This study focuses on the comprehension of internal condensation behaviour in wall parts of buildings. In this paper the internal moisture behaviour in Calcium Silicate Board under the processes of condensation and reevaporation is studied. Properties of this material regarding moisture transfer were measured. Experiment and analysis of the condensation and re-evaporation processes were conducted. The results and the effects of variations in properties and conditions on the analysis are also discussed and are compared with those of Cellular Concrete Board. lt is proved that the effect of the variance of material properties and the air conditions on internal condensation, in higher moisture content region, is larger than in lower moisture content region. It is also proved that in the conditions used in this paper, the moisture content of Calcium Silicate Board reaches a low moisture content in a steady state during the condensation process while that of Cellular Concrete reaches a high moisture content.
