What if blowing from a plastic window? Draft elimination Cool air blows from a plastic window

Draft from windows is a fairly common phenomenon that is constantly faced by a huge number of people living in their own houses and city apartments.

Well, in cases where the "culprits" of this problem are old, cracked window frames made of rotten wood, this is understandable.

But sometimes modern plastic double-glazed windows also "sin" with this, the manufacturers of which assure of their absolute tightness and high quality. Then why is this happening? And what causes a draft from plastic windows, at the same time we will figure out how to adjust a plastic window so that it does not blow.

In fact, there are only a few major factors contributing to the occurrence of this phenomenon. It:

  • Manufacturing defect

First of all, this is due to the use of low-quality plastic, which can deform and even burst when the temperature drops.

Improper storage has a negative impact on the quality of products. For example, storing metal and plastic profiles outdoors or in rooms without heating also leads to their deformation. As a result, the quality of the installation also deteriorates, which leads to the appearance of drafts.

  • Low quality plastic and / or fittings

One of the most common causes of problems with plastic windows is low-quality fittings. Therefore, at this "point" in no case should you save money when ordering and purchasing them. In addition, blowing from the window can be due to its improper adjustment, which does not allow the sashes to fit snugly to the surface.

  • Errors made during the installation of the window structure

Even minimal deviations from a given plane, invisible to the naked eye, made when installing a window unit, can cause drafts in the house. Therefore, all assembly work must be carried out by experienced professionals.

In addition, a draft from plastic windows can appear if its interior is improperly finished: poor-quality installation and poor insulation of slopes (), improper installation of the window sill (resulting in a gap in this area), etc.

How to determine where is blowing from a plastic window

In order to eliminate the cause of the unpleasant draft that occurs in the area of ​​the window opening, you first need to find the place from where it blows. To do this, you need to take a lighted candle in your hands and bring it to the window sash, in the places where it is adjacent to the frame. You need to be especially careful at the joints of the window frame with the slopes.

If its flame begins to fluctuate strongly, then the problem really exists. If the oscillation of the candle is barely noticeable, then everything is in order with the tightness of the glass unit.

Having identified "vulnerabilities" for their elimination, it is better to contact the window installer, especially if they are still under warranty service. Or try to get rid of the cracks yourself.

If blowing from the side of the hinges

Blowing in this place can be due to incomplete filling of the mounting holes. To fix the problem, you need to carefully inspect the sash and close them tightly.

In addition, the cause of the draft that occurs in this area may be technological gaps for attaching a mosquito net or other additional holes located on the outside of the frame. As there is no need to use them in winter, they must be closed before the onset of warm weather.

In some cases, the wind at the point of attachment of the hinges may occur due to improperly mounted or poor-quality fittings. The problem is solved by replacing it or adjusting it.

Blowing from the handle of a plastic window

A cold breath from under the handle of a plastic window indicates that it has ceased to perform its functions in full.

That is, the sash of the window is not fully pressed against the base, as a result of which a small gap appears through which cool air passes.

Exit: it needs to be tightened, tightly clamping all fasteners, or replaced. For this:

  • The decorative strip covering the place where the handle is attached to the window block is removed. To do this, it is simply turned in any direction by 90 degrees, after which the fixing screws located under it are unscrewed.
  • Having removed the old handle, a new one is installed in its place and fastened with the same screws. Cover the fasteners with a decorative plate again.

After that, you need to check how tightly the new handle presses the sash. If necessary, the plastic window lock is additionally adjusted.

Blowing from under the glazing bead of a plastic window

If it blows into plastic windows through rubber bands, then the following factors may be the reason for this unpleasant phenomenon:

  • 1. Incorrectly selected seal.

Corrected by replacing it. The best option: silicone seals with excellent thermal insulation performance. You can buy them in specialized stores.

