A double-glazed window burst: reasons, what to do? Cracked plastic window: causes, repair Where to order repairs.

When new plastic windows are installed in the dwelling, the residents are overwhelmed with joy, and the rooms immediately become lighter, cozier and more comfortable. But, unfortunately, there are cases when a crack appears on a double-glazed window for some reason. Such a phenomenon will not please anyone. The first question that the owner asks is: why did the glass burst? Please note that urgent replacement of double-glazed windows is carried out by specialists using the link to the website http://oknovita.ru/.

Causes of glass cracks

Causes of cracks in window glass there may be several. Here are the most popular ones:

• Glass defect.
• Frame tilt.
• temperature fluctuations.
• Mechanical damage (impact).
• Installation errors.

Any of these factors can cause a crack on the double-glazed window of a plastic window, and if they are present in combination, this risk increases several times.

What to do if a double-glazed window burst

Some owners of plastic windows, having found a crack on a double-glazed window, panic. Out of ignorance, they think that they will have to completely replace the window, and this is repair again, all the inconveniences that it entails and, of course, unforeseen financial costs. But this is not so at all. If the glass in the plastic window is cracked, it is enough to replace only the double-glazed window. You can of course go the other way and replace only the damaged glass. But this method has significant drawbacks:

• this work is quite laborious;
• it takes a lot of time to replace one glass;
• you need to find identical glass;
• the tightness of the double-glazed window is broken, which will lead to the accumulation of condensate inside it (perhaps this drawback is the most unpleasant).

Glass replacement process

Replacing a damaged double-glazed window with a new one is a very time-consuming task for those who are not familiar with such work. But for a specialist, the whole process will take a few minutes. Therefore, it is better to entrust such a procedure to a master who knows his business.

The first step is to remove the glazing beads from the window. To do this, use a wide chisel or shoe knife. Now the double-glazed window is removed with a plastic spatula and special suction cups. In the fold, you must first install the adjusting pads. Very important point: the lining must be located under all glass panes of the double-glazed window. If the replacement takes place in a blind sash, one adjusting lining is enough, which is placed in the middle.

When replacing a double-glazed window in an opening sash, two linings are used, which are installed with an indent of 10 cm from the edges. Then the double-glazed window must be aligned along the perimeter of the sealing rubber, for which the same plastic spatula is used.

The next stage is the installation of glazing beads, which is carried out in reverse order. If, during dismantling, the long ones were first removed, then the installation should begin with the short ones. Here you need to use a mallet or a plastic hammer.

The service is not of good quality - what to do

Many customers of firms involved in the installation or repair of plastic windows faced the problem of poor quality service. It is quite understandable that the customer wants to receive partial or full compensation for the actions of negligent craftsmen.

Plastic windows (double-glazed window burst)

But not everyone knows what needs to be done for this.

First, a dissatisfied customer must file a complaint, in which he must indicate his claims and demand replacement or material compensation for damaged property. The complaint must be drawn up in full form, that is, it must contain the details of the defendant, the name of the applicant, the date, the main requirements.

The document is written by hand in two copies, copies of checks or warranty cards must be attached to it. The originals remain with the applicant. It is best to first try to resolve the conflict directly with the defendant firm. But not always the claims of the customer are satisfied peacefully.

If the company does not admit its fault and refuses to compensate, the client with his complaint must contact the consumer protection society, which will appoint an independent examination. In the event that the results of the examination turn out to be on the side of the plaintiff, he can apply to the court and, by its decision, receive appropriate compensation for the material damage received. In some situations, it is possible to file a claim for compensation for moral damage.

Broken glass repair

If the glass in the double-glazed window is cracked at the plastic window, then do not despair. Such damage can be repaired. If you contact a specialist, the work will be carried out as soon as possible. In winter, this damage should be given Special attention, as the room will penetrate cold air, frost may form on the windows. At the same time, it is worth considering that during the work itself in the house, you will have to endure a drop in temperature for some time.

Causes of cracks

Causes of cracks in window pane can be all sorts of factors. The most commonplace is mechanical damage. Accidental impact may cause cracking.

The cause of damage may be improper installation of the plastic window. If, during window assembly, the double-glazed window was installed incorrectly in the frame, with an offset, then this can lead to excessive load. This, in turn, leads to the appearance of cracks. Also, if the frame itself, when installed in the window opening, was installed crookedly, this may cause damage.

If the glass in a plastic window bursts, then thermal shock can cause damage. This phenomenon is observed in the case of uneven heating of the glass in the case of a sharp temperature drop. The difference in pressure can also lead to glass cracking.

