Prerequisites for the appearance of condensate on plastic windows

The prerequisite for the appearance of condensate on the design of the windows is explained by the fact that in the heating period the temperature of the room does not meet the necessary norms – it is much lower than the mark +20 ° C. Because of this, cold air accumulates in the lower part of the frame between the glasses, since these places are the coldest. This phenomenon is caused by the presence in the design of the aluminum frame, as well as the process of air convection in the double -glazed window.

In addition, condensate can also appear if the double -glazed window has a low heat transfer resistance that does not meet the required norms. It is possible to violate the back of the backlash, and the use of non -standard insulation. Another window can be blown out as a result of improper installation of loops. Condensate can also occur due to unsuccessful installation. For example, the mounting seam could be made incorrectly – the foam did not penetrate into the entire cavity, and thereby there was a decrease in the resistance of heat transfer. In addition, the seam can be poorly protected from the outside, while blowing the foam and its swelling occurs. The absence of vapor barrier in general can be the result of the insulation from the outside. Incorrectly carried out adjustment leads to the formation of cold “bridges”, and the condensate stands out very abundantly.

Having produced air directly through the walls, if there are empty seams. This phenomenon is found not only in old buildings, the seams were filled especially poorly during construction, but also in modern ones, in which mineral slabs are usually installed. The insulation ventilation occurs, and as a result, it is subject to cold flows. To prevent such a situation, when installing, it is necessary to separate the mounting foam and the adjacent area of ​​the window.