For this:

  • The old rubber gasket is removed.
  • The profile is thoroughly washed out from dust and dirt.
  • A new seal is glued on.
  • 2. Factory defects of the glazing bead (the leg is thin or deformed) or its insufficiently tight pressing to the frame.

It is also changed if necessary. Or, for additional sealing, the existing gaps between the frame and the glass unit are filled with silicone.

What to do when blowing between a window sill and a plastic window

The most likely reason for this phenomenon is poor installation of the window.

Simply put, during the installation process, an insufficient amount of foam was used, which is "responsible" for the reliable and correct fixation of the window block in the opening.

Remedy:

  • They remove the window ebb from the street side.
  • Remove old polyurethane foam (there is a possibility that it will not be there at all).
  • Thoroughly foam this place with high-quality polyurethane foam.
  • Install the ebb.

In case of insignificant blowing in the area between the window and the sill, sealing the joint with silicone can help.

Blowing from under the plastic window sill

There can be two reasons:

  • Violations committed when installing a window.
  • Worn seal.
  • Incorrect installation of the window sill.

In the first case, it is better to contact the company that installed the windows. They must solve this problem as soon as possible, especially if the windows are still under warranty. For self-elimination of inflation, you must:

  • Seal the gap between the window and the sill with a sealant.
  • If its dimensions are very large, you need to use polyurethane foam to fill it, and then reinstall the window sill.
  • Replace worn seals by attaching them with special glue.

If, after carrying out all the above measures, the draft still does not stop, most likely you will have to completely reinstall the windows.

Blowing from the slopes of plastic windows

Because of what: poor filling or no filling of the assembly seam. Because of this, cold air enters the room through the space between the wall and the window frame. This phenomenon can occur several years after the installation of the window. Reason: destruction of polyurethane foam.

What to do:

  • Disassemble the slopes.
  • Foam the seams carefully around the frame.
  • Reinstall the slopes.

How to adjust plastic windows so that they don't blow

Often a draft from a plastic window occurs due to its improper adjustment. This disadvantage can be eliminated by observing the following rules:

Pressure adjustment

  • It is produced from the end part of the window, at the location of three eccentrics that regulate its clamping, called pins. They are carefully turned with a hexagon. If you need to make the clamp more dense, they need to be turned to the left by a few millimeters, and to loosen them - to the right.

Fittings adjustment

  • In this case, you must pay attention to the blockage of the window. If there is an inscription: AUBI sash is installed vertically, after which it is necessary to press the metal strip with a spring, turning the handle to the correct position.
  • If there are the words: GU, ROTO, the metal tongue is adjustable under the handle. It is pressed on and rotated parallel to the seal.

Blowing from rubber bands

A draft from the seal of a plastic window (in other words: gum) indicates its partial or complete destruction. Over time, the seal shrinks and begins to crack.

You can try to seal up small cracks with glue, but nevertheless, such blowing is 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 seal for the existing plastic profile.

Do not forget to take a small piece of old rubber with you when you go shopping to make it easier to choose.

The adjustment didn't help. How to glue plastic windows so as not to blow

Sometimes all the attempts made to adjust the windows and eliminate the causes of the draft do not give the desired result.

This means that this problem needs to be solved in a different way. For example, by insulating plastic windows for the winter.

First of all, you can "improve" their slopes using the following types of insulation:

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

The choice of material should be based on the size of the available slots. It is glued with assembly glue, putty and painted.

As a last resort, the gaps in the plastic window can be sealed. For this, the following are suitable:

  • Scotch.
  • Self-adhesive rubber or foam rubber seal.

However, this should be done only in cases where a strong draft persists after all adjustments have been made and the assembly seams are carefully sealed.

In general, no matter how practical and convenient plastic windows are to use, even with them a lot of trouble can arise. Especially if they have been incorrectly installed and not properly adjusted.

In order to prevent their appearance, plastic windows should be ordered only from trusted companies and entrust their installation to specialists with relevant qualifications.

