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.
