Isotherms of water vapor sorption by light inorganic and polymer heat-insulating materials

Abstract

This paper presents the results of an experimental study of the isotherms of water vapor sorption by glassfiber and mineral-wool products, expanded polystyrene plates, and ecowool. It has been shown that the equilibrium specific moisture content of glass-fiber and mineral wool products depends on the binder content and density and that of expanded polystyrene plates is density-dependent.
