When the repair in the apartment is completed, it seems that nothing can interfere with your peace of mind. But there is one, extremely unpleasant moment: during periods of cold weather, condensation appears on plastic windows. Many people think that this is quite normal and, in principle, an expected phenomenon, but in reality it is not so.
Why does condensation form on plastic windows?
The reasons for the appearance of condensation on plastic windows are different, so you need to follow when and how it appears.
There are three types of reasons, conditionally they can be divided as follows:
- Manufacturer and installer errors.
- Placement of radiators and a wide window sill.
- General air humidity.
Most often, ordinary consumers are faced with a low-quality manufacturer who saves on materials. In such cases, the result of fraud makes itself felt in the first winter. Due to the fact that the production process was somewhat disturbed, a so-called decrease in heat transfer appears, which, as a result, has an unpleasant result in the form of condensation on plastic windows.
There is a second reason - the error in the installation of glass blocks. In this case, it was the workers who made the miscalculations. Incorrect measurements and application polyurethane foam, installation of a wide window sill (at the request of the customer himself) - all this can also lead to condensation on the plastic windows from the side of the room.
There is a third reason - high humidity in the living room.
How to get rid of condensation on double-glazed windows?
1. Many people know that if the cause is not eliminated, then you can get a dangerous fungus and mold. To get around these difficulties, this case you need to use a fan that can balance the temperature. If you set a moderate intensity of the fan rotation, then in a few hours the condensate on PVC windows will disappear. Thus, you normalize the air temperature in the room.
2. If this method seems ineffective to you, then you can apply another method. Its essence is to improve ventilation. It is usually enough to check the entire ventilation system, which is quite often clogged.
3. Airing is the simplest and easiest way, which people believe optimal solution question. So you can eliminate condensation on plastic windows from the side of the room quickly enough, but the procedure should be repeated daily. So you will reach the temperature at which condensation will not appear.
Remember, so that this problem does not affect you, you should initially order plastic windows from trusted manufacturers, and the installation of double-glazed windows should only be trusted by professional craftsmen.
Condensation on windows- an unpleasant thing, it is dampness in the apartment and puddles on the windowsills. If you want to get rid of condensation and freezing of glass, you should use these tips. When they stand very coldy, the windows in the apartments freeze quite strongly, this an unpleasant surprise especially for those who have installed plastic windows. If glass is an excellent heat insulator, then metal is no less good conductor heat. Freezing of glass takes place exactly along the perimeter of the window. The resulting condensate flows onto the windowsill and slopes, from which numerous puddles and stains form. Even despite the fact that PVC windows are not afraid of water, this phenomenon is extremely unpleasant. How to get rid of condensation?
First of all, you need to understand the cause of freezing. This happens because the temperature plastic windows lower than the “dew point” in the apartment, steam condenses on the glass, because it does not warm up. When windows are replaced with plastic or wooden double-glazed windows, the window deepens considerably. The frame with a double-glazed window is generally 90-120 millimeters wide, although the wall thickness is 50-70 centimeters. As a result, the glass turns out to be inaccessible to the convection jet of warm air from the radiator, so that an unventilated zone appears in the window sill area.
Many housewives who grow flowers on window sills, when replacing windows with plastic counterparts, try to make wider window sills so that they protrude another 5-10 centimeters. This still half blocks the convection flow from the radiator, and, accordingly, the ventilation worsens. And the abundance of flowers on the windowsill does not affect the situation very favorably. Condensation on plastic windows This is the result of poor ventilation.
A problem such as condensation can be avoided by making sure that the glass does not cool so much. If you only plan to replace windows with double-glazed windows, you should give preference to the thickest possible frame profile in order to reduce penetration. Of course, a couple of centimeters of the window sill will have to be sacrificed, but condensation on windows will bypass you. In addition, it is advisable to order not a double (the most popular), but a triple-glazed window, or a double-glazed window with additional glass. Such a double-glazed window is not only a guarantee of excellent sound insulation, but also that the windows will not freeze through even at a temperature of minus 35 degrees.
You should not try to expand the window sill, pots with plants will fit on the standard one, but ventilation from radiators will help to avoid problems with “weeping” windows. If you are already facing a problem like condensation on plastic windows, nothing remains but to establish air exchange in the window niche.
How to get rid of condensation on plastic windows
- One of the most simple ways prevention of condensation is a burning candle. To do this, in severe frosts, a pair of candlesticks with thick, slowly burning candles are placed near the window. When burning, a warm air flow is created, warming the glass, and a romantic mood in the apartment will not hurt.
- If there are practically no plants on your windowsill, but the option with candles causes dislike, you can try to build convection screens. These are plates of small width that will direct warm air from the battery to the window. You need to fix such a plate at an angle of 30-60 degrees. So that they do not stand out, you can disguise them under the sides of the window sill or a decorative element.
