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 fibrous mat comprises at least one ply of a non-woven fabric, and a binder composition, wherein the binder composition represents from 10 to 40 wt % of the total weight of the mat. The binder composition comprises a copolymer comprising a co-monomer unit of a vinyl ester of an alpha branched aliphatic monocarboxylic acid, said copolymer being present in an amount from 25 to 100 wt % of the binder composition weight.

Mat and gypsum boards suitable for wet or humid areas

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.

Gypsum board suitable for wet or humid areas

A construction assembly for interior works including prefabricated elements, wherein the prefabricated elements include a coating layer formed of at least one skim coat deposited on the prefabricated elements by a coating device; and at least one jointing material, e.g. a sealing coat, joint coat and/or joint pointing coat, which joints adjacent said prefabricated elements to form a substantially plane outer surface.

Construction assembly of skim coated prefabricated elements and jointing material, a kit therefor, and method of assembling the same

The invention relates to a new plasterboard having a facer comprising two plies, and uses of such plasterboards in EIS or EFS.

Gypsum board and systems comprising it

A construction assembly includes a plurality of plaster boards, each of the plaster boards having a plaster body and at least one sheet of liner, the liner including an inner surface attached to the plaster body and an outer surface having an outer face; wherein said plaster boards are assembled creating at least one joint; and a joint-pointing coat jointing said plaster boards to form a substantially plane outer surface including the outer surface of said at least one joint and said outer surface of said liner, wherein the composition of the joint-pointing coat is adapted for the finishing of said at least one joint; wherein both the joint-pointing coat in the dry state and the outer face of the sheet of liner are adapted to form an overall surface having a substantially homogeneous coloration.

Construction assembly of plaster boards and a method of assembling a plurality of plaster boards
