructed of a plurality of first panels attached to the hanging hardware, a plurality of second panels attached to the plurality of first panels, and a plurality of third panels attached to the plurality of second panels. The first, second, and third panels are attached via a plurality of slots which allow secure engagement and utilize gravity to retain them in the assembled condition. Beneficially, the plurality of second panels and the plurality of third panels are free of hanging hardware.

This invention relates to a suspended ceiling, comprising a metal grid structure and a plurality of drop-in ceiling panels supported by the metal grid structure. Each of the ceiling panels includes a thermal conductive metal substrate, a heat insulating coating formed on the top surface of the metal substrate, and a thermal conductive ceramic coating formed on the bottom surface of the metal substrate. The heat insulating coating is provided to prevent heat generated in a plenum space between the dropped ceiling and a actual ceiling from traveling down to the room below the dropped ceiling. And, the thermal conductive ceramic coating is provided to enhance a heat transfer capability of the metal substrate. As such, the ceiling panels can facilitate rapid cooling of an air-conditioned room.

Disclosed is a sound absorbing lighting panel (100) comprising a sound absorbing member (120); an optical medium (130) over said sound absorbing member; a first set (140) of solid state lighting elements (142) arranged along a first edge of said optical medium; a translucent sheet (150) over the optical medium, said translucent sheet having a non-uniform degree of translucency such as a higher degree of translucency over a central region of said optical medium than over a first region of said optical medium comprising said first edge. A modular surface system including such a sound absorbing lighting panel is also disclosed.

A suspended ceiling comprising SUSPENDED metal runners in a horizontal plane, the runners each having a horizontal flange having an effective vertical thickness, a plurality of rectangular drywall sheets aligned crosswise to the runners and screwed to the flanges with ends of the drywall sheets forming butt joints midway between adjacent runners, boards overlying butt joints and adjacent flanges, the boards being substantially stiffer than the drywall sheets, whereby the drywall sheet ends are drawn up towards an upper level of the flanges when screwed against the overlying board so that a pseudo taper is formed on the drywall sheet ends.

An acoustic housing, a light fixture, a suspended ceiling system, and a method of decreasing sound transfer from a light fixture in a suspended ceiling are disclosed. An acoustic hood for a light fixture in a suspended ceiling may include a partially enclosed space formed between a plurality of wall portions. A light fixture may include first and second layers that are coupled to one another and form a partially enclosed space. A suspended ceiling system may include the acoustic hood or light fixture. The method relates to disposing an acoustic housing spaced from the light fixture.

A ceiling system in one embodiment includes a support grid including intersecting grid support members and grid openings formed between the grid support members. A vertical baffle is positioned in a grid opening and is attached to the support grid. The baffle includes opposing front and rear faces extending between opposing lateral sides of the baffle. First and second mounting grooves formed in the baffle engage and support the baffle from the grid. In one embodiment, one of the mounting grooves is disposed in each lateral side to support the baffle from opposite sides. The baffle may further include a third mounting groove formed in the rear face which engages the support grid to help align and squarely register the baffle with respect to the grid for clean linear visuals. In one embodiment, the grid support members may have a standard T-shaped cross section.

A formulation for an acoustically transparent coating for use on an acoustical substrate comprising a water dispersible binder and relatively large filler particles, and characterized by a high pigment to volume concentration, high viscosity, high shear thinning, and fast drying to enable the formulation to be sprayed in droplets that retain their identity when in mutual contact.

The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a nonwoven facing and to methods for making such panels. A method for preparing an acoustic panel comprises providing a base structure. The base structure has one or more edges, an outward major surface having total area, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The method includes disposing directly against the outward major surface of the base structure a sprayable mixture comprising a plurality of fibers, one or more binders, and a dispersive medium. The method includes drying the disposed mixture to provide a facing layer disposed on the outward major surface of the base structure, the facing layer having an exterior major surface opposing the outward major surface of the base structure.

Systems and methods are disclosed for a multi-layered sound absorption structure. The multi-layered sound absorption structure may include a form material, an acoustic material disposed on a surface of the form material, and a construction material disposed on the acoustic material. The acoustic material may couple to the construction material during curing of the construction material. After the construction material is cured, the form material may be removed exposing a least a portion of the acoustic material.

An apparatus, method and system of insulating a building such as a poultry barn uses netting structurally of the type to hold sod together. The netting is stapled to the bottom of trusses making up the ceiling of a barn and the attic of the barn. Ceiling material is superimposed below the netting to form a ceiling. Loose insulation, typically fiberglass, is blown onto the netting to be held thereby and to form an insulation layer in the attic of the barn.
