摘要： The present invention is directed to a gypsum panel and a method of making a gypsum panel. The gypsum panel comprises a gypsum core and a facing material. The gypsum core includes gypsum, a foaming agent, and optionally starch in an amount of less than 4 wt. % based on the weight of gypsum. The gypsum core includes air voids having an average void size of 50 microns or more. The gypsum panel has a density of 33 pcf or less, a weight of 1,800 lbs/MSF or less, and an NRC value of 0.2 or more.

摘要： A sound damping wallboard and methods of forming a sound damping wallboard are disclosed. The sound damping wallboard comprises a gypsum layer with a gypsum surface having an encasing layer. The encasing layer is partially removed to expose the gypsum surface and form a gypsum surface portion and a first encasing layer portion on the gypsum layer. A sound damping layer is applied to the gypsum layer to cover at least part of the gypsum surface portion and the encasing layer portion.

摘要： In general, the present invention is directed to a gypsum board comprising a gypsum core and a glass mat facing material including a coating. The coating comprises a resin including an acrylic resin, a siloxane rubber, or a mixture thereof and hydrophobic additive comprising an organosilane. The gypsum board passes at least one of the three air and water barrier tests specified in AC-212 wherein the tests comprise a water penetration barrier test as conducted in accordance with ASTM E331-00, a hydrostatic head test as conducted in accordance with AATCC 127-2008, or an air barrier test as conducted in accordance with ASTM E2357-11.
