First Claim
Patent Images
1. A building material comprising:
- a wallboard paper sheet;
a core matrix comprised of a plurality of microparticles having a generally spherical shape and a hollow interior, and at least one binder for adhering said microparticles together, said core matrix defining first and second surfaces, wherein the first surface of the core matrix is disposed on the sheet, wherein the second surface of the core matrix is an exposed rough surface so as to expose a portion of the plurality of microparticles and the at least one binder; and
a multi-elevational surface configuration formed in at least a part of said exposed rough surface of said core matrix that is configured to enhance the sound attenuation properties of said building material.

Abstract
A utility material can include microparticles, an organic binder and an inorganic binder. The microparticles can be present in an amount from about 25 wt % to about 60 wt %, based on wet formulation. The inorganic binder can optionally include sodium silicate. The organic binder can optionally include a vinyl acetate. The utility material can be formed into a variety of different products or building materials, such as wallboard, shear panels. In addition, the building material may be particularly used to attenuate sound.
