Abstract: Described herein are building panels and surface covering systems useful for spaces requiring acoustic control and design flexibility, and methods to prepare the same. Such building panels and surface covering systems comprise an building panel having a first major surface opposite a second major surface and a side surface extending there-between, the acoustic building panel comprising a body having an upper surface opposite a lower surface and side surfaces extending there-between; backing having a first side opposite a second side and comprising denim web and a low-melt polyester bicomponent fiber; wherein the first side of the denim web backing is in contact with the upper surface of the body; and wherein the denim web backing has a web basis weight from about 1150 to about 1350 g/m2. In certain embodiments, building panels and surface covering systems have superior fire resistant qualities.

Abstract: Described herein are compositions useful for infusing color into nonwoven polyester containing product and methods to do so. Such compositions and methods comprise use of a color infusion composition comprising an antimigrant polymer; pigment; ammonium polyphosphate; and an anionic surfactant comprising phosphate. In certain embodiments, thermoplastic polymer having a glass transition temperature (Tg) of 93.0° C. or less is used to enhance color infusion.

Such building panels and surface covering systems comprise an acoustic building panel having a first major surface opposite a second major surface and a side surface extending there-between, the acoustic building panel comprising a body having an upper surface opposite a lower surface and side surfaces extending there-between; a fleece having a first side and a second side; wherein the first side of the fleece is in contact with the upper surface of the body; wherein the body and fleece are laminated; and wherein the fleece has a resistivity of about 826,100 to about 1,090,900 Pa*s/m2. In certain embodiments, building panels and surface covering systems have superior fire resistant qualities.

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.
