Why is it blowing from plastic windows? What to do? Possible causes and solutions. What to do if blowing from plastic windows Blowing from windows what to do

Everyone understands how important it is to keep warm in their homes with the onset of cold weather. Heating nowadays is an expensive pleasure, therefore it is extremely unreasonable to spend heat to the right and to the left. As you know, the main heat loss at home occurs through windows and doors. So far, we are only interested in windows. Of course, you will not be able to completely avoid heat loss, but you can reduce them. In addition, if it is also blowing from the window, then by eliminating this problem, you can significantly save on heating.

Why does it blow out the 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 specialist of the Teplo Doma company.

Blowing plastic windows: reasons

Before you sound the alarm, you need to understand everything. Does pvc windows really blow out? Maybe it's just too cold outside, and the frame and glass unit 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 precisely why it is better to immediately contact trusted and reliable companies.

If it really blows through plastic windows, then here are the main reasons:

• Defect of window construction... The window should be returned to the manufacturer, of course, if it is under warranty.
• Installation errors... Unscrupulous installers often make mistakes during the installation of plastic windows. Subsequently, these errors result in a pretty penny to 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 it blows through the window from the side of the hinges, then this is most likely due to incorrect or untimely adjustment. The window sash must be adjusted 2 times a year. If this is not done, then over time it will not close tightly. As a result, questions arise as to why plastic windows are blown through. Also, the windows may initially be incorrectly 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 incorrect installation.
• Fittings... In order not to blow from the window, you should regularly carry out maintenance of the window structure: adjustment, lubrication. If the fittings jam, the window will not be able to close tightly, as a result, the owners will face the problem of blowing.

• Sealant... If the hinges are blown through the plastic windows, then the fault may be a poor-quality seal. Also, the sealing gum may deteriorate 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 are usually made of plastic. However, this plastic is not always of the highest quality. Plastic can blur from the scorching summer sun, and then become extremely fragile with the very first frosts. If a crack goes along the frame, then it will definitely blow from the window.

In fact, the reasons could be discussed more. There are a lot of, at times, even extremely ridiculous situations in which the owners find themselves because of their gullibility to unscrupulous craftsmen.

It is necessary to order the installation and repair of plastic windows only in a reliable company, which has been tested not only by time, but also by people.

Blowing out the window: what to do?

So, you are faced with a blowing problem. What's next? The easiest way is to call us. This is really the best option. We will send a specialist who will assess the situation and fix everything quickly. Why do you need extra trouble?

Do you firmly believe you can do it on your own? In this case, you will have to first determine the cause of the blowdown and then eliminate it.

The most harmless case is when it blows from the windows, because they are not transferred to. Probably, you have never heard that plastic windows have winter and summer modes. So, if all the pins at 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. Accordingly, the cavity under the windowsill should be filled with foam, and plaster should be applied on top. You can try to eliminate a draft from under the window using a sealant. If it does not work out, the window sill will have to be reinstalled.

If it blows through the plastic window from the side of the hinges, then, as already mentioned, a good adjustment is required.

They blow out windows in a new building at the junction of the frame and the impost, this is most likely a manufacturer's marriage. Call the company that installed the windows and ask them to replace the windows.

If the cause of blowing is a shriveled seal, then it should be lubricated with artificial petroleum jelly. Did not help? ...

Blowing between the sill and the adjacent frame will be more difficult to cure. In most cases, the dismantling of the structure will be required.

When the blowing was found between the wall and the frame, the fault was again a poor-quality installation. How to fix it? 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 - "blows plastic windows: what to do, video". After watching this video, you will know exactly why it is blowing out of the window.

Among the main factors causing the appearance of drafts are:

1. Manufacturing defects in products. Most often, the use of low-quality raw materials in the production of a plastic system can provoke deformation of the entire structure, and with sudden temperature changes, it will burst altogether. In addition, improper storage of finished windows can also have a negative impact on the product. For example, if metal and plastic profiles are kept for a long time in rooms unprotected from external influences, in the cold, this will also provoke deformation. Ultimately, the quality of the installation will deteriorate, and with it the tightness of the structure will be broken.
2. Low quality fittings and plastic. Considering the importance of the fittings for the entire plastic block (it is responsible for the tight fit of the sashes when closing), there is clearly no point in saving on this. When choosing such mechanisms, it is recommended to give preference to more expensive, high-quality products. It is also worth paying attention to the correctness of the adjustment, as one of the reasons for the appearance of drafts. As for, with its low quality or strong pollution, you can forget about the tightness of the structure: small gaps appear that let the cold air flow through.
3. Installation without adherence to basic standards. Even if the window is made of high-quality material, and the fittings are from the best manufacturers, if installed incorrectly, the plastic structure will not be able to provide adequate comfort in the room. The work should be carried out by experienced craftsmen. Another factor in the occurrence of drafts is considered to be the wrong finish of the window from the inside: installation work with violations, unscrupulous insulation of slopes, incorrect installation of the window sill. The result is gaps that allow cold air to pass through.