Installation of plastic windows is a very reasonable solution for owners of private houses and apartments. Such windows are famous for their high thermal and waterproofing properties. However, sometimes it happens that the window sill suddenly begins to blow, which significantly cools the room.

This is especially unpleasant in winter, when the temperature outside is below zero. What to do if blows through a plastic window? You will learn how to act in this situation right now.

Blowing out a plastic window - what to do? Looking for a reason

First of all, you need to figure out why this is happening. If you notice that the flap joint is blowing, the problem is probably hidden in a bad seal. It should also be noted that even the most expensive metal-plastic windows cannot guarantee you complete isolation from external factors for a long time. As a rule, the sealant "lives" no more than 3-4 seasons, that is, about 3-4 years of operation. After this time, this window element becomes more rigid and simply loses its properties. Gradually, small holes are formed in the seal, through which cold air from the street penetrates.

So, you found that your plastic window is blowing. What to do in this case?

There is only one way out of this situation - buying a new seal. You can buy it in almost any specialty store, and it is quite simple to install. And in order to be completely calm for a metal-plastic window, additionally purchase special care products for it. This will increase the life of the seal by another 1-2 seasons.

Another common reason for blowing through windows is the wrong one.In this case, you do not need to insulate anything. To rectify the situation, it is enough to pick up the hexagon and correct the direction of the flaps. Determining the sag of the window is also quite simple - when it is opened, the lower part of the sash will cling to the frame. In this case, blowouts will be observed in the upper part of the outer corner. How to adjust the sash, we will consider in the next subheading.

Getting started with the adjustment

So, we are blowing through a plastic window. What to do and how to adjust it? To adjust the hardware, you need a minimal set of tools. It is enough to have one hex and pliers.

On the fittings, you will see several elements - the lower and upper hinge, the pivot, the striking plates on the window frame and the scissors located on the tilt-and-turn fittings. With the help of the first element you can make yourself. Here it can be adjusted in 4 directions - down, up, left and right. Upper hinge supports clamping adjustment. Here you can also set the position of the window in a different direction (left or right). Elements such as pins and strikers are used to adjust the sash pressure.

What if cold air enters the room from under the slopes?

Earlier, we found out why it blows through plastic windows. How to fix the problem if air enters the room from under the slopes? First of all, you need to remove the slopes and additionally insulate the plastic window under them. If there is foam, carefully seal all joints and seams of the sealing element. The foam should fit snugly all over the window and its frame. If you doubt the quality of the work performed, dismantle the seal and install it again. In brick houses, in order to exclude blowouts, it is recommended to additionally plaster the wall underneath. It is quite possible to use polyurethane foam as a sealing element. It is very simple to use it - first it is applied to the wall, then the foam is tightly pressed against it. Excess cured foam is carefully removed with a knife.

After completing all of the above work, the slopes are mounted in their place, and the joints are sealed or closed using special casts.

A few words about mineral wool

Why sometimes, even after such a "repair", does it blow through a plastic window? What to do in such a situation? It's all about the sealing material. If instead of foam under the window you find it is best to replace it. The fact is that this material does not perform its thermal insulation function very well. Over time, the cotton wool simply rolls down, and blows are formed in the place of the formed cracks. It is for this reason that experts recommend using foam as the main thermal insulation material.

So, we found out why plastic windows are blown out, and how to fix this problem in various cases (depending on the place of depressurization).

With the onset of winter cold, many owners of plastic windows find blowing and drafts. The problem that has arisen takes place not only in new glass units, but also in old window openings. There are quite a few reasons for the wind that has appeared. Consider how to determine the location of the draft and options for eliminating it.

Blowing from plastic windows - looking for a reason

First of all, you need to make sure that it is blowing from the window and find a place for the resulting heat loss. To do this, we need a lighted match, a candle or a lighter. Sweep the flame slowly around the entire perimeter of the window frame. In the sinuses of air penetration, the fire will actively evade in the opposite direction. Subsequent adjustment and repair depends entirely on where the breakdown was found.

