Abstract

The present invention is directed to a gypsum panel and a method of making such gypsum panel. For instance, in one embodiment, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core, wherein the gypsum core includes gypsum and an alkoxylated compound. In another embodiment, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core, wherein the gypsum core includes gypsum and a polyol compound and wherein the gypsum panel exhibits a humidified deflection of greater than 0 inches to 0.05 inches. The methods of the present invention are directed to making the aforementioned gypsum panels by providing the first facing material, providing a gypsum slurry comprising gypsum, water, and the respective compound onto the first facing material, and providing the second facing material on the gypsum slurry.
