Patent

CA 2487159

The present invention relates to a gypsum board having a nonwoven liner and a gypsum core. The gypsum board of the present invention has a high work to break, resulting in a gypsum board product that has a high resistance to abuse in use. The gypsum board of the invention is also more flexible and more resistant to water and fire than paper-lined gypsum board, and does not contain nutrients that support mold growth.

L'invention porte sur un panneau de plâtre revêtu d'un doublage de non tissé présentant d'une part une forte résistance à la rupture et donc aux effractions, et d'autre part une plus grande flexibilité et une meilleure résistance à l'eau et au feu que les panneaux à doublage de carton, sans par ailleurs contenir d'éléments favorisant les moisissures.
