At first glance, the construction of a plastic Euro window seems complicated. Therefore, if the glass unit as a whole or one of the glasses is damaged, many immediately look for the phone number of the repair companies. In this situation, there is no need to rush: replace the glass unit in plastic window you can do it yourself, thereby saving several thousand rubles.

A double-glazed window is a complex sealed structure consisting of several sheets of glass, separated from each other by an aluminum frame, under which silica gel balls are poured - they absorb moisture in the bag chamber. Between the glasses, a double sealing is installed from butyl tape located under the spacer frame, and thiokol - a special mastic that connects the entire structure into one whole.

For reference: you can read more about the insulating glass unit in the work "".

This system has very weakness- glass. The material is very fragile, capable of cracking or breaking at any time. If this happens, it is necessary to immediately replace the glass in the double-glazed window, since due to the depressurization of one chamber, not only the package, but also the window as a whole, rather quickly loses its consumer properties:

• moisture appears on the glasses, and the desiccant flows down in the form of a yellow resin;
• street sounds are clearly audible;
• drafts appear;
• poorly retained heat.

In addition, replacement of a double-glazed window is required in cases when:

• the bag chamber has lost its tightness (the reasons may be different), and therefore the glass sweats in summer and becomes covered with frost in winter;
• it is necessary to insulate the room, as a result, ordinary fload glass is changed to i-glass or a single-chamber package to a two-chamber one;
• the sounds of a noisy street began to penetrate into the room - soundproof double-glazed windows are being installed.

Is it possible to replace glass in a glass unit

The most frequently asked question when contacting a company for the installation and repair of double-glazed windows: "Is it possible to replace broken glass in a double-glazed window without changing the latter?" Depending on the level of the company, there may be several answers: "No", "Yes", "It is possible, while visiting the customer."

Let's take a closer look at each of the answers.

"No" say in a reputable firm. They value their reputation and offer the client the best option: dismantling the broken package and installing a new one.

"Yes" can be heard from people seeking to make the most of their money. They will come, remove the window, bring it to the workshop, where they will remove the damaged glass and install a new one. After that, the repaired glass unit will be brought and installed in place. There are no questions about the quality characteristics of such a repair - everything was done in accordance with the technical regulations.

Questions arise about the cost of repair work (meaning only the replacement of glass in the package itself) - they are for 100-200 rubles. more expensive than a new glass unit. Plus, the glass unit will be installed by the company that made the repair, and this is an additional 2,000 to 4,200 rubles per m2. Therefore, it is better for apartment owners to refuse such a service with their hands (the recommendation does not apply to those who are not used to counting money).

"You can, while visiting the customer." This glass replacement should be briefly described: knee repair. For those who like to learn from their own mistakes, at the end of the work we will give detailed instructions such a replacement with your own hands.

Why is glass in a glass unit not being replaced at home? After all, it is not difficult to remove the glass unit from the sash, cut the mastic around the damaged glass with a sharp knife, remove the fragments and clean the camera from dust and dirt.

There are no difficulties when cutting new glass to fit the spacer frame. Indeed, there are no problems here. They lie in a different plane: at home it is impossible to recreate the technological conditions for assembling a double-glazed window: dry, warm air, while without dust when sealing the entire structure.

When sealing outside the chamber, it will not work:

• thoroughly wash and dry the glass so that the smallest debris does not fall on it during drying;
• keep the silica gel in working order - its balls will have time to pick up moisture from the air in a short period of time (the air in the chamber is dry);
• apply the mastic in an even layer, as a result of which, when the package is installed in the window sash, the sealant may be damaged;
• Thiokol is difficult to find on sale in compact packages - mainly in two-hundred-liter barrels.

In what cases is it permissible to replace only one glass

• There is stained glass in the window. Replacing one sheet is much cheaper than replacing several expensive glasses;
• A three- or four-chamber package is mounted in the frame;
• An expensive thick triplex is installed in the sash from the street, and the inner glass is broken.

In the above cases, the cost of repairs is cheaper than the price of a finished glass unit.

