If it blows from plastic windows, what should I do? Many people face a similar problem. They begin to feel the cold air currents that come from the plastic windows. Although it is believed that PVC windows are distinguished by their tightness and should not allow air to pass through, however, such a problem exists. This becomes especially noticeable in the cold season, when the temperature regime in the apartment is of particular importance, since it becomes cold outside and heat inside the room is necessary.
What to do?
If it blows from plastic windows, what should I do? If the windows were installed a short time ago, then you should contact the organization that provided installation services. As a rule, companies that provide such services give guarantees to their customers. Therefore, if the warranty period has not yet expired, it is recommended to contact the company that installed the windows. Then its employees must eliminate the shortcomings in the work.
In the case when there is no guarantee for windows or it has ended, you can find out the reason for blowing from plastic windows on your own. Or contact a specialized company that repairs window systems.
In order to make a choice, repair the windows yourself or contact the company, you should understand the reason. If it is insignificant, then you can independently get rid of the problem of blowing window systems.
Where does the air flow?
Before talking about why it can blow out of plastic windows, it is worth determining where the windows let air through. To do this, you will need tools such as a candle or a regular lighter. With the help of these items, you should determine from which places the air passes through the window.
There are certain safety rules that should be observed when working with fire. Firstly, you do not need to bring a candle or a lighter close to the plastic. This is due to the fact that plastic can begin to deform under the influence of fire. Secondly, a person must ensure his safety when working with fire. Namely, avoid contact between the flame and the skin. When testing the passage of air through plastic windows, you need to run your hand along the frame and feel the air flow. Particular attention should be paid to the joints of the frame with slopes and window sills. In addition, you need to check if air is passing through where the window fasteners and hinges are located.
Causes
Why is it blowing from plastic windows? What to do? Note that there are several main causes of the problem. We list them below. So, why is it blowing through plastic windows (what to do, you will soon find out)?
- The window may not be properly adjusted. In this case, air enters the room through the sash. As a rule, there are two types of window adjustment: summer and winter. If the window is adjusted in the summer mode, then in cold weather cold air will enter the apartment or house, thereby causing discomfort to the residents of the house or apartment.
- Marriage. If it blows from the slopes of plastic windows, what should I do? Another reason may be a marriage that was made in production. It includes a poorly made profile, namely a violation in the reinforcement process. In addition, there may be damage to the double-glazed window. The plastic itself may be of poor quality. That is, the material does not meet the required standards. In this case, the plastic may not withstand the temperature difference in regions with a harsh climate.
- The reason for the passage of air may be poor fittings. Therefore, it is recommended to choose high-quality fittings in order to avoid problems with windows in the future. Insulation also affects the quality of use, it is also not worth saving on it.
- Of particular importance is the installation of the window. The installation must be carried out by professional technicians with experience. Since a violation of the design can lead to the fact that the windows will blow.
- The number of double-glazed windows affects the quality of the window. It is determined by the climatic features of the region. The colder the climate, the more double-glazed windows should be installed.
You should know that the complete absence of air passage through plastic windows is also not very good. Since in this case a greenhouse effect may occur. Air circulation must be present. If it is not there, then the windows will begin to flow. Therefore, professional window adjustment is necessary. We will tell about it further.
How to adjust plastic windows?
As mentioned above, there are two modes for adjusting plastic windows, namely summer and winter options. The first option assumes the presence of a micro-ventilation mode in the adjustment. This is necessary so that a favorable microclimate is present in the room. The winter version involves a snug fit of the window sash to the frame. Thus, the air flow into the room is reduced.
If it is revealed that air enters the room along the entire perimeter of the sash, then this means that the mode should be changed from winter to summer. In order to carry out this process on your own, you should understand how the window design is made. Clamps are located along the entire perimeter of the window. They provide a tight fit of the sash to the window frame.
Switching between modes
In order to ensure a tighter fit of the sash to the frame in winter, turn the internal clamping mechanism as far as possible to the right in a clockwise direction.
For summer mode, this procedure should be carried out in the opposite direction. The important point is that all internal clamping mechanisms are adjusted equally. If this action is violated, then perhaps the window frame will break. It should be said that if there are doubts about the correctness of the implementation of these actions on your own, then it is better to turn to professionals.
