FIELD: construction.
SUBSTANCE: gypsum board includes gypsum matrix containing polymer additive distributed in it in amount of at least 1 wt. % with respect to gypsum, wherein gypsum matrix further comprises a first group of fibres - glass fibres, and a second group of fibres - cellulose fibres immersed therein, where the average fibre length of the first set of fibres is at least three times greater than the average fibre length of the second set of fibres. Invention is developed in dependent claims.
EFFECT: technical result is improved ability of panel to retain fasteners, as well as high strength of panel and reduced density.
