摘要： The present invention is directed to a gypsum board and a method of making such gypsum board. In one embodiment, the gypsum board comprises a gypsum core including a first gypsum core layer and a second gypsum core layer sandwiching a laminate layer. The laminate layer comprises two outer laminate layers sandwiching an inner laminate layer, wherein the two outer laminate layers have a higher elastic modulus than the inner laminate layer. The method of making the gypsum board includes steps of providing facing materials and corresponding gypsum slurries wherein the laminate layer is provided in-line during the manufacturing process of the gypsum board.