You should also be aware that there is an automatic window transition from summer to winter mode and vice versa. In this case, the mode is brought by the manufacturers to the fittings. Thus, switching the window to the desired mode is not difficult.
Hinge area
If it is blowing from plastic windows, what should I do when it comes from the hinge area? If it has been found that cold air is coming from the hinge area, then this mechanism should be examined. The fact is that there are several elements that can cause this problem.
So what to do if it blows from the hinges of plastic windows? What to do in this case? The most common reason for the passage of air in this area is the presence of mosquito net attachment elements on the outside. In this case, the sealing process should be carried out. Then the cold air will stop flowing into the room.
Also, the reason for the entry of cold air into the room is fittings that do not meet quality standards. Or the installation of the window was carried out poorly. If the reason for the penetration of cold air into the room is unfair installation, then you should call a specialist. It will adjust the fittings and eliminate the source of cold air entering the room.
In the case when the fittings do not meet the quality standards, it is necessary to change it. It is better not to initially save on this parameter, but to buy a window with high quality fittings.
Blowing from under the window sill
We figured out why it is blowing from under the plastic windows. What to do if it blows from the windowsill area? If during the inspection it was revealed that cold air flows come from below, from the area where the window sill is located, then this may mean that there is no sealing. When installing the window, the distance between the lower frame and the window sill is filled with mounting foam. If air is blowing, then there are holes.
What to do if it blows from below the plastic window, what to do? It is recommended to putty the foam in order to avoid exposure to the external environment. You can fix poor-quality installation yourself with a sealant. If he did not give the desired results, you should remove the window sill and fix the flaws from the inside.
Finally
Now you know why plastic windows are blowing and what to do in this case. We hope that this information was useful to you.
Everyone understands how important it is to keep warm in your home with the onset of cold weather. Heating today is an expensive pleasure, so spending heat right and left is extremely unreasonable. As you know, the main heat loss of the house occurs through windows and doors. So far, we are only interested in windows. Of course, heat loss cannot be completely avoided, but it can be reduced. In addition, if it also blows from the window, then by eliminating this problem, you can significantly save on heating.
And why blows windows at all? The popularity of this problem is growing exponentially with the onset of winter. We are often approached with this kind of trouble. But we know what to do with all this. Do you want to be in the know too? In this case, start studying this issue right now. However, we still recommend that you first contact a Teplo Doma specialist.
Blows plastic windows: reasons
Before sounding the alarm, you need to understand everything. Do pvc windows really blow through? Maybe it's just too cold outside, and the frame and double-glazed windows are too thin? If so, then there is little good here. The installers made a mistake and installed plastic windows that were not suitable for the temperature regime. That is why it is better to immediately contact trusted and reliable companies.
If it really blows through plastic windows, then here are the main reasons:
- Broken window structure. The window should be returned to the manufacturer, of course, if it is under warranty.
- Mounting errors. Unscrupulous installers quite often make mistakes during the installation of plastic windows. Subsequently, these errors result in a pretty penny for the owner. If it blows from the slopes or from under the windowsill, then these are definitely installation errors. You should contact the company that performed the work and ask to redo everything.
- Incorrect adjustment. If the window blows from the side of the hinges, then this is most likely due to incorrect or untimely adjustment. The window sash needs to be adjusted twice a year. If this is not done, then over time it will close loosely. As a result, questions arise why plastic windows are blown. Also, the windows may not initially be correctly adjusted. In this case, it blows from the window from the first day of installation, but it only becomes noticeable with the onset of cold weather.
- Violation of window geometry. This is more related to improper installation.
- accessories. In order not to blow out of the window, you should regularly maintain the window structure: adjustment, lubrication. If the fittings jam, the window cannot be closed tightly, as a result, the owners will face the problem of blowing.
- sealant. If the plastic windows of the hinge are blown through, then a poor-quality seal may be the culprit. Also, the sealing gum can become unusable over time. If this element has lost its properties, it should be replaced, otherwise blowing cannot be avoided.
- Violation of the integrity of the frames. Window frames of modern windows, as a rule, are made of plastic. However, this plastic is not always of the highest quality. Plastic can be slick from the scorching summer sun, and then become extremely brittle with the first frost. If a crack goes along the frame, then it will definitely start blowing out of the window.
