Blowing from plastic windows: reasons, what to do? How to adjust plastic windows yourself What to do if it blows

Many believe that replacing old windows with wooden frames gets rid of all problems.

But when the cold comes, many notice some shortcomings in the system. Is it possible to get rid of them? And why is this happening?

Blowing plastic windows: about the main reasons

The reasons for blowing through windows fall into three categories.

  • Mistakes made during installation.
  • Hardware or low quality plastic.
  • The presence of a manufacturing defect.

You can describe the reasons in more detail.

  1. The occurrence of gaps in the window sill due to improper installation.
  2. Installation of slopes of poor quality, lack of insulation.
  3. If the integrity of the frame structure is broken. Plastic with low cost usually does not withstand even minimal loads.
  4. The seal is very dirty, its poor quality.
  5. Bad hardware. It is never advised to save on it.
  6. Failure to comply with the rules during installation, because of which the geometry was violated.
  7. Loose fit of the sash due to incorrect adjustment.

Elimination of the causes of blowing

Are drafts noticeable throughout the entire perimeter? Perhaps the mode has not been changed to winter. This happens, for example, due to a loose fit of the frame.

Which, in turn, arises from poor quality fittings. Adjustment in such systems is indispensable.

Several trunnions are simultaneously brought to the maximum position, which are located along the perimeter of the valves. Ordinary pliers and a screwdriver are enough to solve this problem.

During the operation, the window must be opened. The design will break if you do not turn and open all the trunnions at once.

Many manufacturers even at the factory set automatic transitions to one mode from another. For this, a roller is placed inside, equipped with a special ring. When rotated, it changes modes from one to another.

There are other ways to fix existing problems.


"False blowing"

“Chill” from a double-glazed window and blowing are different concepts, but many people confuse them with each other. Blowing is a significant defect, which cannot be said about the chill. The latter can manifest itself in two ways.

The decrease in the temperature of double-glazed windows occurs in winter due to the weather outside the window. When the air in the room comes into contact with the lower point of the sash, it also cools.

Sliding occurs on glass surfaces, only from top to bottom. Substituting the palm under the sash, we feel the effect of a slight blowing. The tightness remains the same, but there is a feeling that cold air is blowing.

This effect is due to several reasons. For example, a battery that does not work exactly according to the instructions.

Chilling occurs due to drafts or ventilation with high power. Owners of ordinary double-glazed windows with one chamber also fall into the risk group.

Sealants and putties to reduce heat loss

The method of fastening on glazing beads is considered the most reliable. If it blows from under the glazing beads, they can be insulated with the help of sealants.

Silicone sealant or special putty will add to the effectiveness of this solution. You will need a construction gun to use a tube of sealant.

The composition is applied on top if the glass is not planned to be removed. The composition fills the holes on the wings and cracks, joints of glazing beads and glass. But the surface must be dry and clean. A knife is used to clean the place from excess sealants.

Everyone can prepare putty on their own.

So-called seals are made from several materials.

  • Rubber.
  • Polyurethane.
  • Polyethylene.

In the market you can often find products made of rubber. Self-adhesive options deliver the least problems in operation.

After the purchase, it remains to remove the protective film, and then attach it to the frame. These are more reliable options, because they are well fixed on the surface.

Silicone rubber - optimal solution. Temperature and humidity do not lead to defects.

Universal profiles are marked with the letters D or B. On the window sash, the material is fixed around the perimeter. The main thing is not to stretch it during work.

When it starts to blow from plastic windows, this is always bad news for the owners. Especially when this problem manifests itself in the cold season, because it is urgently necessary to solve it. In winter, the appearance of drafts is not only discomfort, but also a direct road to a hospital bed.

Of course, the window needs to be repaired, but first you need to decide on the causes of the draft. In fact, finding these very reasons is not so easy. Sometimes, only an experienced specialist can do it.

If you don’t really want to delve into this issue, you can order from Teplo Doma. After us, your house will literally be warm.

How to find the problem area?

If it blows through plastic windows, then you can find the place of blowing on your own. To do this, we need a candle or a match. It is known that it is easy to determine the direction of the wind from the flame. So, if you move the flame around the entire perimeter of the window, then you can understand whether it is blowing from it at all or not, and if it blows, then where is the gap.

It happens that it seems to the owners that in the cold season it starts to blow from the window. However, this is just an illusion. In fact, they just have thin windows installed. When it's cold outside such windows freeze through. As a result, circulation occurs indoors. This process can be mistaken for a draft.

Why is it blowing from a plastic window: reasons?

