Gypsum board suitable for wet or humid areas

The present invention relates to a gypsum board having a core， the core having at least one side covered with a nonwoven material; The inner surface of the nonwoven material is in contact with the core of the gypsum board and has a surface roughness (Ra) of 25 μm to 60 μm， preferably 25 μm to 50 μm， advantageously 25 μm to 40 μm. do. Gypsum board having a core， said core having at least one side covered with a non-woven fabric; characterized in that the inner side of the non-woven fabric， which is in contact with the core of the gypsum board， has a surface roughness Ra of from 25 to 60 micrometers， preferably from 25 to 50 micrometers， advantageously from 25 to 40 micrometers.