Instructions for replacing a double-glazed window

For those who are friends with tools, self-replacement of a glass unit in a plastic window is not an insoluble problem. The whole process consists of several sequential operations:

1. a set of tools is being prepared;
2. the glass unit is measured;
3. an order is made;
4. the damaged glass unit is dismantled;
5. new glasses are installed;
6. the sash is adjusted.

Tools and materials

Replacing a broken glass unit is carried out with a minimum of tools. Looking for:

• roulette;
• calipers;
• rubber hammer (mallet);
• a spatula or a simple screwdriver (you can also use a large kitchen knife, but this is not very convenient);
• gloves;
• an old sheet or piece of other fabric that you do not mind throwing away.

Measurement

To order a double-glazed unit, you must specify the number of air chambers and the dimensions of the glass unit: height, width and thickness. All these data can be found on the spacer (see photo), where the package formula (quantity and thickness of each glass) and its dimensions (height, length and thickness) are printed. If for some reason such an inscription could not be found, the owner himself can make the measurements.

Important: the simplest option is to remove the glass unit and measure it. But with such an organization of work, the window will stand without glass for several days - it takes time to make a new double-glazed unit. Therefore, measurements are taken directly in the sash.

To measure, a tape measure is taken and the distance between the profile of the sash with broken glass is measured along the width and height of the window. A number of publications say that the distance between the external dimensions of the glazing beads is measured, which is the same thing. From the results obtained, 2 cm is subtracted - 1.0 cm on each side for the adjustment gap.

An important parameter is the glass unit formula, where the thickness of each glass and the distance between them inside the chamber are indicated (for example, 4 + 10 + 4 + 10 + 4, where 4 is the glass thickness in mm, 10 is the width of the frame in mm). These numbers must be prescribed in the passport of the window and printed on the distance bar. If the passport is lost, but there is no inscription, you can carry out an independent measurement. A tape measure gives an error of up to 1 mm, a vernier caliper measures with absolute accuracy. Work order:

1. The thickness of the sash profile is measured (eg 70 mm);
2. The thickness of the glazing bead and the rubber seal (located inside the room) is determined. For this end measuring tool rests against the glass and looks at what distance the sash plane is (approximately 14 mm);
3. A similar procedure is carried out from the street side (20 mm).

The rest is within the power of a second-grade student: from 70 we sequentially subtract 14, and then 20. The result of 36 mm will enable specialists to draw up a formula for a double-glazed window and use it to make new glass.

Order

For the manufacture of a double-glazed window with angles of 90 o, it is enough to indicate in the application form the thickness of the package, its height and width, as well as the number of chambers. The manufacturer's specialists will independently calculate the formula and use it to make new glass for the window. Everything is much more complicated if there are curvilinear shapes or non-rectangular corners (glass in the form of a circle, triangle, rhombus, etc.). How to change the glass unit in this case?

Here you cannot do without dismantling the damaged glass (how to do this, just below). Removed glass stacked on a drawing paper and outlined, after which the shape of the damaged bag is cut out with scissors. Sometimes the template is cut immediately with a razor blade. A new double-glazed unit will be manufactured according to the finished template within a few days.

Dismantling

There is nothing complicated in the instructions for dismantling a broken glass unit. The whole process consists of a series of sequential operations:

1. On the floor in front of the window, an old sheet or other fabric is spread, large in size behind a double-glazed window.
2. The broken glass is carefully glued in several directions with tape so that the fragments do not fall out during the removal of the package and cause injuries to others.
3. Glazing beads are removed. This requires a sharp and tough tool such as a chisel, flat screwdriver or spatula, and a mallet (rubber mallet). It is necessary to start with longer glazing beads, as a rule, lateral ones - it is easier to bend them when removing them from the sash grooves.

Attention: almost all instructions for dismantling double-glazed windows indicate that disassembling the sash must begin with removing the side glazing beads. However, they cannot be removed in the transom without damage. Therefore, we focus on the fact that initially longer glazing beads are removed - in the transom, these are the top and bottom.

