Description
Microporous surface materials are put forward to prevent condensation on subfloor in some building design standards and specifications in China. However, in the current study there are mostly applied cases, lacking of quantitative research. This paper simulated and compared the surface wet condition of three different surface materials by WUFI software: solid brick, hardwood and glazed tile brick. The results shows that the time on surface relative humidity that above 95%, hygroscopic subfloor reduces by more than 20% over non-hygroscopic subfloor, and the improvement is over 45% in relative humidity range of 99% to 100%. In high-humidity areas such as Chongqing, it is suitable to use the porous hygroscopic material which moisture absorption capacity rapidly increases when the environment humidity exceed 80%, and absorbs little moisture lower than 80%.