In fact, more could be said about the reasons. There are many, sometimes even extremely ridiculous situations in which the owners find themselves because of their gullibility to unscrupulous craftsmen.
You need to order the installation and repair of plastic windows only in a reliable company that has been tested not only by time, but also by people.
Blows out the window: what to do?
So, you are faced with the problem of blowing. What's next? The easiest way is to call us. It really is the best option. We will send a specialist who will assess the situation and quickly fix everything. Why do you need extra hassle?
Do you firmly believe that you can do it on your own? In this case, you will first have to determine the cause of the blowing, and then eliminate it.
The most innocuous case is when it blows from the windows, because they are not translated into . Probably, you have never heard that plastic windows have winter and summer regimes. So, if all the pins on the end of the sash are turned to the desired position, the window will begin to press against the frame much more tightly. As a result, the draft will disappear.
If it blows through the window from below, then it is worth taking a closer look at the window sill, or rather, how it is installed. According to the correct cavity under the window sill should be filled with mounting foam, and plaster is applied on top. Draft from under the window can be tried to eliminate with a sealant. If it doesn't work out, the window sill will have to be reinstalled.
If it blows through a plastic window from the side of the hinges, then, as already mentioned, a good adjustment is required here.
They blow windows in a new building at the junction of the frame and impost, this is most likely a manufacturer's defect. You should call the company that did the installation and ask for the windows to be replaced.
If the cause of blowing was a dried seal, then it should be lubricated with artificial petroleum jelly. Did not help? .
Blowing between the window sill and the adjacent frame will be more difficult to cure. In most cases, dismantling of the structure will be required.
When blowing was found between the wall and the frame, then again, poor-quality installation was to blame. How to eliminate? You can try to seal the seams, but the best result can only be achieved if the window structure is reinstalled.
The specialists of our company have filmed an excellent material for you - “Plastic windows are blown: what to do, video”. After watching this video, you will know exactly why it is blowing from the window.
A fairly common problem that appears in a huge number of people who live in private houses and apartments is blowing from a plastic window.
Very often modern plastic windows have a “sin”. But the manufacturer assures that they are all sealed and of high quality. The question is, why is this happening? And also because of what a draft is formed from a plastic window?
Causes
Experts identify several reasons that are capable of blowing.
These include:
- Industrial marriages;
- The use of low-quality plastic, which deforms over time and can even burst at different temperatures.
- . If it is of poor quality or heavily contaminated, the tightness decreases, micro-slits appear through which air can pass.
A bad effect on the quality of windows occurs due to improper storage of metal and plastic things in the open air or in rooms where there is no heating. As a result, the quality of the installation also deteriorates, which then contributes to the occurrence of blowing.
One of the most common causes of a problem with plastic windows is poor-quality fittings.
Therefore, never no need to save money on buying and installing windows. It also blows from PVC windows due to incorrect incorrect adjustment, which does not allow the sashes to fit well to the surface.

Blowing from the side of the loops
Blowing in this place occurs due to incomplete filling of the mounting hole. To get rid of this problem, take a good look at the sashes and close them tightly.
In addition, the cause of the draft may lie in the technological gap for attaching mosquito nets or other additional holes, which are located on the outside of the window.
If a draft forms from under the handle of plastic windows, this indicates that they have lost their functions in full force.
The sash does not completely begin to cling to the base, as a result, a small gap is formed through which air can pass.
Blowing between the window sill and the plastic window
The most basic reason in this case is a poorly installed window.
During installation, the master used little mounting foam, while the short one is "responsible" for reliable and correct fixation in the opening.
Blowout Elimination
To properly troubleshoot, it is important to clearly understand the cause of the purge.
If the air passes around the entire perimeter of the sash, then the window has not been switched to winter time, that is, the fittings do not fit snugly against the frame. The system needs to be regulated.
To do this, the pins, which are located along the perimeter of the wings, must be simultaneously transferred to the maximum position (move clockwise). Of the tools you will need a screwdriver or pliers.
This kind of operation must be carried out with the window open. The main thing is to find and turn all the trunnions, because the structure may break.
Some window manufacturers do this process automatically - the fittings are equipped with a roller with special rings. It rotates itself and easily changes the mode from winter to summer.
Other reasons that provoke blowing, can be removed like this:
- If the siphon is from below from under the windowsill - the reason is in the installation (not airtight).
