Single-chamber with energy-saving coating 4M1-16Ar-I4 0.66
For large sashes, it makes sense to use single-chamber double-glazed windows with energy-saving coating. They will be lighter than two-chamber ones by almost 30%. The load on the fittings will be significantly reduced. By the way, a single-chamber double-glazed window with an energy-saving coating will be WARMER than a double-chamber one and cheaper. Here are the heat transfer resistance coefficients. The higher the coefficient, the better the thermal insulation:

The value of the number of chambers for a structure

Today, products with a large number of air layers are also offered on the market. Just as you can define a double-glazed window, these designs can be calculated by the number of glasses. For example, in a three-chamber room there will be four of them. Finding such products on sale is more difficult than the first two types. Not to mention the fact that there is a larger number of glasses in a double-glazed unit - in this case, most likely, you will need to negotiate on individual production.
Two-chamber without energy-saving coating 4M1-12-4M1-12-4M1 0.53
Double-glazed windows can be single-chamber (two glasses) and double-chamber (three glasses). Further increasing the number of glasses is not effective, since the price of the window and the weight of the sash increase, but at the same time the properties of the double-glazed window change slightly. To improve the thermal insulation properties of a double-glazed window, it is much more effective and cheaper to use energy-saving spraying.
The system is approximately the same as that of a two-chamber window. One of the cameras is expanded. To prevent the glass from “sweating” inside these cavities, a special substance is used.
Some call the glass or partitions themselves cameras - this is wrong! We take only the air space (some craftsmen, I heard, manage to pour foam inside the frame), which affects the level of thermal insulation.
There is already a nuance here - a three-chamber double-glazed window, as I understand it, is the peak. Everything that has four, five and six chambers is a profile, a frame, that is.
No. 8. Double-glazed windows and regional climate
When choosing a double-glazed window, first of all, it is necessary to proceed from the weather outside the window and personal requirements for the design. For warm regions, a single-chamber or single-chamber low-emission double-glazed window will be sufficient. In other cases, it is better to look towards two-chamber structures.
Each type of double-glazed window is characterized by its own heat transfer resistance indicator: for a regular single-chamber this indicator is at the level of 0.3-0.37 m2*C/W, and for a wide double-chamber it is already 0.5-0.62 m2*C/W. In order not to overpay, it is important to take into account the real needs for heat conservation . So, for example, for the Moscow region, according to building codes, it is better to use window blocks with a heat transfer resistance of at least 0.55 m2*C/W. This requirement is met by a two-chamber conventional double-glazed window and a single-chamber one with i-glass and argon filling.
In pursuit of a high-quality double-glazed window, do not forget about the profile : if it is thin, and there are cracks in the structure, then the house will still be cold and noisy.
What are the advantages of three-chamber windows?
The following regularity also applies - the more cameras, the higher the sound insulation.
If it were “direct fire”, then... These are the “safety precautions”. Morozov eventually ran to the pharmacy.
The upper wooden beam (about the same as in the photo, only longer) broke off and fell on the head of that Morozov’s partner, just struck (!) on the forehead, but the wound was impressive.
The sound is the same, even if I close the single-pane window in the bedroom and that’s it (nearby is a moderately busy street), I don’t hear anything.
The range of these elements of window structures is so huge that you can very easily get confused. For the production of double-glazed windows, spacers and glass of different thicknesses are used; their internal cavities can be filled with air or inert gas. In addition, for the manufacture of these products the following are used:
Expanding the range of wooden and plastic windows not only increases the possibilities of consumers, but sometimes also creates some difficulties for them. One of the most common problems occurs when buyers do not know which double-glazed window to choose - single-chamber or double-chamber. It is believed that the second option is superior to the first in all respects. This is true. However, is improved performance always necessary, and what price should you pay for it? Read about all this in our review.
No. 5. Type of filling of glass chambers
The glass chamber can be filled with one of the following gases:
- dehumidified air is the most common and most affordable option;
- argon has a higher dynamic viscosity and prevents convection between the glasses, so a double-glazed window filled with argon is approximately 1.4 times warmer than usual. In addition, argon protects the coating of i-glasses and is the best option in terms of price and quality;
- other inert gases, in particular krypton and xenon, have more outstanding thermal insulation properties and are “warmer” than air by 2.6 and 4.4 times, respectively, but such filling of chambers is very expensive, so it is not used today.
A promising direction is the production of double-glazed windows with a vacuum inside. Vacuum does not conduct heat at all, so it will provide maximum thermal insulation, but the production of such double-glazed windows has a number of technical difficulties, so it costs a pretty penny and is not widely used.
