With their appearance, plastic windows very quickly replaced the use of old wooden frames. Initially, only wealthy people could afford to install such products. Now they have become available to almost every class of the population. Plastic windows have gained their popularity due to many advantages. They do not need to be insulated before the onset of cold weather, painted every year. They also perfectly protect against dust getting into the house. They look quite presentable. However, many people have encountered such a problem - plastic windows sweat. If you find the sources of droplets, you can find ways to solve this problem.
The problem of internal fogging of plastic windows
There are cases when condensation appears not on the outside, but inside the glass. The culprit is considered to be a defective glass unit. That is, the manufacturer is to blame. It was he who made a non-hermetic glass unit.
The problem is easy to fix. You will need to replace the glass unit. Installation takes just a few minutes. Moreover, this procedure must be carried out by a specialist from the company that did the installation. The contract necessarily provides for a guarantee, so you will not have to pay for the replacement of a low-quality product.
When plastic windows fog up incessantly, the culprit is the installation of a single-chamber glass unit. Experts say that it is undesirable to use them for housing, because they do not retain heat well. The small gap between the glasses is to blame. It is better to spend more money, but buy a quality product.Plastic windows in the apartment sweat: why and what to do?

Reasons for fogging of plastic windows and ways to get rid of this problem
The problem of internal fogging of plastic windows
There are cases when condensation appears not outside, but inside the glass. The culprit for this is considered to be a faulty glass unit. That is, the manufacturer is to blame. It was he who made the non-sealed double-glazed window.
It's easy to fix the problem. The glass unit will need to be replaced. Installation takes just a few minutes. Moreover, this procedure should be carried out by a specialist from the company that did the installation. The contract necessarily provides for a guarantee, so you won’t have to pay to replace a low-quality product.
When plastic windows constantly sweat, the fault is the installation of single-chamber double-glazed windows. Experts say that it is undesirable to use them for housing, because they do not retain heat well. The reason for this is the small gap between the glasses.It's better to spend more money but buy a quality product. Moreover, their service life is long - several decades.
There are many reasons why a product sweats from the inside. The following reasons can be identified:
Presence of high air humidity indoors.
- Impaired air circulation. If it is too cold in winter and the radiator is slightly warm, then the windows are not able to warm up to the required degree.
- A wide window sill can help block heat flow to the window area. Or the presence of protective grilles on radiators, which, when heat spreads, block its access to the double-glazed window. This will cause condensation to appear.
Poor ventilation. If it does not work, the extraction of moist air will stop.
- Finishing work. During apartment renovations (pasting wallpaper, laying ceramic tiles), a considerable amount of moisture is released. It is this that will settle on the glass.
- Gross violation of compliance with installation technology. The gap between the window opening and the profile may not be properly sealed. Or incorrect tide setting. It must not be screwed, but installed using cement mortar.
- Distortion of window sashes, use of low-quality components.
- Poor quality insulation of slopes: indoors or outdoors. To insulate slopes from the outside, the best option is polystyrene foam or cement mortar. For internal slopes, glass wool or basalt slab is suitable.
The use of a low-quality seal will result in the formation of a gap between the window frame and the glass unit. Therefore, cold air will enter there. The result is condensation.
As you can see, there are many sources of fogging of plastic windows. However, it will not be possible to eliminate this problem without finding the cause.
- We are fighting against “crying” windows
- Initially, you need to find out the source of condensation. Then start eliminating it. If the glass sweats due to ventilation problems, then it can be easily solved. Its performance must be determined. A candle or lighter will be your assistant. You need to place one of these objects in front of the ventilation hole. If the flame does not move, then the ventilation is not working. Will need cleaning. Sometimes it will be enough to remove the grate and wash it to remove accumulated grease and dust.
- In the kitchen, it is recommended to install a hood above the stove. When cooking food, steam is released. It rises and settles on the glass in the form of water droplets. A fan is suitable instead of a hood. This also applies to the bathroom.

- If the problem of glass fogging is the window sill, it should be trimmed. It will not be possible to trim, then you need to move the heating source.
- Solving the problem regarding slopes must begin with determining the material from which they are made. It is advisable to replace putty and plaster with plasterboard. This material has higher thermal insulation qualities. Thanks to this, you can prevent cold from entering the room.
Another important point is the change of “summer” - “winter” modes. Failure to carry out this procedure in a timely manner will result in glass fogging. The fittings can be adjusted independently. In winter, you need to increase the pressing force of the metal plate. In summer - relax.
When it is not possible to solve the problem of “crying” glass on your own, it turns out that the source of drop formation is errors in the production of the double-glazed window or its installation. Then you will have to seek help from an experienced master.