How to determine the place of blowing

Before proceeding with the elimination of cold air from the window opening, it is more advisable to find the problem area, 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 draft is created.

To definitely determine the location of the blowing, you can use the following method:

1. Light a candle or use a lighter.
2. Draw it around the entire perimeter of the window.
3. In places where the candle flame will fluctuate strongly and is a problem area.

Slight fluctuations of the flame tongue indicate normal air circulation along the glass.

It is also recommended to check the joints of the plastic system with the inner slopes, since it can blow from the gaps in the slopes or from below from under the windowsill. If there is a valid guarantee for a plastic product and its service, you must contact a specific company.

We fix the problem:

1. Blowing from the hinges

1. Cause: incomplete filling of the mounting holes. Solution: conducting a thorough examination of the valves and closing them tightly.
2. Cause: technological gaps for fixing the mosquito net, external holes. Solution: in winter there is no need to use additional holes, it is more expedient to close them for a while.
3. Cause: poorly installed fittings or poor quality. Solution: completely replace or properly adjust.

2. Blowing from the handle

Cause: the handle of the plastic window is out of order, as a result of which, the sash is not tightly pressed against the surface (a gap is formed, though insignificant).
Solution: either adjust, or tighten all fasteners, or replace with a new one.

For this:

1. Remove the decorative strip that hides the place where the handle is fixed to the window structure (turn the strip 90 degrees and unscrew the fastening screws under it).
2. Detach the old handle and install the new one using the same fasteners. Close with a decorative plate.
3. Make sure the handle is working (if necessary, adjust it).

3. Blowing from under the glazing bead

1. Cause: The seal does not meet the requirements. Solution: replacement with a silicone sealant, its performance has high performance in terms of thermal insulation. For this:
   • Remove the previous rubber gasket;
   • It is good to clean the profile from dirt;
   • Stick on the required seal.
2. Cause: the presence of factory defects on the glazing beads or loose pressing against the window block. Solution: replace with a better one, additionally seal the gaps between the plastic structure and the glass unit with silicone.

4. Blowing between the sill and the window

Cause: installation of a window block with obvious violations, in particular, an insufficient amount of polyurethane foam.

Solution:

1. Remove the window sill from the outside (from the street).
2. Remove old polyurethane foam, if any.
3. Fill the space completely with polyurethane foam.
4. Replace the ebb.

If slight puffing is felt in this area, the seam can be sealed with silicone sealant.

5. Blowing from under the windowsill

1. Cause: improper installation of the window unit. Solution: calling a specialist from the company that installed the plastic block.
2. Cause: the seal has become unusable, errors in the installation of the window sill. Solution: the resulting gap must be sealed with sealant, polyurethane foam (for large gaps) and the window sill must be reinstalled. Replace the failed seal with a new one using a special glue.

If the situation has not changed after all the above steps, the window must be reinstalled.

6. Blowing from the slopes

Cause: the validity period of the polyurethane foam has expired, it has completely collapsed and passes cold air.

Solution:

1. Dismantle the slopes.
2. Foam the existing seams around the entire perimeter of the block.
3. Install slopes.

The most common reason for the appearance of drafts in a room is considered to be improperly adjusted mechanisms of a plastic structure.

Customization rules:

1. Clamp. Its adjustment is carried out from the end of the window, where there are three eccentrics, the so-called pins. Using a hexagon, the trunnions are rotated with moderate movements depending on the situation: for the pressure density - to the left, and to loosen it - to the right.
2. Fittings. Here, all attention is focused on the locking of the window, if there is an AUBI inscription, then the sash is mounted in a vertical position. This means that the metal bar with the spring must be pressed and the handle turned to the correct position.

With the inscriptions GO and ROTO, the adjustment of the metal tongue is made under the handle. To do this, the tongue must be pressed down and directed parallel to the seal.

