As soon as the temperature on the street drops below a certain level, droplets of condensation begin to appear on the windows. At first they gather in the corners and at the very bottom of the frame, and then the smoke covers the whole window, making the glass almost dull. This interferes with the view and reduces the amount of daylight in the room. Dampness can have a bad effect on electrical wiring and even lead to the appearance of mold in the apartment. Therefore, the fogging of windows should be fought.

But in the beginning it is necessary to understand in detail the causes of this phenomenon. Basically, two circumstances are to blame: the glass temperature is much colder than room temperature, the air in the room is too humid. Warm air can hold much more water than cold. Colliding with the cooled surface of the glass, the vapor condenses into water, which settles in the form of droplets. It is this process that occurs when the windows mist over.

But the temperature difference occurs in all apartments, and only some windows suffer especially from mold. There are five different reasons why your apartment may be subjected to a dangerous attack.

Incorrectly adjusted heater

There is a certain difference between the internal and external temperature, which is called the dew point. The higher the humidity, the higher the temperature at which water will condense. And if the room is not strong enough to heat the air to dry, the humidity will not go anywhere. Or you will have to constantly air that will lead to additional heat consumption. A person will freeze in vain, and condensate will accumulate already at +12 degrees outside the window.

There is another interesting observation. Those who seek to save money by lowering the temperature in the room at night do not always win. The apartment sometimes cools so much that in order to warm it up it takes more heat than it would have spent normally.

Improper airing

The second main cause of condensate is improper airing. You can not always keep the window on the airing, but to neglect this process is not worth it. The meaning of airing is that the air must be replaced. Sometimes it is better to open the windows a few minutes wide open than not to cover a small opening for hours. And better a few short windings than one long.

Ned change of air masses

Houseplants, thick curtains and blinds can look great on the windows, but prevent normal air circulation. Opening the window you lose degrees, but almost do not get clean air from the street. It is in places that do not fall under the general airing of the room that moisture accumulates and mold develops.

Old windows

The problem of poor ventilation is most acute in old buildings. Those that have double frames in the zone of special danger. Indeed, in the space between the glass air does not circulate at all. In addition, in such buildings very thin glass, which can not provide the necessary insulation. There is a little trick. A moisture-absorbing absorbent is placed in the space between the windows, which is changed as often as possible.

Incorrectly adjusted double-glazed windows

On the one hand, modern plastic windows help reduce energy consumption and reduce heat loss. On the other hand, the room can become almost airtight. Air exchange between the house and the street practically does not occur, as if you are in a submarine. Be sure to choose a suitable ventilation mode. You can use modern split-systems in the apartment, which will ensure the correct ventilation mode.

Low air humidity can also harm your health. Dry air leads to inflammation of the mucous membranes and a decrease in resistance to infections. You can buy a special moisture meter, or buy a humidifier, in which this device will be built. There are industrial air dryers ... But more often you can just ventilate the room and add a couple of degrees on the radiator.
