What to do if cracks appear in the double-glazed window. Cracked plastic window: causes, repair

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

There can be several reasons for the appearance of cracks in window glass. 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. A very important point: the lining should 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 step is the installation of glazing beads, which is done in the 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 completed in full form, that is, it must contain the details of the defendant, the name of the applicant, date, basic 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, 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.

Causes of cracks

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.

How to properly install a plastic window, read the article Installation of plastic windows: tips and tricks.

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 event 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.

Only the master can determine the exact cause (with the exception of mechanical damage). 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

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

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.
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 severe frosts, this can lead to strong 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 with a small defect it is quite acceptable. And the winter will allow you to survive completely with a comfortable indoor temperature.

For more information about the design of plastic windows and its elements, read the article How to choose the design of a plastic window.

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 heat the window too much, direct hot air at it. For example, if work is carried out with a 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.

Thus, repairing cracked glass in the winter is not only possible, but also necessary. Decide which repair option is best suited and with the involvement of what forces it will be carried out, independently or with the help of qualified specialists.

What to do if there is a crack in the window

A double-glazed window is a separate part of a 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 causes of glass cracks:

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 can occur if in the winter season, with a minus on the windowsill, an electric kettle boils, thereby artificially obtaining a large temperature difference on different sides of the 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 ended. 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 moist air got into it and the window will no longer fully fulfill 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 incorrectly calculated the required amount of 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 there is high humidity in the room, then this can also cause 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 mounting foam, or by dismantling the window. 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 you find bubbles in the installed window, 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 the 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 the "leopard skin" of tempered windows, visible at a certain sharp angle, are 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 technological processes in the manufacture of double-glazed windows are violated. 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.

Your apartment has brand new plastic windows that please with reliable thermal protection, functionality and attractiveness. But suddenly an annoying crack can appear in the glass. Why did the glass pane burst? Let's try to figure this out.

Double-glazed windows are made in industrial conditions. At the moment of sealing, the atmospheric pressure and the pressure of the gas enclosed between the panes are equal. But atmospheric pressure tends to change. When a significant difference in external and internal parameters occurs, mechanical stresses arise in the glass and they are maintained until the difference in internal and external pressures is maintained. Mechanical stresses lead to glass deflection. Both panes can bend outward, or bend inward. The direction of deflection depends on which side the air load is higher on. The edges of the glasses are fixed with a sealant, which prevents the stabilization of the atmospheric load. The bending of the glass increases, reaches a critical...

You have installed new PVC windows and cannot get enough of their attractive appearance and comfortable temperature in the apartment. However, here, to your great annoyance, you find a crack on the glass. Why can glass in double-glazed plastic windows crack? There may be several reasons.

How can temperature fluctuations hurt?

Unstable temperature conditions can adversely affect the condition of the windows. In clear weather, the double-glazed window heats up under the influence of direct sunlight. The air in its inner part also becomes hot, its pressure increases, so it begins to exert pressure on the glass from the inside. If the temperature outside the window has dropped sharply, quite the opposite happens. That is, the glass bends inward or outward. Temperature fluctuations sometimes compensate each other, but often only aggravate the situation and overlap each other. For example, at low atmospheric pressure on hot days (that is, during summer cyclones) and at high pressure ...

Cracked, and even more so broken window glass, sometimes causes a strong shock. After all, many questions inevitably arise: why did this happen, how much will the replacement cost, where to look for a new double-glazed window, who will rearrange?

Causes of cracks
Glass can be damaged as a result of mechanical impact from the outside or due to processes occurring inside the window chambers. For example, as a result of being hit by a heavy object or being exposed to natural disasters.

In the second, the reason for the violation of the integrity of the glass lies in the fluctuations in internal voltage, especially in winter, when the temperature is negative outside, and indoors with a plus sign.

Window replacement is required not only from an aesthetic point of view, but also from a practical one, because cracks in the glass contribute to heat loss.

Of course, glass should not burst, but it happens. If your glass breaks immediately after installation, and even a lot, then this is a consequence of improper installation. The first main reason for this is the frame is crooked, with blockages (screw) or the frame itself with bends. Perhaps the support pads were installed incorrectly or they were not installed at all. Fasteners can stick out and interfere. Maybe some self-tapping screw or a foreign object remained on the frame and interferes with the glass. Perhaps they were simply not careful when handling double-glazed windows and made chips on the edges of the glasses. Perhaps the cutting of glass is of poor quality and there were microcracks on the glasses and now they have shown themselves. If a double-glazed window is in a balcony door, slow-witted installers sometimes use too long self-tapping screws when screwing the balcony handle. It is possible that the cause of the broken double-glazed window could be the state of "sticky glasses". This is when the air pressure inside the double-glazed window is much less than atmospheric pressure and at the same time increases ...