To remove the glazing bead, you should:

• Insert a spatula (chisel or screwdriver) into the gap between the sash profile and the glazing bead in the middle of the window;
• Holding the tool strictly horizontally, hit it several times, not very hard, with a mallet until a gap of 1-2 mm is formed. Further, the technology differs slightly for different specialists; Some make such a gap almost along the entire length, and then return to the middle, others, immediately tilting the tool down, knock the glazing bead completely out of the grooves of the sash in its center;
• When you can grab the glazing bead with your fingers, it stretches towards itself and to the side - it will easily come out;

Important: when removing the glazing bead with a pencil or marker, it is necessary to mark the grooves on the sash in order to install a new double-glazed window without any problems, especially when changing its thickness (you will have to buy new glazing beads and cut them correctly).

• The upper latch is removed last - protects the glass from accidental fall. An assistant is needed to support the glass;
• The bag is removed from the sash. If difficulties arise - the sealant of the package is glued to the plastic of the window, the glass is squeezed out of the frame with a sharp object;
• The removed bag is placed on the fabric and gently broken;
• The broken glass in the sheet is thrown into the trash can.

Installing new glass

The installation of a new glass involves the following operations:

• The fastening of the seal from the outside of the window is checked;
• Straightening plates (also called gaskets) are installed in the fold of the sash: two at the bottom for a blind window (see photo), four for an opening sash. At the same time, they are installed, one on each side, diagonally, at a distance of about 10 cm from the corner of the sash (see photo).

Attention: the number of strips from different manufacturers may differ, therefore, when dismantling the glass, it is necessary to remember the location of the gaskets.

For reference: the rebate is a plane along the perimeter of the sash, on which the glass unit is mounted, which is clearly visible in the photo.

• The insulating glass unit is neatly placed on the gaskets. Here it is necessary to check its position several times, since it will not be possible to correct the geometry later;
• A seal is installed on the inside of the glass unit;
• Glazing beads return to their places in the reverse order: first the upper, then the lower, and only then the side ones. They are driven into the grooves by lightly tapping a rubber hammer from the edges to the center. The fixation is confirmed with clicks.

Adjustment

The new glass unit may have a different weight, which will require additional adjustment of the sash. To do this, use the "furniture key" to tighten the adjusting screws on the hinges, which can be read in detail in the material "How to adjust plastic windows".

The nuances of replacing a double-glazed window in a wooden frame

The wooden frame of the euro-window is fixed with a double-glazed window in the same way as in a plastic window - glazing beads. However, there is a small difference: instead of a rubber seal, a silicone sealant is used.

Therefore, in order to remove the glass from the wooden sash, you first need to remove the glazing beads, and then remove the silicone mastic. Accordingly, when installing a new glass, it is necessary to re-treat the joints of the package with the sash with silicone.

The nuances of replacing a double-glazed window in stained glass

There are several points in stained glass windows that do not allow DIY repair and replacement of damaged glass:

• It is much cheaper to replace broken glass than to install a new package, and such work can only be performed by professionals in a specialized workshop;
• The glass is placed in special "stained-glass cells", which are removed outside, and not inside, which requires an aerial platform or the installation of scaffolding;
• Remove the pattern by colors impossible. It is necessary to deliver the whole glass to the workshop, where the necessary measurements will be carried out with the help of instruments, on the basis of which the glass is reproduced.

Can I change

When replacing a damaged glass unit, in many cases it becomes possible to change the number of chambers in it.

Single-chamber double-glazed window for two-chamber

Replacing a single-chamber window glazing with a two-chamber window is possible if two conditions are met:

1. The sash rebate width allows the installation of a double-glazed unit. There are two options here:

1. a package of three glasses is the same in width as a single-chamber one - no problems arise;
2. the new package is wider, but due to the narrower glazing bead (you will have to buy new ones), it fits into the sash.

2. The profile and fittings of the window support the weight of the heavier sash (increases by about 30%). If it is necessary to reinforce the reinforcing plate inside the profile, it is easier to change the entire window. If the problem is only in the loops, they change.

