The difference between two-chamber plastic windows and single-chamber windows. Which double-glazed windows are better - single-chamber or double-chamber

Given the ever-increasing tariffs for housing and communal services, warming your own home is very important point which should be approached with the utmost care. Properly carried out work will significantly reduce the cost of your family budget in winter period. Many of you probably know that the most serious sources of heat loss are windows and doors, and therefore they should always be given special attention.

Single or double glazing

PVC windows are the most the best option for those who want to improve the energy efficiency of their home, but there are many questions to be solved when choosing. Such, for example, how to choose - single-chamber or double-glazed windows. Let's highlight the main parameters by which comparison should be made:

• heat transfer and light throughput;
• sound insulation level;
• thickness and weight;
• design;
• price.

Today there are certain misconceptions about this, and they are quite common. In particular, it is considered that more cameras at a double-glazed window, the more effectively the window will retain heat. This is not an entirely correct statement, since a number of other characteristics should be taken into account here. Be sure to calculate the feasibility of installing one or another type of double-glazed windows.

They have both their pros and cons, and the difference in price is also present. But after all, no one wants to overpay for "something unnecessary", since the windows are changed just because of the desire to save money, and therefore it is necessary to do right choice, allowing you to increase energy efficiency and comfort without additional overpayment.

Price should not be the determining factor

At the same time, the cost should not be put at the forefront, because with the wrong choice, heat loss will be more significant, and the noise level in the room will gradually become annoying. Therefore, if the house is located, for example, in the central part of the city, then it is better, of course, to install double-glazed windows. Do not forget about the peculiarities of the climate - for regions with short and relatively warm winters, when the air temperature rarely drops below minus 10, single-chamber ones are quite suitable.

Installation of a two-chamber double-glazed window is more laborious, and its weight will be somewhat larger. The last circumstance is mentioned for a reason. More weight means more stress on the hardware. For glazing a balcony, single-chamber double-glazed windows are best suited, since they are lighter. Accordingly, the parapet will not be subjected to additional load. Moreover, if your balcony is already glazed, then for the window in this the room is suitable single chamber option. In most cases, this will be justified and at the same time provide sufficiently high energy efficiency and reliable protection from external noise.

If we are talking about a window overlooking a busy street or a nearby night club, then in most cases it is recommended to install double-glazed windows. They are characterized by a higher level of sound insulation, which means that additional financial costs will be justified here. Do not forget that you can combine different variants. For example, if the windows of one room overlook a quiet courtyard, then a single-chamber package will suffice here, while in another you can already put two-chamber ones.

It should also be noted one rather important point. If there are special energy-saving glasses in a single-chamber design, then it will be quite competitive compared to a two-chamber one. Meanwhile, in terms of weight, as well as in terms of cost, you get an advantage. However, this only applies to energy efficiency.

A double-glazed window will better protect against external noise. This has already been confirmed by the results of studies using special equipment. They, in particular, showed that a double-glazed window can reduce the noise level in the room by about 40 decibels. Due to this circumstance, such structures are installed not only in apartments, but also in office space located in noisy central areas of the city, with busy traffic.

It is also worth comparing such characteristics as the throughput of outdoor light and glass. Here the advantage will be on the side again single-chamber double-glazed window. The two-chamber design, due to the presence of additional glass and an air partition, transmits external heat and light flux into the room worse, which means that the room on a sunny winter day will not heat up as intensively as with a single-chamber version. However, in summer, in hot weather, this disadvantage turns into a virtue.

Now let's move on to such an indicator as cost, since, as you know, you have to pay for everything. Prices for double-glazed windows are higher than for single-chamber ones - with standard properties, the difference is about 25 percent. It is easy to guess that when glazing the entire apartment this difference will be impressive enough. With financial constraints, the mentioned will be optimal combined option when the choice of single-chamber or double-glazed windows depends on the specific circumstances.

Let's summarize the above. As you already understood, it is worth deciding on the type of double-glazed window, taking into account a number of circumstances. Important role here have the climatic features of your region, as well as the location of the apartment. Be sure to take into account the noise level outside the window, since single-chamber structures do not protect it effectively enough compared to two-chamber ones. In the southern part of the country, the second option is in most cases inappropriate to use - unless you want to get rid of annoying street noise.

The financial component plays an important role in the choice, however, one should not be guided by only one cost, making a choice in favor of one or another type of construction, since the wrong choice will nullify the initial savings.