- The space under it needs to be foamed, and then plastered.
- To prevent the wind from blowing, use a sealant. You may also need to reinstall the window sill.
Briefly about the installation of a window sill in a draft:
- It is necessary to insulate and seal the window sill with mounting foam.
- If the slopes are through, this means that the assembly seam is destroyed. Mounting foam in slopes functions for 5-10 years. To fix the problem, it is necessary to disassemble the slopes, and re-seal the frame with foam.
- If it comes through from the junction of the frame and the impost of the window structure, this indicates a defective product. The gap must be sealed with sealant.
- If it blows from the hinges, you need to look at the sash and close it tightly.
- If the seal has dried up and become inelastic, blowing also appears here. This problem can be solved by replacing the seal. This operation can be easily done by yourself. The main thing is to choose the right seal.
How to seal plastic windows so as not to blow
There are situations when all the ways to fix blowing problems are not effective and do not give any results.
This means that you need to fix this problem in other ways. One of them is the insulation of a plastic window for the winter.
First you need to improve the slopes. It's actually possible to do this using:
- Styrofoam;
- Styrofoam;
- mineral wool;
- Sandwich panels;
- Fiberglass.
Choose a material based on the size of the cracks. Glue the material with mounting glue, then putty and paint.
There is also an option to seal the cracks in the plastic window. For this, ordinary adhesive tape or self-adhesive sealant made of rubber or foam rubber is suitable.
But this should be done when a strong draft remains after all the above criteria have been corrected. Plastic windows are practical and easy to use, but there are problems with them, which lead to certain troubles. A special moment when the windows were installed incorrectly and not adjusted correctly.
To avoid such problems, order plastic windows only from trusted manufacturers, and trust installation only to specialists in their field.
How to choose plastic windows is written.
Winter time gives not only a lot of positive emotions and holidays, but also a lot of troubles. One of them is that they begin to let cold air and drafts into the room, thereby chilling the rooms.
To solve this problem, you first need to find out why and where it blows from the plastic window. At first glance, it seems that it is quite easy to find out the cause of this trouble, but this is not so, because in the case of plastic windows, the range of possible causes is very large.
We identify the causes of blowing.
First you need to find out whether it is actually blowing from the window opening. The fact is, no matter how paradoxical it may sound, but often it can only be an illusion, for example, if you have a not very warm window, then at sub-zero temperatures, cold air circulates not from the street, but from the home side (inside). The glass cools down, which just makes us think that the window lets in the cold.
To understand does the plastic window let the cold through, use this method - bring a burning candle close to the sash in the place where it comes into contact with the window frame. If you see that the fire began to fluctuate strongly, then it definitely blows from the windows, and if the flame is direct, then this indicates a good sealing of the window structure - then the reason lies elsewhere.
A candle must pass around the perimeter of the structure and then you will determine exactly where the problem areas are. More often, cold comes from those places where the window frame joins the slopes, it is here that the most vulnerable places are located. The reason for this is poor-quality installation, and it blows from the slots located in the slopes or under the windowsill. If the window warranty has not yet expired, then it is best to contact the company that installed the window for help and demand that they solve this problem. They will definitely respond and send a master to you, who will have to completely eliminate the mistakes made.
How else can you determine why it is blowing from a plastic window? There are a lot of answers to this question. The most common cause becomes. You can deal with such a problem quickly and easily. The window structure must be correctly in its rightful place. True, these works are still better to entrust to a professional.
It often happens that during the installation of the window, a violation of the geometry of the window structure was allowed, because of this, the sashes do not fit well to the frame, which causes drafts.
In this situation, nothing can be adjusted, here it will be necessary to reinstall the equipment in the opening, taking into account all the previously made mistakes.
Next the most common cause of drafts it may become more often this is done underground in China or in Turkey. Of course, such accessories are much cheaper, but its quality will correspond to such a price. Therefore, you need to buy and order the installation only in trusted companies.
The next reason for the appearance of cold can be, which, under the influence of sub-zero temperatures loses elasticity. Moreover, not only the poor quality of the sealant can cause drafts, but also its contamination. In this case, you need to replace it. Of course, not everyone will be able to cope with such work, so it is better to entrust it to professionals.
