FIELD: manufacturing technology.
SUBSTANCE: invention relates to a fibrous facing mat for making a gypsum board, to a gypsum panel containing the said facing mat, and to a system containing the above gypsum board. Fibrous mat contains at least one layer of non-woven material and a binder composition. Binding composition is 10–40 wt% of mat weight. Binding composition contains a copolymer containing a comonomer link of a vinyl ester of an alpha-branched aliphatic monocarboxylic acid, and said copolymer is present in amount of 25–100 wt% of weight of binder composition.
EFFECT: improved characteristics of adhesion between gypsum core and mat, while maintaining mechanical strength.
