Abstract:
(EN) One aspect of the disclosure is a plaster board having a first edge and an opposed second edge, and a third edge and an opposed fourth edge. The plaster board includes a first layer of hardened plaster material including a first surface and an opposed second surface, and a second layer of hardened plaster material including a first surface and an opposed second surface. The second layer of hardened plaster material is stacked against the first layer such that their first surfaces face one another. The first layer and the second layer together define the first, second, third, and fourth edges of the plaster board. The plaster board also includes a viscoelastic polymer disposed between the first surfaces of the first and second layers of hardened plaster material. The viscoelastic polymer does not extend substantially to the first, second, third, and fourth edges of the plaster board.
(FR) Un aspect de l'invention concerne une plaque de plâtre comprenant un premier bord et un deuxième bord opposé, et un troisième bord et un quatrième bord opposé. La plaque de plâtre comprend une première couche de matériau de plâtre durci comprenant une première surface et une seconde surface opposée et une seconde couche de matériau de plâtre durci comprenant une première surface et une seconde surface opposée. La seconde couche de matériau de plâtre durci est empilée contre la première couche de sorte que leurs premières surfaces se font face. La première couche et la seconde couche définissent ensemble les premier, deuxième, troisième et quatrième bords de la plaque de plâtre. La plaque de plâtre comprend également un polymère viscoélastique disposé entre les premières surfaces des première et seconde couches de matériau de plâtre durci. Le polymère viscoélastique ne s'étend sensiblement pas jusqu'aux premier, deuxième, troisième et quatrième bords de la plaque de plâtre.