1. Do not neglect the preparatory work on the insulation of windows in the winter.
2. First of all, the entire plastic block must be thoroughly cleaned of dirt and drainage channels.
3. Periodically inspect hinges, mechanisms, casement plates.
4. When detecting cracks, it is recommended to use high-quality silicone, and the moving accessories must be lubricated with grease, so you can extend its service life.
5. Particular attention should be paid to the seals, in case of accumulation of moisture on the rubber elements - to replace.
6. To increase thermal insulation, you can use a heat-saving film. You will need double-sided tape to secure it to the inside of the frame.
7. With early detection and elimination of faults, room comfort is guaranteed.

By installing new plastic windows in the premises, their owners expect once and for all to resolve issues related to maintaining the optimal temperature and the desired microclimate inside. However, their hopes are rarely fully justified, because modern PVC structures can also present unpleasant surprises. More often than others, the following trouble is encountered - blowing from a plastic window. Moreover, the disadvantage is found not only in freshly installed structures, but also manifests itself in proven windows that have been in operation for more than a year.

What are the reasons for this trouble and how difficult is it to get rid of it? We will try to give answers to these questions in this article.

Where is blowing - sources of heat loss

All manufacturers of modern PVC windows promise customers ideal designs and excellent thermal insulation properties. But when it starts to blow from the plastic window, there are big doubts about the veracity of all the assurances and you only want one thing - to eliminate this deficiency as quickly as possible.

The first step is to identify the "weak link" - to determine from which part of the plastic window is coming through. The main ways in which outdoor air enters the room are:

• Places of the upper, lateral or lower fit of the sash to the window;
• Areas with defects in the seal;
• Slope butt seams;
• The lower part of the window sill.

If there is no thermal imager in the house, but you can't find a problem spot at a glance, you can take an ordinary candle (or lighter) and, when lit, move it near the window. In the place where it blows from a plastic window, the flame will flicker or go out.

After identifying the source, do not rush to accuse the window manufacturer of deception and unleash the full force of your anger on his head. Perhaps the plant has nothing to do with it, and the cause of the trouble is an incorrect installation or unfulfilled adjustment of the structure.

Quite often, the convection movement of air masses is mistaken for a draft. It occurs when there is a strong temperature difference outside and inside, when cold air from the window goes down and spreads around the room, creating the illusion of a breath from the window.

If you feel a draft from a new window, the period for which has not yet expired, call the master and seek to eliminate the negative phenomenon. If the defect manifests itself at a window that has been in operation for more than a year, then solving the problem will require financial costs or time for self-elimination.

Why is it blowing from the windows?

Blowing out of modern windows can occur for three reasons:

1. Due to manufacturing defects.
2. Due to the use of low quality materials.
3. Due to improper installation.

Deeper into each of the reasons allows you to more accurately identify the problems causing the negative phenomenon. Most often, window owners have to deal with the following:

• The window is unevenly installed and the skew allows cold air to enter;
• The fittings of the product are not adjusted, and therefore the sash does not fit snugly against the frame;
• The design is equipped with low-quality locks that are not able to tightly press the parts of the window to each other;
• A defect has occurred in the sash or frame profile. Poor quality plastic often cracks from cold temperatures or overheating in the sun;
• Contamination, damage or partial destruction of the seal - without maintenance and regular replacement, the seal begins to pass cold air. Cheap material breaks down very quickly;
• Incorrect installation and. Non-compliant thermal insulation is one of the most common causes of drafts;
• If it blows from under the sill of a plastic window, then the installation of the element is incorrect, and there are gaps between it and the monolithic base.

Let us consider in more detail the main points of blowing and the factors that caused their appearance.

Reasons for blowing plastic windows

However, in practice, this operation is not always performed, and therefore people have to deal with the problem on their own. Each window can be switched to winter mode, which strengthens the clamping of the frame to the sash and minimizes the likelihood of a draft. If you want to perform this operation yourself, check with the manufacturer for the procedure. If you do not trust your strength, then contact the window service centers.

Blowing from a plastic window - what to do?

If you have recently installed a new plastic window and noticed that it is blown out, contact the manufacturers and installers until the warranty period for the product and its installation has expired (note that the warranty period for work and for the structure itself may be different). Experts will quickly understand the causes of the draft and offer options for its elimination.

If you blow the beginning from a window that has been in operation for more than a year, find a place for blowing and try to determine its causes. Small drafts caused by insufficient thermal insulation can be removed by yourself. In more serious cases, you will have to contact the window repair and maintenance technicians.