Blowing from plastic windows - the culprit is the firm

Most often, the problem occurs in slope clearances and in the frame attachment points. The culprit in this case is the installation company that performed the installation and did not follow the rules of operation and installation. There are three main reasons for inflation:

  • Defective glass unit.
  • Fittings and accessories are made of poor quality material.
  • The workers made gross mistakes when installing the windows.

If you have a warranty and it has not expired, the manufacturer is obliged to carry out repair work within 7 days after your request. However, if all warranty obligations have ended long ago, you will have to solve the problem yourself. And so, let's consider the possible causes and ways to eliminate them.


Blowing from plastic windows - setting the winter mode

Windows can also be blown out if they have not been reset to winter mode from summer. In this case, you need to open the sash and find all the pins. The larger the window opening, the more pins you will find. Please note that the adjustment mode is also located at the bottom of the window. Using a polyhedron or pliers, rotate each pivot as shown in the picture, while adjusting the sash pressure level. There is also a second type of windows - in them the trunnion must be pressed, then pushed out, as in the mechanism of a wrist watch, set the desired mode and drowned back into the window.


Blowing from plastic windows - repair of a window sill and slopes

To eliminate the source of the draft emanating from under the bottom of the window sill, it will be sufficient to walk abundantly with polyurethane foam, cut off the excess in a day and cement it. It is more difficult to get rid of drafts in slopes and openings. There can be two options - the destruction of the assembly seam due to the expired 10-year service life and the factory defect. In the first case, all slopes must be disassembled and re-treated with a new hermetic agent. In the second case, the double-glazed window can be issued back to the manufacturer and replaced with a new one. If your warranty has expired or if you installed the windows yourself, fill all joints from the outside with frost-resistant sealant.


Blowing from plastic windows - changing the seal

In addition to the fact that it is necessary to look after and wash the plastic window itself, you need to regularly clean, lubricate and replace the rubber seal. It is thanks to its functions that the window does not sweat, closes tightly and does not blow from under it. How long have you been replacing and cleaning it? As a rule, the shelf life of this element is no more than 5 years, then the rubber “loses weight” and ceases to perform its functions. If your window is showing through from under the stamp, then it's in it. To change the seal, you need a new one, as well as special glue and scissors.

  • Remove the worn-out rubber; this is done by lightly “pulling” it out of the bosoms.
  • Thoroughly rinse the surface and degrease with a solvent so that the following material adheres tightly.
  • Then, glue the perimeter of the entire frame with glue, and insert the new seal always completely, without separate pieces.

Work carefully with the material, it should not be too taut and too tight. If you have never performed this procedure, it is better to practice beforehand. To extend the life of a new seal, lubricate it with petroleum jelly or glycerin.

The determining factor for replacing old wooden windows with new ones, metal-plastic or PVC, is their ability to retain heat in a house or apartment. Naturally, when installing double-glazed windows, few people were interested in how they would behave in the future. Will the cold be allowed to pass through, is it possible to insulate plastic windows, if necessary, and should it be done? If so, how to prepare windows for winter and what is the best way to provide thermal insulation of windows and openings.


A plastic or metal-plastic window, like any composite structure, has weak points. It is they who are potentially possible "gates" for heat leakage from the room.

Where can blow from plastic windows

To understand why PVC is blowing out of the window, you need to inspect the nodes, and for this you need to know the constructive principle of the window block device.

The most common blowing spots are:

  • window glazing bead (glass unit holder);
  • rubber compressor;
  • window fittings (for example, blowing from under the hinges, into the handle);
  • the perimeter of the window frame - the junction of the slopes, window sill, walls.

How to determine where is blowing from a plastic window?

