The purpose of this research was to examine methods of protecting various insulated steel stud and exterior gypsum wall systems when exposed to condensation conditions. To fulfil this purpose, eighteen different wall panels were exposed to laboratory-controlled, freezing and non-freezing temperatures and 100% relative humidity conditions at the exterior gypsum sheathing surface"--Executive summary.
