Why is blowing from under the plastic window sill. Blowing from plastic windows

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 cracks appear through which air can pass.

A bad effect on the quality of windows occurs due to improper storage of metal and plastic things in the open air or in rooms where there is no heating. As a result, the quality of the installation also deteriorates, which then contributes to the occurrence of blowing.

One of the most common reasons for the appearance of a problem with plastic windows is poor-quality fittings.

So 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 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 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 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 the 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 was not transferred 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 should be performed when 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 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 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, you need 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 shrinks and becomes 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 when all the methods to fix the blowing problems are ineffective and give no 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. 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 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.

How to choose plastic windows is written.

Plastic windows have long and firmly established themselves in life modern man, they decorate the facades administrative buildings, apartments multi-storey buildings and country cottages... These practical and inexpensive window designs can be seen all over the place. Why did such a design receive such wide use and recognition? The answer to this question is obvious: the ratio of reasonable price and excellent quality.

But, nevertheless, it should be noted that there are exceptions to the rules ... You decided to install it in your house (apartment), but are you afraid of rumors that such situations are allegedly often observed when they leak air? Unfortunately, this sometimes happens, even if your window structure is made in a specialized workshop.

The reasons for this unpleasant phenomenon can be:

  1. manufacturing defect;
  2. use for the production of low-quality plastic;
  3. mistakes made during the installation of the structure.

So, blowing from a plastic window, what to do? First of all, you need to more accurately determine the place from where the cold air enters the room. You can cope with this with the help of the old "old-fashioned" method - it is enough just to hold the flame of a lighted candle along the frame and double-glazed windows. It is a perfectly reasonable cause that it may become inappropriate.

But first things first. Even by ordering elite windows from foreign manufacturers, you cannot protect your home from such a phenomenon as blowing plastic windows, which is why, with the onset of the cold season, many owners of such windows feel all the delights of this design.

What exactly did you encounter: manufacturing defects, low-quality plastic and fittings, or perhaps the problem of unfair installation of the structure? Only a specialist can give an unambiguous answer to this question. However, the answer can be rather vague and ambiguous, windows can let air through for several reasons at the same time.

Blowing from the side of the hinges

The reason for this phenomenon can be low-quality fittings that were used in the production process of the structure, as well as its unscrupulous installation. It is possible that your window is not installed perpendicular, but tilted. It is this flaw of installers that can cause such a phenomenon as blowing plastic windows. In order to correct this situation, it is necessary to replace low-quality fittings and install the structure correctly.

An equally common reason for such an unpleasant phenomenon may be insufficient pressing of the seal against the sash. In such a situation, especially in the cold season, when the temperature outside the window drops, the plastic is somewhat reduced in volume, plus, in addition, the sealing rubber may simply dry out. In view of this, it will not be able to hermetically seal the sash to the frame.

If functionality fittings are limited, perfect pressing of the sash to the surface of the frame is simply impossible, in places where the sash does not fit snugly, you will constantly feel how it blows. The solution to the issue is the replacement of accessories.

Draft, cold, discomfort

An equally common cause is sagging of the hinges as a result of careless operation of the structure. The sash simply sags, changes its geometric parameters. It is quite possible to correct the situation by adjusting the window fittings or by changing the position of the glass unit in the sash (re-linking the window).

Blowing in the area where the frame meets the window sill

The most common problem faced by the owners of modern window structures... The fact is that they are attached to the opening using special fasteners (anchors, etc.), then the structure is fixed with mounting foam. In order for the foam to subsequently not sag and not lose its properties, it is necessary to remove its remnants in time and carefully putty the sections.

Also, similar problems can arise as a result of poor-quality installation of the structure, that is, during the installation process, the installers simply saved on mounting foam. An insufficient layer of it will inevitably lead to a rapid subsidence of the structure. In this situation, even multi-chamber double-glazed windows will not save you from the penetration of cold air from the street, since the reason for blowing is an unscrupulous installation of the structure. The result is those who cannot cope with their own functional responsibilities windows, draft, walking inside the room.

Blows between side wall and frame

The reason for this phenomenon is quite simple - poor-quality installation, material savings, unscrupulous work of installers. A way out of this situation can be the dismantling and reinstallation of the window structure or high-quality sealing of the seams between window frame and a side wall.

But, all the same, what to do in situations when a plastic window lets air in from the street?

First of all, don't panic. If the window structures are under warranty service, you should contact the company that was engaged in the production and installation of the structure. The warranty period depends entirely on the quality of the goods, materials and accessories that were used in the process of its production.

