• Temperature
• Humidity

Quite common life situations are fogging of glasses when leaving the room, glass in the bathroom or windows in the apartment. Condensation is a problem that millions of people face. It is quite easy to identify the cause of this phenomenon if you consider several options.

The main reasons for the appearance of condensation on metal-plastic windows, i.e. fogging are two factors - humidity and temperature. It is the change in these values, from a scientific point of view, that can affect this situation. For example, if you raise the humidity at a constant temperature, or, conversely, at a constant humidity, lower the temperature, you will achieve the phenomenon of misted windows. This is due to the fact that this surface in the apartment is the coldest, in the case of windows. And often the problem of condensation formation is encountered precisely in winter, due to the significant difference in temperature and humidity.

Temperature

Why do windows fog up due to temperature? This difference in different rooms is due to several reasons - external and internal. The first is wind action. In the case when the window faces the blown side, it will be colder than the window that faces the courtyard. The internal reason includes the assignment of batteries in different rooms to several risers and a different degree of access of warm air from the glass to the batteries. To avoid fogging the windows, it is necessary to choose the right glass unit. If your apartment has a single chamber, replace it with a two-chamber one. Also check the access of warm air from the battery to the windows. Very often, it is wide window sills, screens, etc. serve as a barrier. By increasing the temperature of the inner surface of the window, you will avoid the problem of condensation and will stop “sweating”.

Humidity

Why do metal-plastic windows sweat due to moisture? Increased room humidity must be brought to a normal level. As a rule, this factor is overestimated after repair work (for example, concrete, plaster, wallpaper). In this case, ventilate the apartment regularly. If you live in a private home, check your hood. Perhaps it is outdated and it is time to replace it.
