Windows sweat in winter: reasons, what to do?

With the advent of winter, many owners of plastic windows are faced with a fairly common problem - condensation appears on the glass surface. Most are limited only to the fact that they regularly wipe the windows with a rag. Someone even uses various aerosols that prevent dew drops from forming. But is this the way out? Why do windows sweat in winter? What are the reasons and how to fix it?

This is exactly what we are going to talk about next. I would also like to note that the Teplo Doma company is engaged in solving any kind of problems associated with plastic windows: and so on. If you have no time to delve into all these processes, then just contact our online consultant who will explain what and how to do.

The main causes of sweating

Are you tired of constantly wiping your windows from moisture, and you have a firm intention to sort everything out? In this case, you can proceed.

Why do windows sweat in winter? There are a number of reasons for this:

• Poor ventilation in the room.
• Wide window sill overlapping glass heating.
• Lots of indoor plants.
• Wet weather outside.
• The room is not ventilated.
• Repair work going on.
• Bad heating.
• Etc.

However, all these reasons are nothing when the very essence of why plastic windows sweat in winter is not clear. Of course, each of these reasons has a right to exist. But they all lead to the same thing.

Dew point

Yes, the “dew point” is to blame. What is it all about? In simple terms, the dew point is the temperature at which the air is cooled, followed by the release of the moisture contained in it in the form of condensate. That is, if the windows in the apartment sweat in winter, it means that the window temperature is close to the “dew point”. All this is difficult as long as there is no sign in front of your eyes. It clearly shows under what conditions the windows will start to fog up.

So, what do we understand from the presented table? The fact that wooden windows sweat in winter is influenced by three components: ambient temperature, relative humidity, and surface temperature(in our case glass temperature). If you control all these indicators, then you will never encounter fogging.

Leakage of interpanel seams

There is another common reason why windows in an apartment sweat in winter. And her name is . The fact is that all joints and seams must be waterproofed. But in reality, not all companies do such work when installing a plastic window. As a result, water gets into the cracks that remain after installation. Then it is absorbed into the insulation, which is in the window panel, and from there it falls in the form of condensate onto the window. By the way, the insulation is able to absorb up to 200 liters of water. So it’s not worth being surprised that the windows sweat.

Do you want to get rid of this scourge? Contact the masters of the company "Teplo Doma". They will inspect your window with a thermal imager, find the places where the interpanel seams are leaking and seal them up.

Windows in the apartment sweat in winter: what to do?

Many people think that fogging of windows is due to improper installation or operation of a plastic window. Of course, this is not true. Moreover, if plastic windows sweat a lot in winter, it means that they are fully functional.

So what to do, how to get rid of this problem? Try to control the three components mentioned above.

If the plastic construction provides, then the inside of the double-glazed window does not receive the necessary heating. As a result, its temperature drops, and this, as you understand, leads to the appearance of condensate. It is worth reducing the size of the window sill and the problem is likely to be solved.

It also happens that blackout curtains interfere with air circulation, as a result, everything ends with condensate. Replace the curtains or open them more often, and you will be happy.

Many people like to be indoors multicolor. It seems to some that this way the air will be better saturated with oxygen. However, everyone forgets that plants, in addition to oxygen, release a lot of moisture. Add to this pets and other residents. As a result, the air is oversaturated with moisture, which falls on the windows in the form of condensate. Of course, you won’t get rid of the tenants, but you can distribute the plants evenly across the rooms.

Why do plastic windows still sweat in the winter in the apartment? because of poor ventilation and ventilation. The air in the room stagnates, does not circulate. As a result, it is saturated with moisture, which turns into condensate. Try to open a window and ventilate. Yes, start the cold, but the house will be fresh and no moisture. You can also look in the direction of forced ventilation. It will also help you get rid of problems.

If you started repair, then humidity in the room cannot be avoided. All you can do is to ventilate and dry the air well.

Why do windows in a private house sweat in winter? It may be due to the wrong heating system? Radiators must be located under the windows. So warm air will heat the surface of the double-glazed window, and will also serve as a cut-off for cold air trying to penetrate from the street.

There is one good way to get rid of excess moisture. This is possible with a dehumidifier. Of course, this device is not cheap, but it does an excellent job with its functions.

What can be done to prevent windows from sweating in winter? Approach the solution of this problem comprehensively. The fact is that there may be more than one reason, so you have to carefully figure everything out.

Important! If condensation forms on the windows from the inside, look for a problem in the room: temperature, humidity, and so on. The metal-plastic construction has nothing to do with it.