On the this moment time, probably everyone heard about plastic windows, moreover, most of those who know have already installed them. The products in question are in demand for a number of reasons, the main of which are their reliability, strength, durability, high price and, of course, practicality.

In addition to coloring, such windows may also differ in the number of double-glazed windows located in them. The most common are one and two-chamber designs, although three-chamber ones also have their own consumers and some demand.

So, let's take a closer look at the topic - single-chamber and double-glazed windows, what is the difference, and what characteristics each type has.

Single-chamber double-glazed window

Let's start our consideration with something simpler. Your attention is given to single-chamber designs with all their features and characteristics. The number of cameras - this indicator is often the decisive criterion when choosing one or another plastic construction.

It should be immediately noted that the parameter in question affects not only the cost of the plastic structure, but also not its mass, the characteristics of the energy-saving and heat-saving indicator.

Here, we can immediately conclude that the difference between single-chamber and double-glazed windows is in weight, while it is inexpensive, which is why it is so often chosen by a consumer with an average level of income.

Such windows are suitable for installation, both in summer cottages and in residential premises - houses, apartments and offices. In the context, the double-glazed window in question looks like a pair of glasses, between which there is a remote-type frame.

When assembled, it is not so easy to distinguish the difference where a single-chamber double-glazed window is, and in what design there are two of them, and unscrupulous dealers often use this plastic windows, which wishful thinking and “sell” the consumer a single-chamber double-glazed window at the price of a two-chamber one. That is why, it is necessary to be careful when choosing such a product (sometimes even a distance frame can be displayed, that is, double, and give a false idea of ​​the number of cameras in the design).

Most often, in the considered double-glazed windows, 4 mm glasses are used, and they must be of the same thickness (the chamber, with such a thickness, must be at least 16 m).

Double glazing

The two-chamber design is a similar design to the one previously discussed, but with three panes. This acquisition will become profitable and correct if the consumer appreciates the warmth and comfort in his home. As mentioned earlier, the amount of retained heat in the house depends on the number of glasses.

In the double-glazed window under consideration, the glasses can be located at different distances, but most often from 7 to 15 mm. In this case, we can also mention the high efficiency of their installation, namely, with such double-glazed windows in the room it is warm and cozy, among other things, they also have such a feature as a high level of sound insulation.

For regions where winters are quite cold - this glazing option window openings, is considered optimal and correct than single-chamber. Even if you live near the stadium, you will not have to wake up in the evening because of the noise that is happening on it, because you will only hear what is happening inside the house or apartment.

A double-glazed window usually has a width of 25 to 45 mm; also, do not forget that this indicator, first of all, depends on the similar size of the frames that are located between them, as well as the thickness of the glass itself.

If the need for sound insulation is increased, then it is possible to purchase a double-glazed window with glasses, the distance between which is different, in the case of standard conditions operation, a double-glazed window is great, in which the glasses are at the same distance from each other.

What is the difference between single and double glazing?

Despite the fact that the question may seem quite elementary, it worries many consumers who are going to become owners of plastic windows or doors. Let's immediately dot the e, so to speak, the first and most important difference between them lies in the number of glasses inside the structure.

If you deal with this issue in more detail, you can make a thorough description of each of them:

• The composition of a single-chamber double-glazed window is 2 glasses (such a double-glazed window among the pros is called standard), lightweight, while not giving a special load on the fittings. It should be noted that the permeability of sunlight in this case is quite high. Thermal insulation is lower than in a two-chamber one, and the situation is also with sound insulation.
• A double-glazed window already consists of three glasses, respectively, its mass is greater than in the previous case, and the load on the fittings too. They transmit light worse, but at the same time tightness is an order of magnitude higher.

Each of the presented options has a difference, its pros and cons, so it’s definitely impossible to say which double-glazed window will be the best option. In addition, this is influenced by a lot of circumstances and criteria that must be taken into account when choosing.

The use of single and double glazing

So, now you need to understand in which case, and under what circumstances, to choose a single-chamber double-glazed window, and where a two-chamber one would be appropriate. As mentioned earlier, standard double-glazed windows will be appropriate in the case of a summer residence, that is, if you need to install plastic windows in country house or dacha, then this is the most suitable option, what is it in quality characteristics as well as pricing policy.

Also, single-chamber double-glazed windows will good choice for apartments and houses in the greasy parts of the settlement, as well as for regions without strong winds and frost.

