Abstract
A method of detecting an air gap in a gypsum-based building board includes cooling a surface of a gypsum-based building board that has generated heat because of a hydration reaction of calcined gypsum by applying a cooling medium to the surface, and detecting a temperature distribution of the surface of the gypsum-based building board after completion of the cooling.
