There are three reasons for wall condensation: design, construction and use. The reasons for the design are as follows: although the wall meets the moisturizing requirements, the beam, plate and column have not been moisturizing treatment; Heating technology measures are not, radiator deployment is not proper; The convex Angle of the windward side of the exterior wall and the special-shaped column did not thicken the moisturizing layer, resulting in substandard insulation effect. The reasons for the construction are: the insulation material did not reach the thickness of the design; Strong cracking and ventilation; The seams between doors, Windows and walls are not sealed with moisture.
In view of the above problems, we should accept the addition of insulation layer, replace the original insulation material with high efficiency insulation material, and make moisture sealing treatment for ventilation. The condensation caused by improper use of the user should be prevented from getting too wet in the room. As long as the design, construction and use of the required, the problem of wall mildew can be completely prevented.
