Abstract

A high temperature sag resistant lightweight wallboard. The addition of a small amount of urea (about 0.1 %) significantly improves the high-temperature sag resistance on Type X gypsum wallboards. These gypsum wallboards may have a board weight of less than 2100 Ibs/msf when cast to have an overall 5.8 inch thickness, and may include glass fibers and/or mineral wool. Also, methods of making the gypsum wallboard and a wall system for employing the gypsum wallboard.
