The appearance of moisture on the windows is a fairly common problem. And there are many reasons for this problem and options for combating it. The problem is that as a rule on the surface of the window from the inside, the temperature is less than inside. The air of low temperature reaches the temperature of the “dew point”, and the warm stream of air of the room condenses into dew. “The dew point” depends on atmospheric pressure, t and relative humidity.
There are the following bases of cold temperature near the window.
In the event that walls and slopes without insulation, then cool air blows inside without problems and is the basis of condensate. This problem is solved by warming the wall outside.
The reason may be a poor -quality window installation. Then you should contact the management of the company and ask to adjust the problems.
Excessively wide window sills can also become the basis for a warm air deficiency near the window. They block access to warm air flows from batteries.
Inexpensive, low quality window. In addition, a small number of cameras in the double -glazed window. Chambers at least need 2.
