    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.