Double-glazed windows
Most well-known manufacturers of metal-plastic windows offer profiles with 3 to 6 air chambers. The best option is considered to be a profile with 3, 4 and 5 cameras. A smaller number of cameras does not comply with accepted sanitary standards and can only be installed in windows that perform a decorative function and are installed indoors.
What is a camera in a plastic window? We are not talking about cameras in a double-glazed window, but about cameras in the profile itself. Many manufacturers divide their profiles into profile systems precisely on this basis.
Checklist for assessing the quality of double-glazed windows
- Cleanliness of the glass unit inside and out . The modern design is produced on high-tech equipment without human intervention and is assembled on an automated production line, so the glass must be perfectly clean. Industry standards allow for one defect. If there are more deficiencies, contact the supplier with a complaint.
- Sealing thickness of glass sheets: for the depth of the first layer - from 4 mm, for the second - from 9 mm.
- The layers of glass sealing in the corners of the package are smooth and solid, the outer layer does not leave marks on your hands.
- Label on the window. It can be easily removed on a high-quality product immediately after its installation and contains the date of manufacture of the structure, the dimensions of the package and the name of the manufacturer. The label is removed immediately after the installation of PVC windows is completed, otherwise under the influence of sunlight it will become firmly attached to the product.
- The quality of installation is no less important than the package itself. Poor-quality installation work jeopardizes the reliability of even the most advanced structures.
Optimal number of cameras in a profile
— the five-chamber profile has a thickness from 70 to 76 mm;
— the four-chamber profile has a thickness from 64 to 67 mm;
The air chambers in the profile of a plastic window are the gap between the stiffening ribs in the window frame itself. These spaces are isolated from each other, thereby maintaining a separate temperature for each chamber. By saving on purchasing a low-quality profile, even when ordering an expensive multi-chamber package with all kinds of coatings and films, you can reduce your efforts to almost zero.
We bring the burning lighter to the glass. Pay attention to the number of reflections of flames in it. If their number is, say, three, then this means that a triple-glazed unit with three glasses is installed in the opening.
What can you do to find out on your own how many glasses are in a plastic window? If the specialists who were involved in the installation of the structure finished their work and left, then about this issue you can ask the manager of the company where the purchase and sale agreement for PVC windows was drawn up, or you can calculate it yourself.
Buying a candle for this procedure will be quite expensive, but using matches or a lighter is quite justified. Let's focus on the second option.
What should you pay attention to?
- Minimum glass thickness 4 mm. But often unscrupulous people install three-millimeter glass.
- Number of cameras . For effective thermal insulation, you should choose multi-chamber structures - with at least two chambers (or three glasses) that can eliminate street noise and winter cold.
- Triplex , which does not shatter when broken, is a two-layer glass with lamination between the layers, ensuring the safety of the package.
How to independently determine how many glasses are in a double-glazed window.
It is quite easy to independently check the number of glasses in a double-glazed unit. To do this you will need to choose from:
The day has come when all the dirty work in the apartment has been completed and a brand new plastic window adorns the window opening. However, some buyers of modern window designs only after finishing the installation exceed the number of installed glasses in the double-glazed window.
To check the number of glasses installed in a two-chamber or five-chamber double-glazed window, we proceed in a similar way - we count the number of flame reflections in the window.
Plastic windows, among other things, are classified by the number of chambers in the metal-plastic profile. It is generally accepted that the more of them, the better the window protects from temperature changes and loud sounds, but is this true? In this article we will try to figure out what camera profiles are for, how to purchase a truly reliable window, and what number of cameras is right for you.
Dependence of price on type
Energy saving glass
This type has high-quality indicators that allow you to effectively maintain the temperature in the room without releasing heat outside.
Manufacturers achieve such indicators thanks to high-tech processes used in manufacturing, the basis of which is the application of a thin, almost invisible coating to one side of the glass, which increases its reflective characteristics several times.
In addition, such a coating does not prevent the penetration of light into the room at all.
The external data of such a window will not be any different from the usual one. When installing window structures with energy-saving glass in single-chamber packages, the price, of course, will be an order of magnitude higher than with conventional analogues.
It should also be taken into account that thanks to this solution you will not only create comfortable and cozy conditions for yourself and those close to you, but will also be able to reliably protect wallpaper and furniture from fading.
In addition, by spending a certain amount on this installation option, you can give your apartment significant savings on energy resources. Buying a double-glazed window in Moscow using this technology means making a profitable investment in your future.

Safe designs
When destroyed, these types of products completely eliminate the possibility of causing injury to a person. There are currently two options for creating safety glass.
The first possible method for producing such a building material is the hardening process. It is worth noting that the price of such a single-chamber double-glazed window can significantly exceed the cost of the entire window.
At the same time, it has excellent strength characteristics and, in case of destruction, forms small pieces that do not have sharp corners.
