  • Plaster-based acoustic board
    Patent number: 11162257
    Abstract: A plaster-based board includes a core made of plaster positioned between two coating layers, in which a textile including glass fibers and an organic binder constitutes at least one of the coating layers and/or the textile is embedded in the plaster constituting the core. In the textile, the binder includes one or more organic polymers having a glass transition temperature which varies from ?10 to +25° C., measured by differential scanning calorimetry according to the standard ISO 11357-1:2009.
    Type: Grant
    Filed: January 11, 2017
    Date of Patent: November 2, 2021

  • Acoustic panel made of plaster
    Patent number: 9868269
    Abstract: A plaster-based board includes a plaster-based core positioned between two sheets of paper or nonwoven fabric, wherein the core contains at least one polymer selected from polyvinyl butyral (PVB), copolymers of vinyl acetate and an olefin, which copolymers have a glass transition temperature that varies from ?10° C. to +25° C., terpolymers of vinyl acetate, an olefin and a vinyl ester monomer, terpolymers of vinyl acetate, a vinyl ester monomer and a (meth)acrylate monomer, and copolymers of vinyl acetate and an acrylic monomer.