If you close and open the window with strong pressure, constantly slamming, then this also leads to a decrease in the strength of the glass, up to its cracking. Therefore, careful attitude to the design is important.

Determine the exact cause (with the exception of mechanical damage), only the master can. To do this, glazing beads are removed from the window structure and the window is examined.

If the inner glass is cracked, then everything is clear without consulting the master. Such a defect appears only in the case of poor-quality manufacturing of a plastic window or if it is installed incorrectly.

Cracked Glass Repair

Most reliable way fixing a crack in the glass is a double-glazed window replacement. It is recommended to replace the entire double-glazed window. This is due to a number of reasons:

1. Replacing only one glass is a very difficult job that requires a significant amount of time: the glass must be separated from the double-glazed window, a similar material of the same thickness and dimensions must be found, and then glued.
2. After removing one glass, the tightness of the double-glazed window is broken. Inside it is silica gel, which loses its properties after the depressurization of the system. This will lead to the fact that condensation will constantly form inside the double-glazed window.

Replacing a double-glazed window eliminates these problems. The master immediately determines the thickness and size of the double-glazed window, selects an analogue for him. Then a new node is installed.

However, in winter this method is accompanied by a number of difficulties. As a rule, replacement requires a certain amount of time: inspection, departure of the master to the warehouse, selection of glass, return to the installation site and the installation itself. IN very coldy this can lead to severe cooling of the room. However, there are no other ways.

If the warranty period has not yet expired on the plastic window, then you should contact the company that installed the window. This is especially true if the damage appeared due to a manufacturing defect or poor-quality installation of a plastic window. In such cases, repairs should be carried out free of charge.

Replacing only one glass is also cheaper than replacing the entire double-glazed window. And if you repair double-glazed windows with your own hands, then you only need to spend money on the material. However, the quality of the work carried out will be questionable. In addition, the probability of maintaining the tightness of the structure will definitely be excluded.

Some companies remove the entire double-glazed window and replace one glass in a production environment. In this case, special equipment is used, which allows further drying and re-sealing of the double-glazed window.

If you have a small crack, then you can live the winter with a cracked double-glazed window.

Why did the glass pane crack?

A small crack can simply be sealed with transparent tape. This method is short lived, but small defect quite acceptable. And the winter will allow you to survive completely with a comfortable indoor temperature.

Damage prevention

Cracked glass leads to additional costs, time and labor to repair. In order not to burst a double-glazed window, it is necessary to prevent the possibility of damage. Of course, it is impossible to protect the window from accidental mechanical damage. The only option is to use impact-resistant glass. In a double-glazed window, tempered glass or triplex can be installed. Such materials will last a long time and reliably, you need to make every effort to break such glass. It is much easier to limit yourself from other factors.

You need to order a window from a reliable company. You can learn about it from relatives and friends, from consumer reviews, etc. The production of plastic windows in such companies is well established, which minimizes the manufacture of structures with manufacturing defects. Qualified specialists will carry out the work in full accordance with the installation technology. In addition, products and services are warranted.

During operation, the sash must be opened and closed smoothly, without bumps and sudden movements. If over time the sash sagged a little, then they should be adjusted. It is also worth lubricating the mechanisms of the structure, so that the windows will work efficiently. You don't have to make any extra effort to open them.

You can not strongly heat the window, direct it at it hot air. For example, if work is being done with building hair dryer, then contact with glass should be avoided.

Also, learn the rules for the care and operation of plastic windows in this article.

Therefore, repair cracked glass in winter period not only possible, but necessary. Decide which repair option fit better in total and with the involvement of what forces it will be carried out, independently or with the help of qualified specialists.

If you find any defects in the window, then the question immediately arises, who is to blame for this and how it can be eliminated, whether the solution to the problem will fall on the shoulders of the window manufacturer or will have to be corrected at your own expense. In order to deal with defects in a double-glazed window, you need to know what influenced their appearance. Consider possible problems and their causes, as well as figure out what can be done with different types troubles formed on the glass.

What to do if there is a crack in the window

Glass pane is separate part wooden window, in which glass is hermetically soldered. With a crack, the tightness is broken and repairing it is economically unprofitable for the customer and easier to replace. Possible reasons cracks in the glass:

• mechanical impact. This is the most common cause of cracked windows. The crack may not appear immediately after impact. And a crack from the side of the street may appear due to a branch or some object that was thrown by the wind.
• temperature difference.

  Why do double-glazed windows burst from heat?

  If the crack was formed due to this reason, then the company that installed the structure is most likely to blame, because. she chose the wrong method of installation, not taking into account the climatic conditions of the area.