The second option for safe production is a high-tech process, gluing together the required number of sheets of glass with a polymer film.
This type of material is called triplex. It has a very strong structure and completely eliminates the possibility of fragments appearing when destroyed.
The use of high-strength products is advisable for installing window structures in places with a significant risk of unauthorized entry or an increased level of mechanical operation.
Tinted glass
This type of glass is designed to protect the room from the penetration of sunlight.
It is produced using innovative technologies, thanks to which it acquires high-quality indicators, among which reflective abilities can be noted. Thus, ultraviolet rays penetrate into the apartment in much smaller quantities.
Tinting limits solar heat gain into the room to 70% and does not heat up at the same time. It is advisable to use this glazing option in rooms with windows facing the south side of the house.
By equipping double-glazed windows with such products, the price will not be too high, since only one side of the window will be tinted. This solution is not only a profitable, stylish solution for apartment design.
Such windows will make the facade unique and expressive, highlighting your apartment in the crowd.

Checking the fittings
Window fittings ensure a tight fit of the sashes to the frame, locking them, opening them and fixing the sashes in various positions. The operation of the entire window unit depends on its quality.
If you are offered a choice of accessories that are more expensive or cheaper, then do not save.
Cheap fittings are usually made of soft metal, and some of their elements may even be plastic.
Such products require constant adjustment, and after a couple of years, all the fittings will have to be changed.
The manufacturer of the fittings is also added here. If it was produced by an unknown company, then you can’t hope for high quality.
For increased convenience, you can order the installation of additional elements:
- Slot ventilator.
- Window sash tilt limiter.
- Sash opening limiter.
- Microlift.
- Locks on the handle.
Check how the fittings function and evaluate the ease of effort. Make sure the sashes turn where you point them.
Quality of installation of plastic windows
The customer needs not only to have an idea of checking the characteristics of window systems, but also to know how to check the quality of installation of plastic windows. Errors made during installation will significantly impair the operation of the structure. Therefore, they must be identified immediately and promptly eliminated, or the windows must be reinstalled.
You can check the tightness of the sashes using a simple test with a sheet of paper. The sheet must be placed between the frame and the sash, and then close the window. Then you need to pull the paper, it should pull out with effort. This check needs to be carried out in several areas of the window frame. The window handle should move without significant effort, but also quite freely. Make sure that you do not need to press on the frame to open the sash.
Be sure to make sure that the window is level. If you don't have a special tool at hand, you can do a simple test. Open the sash slightly and make sure that it does not move on its own in either direction.
Before ordering and installing a window structure, it is recommended to watch a video on how to check the quality of installation of plastic windows.
Fastening strength
A frequent violation of technology during unqualified installation of PVC windows is improper fastening. This could lead to serious problems with the unit in the future. Therefore, it is necessary to check the quality of the fasteners after installation.
The interval between fastening points should be no more than 70 cm. Check that the fasteners are installed on all sides of the window frame. The number of attachment points on a standard plastic window should be 10–12 pieces. Special window dowels, self-tapping screws, and anchor plates should be used as fastening elements.
Checking the assembly seam
Carefully inspect the area between the border of the window frame and the wall. The seam must be completely filled with polyurethane foam. The presence of voids and foreign inclusions is not allowed. The voids in the installation seam allow cold and dampness to pass through the window from its side. The pads and wedges that were used to install and position the window frame must be carefully insulated with foam to prevent the formation of cold bridges.
Checking the window profile
A high-quality profile will provide reliable thermal insulation of the room at any time of the year. Each profile has several internal chambers, hollow or filled with insulation.
According to building codes, a profile with at least 3 chambers can be used for residential premises. Two-chamber profiles are used only in non-residential premises.
It is believed that German profiles are of the highest quality.
Indeed, Germany has created one of the best technological cycles for manufacturing window profiles in the world.
At the output, a multi-level check is performed, eliminating the possibility of defects.
The most popular brands are Rehau, KBE, Veka, Gealan. These companies provide a guarantee on their profiles for about 40 years.
What to pay attention to:
- Profile thickness. The thicker the profile, the warmer the window. In the middle zone, the acceptable thickness is considered to be 57-70 mm.
- Inside the profile there is a reinforcing metal contour, which has a square cross-section.
If the profile is even thicker, then a thicker glass unit can be inserted into it.
The best quality has a galvanized steel contour, and the metal thickness should not be less than 1.5 mm.
Some unscrupulous manufacturers may not reinforce their profiles with metal at all, since it is very difficult to check its presence visually.
However, this can be done using a magnet, attaching it to the profile in those places where there is no sash. If there is a metal contour inside the profile, then you will feel it.