The presence of a defect in one of the components of the window block leads to blowing from the plastic windows. There are three ways to determine the exact place of heat loss of metal-plastic windows:

  • tactile with your hand. To identify the gap, it is enough to run your palm over the surface of the window block;
  • lighter. The search procedure is similar to the previous one, but the light is more sensitive to draft and can detect even the weakest blowing.
  • paper. A regular sheet of paper is pressed by a window (inserted into an open window and clamped by completely closing the sash), if you pull the corner of the sheet and it is easily pulled out, then the seal is not pressed down enough (this may indicate that the old seal in this mode does not press well against the frame) ...

Why blows from plastic windows - causes of heat loss

  • installation error. This is the most common reason associated with ignorance or non-observance of the correct technology for installing a plastic window. 15 years ago, this service was so in demand that everyone who had at least some idea of ​​installing window blocks went to the installer. Naturally, few people did the installation of PVC windows in accordance with GOST;
  • skewed windows due to shrinkage of the house. An urgent problem for residents of new buildings and wooden houses;
  • an attempt to save money. One of the strongest arguments in the competition is always the price, especially during the economic crisis. A decrease in price, often at the expense of quality: saving on foam, on heaters, ignoring the need to protect a heat insulator, using low-quality components when assembling windows - all this eventually led to the fact that the consumer was forced to change or additionally insulate PVC windows;
  • physical wear of the window components, in particular the sealing gum, or the weakening of the clamping force of the sashes;
  • violation of the rules for the operation of plastic windows, which consist in the need to wash the window seal, and treat it with glycerin. Such maintenance prevents the loss of elasticity of the seal and its cracking.

What to do if blowing from a plastic window

Obviously, eliminate the source of the draft. From a practical point of view, there are two simple options - call a master to repair and adjust (expensive) windows or do it yourself (cheap).

The desire to close up all the cracks on your own with improvised means is reduced to naught, because: firstly, it is not aesthetically pleasing, and secondly, there are no guarantees.

When it is advisable to attract professionals:

  • the plastic window was recently installed. The installer is responsible to the consumer for the reliability of the windows (if this period is covered by the guarantee);
  • the window opening is located at a considerable height (in a multi-storey building). It is better to entrust any high-altitude work to professionals (industrial mountaineering services). If the window is located on the second floor or higher, the performance of the work will be associated with an increased risk;
  • if there is a manufacturing defect. For example, obvious defects in workmanship or installation that appear during the warranty period;
  • replacement parts if necessary. It is better to install "native" fittings if it is necessary to replace individual elements of the window block;
  • work is carried out in the winter time. Knowledge of installation technology, and how to insulate plastic windows for the winter, allows installers to perform work quickly, without significant cooling of the living space.

However, often, the cost of attracting specialists is equal to the cost of installing a new window, and this fact makes it more profitable to carry out insulation work with your own hands.

What you can do yourself:

  • internal insulation of the window opening;
  • thermal insulation of the frame contour;
  • window sill insulation;
  • replacement of seals.

How to insulate plastic windows with your own hands

When to insulate windows for the winter

Repair and insulation should be done before the onset of cold weather. This is due to requirements such as:

  • more comfortable working conditions;
  • material requirements. Some building materials, such as dry mixes and sealants, can only be used within a certain temperature range. Otherwise, they lose their characteristics;
  • optimal humidity;
  • no draft;
  • the ability to simultaneously perform internal and external insulation;
  • reducing the risk of catching a cold for apartment residents.

How to insulate plastic windows at home

The choice of insulation depends on the place of inflation.

1. Insulation of window openings for the winter

To insulate the window opening, you can use different materials and methods:

  • polyurethane foam. Expanding, the foam fills all the voids around the perimeter of the window opening, preventing air movement. Due to the fact that the foam is 90% air, it is the ideal insulation. However, the foam needs protection from ultraviolet radiation, high and low temperatures. Hence, it is in itself inexpedient to use it;
  • mineral wool. Excellent thermal insulation material for insulating window sills and internal slopes. Cotton wool has a more limited range of uses for window insulation;
  • polystyrene / expanded polystyrene. It is used to insulate the slopes of plastic windows;

Note. Rigid insulation is used when the thickness of the mounting seam is no more than 3 mm, in other cases it is better to give preference to mineral wool.

