In this paper a method is presented for calculating the internal condensation front in roof constructions and that is applied not only to single layer wall, but to multilayer wall. In this method moisture transport in vapor and liquid phase in porous materials insulating vaper on the low temperature side is considered. Using this method, movements of condensation front of cellular concrete in following cases are calculated, during about ten years, under conditions which the indoor temperature and humidity is constant and the outdoor temperature is changing cyclically with a year period, and the results are compared with each other and are analyzed. Cases are as follows : 1. A material with uniform thermal conductivity and the case which the saturated vapor pressure in it is expressed by Goff-Gratch's formula. 2. A material with uniform thermal conductivity and the case which the saturated vapor pressure is expressed by a linear equation of temperature. 3. A material with different thermal conductivity in dry and wet layer and the case which the saturated vapor pressure is expressed Goff-Gratch's formura.