- The easiest way to create airflow in a niche is with fans. It is enough to turn it on at low intensity so that it captures several windows. Can also be used homemade fans with micromotors and wings made of thick cardboard and tin.
- Some people prefer to solve the problem with chemistry. To do this, just go to the auto cosmetics store and purchase anti-fogging aerosols. Glasses must be washed and dried before being treated with them. The glass will stop fogging up like this, but only for certain time, so this method cannot be called a cardinal solution to the problem. Besides, Chemical substance for cars - no the best option for residential premises.
- Some craftsmen manage to turn the windows in their own apartment into heated ones. To do this, a foil, conductive film or nichrome thread is glued around the perimeter of the window, and a small voltage of 24 volts is applied to it. The part of the window that freezes the most will be warmed up, this technique also works in cars.
There is an opinion that if plastic windows sweat, then this is necessarily due to their improper installation. In fact, this is just one of the possible reasons why condensation occurs on the windows.
Location of the condensate
If condensation appears indoors, the problem must be solved in a timely manner so that mold and fungus do not appear. The most important thing is to determine the location of the condensate. If it appeared inside a double-glazed window, then it refers exclusively to a manufacturing defect. In this case, you should call the company that was engaged in the production and installation of windows and ask to replace the double-glazed window under warranty. As a rule, the guarantee for the tightness of double-glazed windows is given for a period of five years.
But if condensation appears on the surface of the glass inside the room, then window manufacturers will not be able to help in this situation. The problem of condensation on double-glazed windows indoors should be given timely attention. so that such serious problems as moistening of slopes and walls, the appearance of mold do not develop.
To get rid of condensation on the windows, you need to understand the reasons for which it occurs. By the way, don't a large number of condensate is allowed by international standards.
Why plastic windows sweat from the inside
The process of glass fogging is associated with the transition of water from a gaseous state to liquid state. The warm air in the room contains water in the form of steam. The warmer the air in a room, the more moisture it contains. The source of such moisture can be both the people themselves, pets, and plants, pots with liquids, washing, cleaning, cooking processes.
When moist air cools, the vapor turns into water droplets. Physics has a name for this process - condensation. Misting due to condensation will occur when the air in the room comes into contact with glass, the temperature of which will be below the dew point. The dew point is the temperature at which vapor from air turns into liquid. Glass in the room always has the lowest temperature, it is for this reason that fogging occurs on the surface of plastic windows.
What to do if plastic windows sweat or how to remove condensate
There is different ways, which will help reduce the amount of condensate collected on the windows of the living space. The most common are a decrease in air humidity, as well as an increase in the temperature of the glass itself.
high humidity air occurs in case of improper organization of the inflow fresh air into the room and the lack of a properly working exhaust ventilation. the main task ventilation is the removal of air saturated with vapors from the room.
Ensuring natural ventilation of the room
To ensure natural ventilation, it is necessary to ventilate the room 4-5 times a day. If modern plastic windows are installed in the apartment, then the tightness of such double-glazed windows is 100%. Therefore, the habitual air exchange in the room for years is changing dramatically. Now the owner must take care of the flow of fresh air into the apartment himself: ventilate the room, use the window ventilation mode. It is recommended to ventilate the room up to four times a day for five minutes with the door open.
Good ventilation system: exhaust
Often bad job hoods lead to fogging of plastic windows, especially in the kitchen. All attempts to maintain normal air humidity will be nullified if the hood is not working. remember, that ventilation grates must always be clean. If the ventilation does not perform its functions, you should contact special services that will help eliminate the blockage.
Ventilation grilles are usually located in the kitchen and bathrooms, in order to ensure normal ventilation in the rooms, you need to choose the right one interior doors. They must have overflow holes (grids) at the bottom of the web. Or the gaps between the floor and the door should be left up to 15-20 mm.
Glass temperature rise
The window sill should not cover the radiator at all, this will significantly increase the temperature of the glass To provide optimal temperature glass and minimize the risk of condensation on the windows, you should choose the correct width of the window sills. The window sill should not completely block the heating radiators. The flow of warm air should be able to rise up, warming the glass. If the window sills are wide, you need to think about inserting ventilation grilles into them.
Blinds and roller blinds should not be attached to plastic windows too close to the glass, because they also interfere with the heating of the glass from the heat of the radiators. plays an important role in glass temperature correct installation the glass panes themselves. Double glazing experts advise choosing with a larger system width. Assembly seam along the perimeter of the installation of double-glazed windows should not be blown.
The coldest part of the window is its bottom. Poet, the appearance of condensate is most often noted precisely in the lower part of the window.
