Abstract: The present invention provides an improved lighting fixture 10. The lighting fixture 10 is an acoustical lighting fixture which may be suspended below a deck 14. The lighting fixture 10 can be suspended below the deck by placing the fixture on a T-bar grid 16 of a drop ceiling 12. The acoustical lighting fixture 10 includes an acoustical shell 30 having an electrical light source 32, such as a fluorescent tube, removably mounted on the acoustical shell 30. The acoustical shell 30 may be constructed from a fiberglass material or a perforated metal material. The acoustical lighting fixture 10 also includes an acoustical, sound absorbing blanket 26 that absorbs sounds that strike the acoustical lighting fixture 10.The acoustical lighting fixture 10 may also include a louver 28 which encloses the electrical light source 32 within the acoustical shell 30.

Abstract: A lay-in ceiling panel structure, comprising a glass fiber ply, a gypsum board, and a highly perforated vinyl lamina. The ceiling panel structure having noise and sound transmission reduction coefficients in the range of 0.85 to 0.95 sabins and 0.35 to 0.39 dbs respectively. This structure also provides good fire resistance, space efficiency, and a lower surface that is washable and pleasing to the eye. In addition, the glass fiber ply is secured to the gypsum board by droplets of glue which are spaced 1 to 2 inches apart and which are applied 4 to 6 inches away from the outer periphery of the gypsum board. Applying the glue in this way allows the glass fiber ply and vinyl lamina to lay flat even if the board is warped by water leaks, humidity or age.

Abstract: An acoustical panel structure having a honeycomb core, and thin, dense, sound transmitting glass fiber mat of uniform thickness adhered to each of the opposed major surfaces of the core. A glass fiber sheet of greater thickness than the mats is secured to the outer surface of one of the mats. A decorative coating or layer is provided on the glass fiber sheet. The resulting structure has a noise reduction coefficient of upwards of 75, and a flame spread of less than 25.

Abstract: A demountable acoustical panel structure having a honeycomb core, and a thin, dense, sound transmitting glass fiber sheet of uniform thickness adhered to each of the oposed major surfaces of the core. One of the thin sheets advantageously carries segments or patches of a separable fastening means to enable the panel structure to be installed on a supporting surface provided with cooperating segments or patches of a separable fastening means by simply aligning said fastening means.

Abstract: A tackable acoustical structure comprising a tack pin retaining layer, a sound absorptive layer, and a metal foil septum separating the tack pin retaining layer and the sound absorptive layer. The structure can be formed into wall panels having a flame spread index which qualifies them as a Class A rated building materials.

Abstract: An acoustical panel construction which, in its preferred form, comprises a preformed body portion or shell, the outwardly extending edges of which are formed of thin, but dense, acoustical material. The density, thickness and configuration of the edges provides the necessary rigidity and structural strength to enable a panel formed from the body portion or shell to be properly edge supported on, and conform to, a grid system. The body portion or shell advantageously is formed with a central area of acoustical material which is thicker, but less dense than the edge areas, to enhance the acoustical properties of the finished panel. The body portion or shell is adapted to receive a sheet or layer of an acoustical material having a preselected density and thickness such that the finished panel will be able to meet the sound absorption and resistance to fire, among other demands, of the environment in which the panel is installed.

Abstract: A unitary structural panel for ceiling and wall installations has a dimensional stability and structural strength to be edge supported as a unit without sagging or warping, a high impact resistance, a good fire rating and easy washability. It comprises a relatively thick fabricated panel which of itself may be subject to sagging or warping or impact damage or fire damage or soil damage, and a relatively thin and flexible laminated facing for the fabricated panel. The thin and flexible laminated facing includes a metallic film, a glass fiber scrim and a synthetic plastic film adhesively secured together with the scrim between and bonded to the metallic film and the synthetic plastic film and with the metallic film bonded to the synthetic plastic film within the openings in the scrim. The laminated facing is adhesively secured to the fabricated panel with the metallic film thereof bonded to a face of the fabricated panel and with the synthetic plastic film thereof exposed.