As for double-glazed windows, here it is necessary to immediately note the difference as a high cost compared to the previous version, so this criterion can already affect the number of people who want to buy it. In principle, the installation of such a design would be an excellent option for areas with strong winds and frost, as well as for rooms that are located close to noisy public places(tracks, stadiums, parks, etc.).

Pros and cons of both types of double-glazed windows

Since we have already found out the difference between single-chamber and double-glazed windows, you need to understand what type of construction you need, you need to point by point and clearly define their advantages and disadvantages.

A single-chamber double-glazed window has a number of advantages: light, practical, durable, inexpensive, and transmits light well. Among the shortcomings, the following points can be distinguished:

• It is not recommended to install in rooms located near noisy places.
• will not justify itself in regions with harsh climatic conditions

The difference between a double-glazed window and a single-chamber, the first option has a high sound insulation, which means that they can be installed everywhere, regardless of the noise level. Such double-glazed windows retain heat very well, so this is an ideal option for creating comfort.

The disadvantages of this design include their large weight (compared to a single-chamber), as well as a low level of transmission of sunlight.

In any case, a plastic window is profitable, practical and durable, and each should be determined individually with the number of cameras.

Many do not even know what a double-glazed window is as a separate concept. They consider it synonymous with the word "window". Therefore, when deciding on an order at the seller, the filling of a double-glazed window is far from the first thing they pay attention to. But this is wrong. A double-glazed window occupies approximately 80% of the window area. And most It is its configuration that provides warmth and comfort in your home.

double glazing- this is a structure consisting of several sheets of glass, which are interconnected along the contour using a distance frame and various sealants. Glasses form closed chambers with air or other gas inside.

Remember: a lot depends on which double-glazed window is inserted into your window! Let's get to know the details.

Single-chamber double-glazed windows

And further. Compared to single, double-glazed windows are one and a half times more massive. So, before repair, this indicator should be taken into account. What if the opening in your apartment is not designed for this? Or is the balcony where you are planning double-glazed windows too dilapidated?

Three-chamber double-glazed windows

If you are looking for a window handle, it will help you decide.

The cost of different double-glazed windows

If you are torn between ordering single-chamber and double-glazed windows, then the price will not be a decisive argument for you. Double glazing is almost a quarter more expensive than single glazing. It would seem like too much. But it’s not so scary, given that the price of a single-chamber double-glazed window from the manufacturer starts at 750 rubles per square meter.

But the price of three-chamber double-glazed windows differs from the previous ones, naturally, upwards. On average, it is 50% higher than the price of double glazing. Moreover, the glass itself will not be so expensive as the profile. To hold so much glass, it must be quite solid in size.

New! Energy-saving double-glazed window

In addition to one-, two- and three-chamber double-glazed windows, there are other types of window structures, the purpose of which can be completely different. These are four- and five-chamber ones, which were probably created for Antarctica or for crazy millionaires. There are also energy-saving, noise-insulating, armored, self-cleaning double-glazed windows.

Energy-saving double-glazed windows do not release heat from the inside and do not let it in

Let's dwell on energy-saving double-glazed windows, since Russians choose them more often than the others mentioned above. First of all, you need to understand that energy-saving glass does not differ fundamentally from ordinary double-glazed windows. It's just that instead of the usual ones, energy-saving glasses are installed in it - just one of them, and not the most expensive.

And one more thing: inside the chamber at the energy-saving double-glazed window, no compressed air, as usual, and gas - argon. Argon does not let the cold in, and the silver coating provides a "mirror effect". This means that on a hot summer day, the house will remain cool, and on a cold winter, the heat from the batteries will be reflected into the room.

This option is ideal for you if you are looking for a window that is warm and light at the same time. It retains heat better than a two-chamber one, and weighs 30% less.

An energy-saving window is not ideal. It lives only 10-15 years. During this time, the argon will completely evaporate, and the silver ions will dissipate. On the other hand, it is not so scary, because the energy-saving double-glazed window simply turns into a regular one.

In conclusion, I would like to state the following. Disputes about which double-glazed windows are better, and in what conditions they should be used, have been going on for more than one year. As they say, there are no comrades for the taste and color. The classics of humor were right: to whom the mare is the bride!

There are many individual things here. When choosing a double-glazed window, think carefully about what you want from this acquisition. Agree, the number of cameras in window construction does not have of great importance, if there is little money and when it shamelessly blows into all the cracks. And if batteries are on fire in your apartment, it will be hot even with a single-chamber double-glazed window.