Knowing possible reasons why plastic windows sweat, it will be quite simple to eliminate the formation of condensate in the apartment with your own efforts. Whether there are good windows in your apartment, and whether the manufacturer is the cause of the condensation, will indicate the place of fogging.

Plastic windows perfectly fulfill their function: they perfectly retain heat, isolate street noise and keep the temperature in the room. But a frequent occurrence is the appearance of condensate on the glass in the cold season. Why do plastic windows sweat in winter and how to fix such a problem?
Causes and consequences of fogging windows
The cause of fogging windows is hidden in physical properties water. Being in a gaseous state, it is imperceptible, but when the temperature drops, the so-called dew point is reached, that is, water vapor passes into a liquid. It is in this case that condensation forms, which settles on plastic windows.
The cause of moisture settling on the glass is high humidity. If the windows began to fog up from the inside, there can be only one reason - this is a defective double-glazed window. This element of the entire system must be sealed, and if this condition is violated, water vapor enters, where it settles on the inner glass when cooled. This problem is eliminated by replacing the double-glazed window, the frame can be left.
However, most often condensation forms on the outer surface of the window. Why do plastic windows sweat in winter and how to eliminate such a factor? There can be several answers to this question:
Subsequently, fogging leads not only to a violation of the view through the glass. Often this process provokes the occurrence of worse phenomena:
- Freezing windows and the formation of frost on them.
- High humidity is the cause of mold, rot and fungus.
- Water and low temperatures gradually destroy the foam in the gap and break the tightness of the entire system and the house.
Constant fogging of windows can lead to mold growth What to do with such negative influence And how to eliminate the causes of fogging windows?
Troubleshooting
If your windows are leaking, you need to establish the cause of the phenomenon. It happens that the situation arises as a result of placing a large amount on the windowsill indoor plants, which evaporate a large amount of moisture.
Window adjustment
You can make sure what is the cause by making a simple inspection of the entire window. The first thing to do is to check the correct adjustment of the flaps and the degree of their locking.. This is done in the following way:
- You can feel a strong draft by running your hand along the window.
- Set fire to a match or candle, if the light fluctuates, then the tightness is broken.
- Paper is placed in the sash and locked. You can pull out the sheet without any effort.
If deficiencies are found, proceed with the adjustment. The sash is set vertically and horizontally with screws located on bottom loop.
To adjust the sashes, tighten the bolts located on the bottom hinge The degree of pressing is regulated by eccentrics at the ends of the window, as well as by tightening the pressure plates.
Transfer to winter or summer mode carried out with the help of eccentrics Do not forget about the seasonal adjustment of windows. To do this, the regulators turn the marker inward for the summer, and towards the street in the winter.
window sills
Often windows cry due to improper air circulation during the cold season. The reason lies in wide window sills, which block the access of warm air masses to the surface of the double-glazed window.
In this case, to normalize the circulation in the window sill, you need to drill several holes that will ensure normal access of heat to the glass.
Holes in the window sill allow warm air heat glass You also need to pay attention to the grilles covering the heating radiators, perhaps they also interfere with air exchange.
slope finishing
If the window was installed with violations of technology (leaky gaps, the frame has moved), then you should contact the installer. Installers are obliged to fix such a problem free of charge.
An independent attempt to seal the gaps may not correct the situation, since the double-glazed window was initially installed incorrectly.
Finishing and insulation of slopes prevents fogging of windows Another thing is with slopes. If finishing has not been done, it must be carried out immediately, otherwise it will lead to total destruction mounting foam in the gaps. In order for the windows not to cry, it is best to additionally insulate them using heat-insulating material (mineral wool, polystyrene or foam plastic).
accessories
Quite often, windows cry due to poor-quality or worn fittings. All mechanisms must function normally and smoothly lock the sash with normal pressure.
Damaged seal must be replaced The seal must be carefully inspected. It should be elastic, without tears and cracks. If there is damage, and elasticity is lost, proceed to replace it.
Ventilation
The ventilation of the room must be approached very carefully. This is especially true for rooms with increased level humidity (kitchens, bathrooms), where windows sweat most often in winter.
After all, plastic windows completely seal the room and make it difficult for air to enter from the street. You can solve the problem of air exchange in the following ways.
Check existing ventilation for blockages. This can be done by lighting a candle near the channel exits. If the light does not deviate, then the hood does not work. The grids are removed and cleaned until normal functioning is restored.
However, apart from exhaust system ventilation must also be present. This issue is resolved by setting ventilation valves on the windows.
Forced ventilation can be provided with a valve built into the handle Today there are modern supply systems installed in the window handle, they do not spoil the appearance and provide a sufficient amount of fresh air.
