The disclosure provides a ceiling tile including a curable coating composition including 10-50 vol. % inorganic binder, based on the total volume of solids in the dry coating composition, wherein the inorganic binder is an alkali metal silicate or an alkaline earth metal silicate and 50-90 vol. % inorganic filler, based on the total volume of solids in the coating composition, wherein the binder and the filler are not the same and the coating is substantially free of an organic polymeric binder. The ceiling tiles have a backing side and an opposing facing side, and a cured coating layer disposed on the backing side of the panel, the backing side being directed to a plenum above the fibrous panel in a suspended ceiling tile, the cured coating layer including the curable coating composition of the disclosure.

Described herein are acoustical panels, comprising: a substrate; a non-woven veil having an airflow resistance of greater than 45 mks rayls, comprising: from about 20 wt. % to about 60 wt. % glass fibers; from about 40 wt. % to about 80 wt. % of a filler; and from about 110 dry g/m.sup.2 to about 135 dry g/m.sup.2 of a coating. Methods of making and using the panels are also described.

An architectural fixture assembly including a generally U-shaped first beam having a bottom side, a first side, a second side, and a first end. Interior surfaces of the first, second, and bottom sides of the first beam define an interior portion. A connector includes a plate, and a connection key extending away from the plate. The interior surfaces of the first and second sides each include a generally V-shaped alignment notch disposed generally adjacent to the first end of the beam. The connection key includes a pair of generally V-shaped sides disposed on opposite sides of the connection key, and each generally V-shaped side is configured to slidably engage one of the generally V-shaped alignment notches.

A dynamic acoustic ceiling baffle and a dynamic acoustic ceiling baffle system, that includes multiple shaped baffles that can be quickly and easily installed onto construction ceiling hangers without the need for additional tools, to provide an aesthetically pleasing image, such as an undulating image, along with a reduction in unwanted noise or room acoustics.

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. One aspect of the disclosure is a method for preparing an acoustic panel comprising providing a base structure. The base structure has one or more edges, an outward major surface having a total are, 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.