Therefore, without consulting a specialist, it is not recommended to carry out such a replacement on your own.

Double-glazed window for three-chamber

A triple glass unit is installed instead of a two-chamber unit under the same conditions as given above. The only difference is that the three-chamber package is only 25% heavier than the two-chamber package, which in many cases does not require reinforcement of the frame profile.

Instructions for replacing glass in a glass unit yourself

For those who like to do everything on their own, we will give instructions on how to change the glass in a glass unit at home.

For work you will need:

• glass;
• butyl tape;
• silicone based sealant;
• chisel;
• rubber hammer;
• acetone (any other solvent);
• construction gun;
• diamond glass cutter.

The work algorithm is as follows:

1. A double-glazed unit is removed from the window block (you can see how it is done above) and placed on a flat surface with the damaged glass upwards;
2. With the help of a chisel or a knife, the broken glass is removed from the package, after which the aluminum frame is cleaned of sealant and debris;
3. The cleaned places are degreased with a solvent;
4. New glass is cut;
5. The newly cut glass is washed and dried with warm air. The same operation is carried out with the glass surface where degreasing was carried out;
6. A layer of sealant is applied to the frame of the package with a gun, after which a new glass is laid. You need to lay it with a partner and immediately for sure. It will be very difficult to fix;
7. An absorbent is poured under the spacer;
8. The package is sealed along the perimeter of the glass;
9. After the sealant has hardened, the glass unit is placed in the sash.

We emphasize once again: "repair on the knee" does not give a long-term effect. The best option is to replace the glass unit.

How much is the service in organizations

The final price of the work is determined by many factors. Therefore, we present the average lower and upper limits of the price lists of several firms in St. Petersburg and Moscow as of December 15, 2018:

• Replacement of a double-glazed window unit - 2,000-4,200 rubles / m2 (delivery is included);
• Repair of a double-glazed window - from 1,000 rubles / m2 to 2,300 rubles / m2 - only work. Transportation and glass costs are not included here.

For reference: the cost of a new double-glazed unit starts from 1,300 rubles / m2 from little-known companies. For recognizable brands, it starts from 2,050 rubles / m2.

Conclusion

Window glass tends to break. It also beats in double-glazed windows. In this case, the most rational is:

• replacement of not a separate glass, but a glass unit as a whole;
• dismantling and installing a new package on your own - family finances are saved.

It is possible to replace broken glass at home. But such work gives an effect for a very short time - at home it is impossible to recreate the conditions of the chamber in which the glass units are being assembled.

Profile systems are completed with removable glazing beads, allowing partial disassembly of the window structure. Thanks to this, it is possible at any time to install a model with improved characteristics in the window if it is damaged or if it becomes necessary. Such repairs are much easier and more economical than replacing the entire structure, which is often not particularly necessary. The possibility of replacement is provided for all types of windows from any profile systems - plastic, aluminum and wood. The very process of removing the old glass unit and installing a new one does not take much time and does not require a complete dismantling of the window block or sash.

In what cases is it possible and advisable to replace a double-glazed window

It is beneficial for window manufacturers that people who turn to them for help replace the entire structure. However, such a need arises in the event of a serious violation of the original geometry of the frame shapes or significant damage to the profile.

Most often, this is observed:

• with a significant subsidence of the foundation;
• due to violation load-bearing structures on the lower floors;
• due to a hacking attempt;
• due to an explosion both indoors and outdoors.

Usually, in such cases, specialists visit the site and assess the condition of the frames and profile. If the glass is broken as a result of the impact, then the task is greatly simplified - in this situation, the frames most often retain the same geometry, and it is enough to replace it.

Replacement of double-glazed windows is carried out not only due to their mechanical damage, and in some cases, window owners are no longer satisfied with the level of heat or sound insulation of these products. In such situations, it is most practical to limit yourself to replacing the double-glazed windows.

