This is because the insulation is thin and waterproof, but it is easy to seep in summer and get cold in winter, which eventually leads to moldy walls. \r\n2。 In terms of construction \ r \ nIf the external wall tiles are not properly embedded and the brick joints are not filled, the wall will be moldy, because if the external filled wall is not filled with mortar, sand holes and cracks will appear, thus forming a cold bridge or a hot bridge, and if the joints between the wall and the beam and column are not filled, cracks will occur and the wall will eventually become moldy. \r\n3. Environmental factors \ r \ Because there is more rain and higher air humidity in summer in the south, it is easy to cause moldy walls. In addition, the winter climate in the northern region will be quite cold. Because the wall is cold, if the indoor temperature is too high, it is easy to cause condensation. If the external wall itself is not well insulated, it will also form a wall through cold, and the indoor water vapor will crystallize into water droplets on the wall, and finally the wall will be moldy and hairy. \ r \ Summary of the article: The above are all about whether moldy walls are harmful to people's health and what are the reasons for moldy walls, hoping to help everyone.