In the cold season, we often face the problem of heat loss in houses and apartments. Without additional thermal insulation heating system simply cannot cope with the drafts formed at the entrance and balcony doors, windows and ventilation system. For example, up to 50% of heat from an apartment can only come out due to cracks in window frames!

One of optimal solutions This problem is the installation of high-quality plastic windows with double-glazed windows. And here many people have a question about which double-glazed window to choose: single-chamber or two-chamber? First, let's look at the characteristics of each of them, and then compare which type of double-glazed window is best for different conditions.

Characteristics of single-chamber double-glazed windows

Many people, seeing the name "single-chamber", assume that such a double-glazed window does not differ at all from the usual window frame with one glass. This is an erroneous statement. In all types of double-glazed windows, the chamber consists of two panes separated by an aluminum frame and creating a hollow space between them. This space is usually filled with dehumidified air and an absorbent that absorbs residual moisture. But the number of cameras can reach three, respectively, there will be four glasses in such a window.

So what is the difference between a single-chamber double-glazed window? Its advantages:

• Due to its low weight, a window with a single-chamber double-glazed window does not create an unnecessary load on the fasteners and the opening structure. Such windows do not fail longer;
• Lets in up to 80% more light. At first glance, this difference is almost never noticeable, but visually a well-lit room seems larger;
• Single-chamber double-glazed windows, the glasses of which are silver-coated on one side, and the chamber is filled with argon instead of air, are energy-saving. Such windows retain heat no worse than two-chamber ones;
• Less price. Such a double-glazed window costs an average of 15-20% less than a two-chamber one. This indicator is not so great, but often plays decisive role when choosing a double-glazed window.

Single-chamber double-glazed windows also have disadvantages:

• Low noise isolation. These double-glazed windows are able to reduce the noise level by only 32 dB;
• They also have a low coefficient of resistance to heat transfer. This means that condensation on the glass of a single-chamber double-glazed window will form at a temperature of about -8 degrees Celsius;
• The heat transfer resistance index of double-glazed windows with one chamber is lower by a third in comparison with two-chamber ones;

The thickness of the single-chamber package depends on the size of the distance frame and varies from 1.8 to 3.6 centimeters. At the same time, the standard thickness used in most construction companies, is 2.4 centimeters.

The standard thickness of glass in an insulating glass unit is 5 millimeters, but when using glass with a thickness of 6 millimeters, the same thermal conductivity characteristics can be achieved as with double-glazed windows.

Characteristics of double-glazed windows

Double-glazed windows, as the name implies, consist of two air chambers and three glasses, respectively.

Among the advantages of such windows are:

• High degree of noise isolation (up to 35 dB). Moreover, there is a special design of such double-glazed windows, which allows you to drown out street noise over 35 dB. This property is provided different width remote frames in both chambers;
• The heat transfer resistance coefficient of such double-glazed windows is much higher. Condensation on the glass is formed only at a temperature of -30 degrees Celsius, provided that the humidity in the room is up to 50%;
• Improved thermal insulation. The principle “the more the better” applies here. Two air gaps will ensure you not only the absence of extraneous noise in the apartment, but also the preservation of heat in winter.

Cons of double glazing:

• The price is slightly higher than that of single-chamber;
• Low light transmission. The difference in lighting outdoors and indoors can be up to 6%;
• Greater width and, accordingly, greater weight. As a result, an even greater load is placed on the supporting structures, and the wear of such windows increases.

The thickness of double glazing is calculated using the formula 4 + 10 + 4 + 10 +4. From it it is clear that the standard glass thickness is 4 millimeters, and the thickness air gap- 1 centimeter.

The disadvantages of these double-glazed windows, associated with thickness and weight, are easily eliminated through the use of quality fittings and reinforced window profiles high strength.

Double-glazed windows can also differ from each other. As already mentioned above, different thickness glasses and different distance between them provides high-quality sound insulation in room. In addition, a method of combining different types of glass in such double-glazed windows is used to give them the properties of sun protection, impact resistance and energy saving.

Where is it better to install single-chamber double-glazed windows

Often problems with heat loss and high level noise in the room related to wrong choice double-glazed windows. The desire to save a couple of thousand rubles on a cheaper option can play a cruel joke: you will have to overpay for reinstalling almost new windows.

Moreover, in many major cities state commissions prohibit the installation of single-chamber double-glazed windows, as according to SNiP thermal characteristics these windows are not suitable for middle lane and, especially, for the northern regions. In what cases will the installation of a single-chamber double-glazed window be justified?