With the provision of a normal level of ventilation, the problem of high humidity is also eliminated..
thermal insulation
Single-chamber double-glazed windows are used in most non-residential premises, where thermal insulation is not so important. If such a double-glazed window is installed in the living room, then it will not provide proper heat conservation.
Thermal insulation of glass with film will not solve the problem of cold You can fix the problem by insulating the slopes and applying an energy-saving film to the glass. But these measures will not ensure the preservation of heat in full.
Humidity level optimization
As mentioned above, this phenomenon can be eliminated by ensuring the normal ventilation of the rooms. However, if this does not help, then you can mount dehumidifiers under the windowsill. Such cartridges are inexpensive, and their efficiency is quite high..
Recent renovations can contribute to the increase in humidity in the room. Big square plastered surfaces evaporates a huge amount of moisture, which ventilation cannot cope with. This is a temporary phenomenon and as the walls dry, the humidity level returns to normal.
As a rule, these are the main reasons that windows cry in winter. When they are eliminated, the situation will normalize and there will be no problems with fogging.
You installed new plastic windows in your house, but after a while, a problem arose: did moisture begin to form inside the double-glazed window? With a similar problem, the Teplo Doma company is often asked for help. That is why solving it is not a novelty for us.
But there is one here important point: windows fog up from the inside, not from the outside. Is there a difference? Of course, these are two completely different problems. Accordingly, they require a different approach.
If condensation is ON double-glazed windows
When condensation forms on outside double-glazed windows, most likely, the culprit is the one who operates the metal-plastic structure. You can solve this problem on their own. If you do not have time to look for reasons, then you can seek help from our specialists, and they will already help.
It's important to know! When the liquid overcomes the dew point, it turns into water droplets on your windows. As a result, the windows fog up. And if it’s very cold outside, and the double-glazed window is single-chamber, then this very water on the windows turns into ice.
Condensation between double-glazed windows is not only unaesthetic, but also dangerous. If the windows are constantly wet, then an ideal environment will be created on their surface for the development of various kinds of bacteria and fungi. And this, in turn, can seriously affect the health of residents.
Why is there condensation on double-glazed windows? There are actually several reasons:
- Increased indoor humidity.
- The window sill covers the battery.
- There is poor ventilation in the room.
- Lots of indoor plants.
- Windows not translated to winter mode.
- The room is poorly ventilated.
- Installation errors.
- Conducting indoors repair work.
- Leakage interpanel seams(let's explain: when the seams leak, moisture finds its way to the insulation, is absorbed into it and then evaporates into the room).
- And etc.
All these reasons contribute to the formation of condensate on the double-glazed window. As a result, we are faced with such a problem as fungus, mold, bacteria and a complete lack of appearance our metal-plastic structures.
Now, it should have become clear to you that the cause of the appearance of condensate can be completely eliminated on your own. If for some reason you are unable to do this, then contact the specialists of the Teplo Doma company for help. By the way, one of them is ready to discuss the solution to your problem right now.
Your attention is presented a table by which you can determine the temperature at which condensate will fall in any case. In order to solve the problem, the following values \u200b\u200bare required: relative humidity and air temperature.
If condensation is INSIDE the double-glazed window
When condensation forms on a double-glazed window, consider yourself lucky. Why is that? The fact is that moisture can also accumulate inside the window. Now this is a more serious problem. In the first case, you can solve it on your own, and in the second it will not work. And all because if there is condensate in double-glazed windows, there can be only one reason here - depressurization.
But why did this happen? In most cases, the manufacturer is the culprit. plastic window. The design could not be made in accordance with GOST, as a result, during operation, the window was depressurized, and moisture got inside.
For your information: initially there is specially dried air
What does it threaten? The window stops working. It lets in the noise from the street, the cold. A humid environment is formed inside it, and this is a breeding ground for fungi and bacteria. You can't see anything through this window.
How to remove condensation between the panes in a double-glazed window? It is unlikely that you will be able to deal with the problem on your own. That is why the most right decision will be - the call of the master.
If condensation on a double-glazed window with inside, then in most cases the matter ends with the replacement of the double-glazed window itself. It's easier, and the price is almost the same as repair metal-plastic construction. The specialists of the Teplo Doma company will select the most optimal solution for you.
Condensation inside a double-glazed window: what to do, video?
Representatives of the Teplo Doma company prepared a video on this occasion, in which the problem of depressurization of double-glazed windows is discussed. If you want to eliminate the condensate inside the double-glazed window, then this video will be useful for viewing.
Master's call
Alas, the problem of depressurization of double-glazed windows is not far-fetched. It leads to the fact that people are wondering why condensate collects inside the double-glazed window. The Teplo Doma company carries out repair of plastic windows in Moscow and the region. The specialists of our company know their work and are able to help you in resolving any difficult situation related to the breakdown of metal-plastic structures.
