Do you have this?

Small droplets of water forming tear streams flowing on the windowsill is familiar? Unnecessary puddles cause not only aesthetic discomfort to moisture contributes to the appearance and spread of mold and fungus in the apartment, which affect the health of residents not in the best way

Particularly attentive owners, probably, noticed that the windows are not always sweating, but only with a certain set of circumstances. For example, drops appear in the cold season or only in the morning. Often you can notice an unexpected phenomenon of the window crying in only one room, while in others this is not observed. Or the window is dry, and the water on the windowsill is still present. So what is the reason for such a common problem? Why do plastic windows at home sweat?

We recall physics

Perhaps each of us is familiar with such a concept as condensate is the transition of water contained in the air from a gaseous state to liquid. And the tears of plastic windows are nothing but this condensate. The answer to the question why plastic windows sweat in winter is simple. The main reason for the appearance of condensate is high humidity in the room and the temperature difference in the house and beyond.

If the windows fog partially and not always, then the reason, most likely, is in another. Let's find out what factors provoke fogging of double -glazed windows?

Windows sweat what to do?

Often, we ourselves, not wanting it, create favorable conditions for condensate. Plastic windows sweat in the presence of a large number of colors on the windowsill. Many, placing pots with flowers, completely forget that the plants also breathe, which means they secrete moisture settling on the window. Remove flowers from the windowsill and drops as it happened.

Poor ventilation is another reason for the appearance of streams and puddles. The clogged ventilation grids do not cope with their work, which provokes an increase in humidity and the occurrence of the effect of crying windows. Clean the lattices or replace them, and also make sure if ventilation has closed.

In winter, plastic windows sweat due to the fact that the windowsill blocks the battery. A wide windowsill isolates warm air as a result of the double -glazed window cools and accumulates condensate. It is necessary to ensure free circulation of air to the heater to the window or reduce the width of the window sill.

Insufficient ventilation provoking factor, which should not be ignored. The tightness, the valuable quality of plastic windows, high sealing, can include negative sealing and becomes the cause of window tears. Ventify the room 3 times a day for 3 minutes and the problem will be solved by itself.

Marriage or fruits of frugality?

If all of the above points are taken into account, and the windows still sweat, then you may have fallen as a victim of your own frugality. So a single -chamber double -glazed window acquired in order to save, causes the formation of condensate in 100% of cases. The exit here is one replacement of the double -glazed window. Pay attention to the double -glazed window, not the window!

Unscrupulous installation work, poorly performed internal and external slopes lead to blowing and cooling of the glass. In this case, the slopes should be embedded: the external ones are insulated with foam, and the places of contact of the window and the opening are isolated by cement. For thermal insulation of internal slopes, foam is not suitable, the optimal option for glass wool or basalt plate.

Production marriage is an unpleasant reason, which will not be possible to eliminate without unnecessary costs. The defective window will have to replace this will require financial investments, but will save not only from fogging, but also from other problems that will arise in the future.

It is important to note that the guilt of installers and manufacturers is only 5%, so before blaming third parties, exclude your own omissions and errors.

Take care of heat, but do not forget to ventilate

As you can see, there are plenty of reasons for fogging of plastic windows. Meanwhile, experts argue that most often condensate appears for two reasons due to heat loss and poor operation of the ventilations. This is worth stopping in more detail.

You can prevent the loss of precious heat with the following methods:

to insulate the walls from the inside, so you will transfer the dew point (a place where cold air meets with a warm indoor) to the inner surface of the walls, which will help to some extent improve the situation;
external insulation is more effective. It will allow you to transfer the dew point to the outer edge of the wall and forget about condensate forever;
sometimes the installation of an additional radiator is effective, and even better a complete replacement of old batteries, because New materials carry out heat much better. If funds allow, you can safe and purchase an electric fireplace or a warm floor system;

the autonomous heating system is the right way to make the house warmer, but perhaps this is not always, and you will have to run around the housing authorities. So decide for yourself is the game of candles or not.

Now about ventilation. What needs to be done first?

make sure that the kitchen hood and ventilation grilles in the bathroom are cleaned and in good condition;
check if the neighbors were walled up on top of the ventilation pipe. Do not be surprised, this often happens to take possession of extra square meters leads to the fact that some (contrary to the arguments of the mind) cut or even walled up a ventilation shaft;
in old houses with large attics, the ventilation canal is often clogged with poplar fluff and foliage of trees. If the ventilations have not been cleaned for a long time, then apply with such a request to the organization’s house serving your house;

install forced ventilation in the bathroom and in the kitchen, for example, a fan built into the grate;
remember that metal -plastic windows do not imply natural air circulation, unlike traditional wooden brothers, so do not forget to ventilate the room.

Quite often, double -glazed windows with double and winter operations are installed. But many people forget to change the regime in accordance with the coming time of the year. A window in summer mode to provide proper clamping sash to the profile is not able to. As a result, drafts, ice and condensate ... and tiring searches for a solution to the problem, which is actually easier to eliminate.

Now you know why condensate appears and how to make the windows not sweat, which means that puddles on the windowsill will no longer bother you, they stayed in the past!