Cracks on the plastic window - how to deal with them

Plastic windows are indispensable where they want to create coziness, silence, comfort. But every thing has its own lifespan. And plastic windows are no exception. Ideally, they can last up to 50 years. In practice, a rare design will last a given period without repair. When certain defects of plastic windows arise, the question arises: can it be repaired, or is it necessary to change it completely? Many malfunctions of plastic windows can be fixed independently.

One of the common defects of plastic windows is cracked frames. A crack most often appears when there are violations of the production and installation technology. The window brought for installation must be carefully inspected for cracks, chips and scratches. However, not every defect can be detected immediately, sometimes cracks may appear only some time after installation.

What to do if the glass in the double-glazed window is cracked / broken / burst? It is necessary to replace the glass in the double-glazed window (or, easier, just replace the double-glazed window). We will tell you how to properly replace the glass in a double-glazed window if it burst.

Double-glazed window design

A double-glazed window consists of several panes attached hermetically to each other. Inside the space between them contains an inert gas or dried air. This protects the double-glazed window from condensation and fogging. For better absorption of moisture, silica gel is also filled inside the double-glazed window. Therefore, it is recommended that if cracks occur on one of the glasses, the entire double-glazed window should be replaced. Otherwise, when the double-glazed window is depressurized, silica gel begins to take moisture from the air, and when the glass is glued, it releases it, forming water droplets.

The photo is too small to understand.

Double-glazed windows in blind parts and in sashes are installed differently (as gofra already said), I am enclosing a diagram.
If the double-glazed window is fixed in the sash in a different way, then its geometry will suffer (the rectangle will turn into a trapezoid) and the double-glazed window becomes a load-bearing element. Here is a possible reason for you.
Reason #2:
Are you saying the frame is warped? This is a montage defect. If the frame is a screw, then the sash, pressing against it, also bends - the glass twists and it bursts. Here's another possible reason for you.
P.S. Heating has nothing to do with it, unless, of course, you aimed a cannon directly at the glass from half a meter.
P.P.S. You can try to loosen or remove the fasteners from the side of the hinges. It will stand "on the foam" for some time, and then, if it does not crack, fix it again.

It is worth immediately clarifying that replacing broken glass in a plastic window most often comes down to replacing a double-glazed window. The problem is that all glass sheets are connected using sealants, therefore, it is possible to replace one glass and at the same time ensure the required level of sealing of the double-glazed window only in the factory. And it will eventually come out not much cheaper, but it will take a lot of time.

Therefore, even if one glass is broken, it is possible without dismantling the old glass unit. order a new one from the same company. The main thing is to correctly measure and determine the type of new double-glazed window.

The fact is that replacing broken glass in a plastic window can even be beneficial for the consumer. Why not use this unpleasant situation to increase the level of thermal protection of the window? For example, if the profile width allows, then two-chamber stacks can be replaced with three-chamber ones.

Another option is to replace double-glazed windows with ordinary glass with energy-saving ones, which will reduce heat loss ...

Why do double-glazed windows burst. Causes and Prevention

Today, a double-glazed window installed in the window opening of an apartment will not surprise anyone. This product, due to the presence of glass in it, is the most fragile element of the window structure. Rarely, but still it happens that the double-glazed window becomes unusable. Its glass cracks or, worse, breaks.
Why this happens, what actions need to be taken, if the installed double-glazed window, which has been pleasing to the eye for a long time, has burst, we will describe in this article.

The main reasons for the appearance of cracks.

Short-term mechanical impact on glass. Simply put, hit. The sharp closing of the window sash, which caused a change in its geometry. Errors when installing double-glazed windows. As you know, all windows are installed in accordance with GOST, so any deviation from building codes can be a decisive factor, which is why a double-glazed window may burst. Influence of weather...

There is a crack on the window glass, and glass replacement is not yet in your plans? Do not despair, everyone can fix a crack on a window glass.

Preparatory work

You should start with a thorough washing of both surfaces of the glass, fortunately, there are more than enough all kinds of detergents on sale. Just remember to wear rubber protective gloves, as the detergent is a rather aggressive thing. And since the washing solution is ready, wash the glass in the rest of the windows at the same time. When dirt and dust are removed from the glass surface, all that remains is to wipe its surface dry.

It is very important that not a gram of moisture remains in the crack, otherwise all the work of sealing the crack will be in vain. Let the water evaporate naturally, or use a hair dryer to dry the cracks at minimum power. You can speed up the drying of moisture by directing a stream of air from a domestic fan onto the glass.

