IMPROVED MAT AND RELATED GYPSUM BOARDS SUITABLE FOR WET OR HUMID AREAS
The invention relates to a fibrous mat facer for preparing a gypsum board, to a gypsum board comprising said mat facer and to a system comprising said gypsum board. The mat facer of the present invention shows an improved inner cohesion strength. It also exhibits lower grammage, lower thickness more air porous and higher tensile and flexural strength, thus is lighter and stronger than the known ones. It may have a certain lower surface roughness and an embossing pattern, which makes it is not only tightly bound to the gypsum core regardless of the gypsum composition and/or the presence of additives but is easier and safer handled and transported as well. The plasterboard thereof is suitable for external and internal applications. It is particular suitable for being used as external sheathing and for building or renovation material in a bathroom, a kitchen, a laundry room, and in any room that may be exposed to humidity or even in outdoor applications.
