Among the main factors causing the appearance of drafts are:
Before proceeding with the elimination of cold air from the window opening, it is more expedient to find a problematic place, as well as to understand the real reason for its appearance.
At an external temperature of -20 degrees, a plastic structure with a low heat transfer rate tends to cool strongly, therefore, the air from this window will also be cold. When such air circulates in the room, a feeling of draft is created.
To determine the exact location of the blow, you can use the following method:
Slight fluctuations in the tongue of the flame indicate normal air circulation along the glass.
It is also recommended to check the junctions of the plastic system with internal slopes, since it can blow from the gaps in the slopes or from below from under the windowsill. If there is a valid warranty for a plastic product and its service, you must contact a specific company.
Fixing the problem:
Cause: the handle of the plastic window is out of order, as a result of which the sash is loosely pressed against the surface (at least a slight, but a gap is formed).
Solution: either adjust, or clamp all fasteners, or replace with a new one.
For this:
Cause: installation of a window block with obvious violations, in particular, an insufficient amount of mounting foam.
Solution:
If you feel a slight blowing in this area, you can seal the seam with silicone sealant.
If the situation has not changed after all the above actions, the window must be reinstalled.
Cause: the expiration date of the mounting foam has expired, it has completely collapsed and lets cold air through.
Solution:
The most common cause of drafts in the room is considered to be improperly adjusted mechanisms of the plastic structure.
Setting rules:
With the inscriptions GO and ROTO, the setting of the metal tongue is made under the handle. To do this, the tongue must be pressed and directed parallel to the seal.
The cold has come and many of us are puzzled by the question - blowing from plastic windows, what to do? Moreover, the manufacturers promised tightness, reliability and minimal heat loss of the structure. There can be many factors leading to this problem.
However, first you need to analyze why cold air is formed at the window. Maybe it's mixing air due to temperature difference? An ordinary candle can help with this - it is set on fire and rushes along the perimeter of the sash - judging by the flame of the candle, they conclude in which place it comes through.
They also pay attention to junction of the window frame with slopes- if the installation of the slopes was carried out illiterately or they are not sufficiently insulated, then it can blow out of the slots (not only in the slopes, but also in the window sill). If you just installed a plastic window and it is still under warranty, then you should call the wizard to fix installation defects, but if the warranty period has passed, you will have to deal with the defects yourself.
Broadly speaking, the reasons may be the following:
Much depends on the correct adjustment of fittings.
If you are interested in solving the question: why is it blowing from plastic windows and what to do, then you should first find out the reason for this phenomenon.
So, if a draft occurs around the entire perimeter of the sash, then your window is probably not switched to winter mode- so the fittings do not ensure sufficient fit of the sash to the frame. In this case, the existing system needs to be adjusted. To do this, the trunnions located along the perimeter of the wings are simultaneously transferred to the maximum position (you need to move them clockwise) - for this you need a screwdriver or pliers.
Important: The operation is carried out with the window open. It is necessary to find and turn all the trunnions, otherwise the structure will break.
Some window manufacturers have made the transition process automatic - the fittings are equipped with a roller with a special ring. It rotates and easily changes modes from winter to summer.
Other causes of drafts are eliminated in this way:

If you do not want to face such a nuisance as drafts from plastic windows, then you can take additional measures at the stage of choosing and installing a window. These include the choice of high-quality window construction - durable and reliable PVC profile, durable fittings. It is clear that it is worth purchasing a product only from well-established companies that have long been known in this market segment.
You will also need to monitor the quality of window installation. In addition, do not forget that really good specialists provide a warranty service, during which you can eliminate all detected defects without your own investments and labor.
We pass the seams with sealant It is also important to follow the rules for the operation of metal-plastic windows, monitor the condition of the seal, lubricate fittings in time, and so on. You can also take steps to insulate the space under the window sill before a problem occurs - for this you need a sealant. He neatly applied along the seam between the wall and the plastic structure. In addition, be sure to protect the mounting foam from the harmful effects of moisture. Vapor barrier film and silicone are well suited for these purposes - thanks to them, the wall will be reliably protected from mold, as well as from the appearance of fungi. If you follow the simplest rules for the operation of PVC windows and fix all the problems that have arisen in time (with the involvement of specialists or on your own), then the problem of blowing plastic windows will not arise. You will be able to enjoy the warmth without unpleasant cold air from the street, even on the windiest and frostiest days.
In this section, in continuation of our article, we suggest you watch a useful video. The video shows a way to eliminate blowing from window slopes.
Manufacturers of plastic windows claim that their double-glazed windows cannot be compared with wooden "Soviet" windows. Plastic windows and sounds from the street do not let through, and you can forget about drafts with them. But it happens that promises remain promises - through the windows both the barrel and continues to blow.
The cause of drafts is not in the design of double-glazed windows. It's all about the technology of their installation. If the technology for the production of plastic windows is European, then the method of installing them remained Russian. The windows are simply “planted” on polyurethane mounting foam, through which both noise from the street and drafts pass perfectly.