• Artificial temperature difference. This may occur if the winter time years, with a minus on the windowsill boils Electric kettle, thereby artificially obtaining a large temperature difference with different parties double-glazed window.
• Wall displacement. When the house shrinks, there may be problems with double-glazed windows in houses made of timber or logs. In these cases, the window is made taking into account further shrinkage. The problem can only remain if the double-glazed window was made with a slip in the shrinkage prediction. Installer companies usually warn about possible problems associated with shrinkage.
• Mounting error. Such a cause is usually not immediately identified, but can also cause cracks and other window problems.

If you see a crack in your double-glazed window, which appeared through no fault of yours, first check whether the warranty period for the design and installation has expired. If the warranty has not expired, then you need to contact the company that was involved in the installation.

If the warranty period has expired, you will have to repair it yourself. It will no longer be possible to close the crack, because. the double-glazed window was depressurized and got into it wet air and the window will now not fully perform its functions. Glass needs to be replaced for repair. You can do it yourself or contact the company for glass replacement and necessary repair actions. If you do not know about window construction devices, then it is better to call a specialist. First you need to determine the cause of the cracked window in order to avoid repetition, and then proceed with the repair.

What to do if condensation appears inside the double-glazed window

If condensation or, in other words, moisture has appeared inside the double-glazed window, for example, after rain, then it is necessary to contact the manufacturer or the company that carried out the installation. the tightness of the double-glazed window was broken. Complex diagnostics will be required to determine the cause. Actions should be taken depending on the diagnostic results. One of the reasons for this trouble may be a manufacturing defect. In order to remove this moisture, a desiccant is poured into the double-glazed window. Perhaps the manufacturer miscalculated required amount desiccant. This should not be delayed - when frost sets in, frost may appear inside the double-glazed window. Unfortunately, this problem cannot be fixed at home.

If the condensate has formed due to the low thermal properties of the window, i.e. glass and profile are not warmed up enough. In this case, you will have to replace the window with another wooden one or replace the double-glazed windows with top-coated double-glazed windows (which reflect heat), which will be a cheaper option. If indoors high humidity, then this can also be the cause of condensation inside the double-glazed window, then it is enough to ventilate the room more often.

In the event of an installation error, moisture inside the double-glazed window does not appear over the entire area of ​​the window, but in narrow stripes. This is solved by sealing the seams that allow air to pass through, using polyurethane foam or window removal. You will have to remove it, clean it from the remnants of the old mounting foam and install it again.

What to do if you find bubbles and scratches on a double-glazed window

If in installed window if you find bubbles, then you should not sound the alarm ahead of time. There are norms according to GOST, according to which a certain number of bubbles is allowed inside the double-glazed window. If the number of bubbles exceeds allowable rate, then you should contact the manufacturer for a replacement, because. this is a factory defect and the double-glazed window should be replaced under warranty. If after installation you find scratches in the double-glazed window, then it must also be replaced under warranty, scratches are not allowed for any brand of windows.

What to do if you find stains on the window

If you find iridescent streaks or spots on the window, similar to glare on water that has got oil or gasoline, then most likely the glass was not washed well during assembly. The surface of the glasses may be contaminated during manufacture, for example, with oil or a special liquid, which should have been removed immediately before the assembly of the double-glazed window. In the event of such stains, the double-glazed window must be replaced under warranty.

Rainbow spots and stripes may also appear for other reasons:

• Glass surface corrosion. Occurs due to improper transportation and storage of glass. Should be replaced under warranty.
• Glass flatness defect. Iridescent stripes are visible on double-glazed windows with a special tinted coating, which appears when the glass tempering technology is violated. If such bands exceed the deviation permitted by GOST, then the manufacturer must replace the double-glazed window.
• Stains on the underside of the glass are also considered a manufacturing defect.
• Small iridescent spots, like "leopard skin" near tempered windows, visible under a certain acute angle not considered a defect.
• Iridescent rings on the surface of the glass may appear due to the deflection of the glass. This can happen if there are violations technological processes in the manufacture of insulating glass. It is considered a marriage and must be replaced under warranty, tk. the thermal properties of the window will be degraded.

As you understand, there are quite a few reasons for the appearance of stains on a double-glazed window, mainly due to a product defect and subject to warranty replacement. In each case, diagnostics will be carried out.

Sometimes owners of plastic windows turn to us with such a problem - plastic window glass burst. As a rule, they do not know what caused this, because far from always trouble occurs due to a blow from the outside or from inside.

One of the four parties may be to blame for the fact that the glass in the double-glazed window has burst. It's about about the owner, about the company that carried out the installation, about the manufacturer metal-plastic construction, or external factors. In short, the owner is to blame for the fact that he used the window incorrectly or carelessly, the installer made mistakes during installation, the manufacturer released a marriage, and external factors are beyond human jurisdiction.