Today, many manufacturers of PVC window structures provide warranty service for their systems for 5-15 years. Thus, each client has the right to independently decide where to purchase such a structure - in a dubious handicraft workshop, which may cease to exist tomorrow, with all the ensuing consequences, or in a reputable company that has been on the market for several years, which can give a long guarantee and provide quality service.

Thus, the only correct conclusion can be drawn - the warranty period reflects not only the manufacturer's reliability, but also a responsible attitude towards the client.

In the event of any malfunction, you must immediately contact the company where this design was produced. If the warranty period for your window structure has expired, you can always find intelligent and competent specialists who will help you cope with various problems. Remember, in such situations you need to trust only professionals - the warmth and comfort of your home depends entirely on this.

Thermal insulation of wooden windows is a great alternative to buying PVC profiles for two reasons at once. Noise and heat insulation properties of the insulated wooden frame no worse than those of a plastic window. In addition wooden windows"Breathe" and are much more environmentally friendly than PVC profiles with plastic frames. Therefore, if your window began to blow, then there is only one way out - to insulate it.

Step # 1: prepare materials

As soon as you find out that you see through the window, stock up on everything you need to fix this problem. To seal windows, you will need, first, a liquid for processing the surface to be glued. It might be normal ethanol or vodka. Take care of the filler with which you will lay the gap to let air in from the street. As a rule, they still use old newspapers, cotton wool or unnecessary textiles. Finally, you will need masking tape or medical tape to secure the seal to the outside. Do not take stationery tape, when cold weather sets in, it will peel off and blowing will resume. In addition, unlike the plaster, it heavily stains the frame when peeled off.

InMyRoom tip: special insulation for windows is now sold in stores, it already has a sticky edge, which greatly facilitates the gluing process. The amount of such insulation depends on the size of the window itself. One window usually has at least 10 meters of insulation.

Step # 2: clean the surface from dirt

The process of gluing windows is simple, and a person who has never dealt with this problem can easily cope with it. First you need to prepare the surface of the frame in the place where the gap is found: remove dust, dirt and degrease. Take any liquid containing alcohol, it can be vodka or pure alcohol, soak a rag in it and wipe the frame well. The higher the percentage of alcohol in the liquid, the better the surface will be cleaned. Wait a while for the liquid to dry.

InMyRoom tip: do not neglect the surface degreasing process. If you do not remove plaque and dust from the frame, then the material with which you are going to seal the windows will lose its adhesive ability and will hardly fit tightly.

Step # 3: seal the cracks

After the cleaned surface is dry, you can proceed directly to the use of the seal. Nothing complicated - just plug all the cracks in your field of vision as tightly as possible. If you use paper or textiles, you can pre-wet it and roll it into a tight flagellum - after drying, it will fill the cracks much better than dry material.

InMyRoom tip: if the gaps are very narrow and difficult to fill by hand, use an ordinary kitchen knife. Twist the small flagellum and use the tip of a knife to push it into the gap. Do this until the gap is completely filled.

Step # 4: glue the frames

When all slots have been thoroughly filled, check to see if cold air is entering through the slots. If so, add some more sealant to the place from where it comes through, if not, start gluing the frames. To do this, we need masking tape or plaster. Press it with your palm to the surface and, not cutting off, but gradually unwinding, glue the blowing place. If the gap is large, you can glue it in two or even three rows. Press the tape or tape firmly against the frame. Perhaps it will peel off a little at first. This is because the temperature at the blowing point is too low for the adhesive surface to adhere to the window frame. After a while, this problem will disappear. If the scotch tape does not stick, then it is not suitable for pasting windows, you should choose another one. After the patch has seized, check to see if the blowing has stopped. If the cold is still felt, you can re-glue this place, already with a denser layer.

InMyRoom tip: you can check if there are any gaps by slowly running your palm over the frame. If it is colder in some place, most likely, air from the street is still getting there. There is another way to check the blowing - with the help of an ordinary match. Light it and bring it to the window, the place where the flame goes out or begins to vibrate, most likely, continues to come through.

With the very first autumn colds, you began to notice that the windows let the cold through. It is quite a common problem, but after all, your window structures are plastic, characterized by tightness and minimal heat loss, so why does it blow from plastic windows?

Recently installed windows are still under warranty, so do not look for the reasons for 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, but why spend money if many defects can be corrected on their own?