  • silicone sealant. A reliable way to eliminate blowing between the plastic elements of the window;
  • dry mixtures for finishing slopes, used if necessary to insulate the window from the outside;
  • construction tape. It is glued on top of the sealant or instead of it;

Advice. It is not recommended to use ordinary masking or window tape, after gluing it on the plastic of the window frame, unattractive traces remain, which are difficult to remove without damaging the front cover.

2. Insulation of the window block

  • sealant;
  • construction tape;
  • sealant;
  • heat-saving film for windows (energy-saving);
  • mechanical methods of insulation, for example, tightening (adjusting) fittings.

After the question of how to insulate, we will figure out how to insulate a double-glazed window, a frame, a plastic, aluminum profile, etc.

How to insulate plastic windows outside

External insulation of windows is carried out in the following areas:

1. Insulation of slopes of plastic windows

The first step towards improving the thermal insulation properties of a window. Whatever insulation measures are taken in the house, until the slopes from the street are insulated, the cold will still flow inside. At the same time, external insulation allows you to shift the dew point, which will prevent the appearance of dampness and the development of fungus. Filling up the gaps is a temporary measure, as over time, the plaster layer will begin to crack and expose the polyurethane foam, which will collapse under the influence of atmospheric agents. But as a protection for insulation, plaster is an excellent solution.

How to insulate the slopes of plastic windows from the street

Work order:

  • material preparation (hard insulation);
  • cleaning slopes from dirt and protruding parts;
  • surface primer;
  • installation of insulation on glue solution or special glue foam. It is preferable to use foam, because it excludes wet work, has a minimum setting time, more reliably holds a sheet of insulation;
  • sealing all cracks with glue;
  • installation of perforated corners;
  • installation of polymer mesh;
  • plaster finishing.

Advice. When installing the insulation, you need to make sure that it overlaps part of the window frame and completely covers the assembly seam.

2. Insulation of ebb windows

To insulate the ebb, it is enough to foam all the cracks or place heat-insulating material in them. To avoid the ingress of water on the heat-insulating material, a metal window sill strip is installed on top. The plank is installed at an angle (at least 5 o), its horizontal edge extends from the facade (by 20-30 mm), and the side edges are folded up. It is recommended to seal the junction of the strip to the surfaces with a sealant.

Internal insulation of plastic windows

Insulation of windows from the inside of the room is carried out in the following areas:

1. Insulation of internal slopes of plastic windows

Internal slopes are less affected by external factors, but put more demands on the aesthetic component. Therefore, it is important to know how to insulate the slopes of plastic windows without losing the attractiveness of the window.

Work order:

  • crevice treatment: removal of dirt, removal of old foam, loose parts, etc .;
  • applying a primer;
  • sealing cracks with polyurethane foam;
  • removing excess foam after it dries;
  • installation of heat-insulating materials (foam or cotton wool);
  • installation of drywall;
  • finishing drywall with putty and paint.

2. Insulation of the window sill of plastic windows

The cracks between the wall and the window sill are one of the places of significant heat loss. Before deciding how to insulate the sill of a plastic window, you need to determine its weak point, i.e. from where it blows. For example, blowing is possible between the plastic parts of the window and the sill. In this case, it is recommended to use a sealant.

Heat loss between the window sill and the wall is also possible. In this case, the insulation is carried out until the installation of the window sill by laying a layer of heat-insulating material. And also after its installation - by foaming the distance between the window sill and the concrete wall or brickwork.

3. Insulation by adjusting the plastic window

Elimination of skewing of the PVC window sash

To reduce heat loss, you need to adjust the fittings (components) of the window block.