Cracked glass on a plastic window. Who is to blame and what to do?

If a crack on a double-glazed window went from the edge of the double-glazed window from the glazing bead or the inner glass in the double-glazed window cracked, then this could happen for two reasons:
1. Glazing was not done correctly

2. During the installation of the window, the geometry of the window was violated. Either the anchors were pulled hard, or there was too much mounting foam, which squeezed out the frame.

Either way, it's the window company's fault. The law establishes a minimum warranty period for windows - 3 years. If this period has not passed or the warranty period under the contract is longer and it has not yet expired, then contact the window company that installed the windows for you - double-glazed windows ...

Author Topic: Cracked double glazing (Read 44325 times)

Hello! You should check the plane of the plastic window frame, whether the corners correspond normally, whether they are skewed inward or outward. Since the glazing beads on the PVC window are tightly pressed to the glass, the double-glazed window can "stretch" behind the frame. If the glass of a plastic window deforms even a little, a crack is inevitable. Recorded by

Same story! PVC windows were just installed yesterday. After installing a balcony block in a triple-glazed window, the outer glass burst on the outside of the door. A crack on the PVC window goes from the handle to the width of the door and another crack is shorter. The most interesting thing is that even the installation of PVC windows has not yet been completed. I wrote in the coupon: a double-glazed window burst during installation, they promised to replace everything, so I'm waiting ... A good double-glazed window cannot burst !!!

Broken glass in double glazing

If the double-glazed window burst - it can only be replaced. Unfortunately, it is not possible to glue broken glass.

If a double-glazed window is cracked, then the cause of this can be either a factory defect or any external influences.

If the glass in a double-glazed window is cracked due to the fact that the window was poorly assembled at the factory, then this will manifest itself in the very first days of operation. As a rule, the warranty is still valid at this time and the double-glazed window will be changed without any problems for free.

If the double-glazed window is broken due to the fact that someone broke it, then it will have to be replaced at your own expense. What to do if a double-glazed window is cracked is briefly described below.

If the glass in the double-glazed window is cracked, there are three ways to do it:

Answer

Hello,

There may be several reasons why a double-glazed window may crack:
1. Most likely, when fixing the glazing bead, the nail came out, touching the edge of the glass. After installing the window in this case, a crack sometimes forms.
2. Marriage of glass, there was a chip at the end when installing a double-glazed window, after a while, as a result of external influences, a crack went from it.
3. The double-glazed window is installed incorrectly, see GOST 24700-99, clause 5.5. Requirements for component parts and their installation, and GOST 30674-99, clause 5.6. Requirements for glazing, door leaf panels and gaskets, Figure 5
4. Check the plane of the frame and see if one of the corners is pulled in or out. The glazing beads usually press the double-glazed window tightly, and it can take the form of a frame. In this case, the slightest deformation inside the glass is enough and a crack is formed.
5. External impact on glass - impact (including acoustic), temperature impact (both high and very low ...

Reasons for glass damage

Sometimes poor-quality production of a double-glazed window becomes the reason that it has to be changed. How to choose glass so that the replacement of double-glazed windows in plastic windows with your own hands is of high quality. Even if only one glass is damaged, the entire glass unit must be replaced.

There can be several reasons for cracked glass.

Incorrect installation of the entire window in violation of the geometry (gaps are violated, gaskets are missing or displaced, mounting foam is applied incorrectly, etc.). Incorrect measurement during its manufacture or incorrect installation can only affect after a few months. The internal stress in the window eventually causes the glass to crack. The result of the appearance of cracks can be its improper storage during the manufacturing process, atmospheric pressure drop. It is possible to press the sash incorrectly when closing the window, unintentionally violating its geometry and ...

The glass of a plastic window is damaged - causes and actions

Causes of glass cracks

There can be several reasons for the appearance of cracks in window glass. 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

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

The service is not of good quality - what to do

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 the inside.

One of the four parties may be to blame for the fact that the glass in the double-glazed window has burst. We are talking about the owner, the company that carried out the installation, the manufacturer of the metal-plastic structure, 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 of the window frame changes. 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 is especially true for 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 you can. With this question, you can contact our specialist, who will tell you in detail how and in what direction you need to move.

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

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

Cracked Glass Repair

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

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.
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.

If you have a small crack, then you can live the winter with a cracked double-glazed window. A small crack can simply be sealed with transparent tape. This method is short-lived, but with a small defect it is quite acceptable. And the winter will allow you to survive completely with a comfortable indoor temperature.

Damage prevention

You can not heat the window too much, direct hot air at it. For example, if work is carried out with a building hair dryer, then contact with glass should be avoided.