Is it possible to change one glass in a double-glazed window

Some window owners, in an effort to save money, want to limit themselves to minimal repairs. In the case of mechanical damage that does not have a through nature, they are interested in how possible it is to replace glass in a glass unit? Basically, there is a working way to accomplish this procedure. However, when performing such a service by hired specialists, it is more profitable to replace the entire glass unit. This is due to the fact that the technology for installing new glass is quite laborious, and professionals will include the time spent in the bill.

Replacing single-chamber double-glazed windows with two-chamber

If the thickness of double-glazed windows with one and two cameras is the same, then there are no obstacles to replacing one model with another. Even in cases where they are thicker than single-chamber, the possibility of their installation is allowed. If the dimensions of the profile allow such a replacement, the purchase of new glazing beads, which are thinner than the previous ones, is required.

It should be borne in mind that double-glazed windows are at least 40% heavier than single-chamber ones. The difference in weight is especially relevant for large glazing areas. As a result, it is recommended to scrupulously check the structure for its ability to withstand a significant mass before replacing it. Probably, it may be necessary to reinforce the frames, and for the sashes - replacement of the hinges.

How to replace a broken glass unit

This procedure can be performed on your own, but it is better to entrust it to a professional. Double-glazed windows have a decent weight and are fragile structures. Any careless action made out of inexperience can cause defects. Moreover, there will be plenty of opportunities to damage a new product during self-replacement, since replacing a broken glass unit consists of several stages:

For specialists, this whole procedure is not a problem, since they have repeatedly performed it. And people who do not have practical skills may experience complications at each of the mentioned stages.

Alternative to replacing double-glazed windows

To increase the level of heat and sound insulation, as well as improve the sun-protection properties or aesthetics of windows, you can use special films that are glued to the glass from the side indoor spaces... Today, universal polymer coatings are popular, which trap the incoming UF radiation from the outside and do not let heat out of the rooms. More about

Replacing a double-glazed window is not a big deal, the main thing is to know a few basic rules on how to replace a double-glazed window in plastic windows on your own.

Replacing the glass unit may be required if the window is damaged.

Of course, you can invite an experienced specialist who will provide qualified assistance in replacing a double-glazed window.

However, it is necessary to pay a certain amount of money for the services of a specialist, so you can save money and change the glass unit yourself.

In general, the replacement process is divided into three stages:

• taking measurements of the old double-glazed window;
• removal of the old glass unit and its constituent elements:
• installation of a new glass unit and its constituent elements.

Let's consider all the stages in more detail.

Measurements and dismantling of the old glass unit

There is an opinion that in order to measure the old glass unit of plastic windows, it must be pulled out of the opening, but in reality everything is different. You can take measurements without removing the structure.

To do this, you need to measure the distance between the glazing beads, which will serve as the basis for all calculations. It is necessary to measure the width and height of the glass unit. Subtract 1.5 cm from each value.

The numbers obtained are ready-made sizes... Now you can proceed to removing the old glass unit.

To remove the old glass unit, you will need the following tools:

• plastic hammer, mallet;
• chisel;
• putty knife;
• special curved knife for silicone sealant;
• pencil;
• roulette.

Dismantling the old package begins with detaching the glass unit from window frame, by removing glazing beads. To do this, insert the corner of the chisel into the space between the frame and the glazing bead.

With the tool tilted to the frame, tap the handle of the tool lightly, increasing the space between the frame and the glazing bead.

It is required to take into account that the sting of the chisel with a sharpened edge must be positioned in the direction from the window. You need to knock on the glazing bead until it comes out of the groove. Then the tool is removed.

First, the left glazing bead is removed, then the right one, then the lower one, and the top one is always removed last. Thanks to this order, the window will not fall out of the frame.

Also, if there are retaining nails on the frame, they must be carefully pulled out.

It is better to pull out the window together, or you can use special suction cups that hold the glass well.

Sealing elastic bands between the glass unit and the seam window profile, they are also called bridges, must be carefully assembled and also marked for subsequent installation in their place.

The gasket provides adjustment of the glass unit, adding rigidity.

Installation of a new glass unit

When the old glass unit has been dismantled, you can proceed to installing a new one. First you need to inspect the window frame for dust and dirt.