When the problem area is identified, you can start thinking. What to think about? On our own repair the damage or still call the master. This is a very important question. Of course, when the design is under warranty, you can safely call the company that installed the plastic windows. However, if one no longer exists, or the windows were bought separately, and the installation was carried out by some kind of “stray” team, in this case, you will have to turn to third-party specialists for help.

Yes, maybe you managed to find a problematic place, but this does not mean at all that the cause has been established. If all this looks complicated for you, then it's time to contact a specialist from Teplo Doma. An online consultant is just waiting for you.

So, there are a number of reasons why it blows from plastic windows. How to fix the problem is what matters.

Adjustment is to blame

Quite often, the fault of the fact that a draft appeared from the window is wrong or done at the wrong time. Firstly, setting up window fittings must be done correctly initially. Secondly, every year all window elements need to be tightened so they don't get flustered. If these conditions are not met, then a draft is guaranteed.

How to adjust plastic windows so as not to blow? It is impossible to write a clear guide to action here. The fact is that windows are different, and they are always installed in different ways. When setting up accessories, remember:

  • The window sash must fit snugly against the frame.
  • Nothing should hang out.
  • The window should close and open smoothly.
  • The window should close and open easily.
  • Nothing, nowhere and nothing should cling.

All of the above problems can be obtained with just one incorrect setting of the fittings.

How to tighten plastic windows so as not to blow? Same as setting up. It is important to make sure that the adjustment is to blame for everything.

Installers made a mistake

It’s rather sad to hear the verdict of an experienced window specialist: “Well, the fact is that ... The installers made a mistake, you need to redo it.” Of course, it’s sad, because because of someone’s negligence, a plastic window blows from under the window sill or slopes come through. Now, repairs are needed, and it costs money. And it’s good if everything can be repaired, otherwise dismantling and subsequent installation “in a new way” may well shine.

If the masters made mistakes in the calculations when installing the metal-plastic structure, and as a result it blows from under the window sill of the plastic window, then you can contact the company that performed the installation. If the company is serious and values ​​​​its reputation, it will definitely respond and fix the problem.

Sometimes due to improper installation, the geometry of the window structure is violated. This is why it blows. Of course, you can try to adjust the plastic window, but in such situations, such manipulations do not always help.

The seal does not seal

If the window seal ceases to perform its functions, then this is noticeable immediately. Blowing from a plastic window, how to eliminate the cause? If the seal is to blame, then it is very simple: him.

The sealing gum may be defective, may dry out over time, may crack due to lack of regular maintenance, may become dirty. In fact, the seal quite often fails. And if the plastic window blows from the side of the hinges, then it is far from a fact that the wrong adjustment is to blame, although this is logical. It is possible that the sealing gum has become unusable, and the formation of the problem began just from the side of the loops.

Window profile failed

This happens quite rarely, but still not without it. Sometimes manufacturers, in pursuit of low cost, produce plastic windows. As a result, after a while, such plastic begins to crack under the influence of ultraviolet rays and temperature changes. Someone blows the hinges of a plastic window, someone under the windowsill, someone from above or below. Immediately, the wrong adjustment comes to mind as reasons, and then the sealant that has become unusable. However, when it becomes clear that neither one nor the other is the cause of the draft, you have to look elsewhere. And in the end, it turns out that the problem was in the profile.

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 reasons for blowing on your own, but immediately invite a representative of a construction company to eliminate the deficiencies. 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.

The main reasons why it blows from plastic windows

It is not necessary to immediately assume that the problem is due to a design defect or incorrectly carried out 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:

  • incorrect adjustment - blowing from the sash of a plastic window due to the fact that it has not been switched from summer to winter mode;
  • manufacturing defect - poor-quality reinforcement of the profile, the double-glazed window is damaged, cheap plastic was used, which may not withstand the temperature difference;
  • low-quality fittings and sealant are those parts of double-glazed windows that you never need to save on, so choose the most reliable fittings;
  • unprofessional installation - incorrect installation, no insulation of slopes, the window sill is not installed correctly, the geometry of the structure is broken;
  • the number of double-glazed windows does not match your climate zone.

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.

How to adjust a plastic window so that it does not blow?

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:

  • Winter mode, when you want to ensure the tightest possible fit. To do this, all pins along the perimeter of the wings are moved clockwise to the farthest position so that the longest possible radius is directed towards the room when the frame is closed.
  • Summer mode, when window eccentrics turn to the shortest radius towards your room. In this position, there is a minimally dense porch: air freely enters through the sashes and the room is constantly ventilated.

Important! Before starting work, find all the trunnions to turn them at the same time, otherwise the window metal plastic construction 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.

