Abstract: Air purification and surface sterilization systems employing ultraviolet germicidal irradiation integratable in a discrete manner into indoor occupiable spaces in buildings. The systems may be used alone or in combination. The air purification system utilizes fan-powered disinfection units equipped with an ultraviolet light source operable to deactivate airborne pathogens. The surface sterilization system utilizes ultraviolet lamp units operable to deactivate surface accumulations of pathogen. Devices of either disinfection system may be integrated into ceiling or wall systems of the building interior space, or office furniture used in such spaces. The systems have applicability to institutional, commercial, and residential facilities as some examples.

Abstract: A ceiling system includes a ceiling support structure supporting a plurality of ceiling panels, each ceiling panel including a core layer having a top surface facing a first interior space above the ceiling panels, a bottom surface facing a second interior space below the ceiling panels, and a plurality of peripheral edges extending between the top and bottom surfaces. A top frame layer extends from the top surface and a thermal layer is on the top frame layer opposite the top surface. The thermal layer has a first surface facing away from the top frame layer and a second surface facing toward the top frame layer. The top frame layer supports the second surface in a spaced-apart manner from the top surface to form one or more air gaps between the top surface and the second surface. The first and second surfaces have a thermal emissivity of 0.5 or less.

Abstract: This invention is an acoustic fiber-based substrate composed primarily of insulation-type spun fibers or blends of such fibers and wheel spun fibers. The fibers are bound with a water-dispersible latex binder, or an agri-binder such as starch in conjunction with cellulose fiber. The insulation-type spun fibers can be first quality virgin, post-industrial waste-stream or post-consumer waste stream fiber. The substrate is wet-formed from a very dilute aqueous dispersion of ingredients onto a mesh forming screen, as on a Fourdrinier paper machine. By virtue of the insulation-type spun fiber dimensions, morphology and orientation: very low density wet-mats can be formed from a sufficiently dilute suspension. With respect to other wet-formed substrates, the invention is much lower in density and more highly porous, and, thus, the substrate is highly absorbing, exhibiting noise reduction coefficients, NRC values of about 0.80 or greater.

Abstract: The present invention provides for an acoustically absorbent porous panel that is both rigid and resistant to sagging caused by moisture. The acoustically absorbent porous panel is comprised of at least two layers. The first layer is a facing layer formed from a cured aqueous foamed cementitious material. The foamed cementitious material comprises on a wet basis about 53% to about 68% by weight cement, about 17% to about 48% by weight water, about 0.05% to about 5% by weight fiber, and about 0.01% to about 10% by weight surfactant. Additionally, pores distributed within the cured material comprising about 75% to about 95% by volume of the material. The second layer is a backing layer that is affixed to the facing layer.