If you critically consider the result of the work of window installers, you can easily notice the shortcomings due to which double-glazed windows do not perform their functions well. Usually, installers save on mounting foam - use it in insufficient quantities, leave space unfilled with foam, etc.
In addition to the negligence of the installers, there is another reason why the windows are blown by all the winds. The fact is that polyurethane foam in itself is not an ideal insulating material. Under the influence of temperature changes, humidity, solar radiation, it gradually collapses and loses its operational properties.
However, among the reasons for blowing, there may be a manufacturing defect of the window. A perfectly reasonable reason may be improperly sealed slopes.
The first thing you need to pay attention to is the condition of the mounting seam. Wait for cool windy weather outside and run your wet palm along the seam. In the place where the window lets air in, you will feel a clear chill. In such places it is necessary to carry out additional thermal insulation. Gaps and voids in the mounting foam must be filled with a new portion of the foam.
If the cause of the draft lies in the wear of the seal, it should be replaced with a new one. To do this, you will have to remove the double-glazed window, remove the old gum and stick a new one in its place. It happens that it blows from plastic windows due to the skewing of the shutters. In such cases, it is recommended to adjust the fittings and the clamping mechanism.
If none of the methods described above helps, and it is still blowing from the plastic windows, you can act drastically by ordering the installation of a new window. You can also hang blinds on the window. They, in addition to their main purpose, cope well with drafts.
Winter is a wonderful time of the year. It brings with it many good holidays and joy. However, it is in winter that a fairly common problem of plastic windows can manifest itself. It's about the draft. In the warm season, the owners rarely pay attention to the fact that it is blowing from the window. In winter, it is impossible not to notice. If a draft in an apartment with plastic windows, then this problem must be solved. Otherwise, the room will not only blow, but the temperature will drop to “uncomfortable”. And here it is not far from diseases.
Yes, the problem, of course, needs to be solved, but you should start by finding out the reasons for its appearance. Everything is more complicated here. It just seems that it is easy to understand why a draft appeared in PVC windows. In fact, there is something to think about here.
In this article, we will talk with you about what can cause a draft from plastic windows. So let's get started.
Before you grab your head and call all the craftsmen in the city, you should make sure that it really comes through the window. It happened that people came to us with a draft problem. However, the master made a diagnosis - thin plastic windows.
Turning to an unknown company for the installation of PVC windows, you take responsibility for almost everything. Yes, it is you, and not the company to which you applied and paid the money.
In one region of our country it can be cold in winter, and in another it is simply cool. Insulated plastic windows are provided for one region, but not for another. A company that performs its work in good faith will always tell its client which metal-plastic structures he needs to install.
So, back to thin plastic windows. In winter, an illusion can be created that it seeps through. But in fact the glass is cooling, and air circulation begins to occur inside the room.
In order to detect a draft, you can use an ordinary candle, match or lighter. It is necessary to move fire around the entire perimeter of the window. If the flame does not sway, then it will not see through anywhere. Accordingly, if it is, then problem areas can be identified.
As a rule, plastic windows let in a draft in two places: between the frame and the sash; between the frame, slopes and window sill. It depends on where it leaks, what kind of repair is needed for the metal-plastic structure.
What is the reason why it shows through between the window frame and the slopes? The installation company made a number of mistakes. If this window is under warranty, then it is better to call this very company and demand that the problem be solved. The fault here is not yours, but the masters who carried out the installation. In the event that the warranty period has ended, you will have to choose: or solve the problem yourself, or seek professional help.
The Teplo Doma company offers its services to eliminate drafts from plastic windows. Our masters very often face similar problems and know everything about it. You can contact a specialist and discuss all the conditions right now.
If, nevertheless, a draft appeared between the sash and the frame, then there may be several reasons.
Incorrect adjustment will always show up. When the window has been adjusted incorrectly, over time it may cease to perform its functions fully. As a result, for no apparent reason, a draft appears in an apartment with PVC windows. It even happens that the fittings were initially adjusted correctly, but regular maintenance was not carried out for several years. As a result, it began to bleed through the window.
How to solve this problem? If the cause of the draft is indeed in improperly configured fittings, then adjustment should be made and the problem will be solved.
When unskilled craftsmen are engaged in window installation, mistakes are often made. For example, the cause of a draft from a window may be a violation of the geometry of the window structure. As a result, the sashes do not adhere well to the window frame, and this, in turn, can cause drafts.
Perhaps the most common cause of drafts from plastic windows is rubber seal problem. It may be old, poor quality or just dirty. When the window seal fails, the sash no longer fits snugly against the frame. As a result, a draft breaks into the room. If for this reason it bleeds through a plastic window: what should I do? Everything is simple here: and the problem will be solved immediately.
Surprisingly, the plastic profile itself, from which the double-glazed window is made, can also cause a draft. Due to temperature changes and exposure to ultraviolet rays, plastic of poor quality may burst. As a result, from the resulting gap will begin to see through. In most cases, repairing such a window does not make any sense. Required here
With the very first autumn colds, you began to notice that the windows let the cold through. Quite a common problem, but your window structures are plastic, characterized by tightness and minimal heat loss, so why is it blowing from plastic windows?
Recently installed windows are still under warranty, so you should not look for the causes of blowing on your own, but immediately invite a representative of a construction company to eliminate the shortcomings. In any case, calling a master is the easiest way, but why spend money if many defects can be fixed on your own?
Let's understand the problem. It is possible that you only need to learn how to tighten the plastic windows so that the wind does not blow, and the discomfort will disappear, but it is likely that much more effort will be required to correct the situation and the services of specialists will still have to be used.
It is not necessary to immediately assume that the problem is due to design defects or improper installation work. Don't get ready for a major renovation until you find a source of cold air. To analyze the situation why it is blowing through plastic windows, an ordinary candle or a lighter will help. With the help of fire, we will look for all possible places for cold air leaks from the street.
Attention! We handle open fire as carefully as possible: do not bring the lighter too close to the plastic so as not to damage it. We run our hand along the entire frame, paying special attention to the places where the window structure comes into contact with the walls and the window sill. Do not forget about the hinges, handle and sealing rubber.
How to adjust a plastic window so that it does not blow
The main reasons for blowing plastic windows:
Note! If it blows from a plastic window, the room is automatically ventilated and the double-glazed windows do not fog up. By eliminating the problem of drafts, you can already have a completely opposite problem. If your plastic windows, do not forget about the prevention of this phenomenon, about which there is a detailed article on our website.
Seasonal adjustment of window structures means changing the summer mode of micro-ventilation to winter, when the sashes fit more tightly. Most often, simply by changing the degree of pressure of the sash, you can completely remove drafts in the house.
If plastic windows blow around the entire perimeter of the sash, how to adjust? First of all, we study the design: clamps are located along the entire perimeter of the PVC product doors, thanks to which a tight fit to the frame is ensured. Clamps are in the form of eccentrics with a recess for a 4 mm hex key.
By simply turning the eccentric, adjustments are made to:
Important! Before starting work, find all the trunnions to turn them at the same time, otherwise the metal-plastic window structure will break.
Please note that for many manufacturers, the transition from summer to winter mode is automatic. In such designs, all fittings are completed with a special mechanism - a roller with a rotating ring, with the help of which the pressure of the sealing gum to the frame is loosened or strengthened.
If it is found that it is blowing from the hinges of plastic windows, what should I do next? It is necessary to continue the inspection and identify all unfilled mounting holes in order to close them later. There are quite a lot of various fastening elements around the loops, passing inside the frame through the plastic itself.
As an example, there may be holes on the outside of the frame for attaching a mosquito net. Air can enter these cavities, which will enter the room through the frame in the hinge area, creating a draft. A simple sealing of the holes quickly solves such a rather serious problem.
Adjustment of fittings of plastic double-glazed windows
The second common reason why it blows from the handle of a plastic window or from the side of the hinges is poor-quality fittings or incorrect installation methods. You can hope that it will be enough just to tighten it, but most often you have to buy new fittings to avoid drafts in the winter.
Blowing from under the bottom indicates exactly that the window sill is not completely sealed. When installing double-glazed windows, the builders had to qualitatively fill the entire space under the window sill with mounting foam, while not saving it.
Important! After filling with mounting foam, it is imperative to plaster the treated space under the window sill. This is done not for beauty, but so that the foam, under the influence of external factors, does not collapse and new pockets of drafts do not appear.
If it blows from the window sill of a plastic window, it will be necessary to seal all the cracks where a draft is felt. You can fix a similar problem on your own, but if the sealing does not remove the blowing, you will need to replace the window sill.
Another similar reason associated with poor-quality installation. So it can be argued if the double-glazed window was installed recently. If the plastic structure is operated for a long time (at least 7-10 years), then it must be understood that over time, the mounting foam always begins to wear out and collapse.
Such a problem does not show up overnight. A good owner will plan a major overhaul of the slopes in the summer, but what can be done with the onset of cold weather? The destruction of the assembly seam can be suspended with the help of sealants, but this is only a temporary measure.
If blowing is found in the place where the frame is in contact with the window sill, we can also talk about negligent builders and saving foam. The frame is attached to the opening with appropriate anchors, then everything is insulated with mounting foam and plaster.
A draft from a plastic window seal (in other words: rubber bands) indicates its partial or complete destruction. Over time, the seal seems to dry out and begin to crack.
You can try to repair small cracks with glue, but still such blowings are removed only by replacing the sealing rubber. The procedure is easy enough to carry out on your own, the main thing is to choose the right sealant for the existing plastic profile.
Remember to take a small piece of old gum with you when you go shopping to make it easier to choose.
Sometimes it seems to you that a double-glazed window is see through, but in fact, it just seems to come from cold. This is most often observed in the lower parts of the valves. This is not blowing at all, since a draft is not detected.
The chill from the windows can be explained by the fact that you have:
It is not difficult to carry out the insulation of a double-glazed window yourself. You will need a special film for insulating plastic windows. To learn how to apply it correctly, review the following recommendations.