Blowing from the side of the loops

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 window

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 window sill

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 in order for the foam, under the influence external factors, did not collapse and new pockets of drafts did 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.

Blows between the frame and slopes, 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 in the summer overhaul slopes, 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.

Duo of rubber bands

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.

How to seal plastic windows so as not to blow?

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:

  • single-chamber double-glazed window installed;
  • the number of double-glazed windows is insufficient for your climate zone;
  • heating does not work well;
  • heating radiators are blocked by an overly wide window sill;
  • too much ventilation is installed.

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.

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:

  1. Industrial marriages;
  2. The use of low-quality plastic, which deforms over time and can even burst at different temperatures.
  3. . If it is of poor quality or heavily contaminated, the tightness decreases, micro-slits appear through which air can pass.

The bad effect on the quality of the windows is due to improper storage 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 fastening mosquito nets or other additional holes that 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, short "responsible" for a 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 transferred to winter time, i.e. the hardware does 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.

Such an operation should be carried out open window. 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:

  1. It is necessary to insulate and seal the window sill with mounting foam.
  2. If the slopes see through, it means that it is destroyed mounting seam. Mounting foam in slopes operates 5-10 years. To fix the problem, it is necessary to disassemble the slopes, and re-seal the frame with foam.
  3. 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.
  4. If it blows from the hinges, you need to look at the sash and close it tightly.
  5. 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.

Probably, it is not necessary to say that plastic windows are required to ensure complete sealing of the window space. That is, they are entrusted with the functions of protection against noise, cold, dust and drafts. Quite often, people turn to Teplo Doma with the question - “Why is the window blowing from the side of the hinges?” So that's exactly what we would like to answer in this article. There can be several reasons for this disease:

  • Incorrect installation.
  • Poor adjustment of the window sash.
  • Failed fittings.
  • Worn-out sealant.

As a result of all this, it blows from the side of the hinges, between the frame and the window, and also under the window sill.

Reason #1

If it blows from the hinges, then the first thing to do is to inspect the fittings and sashes. To do this, you need to remove the window glazing beads and get to the plastic straightening plates. The glazing beads can be removed with a special flat spatula. It just needs to be driven into the seam and the glazing bead will fall behind the window. If the straightening plates have shifted, they should be returned to their place. In the event of a breakdown, a replacement will be required.

Sometimes the air penetrates into the room through the holes from the window fasteners. At this moment, it seems that it is blowing from the hinges of plastic windows. Inspect the sash, find the holes and fill them with sealant. The problem should be gone.

If you have any difficulties, please contact our online consultant. He will tell you how best to act in a given situation.

Reason #2

In most cases, it blows from the plastic window on the hinge side due to incorrect adjustment. In order not to encounter such problems, you should initially order the maintenance of metal-plastic structures in a reliable company.

If it starts to blow from the bottom hinge, then most likely the window needs to be adjusted vertically. When blowing from the upper hinge of a plastic window, horizontal alignment is needed. Is it blowing through the entire side? Try adjusting the sash pressure. This event is also called "". Window trunnions located on the end of the sash will help to achieve what you want.

In order to carry out the desired work, you will need a hex key and a WD 40 type tool. Each window hinge has two bolts. The side bolts are responsible for moving the sash vertically, and the upper bolts horizontally.

Important! Before proceeding with the adjustment, coat all fittings well with WD 40.

When the window is adjusted correctly, it is unlikely to see through from under the hinges.

Reason #3

If the plastic window blows from the side of the hinges in the middle, then the old dry sealant may be the reason for this. When the elastic loses its elasticity, it no longer fits snugly to the frame. As a result, gaps form between the sash and the frame. But why is it blowing from the hinges of plastic windows? The fact is that on the opposite side the clamp is carried out by a window handle. As a result, the entire window is pressed, and on the side of the hinges, the seal does not reach the frame. It begins to seep through the cracks, and the homeowners feel discomfort. Fixing the problem is easy. You just need to buy a new sealing gum and replace it.

Important! Sometimes regular lubrication helps to reanimate an old seal. You can use artificial Vaseline.

The next reason may be some element of fittings. Quite often, window manufacturers save on fittings, as a result, soon after the purchase and installation, the owners have problems with the operation of metal-plastic structures. If the fittings are out of order, the problematic element should be replaced.

Is it blowing from the side of the window sash hinges? Who did the window installation? Are you sure that everything was done according to the rules? Maybe the installation of the window was initially carried out incorrectly? If there is a skew and the absence of a perpendicular, then it blows from under the upper hinge of the plastic window quite legally.