• Glazing of balconies and loggias

If you do not plan to insulate this room and make it a residential part of the apartment, it is not advisable to overpay for heat-resistant double-glazed windows. Besides, lightweight construction such windows will not in any way damage the hinged balcony;

• Balcony block installation

If your balcony is glazed, even if it is ordinary wooden frames, you no longer need to install an interbalcony door and double-glazed window. The balcony space will serve as a second chamber so that the room temperature will remain the same;

• Summer house glazing

Despite the fact that summer houses are built of wood, it is more profitable to install not wooden, but plastic windows in its openings. At the price they are the same, but installing ready-made double-glazed windows is much more profitable and more convenient. Single glazing is enough to maintain comfortable temperature in this recreation area;

• Glazing of the terrace in the house

The reasons why it is better to install single-chamber plastic windows on the terrace are the same as in the case of the glazing of a summer house.

• Installation of windows in the southern regions

Overpay for unnecessary benefits and additional characteristics does not make sense if the average temperature in your area during the cold season does not fall below -10 degrees Celsius.

When should double glazing be installed?

In the glazing of apartments and houses in the central part of Russia, double-glazed windows are mainly used. Their characteristics are best suited for low average temperatures.

If you live in a noisy city, next to a highway, airport or railway tracks, the problem of annoying noise flow from the street will be successfully solved by installing high-quality double-glazed windows.

But if we are talking about the northern regions of our country, where frosts often fall below -30 degrees, you will need triple glazing. Their huge minus in cost, but high price justified by the improvement of each characteristic of double-glazed windows.

In addition, it must be remembered that even the most high performance double-glazed windows by themselves do not guarantee high-quality filling of the window opening. Equally important is the quality and professional performance of window installation.

In addition to the characteristics and recommendations described above, the following tips will help you choose high-quality double-glazed windows for an apartment and a house:

• The presence of a desiccant or molecular sieve in the design of the double-glazed window ensures the rapid absorption of moisture formed on the glass. For different types of gases are used different types dehumidifiers;
• Also, the problem of water vapor condensation on glass can be solved by “warm” inter-chamber frames. They are able to maintain the required temperature at the edges of the glass, minimizing the risk of thermal bridges;
• If you want to increase the distance between the glasses, then you should stop at a width of up to 2.4 centimeters. Practice shows that a large width in this case will lead to a deterioration thermal insulation properties double-glazed window;
• The space filled with argon will not give the expected effect if the outer glass of the double-glazed window is not energy-saving;
• You can check whether argon is really pumped into the chamber by simple attentiveness. In such a double-glazed window there must be a valve through which this gas was pumped;
• To distinguish energy-saving glass from ordinary glass, you can conduct a simple experiment with a lighter or a match. The light must be brought to the glass and the image seen should be checked: the flames should be reflected in the same way as in the mirror, but one of them should be of a pronounced red or pinkish hue. This signals that this glass is energy-saving;
• A single double-glazed window with glasses of different thicknesses will also have some soundproofing properties. It is even better if one of the glasses is energy-saving.

A short video about the differences between single-chamber and double-glazed windows:

When choosing plastic windows for a house, the question often arises, which double-glazed windows to buy?

All glass for plastic windows can be ordinary standard, tempered and triplexed.

The choice ranges between single-chamber and two-chamber, which differ in the type of construction, the number of glasses used. How big is the difference between these two options? It is this question that we will try to answer, along the way, finding out what they are similar designs how they can differ from each other.

Varieties of double-glazed windows for windows

The design of the double-glazed window includes: air chambers, glasses, aluminum profiles, absorbent, butyl, polysulfide.

First, let's define what a double-glazed window is. This is a special design, which consists of several glasses interconnected in compliance with tightness. For connection, apply aluminum profile in the form of a frame, sealants, between the glasses the space is completely filled with an ordinary air mixture or an inert gas (it is best if it is argon, but krypton can also be used).

Plastic windows produced today are divided into single-chamber, that is, consisting of two glasses and a layer between them, and two-chamber, that is, from three glasses and two air chambers. But plastic windows can have not only ordinary glasses, but also specially processed:

• energy saving;
• multifunctional;
• sun protection.

All glasses for plastic windows, in turn, can be ordinary standard, tempered, multi-layered, that is, triplexed. Most often, energy-saving products of a standard type are used for double-glazed windows, but hardened and multilayer ones are used in cases where additional protection is required.

Energy-saving double-glazed windows can be manufactured using various technologies:

Thanks to the heat-reflecting coating, the room is warm in winter and cool in summer.