Moreover, today many companies offer modified seals that have better performance and a longer service life. Very often drafts can be caused poor quality plastic which is made from cheap raw materials. Such plastic differs from the good one in that ultraviolet rays and high temperatures, with prolonged exposure, begin to destroy it, as a result, in the autumn and winter, cracks often appear on the window structure. Such a profile is no longer subject to repair.
As you can see, there can be a lot of reasons for the appearance of drafts and cold from PVC windows and they are all different, but the biggest number of problems lies in the poor quality of the window construction. That is why it is better not to save on, as this can result in additional large cash costs that one might not have to face.
But if you want to have reliable, durable and high-quality windows in your house that will reliably protect the room from cold and drafts, then you should seek help from a well-known company in the city, and they, in turn, will do everything possible to order to
Metal-plastic windows differ from products made from similar materials in reliability and. But even new designs can have a common defect - the lack of complete tightness. The first sign of a similar problem is that it starts to blow out of the plastic windows. What should an ordinary person do in this case? You can try to fix the defect yourself.
Hardware adjustment
After installing the plastic window, the primary adjustment of the fittings system is performed. The same procedure is done after 2-3 months, when the structure finally takes its position in the opening. The frequency of adjustment in the future is every six months.
If this is not done, the sash will change its position relative to the frame. The consequence is that the overlap will decrease and microcracks will appear. They are the main reason why the windows blow. For adjustment, it is recommended to invite the master or try to do it yourself. This will require a 4mm hexagon.
The overlap is 8 mm. Adjustment can be done in the following ways:
- Lower (upper loop) and tilt-and-turn scissors. These elements have hexagonal holes. They allow you to change the position of the sash in a vertical plane or in height. The exact adjustment instruction depends on the type of fittings.
- With the help of pins. They provide a tight clamping of the sash. In some systems, the trunnions are in the form of an irregular cylinder. By turning them on the pin, you can improve the clamping of the transom.
After these steps, it is necessary to check the tightness of the closure. This will require a thin sheet of paper. It is inserted between the sash and the frame, the first is closed. The paper must be pulled out with effort.
Slope insulation
Another source of drafts are poor quality slopes. Their final arrangement is carried out after 3-5 days from the moment of installation of plastic windows. If you do not provide sufficient tightness, the slopes will cause heat loss.
Obvious signs are the appearance of mold and dampness on the wall. To solve this problem, you need to take the following actions:
- Dismantle the slopes up to the mounting foam.
- Treat the wall with antifungal agents.
- Install butyl rubber tape to prevent moisture.
- Install a protective and decorative layer as a base: plaster, sandwich or similar materials.
After that, the problem should be resolved. If it continues to blow from the side of the window, there are other sources of draft.
Seal replacement
To ensure tightness, seals are mounted in special grooves at the ends of the sashes and frames. Their average service life is 3 years. After that, the material begins to lose its properties - plasticity decreases, after pressing it does not acquire its previous shape. The latter is the cause of drafts.
The solution is to install a new sealing seal circuit. But in this case, the following nuances must be taken into account:
- For each type of profile, a special type of seal is used. The difference is the configuration in the section. It is recommended to consult with the company that installed plastic windows.
- In some profile types, the sealing contour is soldered into the profile. Its replacement is impossible or involves the use of complex technologies.
- For self-installation of the sealing circuit, a special roller is required. With its help, the rubber is fixed in the groove.
It is important that the new sealing contour does not interfere with the normal closing of the leaf. Additionally, you can adjust the fittings - the transom clamp.
We determine the factory marriage and installation errors
The most difficult case is non-compliance with the manufacturing technology of plastic windows or mistakes made during their installation. This is determined in the first days after installation. But clear signs appear with the onset of cold weather, when the difference between the temperature in the street and in the room increases.
A list of common window structure defects that arose through the fault of the manufacturer or installers:
- Poor quality seam between profiles. From microcracks can blow.
- Loose fit of the double-glazed window to the rubber seal.
- The absence of a layer of sealant between the Mauerlat and the frame.
- Slots in the connecting profile connecting the two structures.
Such defects must be repaired under warranty. If it has expired, you can isolate the place of penetration of street air with the help of special sealants. With a large volume - alteration of the window or order a new one. About, .
The video explains in detail what to do to independently adjust the window sash and eliminate drafts:
