Gypsum Panel Containing Additives for Improved Fire Resistance
The present invention is directed to a gypsum panel and a method of making such gypsum panel. For instance, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core. The gypsum core includes gypsum, a thermal insulation additive, and a shrinkage reduction additive. The gypsum core includes 3 wt. % or less of vermiculite based on the weight of the gypsum in the gypsum core. The gypsum panel passes ASTM E119-20.