Without delving too deeply into the whole philosophy of the issue, we will consider the most basic reasons due to which a double-glazed window may burst, not taking into account the direct mechanical impact. In fact, there can be a lot of them, but we have identified 6 of the most common. So let's get started.

Improper installation of windows and double-glazed windows in particular

If you make a mistake during the installation of the metal-plastic structure, then there is a possibility that the window will be installed crooked. Over time, an even greater bevel will go, and as a result, under the influence of mechanical pressure, trouble will happen, and then the owners will wonder why the double-glazed window in the plastic windows burst.

It is also worth noting that the installation of the double-glazed window itself is the final stage in the installation of the entire metal-plastic structure. And quite often the masters at the finish line try to finish quickly. As a result, due to the banal haste, they incorrect installation of gaskets for double-glazed windows- these are special plates that are laid out along the perimeter between the double-glazed window and the sash. What happens? Due to the wrong position of the gasket, due to its incorrect installation or due to its size, uneven pressure is created on the window. If a double-glazed window bursts from the inside, then the first thing to do is to look for the reason here, and only then check other options.

Window frame offset

Sometimes it happens that the plane window frame is changing. This is usually due to an installation error. One of the corners of the window can be pulled either inward or outward. If not noticed in time, this will lead to the formation of a crack. The fact is that the glazing beads quite tightly press the double-glazed window. If it takes the form of a frame, then, most likely, this will entail the appearance of a crack.

Who is guilty? In most cases, the company that installed the metal-plastic structure.

temperature shock

Some owners of plastic windows are interested in whether the guarantee is valid if the double-glazed window burst due to thermal shock. It is difficult to answer regarding the validity of the guarantee, but if the window cracked due to the temperature difference, the installer company, which chose the wrong installation method, is to blame. Thermal shock is the difference in temperature effect on window glass. For example, one glass of an insulating glass unit can get very hot, while the other does not. Can a double-glazed window burst from the sun? Theoretically, yes, it is possible. As a result of uneven heating, the glass will deform, and as a result, cracks may creep along it. However, it is not necessary that the impact on the window structure should be from the outside. If, for example, there is a big minus outside the window, and you start boiling a kettle on the windowsill, then you can create the same temperature shock.

This problem especially concerns aluminum windows. The fact is that in them a double-glazed window is surrounded by metal. That is, even the slightest vibration can be transmitted to the glass. If the distance between the double-glazed window and the frame is small, then the glass will gradually begin to crack until it bursts.

Marriage in production

Quite often it happens that the double-glazed window was initially defective. That is, a small imperceptible crack formed in it at the factory, which could manifest itself only during operation. Alas, but this also happens.

Marriage in the form of loose screws

No matter how paradoxical it may sound, but such a type of marriage as an unscrewed screw is a fairly common thing in plastic windows. Moreover, despite its harmlessness, it can bring a lot of trouble. Over time, the double-glazed window can move, rest against the same screw, self-tapping screw, anchor, and gradually begin to crack. As a result, the crack will reach the middle, and the owners will be perplexed why the glass in the double-glazed window burst.

A double-glazed window burst from the heat or for some other reason absolutely does not matter. Another thing is important - after a crack formed on it, the window ceased to perform the functions that were assigned to it. Plus, the aesthetic appearance began to be desired. Can something be done about it? Of course. With this question, you can contact our specialist, who will tell you in detail how and in what direction you need to move.

If the glass in the double-glazed window is cracked at the plastic window, then do not despair. Such damage can be repaired. If you contact a specialist, the work will be carried out as soon as possible. In winter, this damage should be given special attention, since cold air will penetrate into the room, ice may form on the glass. At the same time, it is worth considering that during the work itself in the house, you will have to endure a drop in temperature for some time.

Cracks in glass panes can be caused by a variety of factors. The most commonplace is mechanical damage. Accidental impact may cause cracking.

The cause of damage may be improper installation of the plastic window. If, during window assembly, the double-glazed window was installed incorrectly in the frame, with an offset, then this can lead to excessive load. This, in turn, leads to the appearance of cracks. Also, if the frame itself, when installed in the window opening, was installed crookedly, this may cause damage.

If the glass in a plastic window bursts, then thermal shock can cause damage. This phenomenon is observed in the case of uneven heating of the glass in the case of a sharp temperature drop. The difference in pressure can also lead to glass cracking.

If you close and open the window with strong pressure, constantly slamming, then this also leads to a decrease in the strength of the glass, up to its cracking. Therefore, careful attitude to the design is important.
