In certain embodiments, building panels and surface covering systems have superior fire resistant qualities.

A sound damping wallboard for installation on an installed wallboard, a sound damping wallboard system, and a method of constructing a sound damping wallboard on a building structure are disclosed. The sound damping wallboard includes a gypsum layer having a gypsum layer inner surface and a gypsum layer outer surface, a first sound damping layer disposed at the gypsum layer inner surface and having a first sound damping layer inner surface opposite the gypsum layer inner surface, a first encasing layer disposed at the gypsum layer outer surface, a second encasing layer disposed at the first sound damping layer inner surface, and a second sound damping layer disposed at the second encasing layer opposite the first sound damping layer inner surface.

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.

A sound absorbing panel assembly comprising the woven basalt material. The sound absorbing panel assembly comprises a height, a width, a length, a cover and an absorbent panel. The cover comprises a woven basalt material. The absorbent panel comprises a sound absorbent acoustic panel. The absorbent panel is covered by the cover.

Described herein is a building panel and related building systems, the building panel having a first major surface opposite a second major surface, the building panel comprising a core comprising a first body comprising a first fibrous material; and a second body comprising a second fibrous material, a veneer facing layer coupled to the core, the veneer facing layer comprising a plurality of perforations.

An acoustic panel comprises a mounting element and an acoustic damping element. The mounting element is adapted to be mounted to a wall or another structure of a building, and comprises a plurality of protrusions extending from a front side of the mounting element. The acoustic damping element comprises a rear face with a plurality of openings, and is adapted to be mounted to the mounting element with the plurality of protrusions fitting into the plurality of openings to hold the acoustic damping element in place at the mounting element. An acoustic panel system comprises a plurality of acoustic panels and a plurality of connecting brackets.

Disclosed is a building board construction that provides enhanced acoustical properties. In one possible embodiment, the board is a gypsum board with opposing facing sheets and an intermediate set gypsum core. An opened celled polymeric sheet is formed within the gypsum core and gives the resulting board enhanced sound absorption. In an alternative embodiment, individual pieces of polymeric foam are used in stead of the polymeric sheet. Also disclosed are various manufacturing methods whereby boards with enhanced acoustical properties can be formed in an continuous process. The various components of the present disclosure, and the manner in which they interrelate, are described in greater detail hereinafter.
