Mat-faced board and method for producing board
The application concerns a gypsum board (10) and a method of producing it whereby the board comprises a gypsum core (20) and at least one mat (12) being provided on the core. The mat has outer (14) and inner (18) surfaces and comprises a first region (30) adjacent to the outer surface defined along a horizontal plane of the mat, the first region having a first substantial thickness, and a second region (32) adjacent to the inner surface defined along a horizontal plane of the mat, the second region having a second substantial thickness. The first region has more hydrophilicity than the second region, more wettability than the second region, and/or less density than the second region.