Existing dust can be removed with a brush, and grease on the rebate is removed with a narrow spatula.

At the first stage of installation, rubber bands are placed on the frame in a specific sequence. The sealant fixes the glass unit inside the window.

Also, the sealant protects plastic windows from drafts, frost penetration, condensation. Then you need to install a double-glazed window.

Before the final installation of glazing beads, it is necessary to make sure that the seal is firmly pressed against the glass unit, and the sealing rubber bands are completely invisible, because peeping rubber bands indicate a violation of the geometry of the window.

Glazing beads are installed in reverse order: first vertical, then lower and upper.

You can slam the glazing beads with a plastic hammer with gentle movements. First you need to install one corner of the glazing bead, then the second, after that the glazing should bend slightly.

You need to lightly hit the central part with a hammer, and the glazing bead will snap into place.

It should be noted that the glass unit is not inserted too tightly, as this can provoke cracking when the temperature changes.

Thus, you can cope with the replacement of a double-glazed window in a plastic frame on your own, the main thing is to perform all actions with care and accuracy. Detailed process replacements are presented in the video in the article.

Replacement and installation of constituent elements

The construction of a plastic window consists of several additional elements, which may also require repair or replacement.

Installation of the window sill

When the frame and glass unit are installed, the window sill can be installed. First of all, the measurement is taken. First, the width of the window opening is measured.

You need to add 10 cm to the resulting figure and you get the length of the finished window sill. The width corresponds to the distance from the window to the corner of the wall, to which is added 5 cm.

It is necessary to prepare a support for the window sill; for this, substrates are used. The width of the substrate bars should not exceed 5 cm, and the length should not exceed the length of the window sill.

The thickness of the bars must be chosen so that the window sill fits into the space between the frame and the substrate. Before installing the blocks, you need to level the base with cement.

The bars should be spaced in 45 cm increments.

The supports must be horizontally aligned, then check compatibility by inserting a window sill. Finally, the sill is installed after removing the protective film from the panel.

The window sill is equipped with plugs from the ends. Next, the window sill is installed on the supports with neat movements. The side gaps are filled with sealant.

In the central part and on the sides, you need to place spacers that prevent the base from lifting, which you can do yourself or buy in a store. After that, the remaining gaps are filled.

Replacing the handle

Let's take a look at how to install or replace a handle.

In the event of a breakdown, first you need to eliminate the cause of the defect, and then adjust the handle. For this, the plate covering the fasteners is rotated 90 °.

If you need to tighten the handle, then just tighten the screws with a screwdriver.

If the handle needs to be replaced, then you must first unscrew the screws, and then remove the handle.

It takes 15 minutes to repair or replace the handle.

Installation of a mosquito net

Now, if necessary, you can install a mosquito net for a plastic window.

A mosquito net is installed to prevent insects from entering the room, as well as from excessive dust from the street. It is better to mount the mosquito net on aluminum brackets.

To remove the old mosquito net, you need to disconnect the rubber cord. Now the new mesh must be attached to the profile with the same rubber cord.

The cord is fixed with a blunt object, everything must be done carefully. The mesh protruding beyond the edges of the profile must be cut off. After that, the structure is installed on a plastic window.

When inserting the mesh into the window frame, you must be extremely careful, despite the fact that all actions are simple and easy to perform.

If the mesh is mounted for the first time, then a special fastener for the structure is attached to the open sash using self-tapping screws. The mount is fixed at the top and bottom of the window frame.

After that, the profile is exposed outward and firmly pressed by the special handles to the prepared strips.

The final stage of installing the mesh on the plastic window is to press the profile to the top of the window frame.

After that, the profile is wound over the lower bar, and the lower part of the mesh is lowered onto the mount. Then you need to check that the mesh does not wobble.

It is quite possible to replace the constituent elements of the glass unit on your own. All work on the installation of a double-glazed window and its components can be viewed in the video in our article.

Replacing a double-glazed window in plastic windows with your own hands is carried out in several stages. This is a simple operation, and if you follow all the recommendations, any person can handle it. Next, we will consider in detail the nuances of this procedure.