• Pyrolytic-produced K-glass is more expensive but less efficient today, when other production methods are already being used;
• I-glass, or low-emission glass, is produced using magnetron technology.

The first energy-saving bags are made by applying a single layer of metal oxide directly to hot glass. But today more effective method application of silver and other metals by the method of the thinnest spraying is recognized. This allows you to not transfer heat to the outside.

Single chamber packages

Single-chamber plastic windows are a structure that consists of two panes separated from each other by a spacer made of aluminum. In this case, the resulting gas layer, which separates the two glasses, does not come into contact with external environment, being an excellent heat and sound insulator that protects the interior.

Single-chamber plastic windows differ from traditional ones in that they are absolutely hermetic, that is inner part double-glazed window is reliably protected from condensate, the occurrence of a freezing point.

Temperature on the surface of the inner glass of the window: clear glass, double glazing, double glazing.

For such windows, structures with a thickness of 20 to 24 mm are used (in the first case, aluminum is used, in the second, plastic). The noise reduction from the street is up to 34 decibels.

Of the minuses that distinguish such plastic windows, it should be noted that they are not as reliable noise protection as those of two-chamber ones, and the coefficient for heat transfer resistance is not so high. But there are also advantages - low weight, which is perfectly combined with strength and reliability, high light transmission, durability.

The cost of such windows is also not very high, which is often decisive factor in their favor. The use of energy-saving glasses for such structures makes their installation more expedient than the installation of expensive two-chamber ones.

Double chamber packages

Double-glazed windows, despite numerous mythical advantages, differ from single-chamber windows only in the number of glasses, chambers, spacers. But it is precisely such a package of two cameras that allows you to create a real barrier from almost any negative impact atmospheric factors.

In many cases, the use of such packages is fully justified, they can be installed in a variety of climatic zones, and in combination with M14 mm glass, they are able to fully provide comfort and coziness. The use of such double-glazed windows allows to reduce the noise level by about 40 decibels, that is, they are in demand not only for city apartments, but also for offices and commercial buildings located in the city center. To choose the right two-chamber package, you must be guided by a formula of this type: 4-10-4-10-4.

Here the thickness of the glass for the double-glazed window, the width of the air gap are indicated sequentially. Particularly effective are plastic windows, for which special energy-saving glass is used. But they are rarely used for apartments, they are mainly suitable for administrative buildings or in cases where balcony windows living quarters face noisy streets, avenues. Therefore, when deciding which plastic windows are better, one- or two-chamber, determine in which rooms they will be installed, whether such noise protection is necessary.

Which double glazing is better?

So which is better: single or double glazing? It is impossible to answer this question unambiguously, since both types have pros and cons of application. For example, a single-chamber package with energy-saving glass is able to retain 25 percent more heat than a conventional two-chamber package.

At the same time, the latter option is distinguished by a large weight, that is, its installation is more costly and complicated. And more weight is a greater load on the fittings, which will fail faster. That is, the question of whether to buy single-chamber and double-glazed windows should be decided not by the thickness and amount of glass, but by completely different indicators.

When choosing, you need to pay attention to such factors as the transmission of visible light and ultraviolet radiation, energy saving. Consider this example:

1. Visible light transmission for a single-chamber energy-saving double-glazed window is 80%, for a conventional single-chamber - 81%, and for a two-chamber ordinary - 74%.
2. The transmission of ultraviolet for energy-saving single-chamber double-glazed windows is 35%, for ordinary single-chamber - 54%, and for ordinary double-glazed windows - 45%.

It is possible to distinguish energy-saving glass from simple glass at home using a lit match or lighter.

AT this example we see that a single-chamber package with special energy-saving properties is much more efficient than an expensive two-chamber package, but with ordinary glasses. It also has its own peculiarities: it is not recommended to install more than one energy-saving glass, since the solar factor will be much reduced. That is, there will be a need to use additional protective glasses, and this will increase the cost of glazing.

As you can see, energy-saving glass should also be used very carefully. Attention should also be paid to the distance between the individual glasses, whether argon is used for filling, which further increases thermal insulation.

When choosing double-glazed windows, many people think that the more glass, the more reliable the window will be to protect from the cold, but this is far from the case. Often, thinner bags with fewer elements provide effective protection.

Therefore, do not rush to make a choice, decide which characteristics of a double-glazed window are important to you. Many experts recommend giving preference to single-chamber with energy-saving glass, which will provide greater protection and thermal insulation, sound insulation of the house.