Let's understand the problem. It is possible that you only need to learn how to tighten the plastic windows so that there is no blowing, 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

There is no need to immediately assume that the problem is due to structural defects or incorrectly conducted installation works... Don't get ready for a major renovation until you find a cold air source. To analyze the situation why it is blowing through plastic windows, an ordinary candle or 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 is in contact with the walls and the window sill. Don't forget about the hinges, handle and rubber seal.

How to adjust a plastic window to keep from blowing

The main reasons for blowing plastic windows:

  • incorrect adjustment - blowing from the sash of the plastic window due to the fact that it is not transferred from summer mode to winter;
  • manufacturing defects - poor-quality profile reinforcement, damaged glass unit, used cheap plastic, which may not withstand temperature extremes;
  • low-quality fittings and gaskets are those parts of glass units that you never need to save on, so choose the most reliable fittings;
  • unprofessional installation - incorrect installation, there is no insulation of the slopes, the window sill is not installed correctly, the geometry of the structure is broken;
  • the number of double-glazed windows does not correspond to your climate zone.

Note! If it blows from a plastic window, you automatically have a kind of ventilation in the room and the double-glazed windows do not fog up. By eliminating the problem of drafts, you can get a completely opposite problem. If your windows are plastic, 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 doesn't blow?

Seasonal adjustment of window structures means the change of the summer micro-ventilation mode to the winter one, when the sashes fit more tightly. Most often, simply by changing the degree of sash pressure, you can completely remove drafts in the house.

If plastic windows are blowing along 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 sash of PVC products, thanks to which a tight fit to the frame is ensured. The clamps are in the form of eccentrics with a recess for a 4 mm Allen key.

By simply turning the eccentric, adjustments are made to:

  • Winter mode, when you need to ensure the most snug fit. To do this, all trunnions along the perimeter of the flaps are moved clockwise to the farthest position so that the longest radius is directed towards the room when the frame is closed.
  • Summer mode, when the window eccentrics are turned to the shortest radius towards your room. In this position, there is a minimally dense vestibule: air flows freely through the doors and the room is constantly ventilated.

Important! Before starting work, find all the pins so that you can turn them at the same time, otherwise the metal-plastic window structure will break.

Please note that many manufacturers have automatic switching from summer to winter mode. In such designs, all the accessories are completed with a special mechanism - a roller with a rotating ring, with the help of which the clamping of the sealing rubber to the frame is weakened or strengthened.

Blowing from the side of the hinges

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 the unfilled mounting holes in order to subsequently close them. There are a lot of various fastening elements around the hinges, passing inside the frame through the plastic itself.

As an example, there may be holes outside the frame for attaching a mosquito net. Air can enter these cavities, which through the frame in the area of ​​the hinges and will enter the room, creating a draft. Simple sealing of the holes quickly solves such a rather serious problem.

Adjusting the fittings of the plastic glass unit

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 the wrong ways of installing it. Hopefully, it will be enough to simply tighten it, but more often than not, you have to buy new fittings to avoid drafts in the winter.

Blowing from under the windowsill

Blowing out from underneath clearly indicates that the sill is not completely airtight. When installing double-glazed windows, the builders had to qualitatively fill all the space under the windowsill with mounting foam, while not saving it.

Important! After filling with polyurethane foam, it is imperative to plaster the treated space under the windowsill. This is done not for beauty, but so that the foam, under the influence of external factors, does not collapse and new foci of drafts do not appear.

If blowing from the windowsill of a plastic window, you will need to treat all the cracks where a draft is felt with a sealant. 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.

Blowing between the frame and the slopes, the windowsill

Another similar reason associated with poor quality installation. This can be argued if the double-glazed window was installed quite recently. If the plastic structure has been used for a long enough time (at least 7-10 years), then you need to understand that over time, the foam always begins to wear out and break down.

This problem doesn't show up overnight. A good host 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 stopped with sealants, but this is only a temporary measure.

If blowing is detected in the place where the frame is in contact with the window sill, we can also talk about careless builders and about saving foam. The frame is attached to the opening with appropriate anchors, then everything is insulated with foam and plaster.

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 still, 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.

How to glue the plastic windows so as not to blow?

Sometimes it seems to you that the double-glazed window is showing through, but in fact it just comes as if cold from it. This is most often observed in the lower parts of the valves. This is not blowing at all, since the draft is not detected.

The chill from the windows can be explained by the fact that you have:

  • a single-chamber double-glazed window is installed;
  • the number of double-glazed windows is insufficient for your climatic zone;
  • heating does not work well;
  • heating batteries are blocked by a too wide window sill;
  • too powerful ventilation is installed.

It is not difficult to insulate 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 guidelines.