Before ordering a window from the manufacturer, you should find out what the varieties are. There are two classifications of double-glazed windows - according to the number of chambers and practical purpose.

The first classification includes the following categories:

• Single-chamber (consist of two glasses and one air chamber).

Note: the empty space must be filled with argon gas - it provides additional heat storage in the room. Ask about this when buying, as some manufacturers decide to save on this aspect.

• Two-chamber - three glasses and two air chambers.
• Three-chambered - four glasses and three air chambers.

The most popular variety today is two-chamber. Having an affordable cost, they provide excellent noise isolation (models with a single camera cannot boast of this). Three-camera options are too expensive - which is why they are not often sold.

Relatively design features there are 4 types of double-glazed windows:

• Plain (colorless).
• Energy saving.
• Toned.
• Multifunctional.

Now 70% of the market is occupied by energy-saving models. They are slightly more expensive than their regular counterparts. Their main advantage is additional heat preservation in the room. Therefore, we recommend opting for just such a variety.

Note that the need to replace the glass arises not only when it is completely damaged (which happens, by the way, quite rarely). If one of them has cracks, it is fraught with sad consequences (fogging, icing, etc.).

The main scope of work

What we need for work

First, prepare the following:

• New double-glazed window.
• Spatula or fine chisel.
• Plastic plates (specially designed for PVC windows).
• Other additional elements (linings, gaskets, etc. - depend on the manufacturer).
• Gloves and glasses.
• Rubber hammer.

Dismantling the old double-glazed window

First, we remove the damaged element. This is done in the following sequence:

• Place the trowel (chisel) between the glazing bead and the frame.
• Lightly hit it with a mallet. This will increase the gap between these elements.
• We take out the glazing bead. Such procedures will need to be repeated three times (for each side). When you get to the last glazing bead, hold the glass as it may fall out.
• Carefully remove the glass unit. We do this with gloves so as not to injure our hands.
• Having taken out the element, we take off its dimensions, according to which we order a new one. It is advisable to do this at the same company in which the PVC window was previously ordered.

If the need for replacement arises in winter and living for several hours (or even days) with a missing window is not an option, contact the company in which you ordered the windows in advance. They have precise measurements, according to which they will make new glass for you.

How to properly install a new glass unit

Replacing glass in a plastic window is carried out in the following sequence:

• We insert the straightening plates into the frames. In this case, an indent of 8-10 cm must be observed. Only the bottom plate can be installed on a regular frame (which does not open).
• For opening sashes, install the plates at two opposite corners (top next to the hinge and diagonally below). The use of these elements allows you to maintain the correct geometric location.

Please note: the number of planks differs from manufacturer to manufacturer.

All additional elements (pads, strips, rubber bands, etc.) must be ordered from the same manufacturer. This will avoid the trouble (which varies from supplier to supplier).

How to change glass in plastic windows? Is such a replacement of double-glazed windows possible on your own? How much will it cost? These questions worry many, because they always raise a lot of doubts. For some reason, people think that such work is impossible, but this is far from the case. Let's talk about how to replace double-glazed windows in plastic windows with our own hands.

Measurements

So there is only one The right way how to complete this task. It is necessary to take into account those points that are basic. Let's start with the main thing. Each window is special, its dimensions and shapes correspond to this particular opening, therefore, first of all, measurements must be taken. There are two ways here:

1. You can use an old glass unit, the measurements of which will be the basis for a new one and sent to the manufacturer in this form.
2. If this is not possible due to the fact that the glass is broken, then in this case three main indicators can be measured: length, width, thickness of the plastic window opening where the old glass unit was located. After that, you can transfer the required dimensions to a special organization that manufactures these products, and after a while pick up the finished product.

Now you can directly proceed to the installation, we strongly recommend that you turn to the help of a video before starting work, which will describe in detail the entire process of replacing a double-glazed window in plastic windows with your own hands. So you will not make mistakes and do everything as correctly as possible.

We remind you that you will need:

1. rubber hammer;
2. chisel or boot knife.