In order to minimize the likelihood of blowing from a plastic window, use the following tips:

1. Buy quality products from reputable manufacturers. So you will receive a guarantee for the long-term operation of the structure and all its elements.


2. Do not trust the installation of windows to random people - installation work must be done. They have the necessary experience and knowledge, and therefore give a guarantee for their work. Specialists from service companies will switch the windows to the desired mode, explain the rules for caring for them and eliminate any malfunctions if they arise.


3. If you don't want to mess around with setting window modes, get modern models with automatic adjustment. The change in the degree of pressure is carried out using a round lever located on the sash. Turning it in one direction increases the pressing force, in the other - weakens.


4. Follow the manufacturer's recommendations and regularly take care of the fittings and gasket. Timely cleaning, lubrication and gluing of the seal will save it from destruction at the most inopportune time. Before the winter season, it is worth checking the condition of the joint seams: they may need insulation, sealing or renewal.

Why else can blow from a plastic window

If the blowing did not occur immediately, but several years after the purchase of the window, then the reasons may be as follows:

The listed factors more often than others become the reasons for the blowing of modern windows, but there are others. The source of the problem can be the discrepancy between the location of the locking elements with the striker plates on the frame, poor pressing of the handles to the base, as well as many other points. If you feel that it is blowing from your plastic window, but you cannot find the reason, do not waste time in vain, but call specialists from a trusted company. They will quickly assess the condition of the structure and suggest the best solution to the problem.

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 arises, why is this happening? And also what causes a draft from a plastic window?

Causes

Experts identify several reasons that can cause blowing.

These include:

1. Manufacturing defects;
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-crevices appear through which air can pass.

A bad effect on the quality of windows occurs due to improper storage of metal and plastic items 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 reasons for the appearance of a problem with plastic windows is poor-quality fittings.

Therefore, never no need to save money on buying and installing windows... Also blowing from PVC windows due to incorrect incorrect adjustment, which does not allow the sashes to adhere well to the surface.

Blowing from the side of the hinges

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 flaps 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 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 flap does not completely begin to press against the base, as a result, a small gap is formed through which air can pass.

Blowing between the sill and the plastic window

The most basic reason in this case is a poorly installed window.

During installation, the master used little polyurethane foam, shorting "is responsible" for reliable and correct fixation in the opening.

Eliminate blowing

To properly troubleshoot, it is important to clearly understand the cause of the blowdown.

If air passes along the entire perimeter of the sash, then the window has not been switched to winter time, that is, the fittings do not adhere sufficiently to the frame. The system needs to be regulated.

To do this, the pins, which are located along the perimeter of the flaps, must be simultaneously transferred to the maximum position (move clockwise). From the tools you will need a screwdriver or pliers.

This kind of operation must be carried out with an open window. The main thing is to find and turn all the pins, because the structure can break.

Some window manufacturers do this process automatically - the hardware is equipped with a roller with special rings. It rotates by itself and easily changes the mode from winter to summer.

Other reasons that provoke blowing can be eliminated like this:

• If the siphonite is from below from under the windowsill, the reason is in the installation (not hermetically sealed).
• The space under it needs to be re-rendered, and then plastered.
• To prevent blowing from the window, use a sealant. You may also need to reinstall the window sill.

Briefly about installing a window sill in a draft:

1. It is necessary to insulate and seal the window sill with polyurethane foam.
2. If the slopes show through, this means that the assembly seam is destroyed. Polyurethane 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.
3. If it comes through from the junction of the frame and the impost of the window structure, this indicates a marriage of the product. The gap must be sealed with a sealant.
4. If it blows out of the hinges, you need to look at the sash and close it tightly.
5. If the seal has dried out 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 glue plastic windows so as not to blow

There are situations where all the methods to fix the blowing problems are ineffective and fail.

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. This can actually be done using:

• Styrofoam;
• Expanded polystyrene;
• Mineral wool;
• Sandwich panels;
• Fiberglass.

Choose a material based on the size of the slots. Glue the material with assembly glue, then putty and paint.

There is also an option to seal the cracks in the plastic window. For this, ordinary scotch tape or a self-adhesive rubber or foam rubber seal 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 hassles. A special moment when windows have been incorrectly installed and not adjusted correctly.

So that you do not have such problems, order plastic windows only from trusted manufacturers, and entrust the installation only to specialists in their field.
