Humid Wall: Review on Causes and Solutions
Due to having airtight buildings, humid or wet walls have become a common problem in the last decades. Some common consequences of having humid walls is the growth of mold, which has a bad impact on the health and the comfort level of the internal environment. There is evidence that the effect of humidity on health is strong. Furthermore, the moisture content of the wall has a direct impact on its thermal resistance. This is due to the increase of thermal conductivity value of the wall. Briefly, the humid wall problem has a direct consequence on both energy consumption of the heating system and the health of the occupants. Hence, preventing and fixing humid wall problem is a challenge that is worth a closer investigation. Humid walls can be a result of an external reason; namely external moisture enters the building through the envelope of the building. Alternatively, the moisture that comes from cooking, bathing, washing, and people can constitute an internal cause of humid walls in buildings with poor ventilation system and low insulation level. The current paper studies the causes of humid walls and the possible solutions. Comparisons between different solutions are made.
