Abstract

L'invention concerne un panneau léger résistant à l'affaissement à haute température. L'ajout d'une petite quantité d'urée (environ 0,1 %) améliore significativement la résistance à l'affaissement à haute température sur des panneaux de gypse de type X. Ces panneaux de gypse peuvent avoir un poids de panneau inférieur à 2100 Ibs/msf lorsqu'ils sont coulés pour avoir une épaisseur globale de 5,8 pouces, et peuvent comprendre des fibres de verre et/ou de la laine minérale. L'invention concerne également des procédés de fabrication du panneau de gypse et un système de paroi pour utiliser ce panneau de gypse.
