Abstract (en)
[origin: CA3009134A1] The present invention relates to a plaster-based board comprising a core made of plaster positioned between two coating layers, in which a textile containing 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 said textile, the binder comprises one or more organic polymers having a glass transition temperature which varies from -50 to +80°C measured by differential scanning calorimetry according to the standard ISO 1357-1:2009.