Replacing the seal in plastic windows

Elimination of blowing through plastic windows is possible by replacing the rubber seal. You can change the seal with your own hands, everything is simple there - just pull out the old seal and insert a new one into the groove (groove).

Which gasket is better? Please note that there are black and gray window insulation on the market. The black seal is more plastic, but the attractive light color is due to various additives that reduce the cost of the window seal and, at the same time, worsen its properties (tightness of pressing).

Additional ways of insulating plastic windows

  1. Washing windows. Paradoxically, cleaning the glass unit helps to save heat. After all, dirty glass loses its ability to transmit sunlight, but continues to transmit rays in the infrared spectrum.

  2. Blackout curtains. Which also trap heat indoors.

  3. Insulation of windows with improvised means. This method somewhat spoils the appearance of the window, but in critical cases, it can be a very worthy alternative to replacing the window block. Used as insulation: foam rubber, soaked paper, window tape, strips of white fabric, etc.

  4. Insulation of windows with heat-saving film. The energy-saving film is glued to the entire surface of the window (sash). The main thing is to stick it correctly, without air bubbles and folds. The film reduces heat loss through glass by 75%.

  5. Electric heating of a window. In this case, a heating cable is located around the window, which heats the heating coil, or an oil radiator is installed on the window.

  6. Electric heating of a double-glazed window. The most technologically advanced way is to install plastic windows with heated glass. The technology is applied at the stage of window production. Provides for the installation on the inside of the glass of a special conductive film (transparent film with conductive threads), which heats the glass from the inside.

  7. A complex approach. It is most suitable for insulating windows in an apartment or a private house, since it eliminates all possible causes of heat leakage through metal-plastic or PVC windows.

Conclusion

Insulation of windows often negatively affects the ventilation in the room. Full tightness is protection from the cold, but it is also fogging of the glass, which leads to the destruction of slopes and the appearance of fungus. The problem is solved by periodic ventilation of the room, micro-ventilation, installation of forced ventilation, etc.

The winter season 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 is blowing from a 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 subzero temperatures, cold air circulates not from the street, but from the home side (inside). The glass cools down, which is exactly what makes us think that the window lets the cold through.

To understand does the plastic window allow the cold, use this method - bring the burning candle close to the window sash in the place where it touches the window frame. If you see that the fire began to fluctuate strongly, then it is definitely blowing from the windows, and if the flame is direct, then this indicates a good sealing of the window structure - then the reason lies elsewhere.

You have to go through the candle along the entire perimeter of the structure and then you will determine exactly where the problem areas are. More often the cold comes from those places in which the window frame butts to the slopes, it is here that the most vulnerable places are located. The reason for this is poor-quality installation, but it blows from the slots in the slopes or under the windowsill. If the window has not yet expired, then it is better to contact the company that installed the window for help and demand that they solve the problem. They will definitely respond and send you a wizard 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 reason becomes. Dealing with such a problem can be done quickly and easily. The window structure must stand correctly in its rightful place. True, it is still better to entrust these works to a professional.

It often happens that during the installation of the window, a violation of the geometry of the window structure was made, because of this, the sashes do not adhere well to the frame, which causes drafts.

In this situation, it is impossible to adjust anything; 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 may become, more often this is done underground in China or in Turkey. Of course, such accessories are much cheaper, but on the other hand, their quality will correspond to such a price. Therefore, you need to buy and order the installation only from trusted companies.

The next reason for the appearance of cold can be, which, under the influence of subzero temperatures loses elasticity... Moreover, not only the poor quality of the seal can cause drafts, but also its pollution. 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 with better performance and longer service life. Very often, drafts can be caused by poor quality plastic which is made from cheap raw materials. Such plastic differs from good plastic in that ultraviolet rays and high temperatures, with prolonged exposure, begin to destroy it, as a result of this, in the autumn and winter, cracks often appear on the window structure. Such a profile can no longer be repaired.
