What is better double glazing or single glazing. The choice of double-glazed window between single-chamber and double-chamber

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

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 glass, 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.

• K-glass, produced by pyrolytic technology, 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 air gap. 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.

IN 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 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 glass with energy-saving glass, which will provide greater protection and thermal insulation, sound insulation of the house.

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 against 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 again be on the side of a 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 incorrect choice nullify the initial savings.

N.A. Murashko, representative of the Guardian company in Ukraine and Moldova

While the general level of awareness among window buyers is growing, today we still hear questions from them: “ Which windows are better - Rehau or KBE?", "Which is better - two-chamber double glazing or single chamber energy saving glass?”, “Argon “leaves” the double-glazed window?”, “Argon explodes?”. We will try to give answers to these and other questions most frequently asked by customers.

To begin with, everyone who wants to install or replace windows must understand for himself: what does he want from the window?

just close the opening cheaper or put a window that looks like a neighbor's window. Note that the focus on the most low price, not paying attention to anything else, will provide you with a very high probability of permanent problems with this window;

make the window right once and for a long time. With this approach, we recommend that the buyer think about what is important in his particular case:

• Thermal insulation (required almost everywhere and always)
• Noise isolation (in many cases relevant)
• Protection from solar overheating and psychological comfort of being indoors (very important when large areas glazing oriented to the south, west; glass roofs and facades)
• Security (apartments and offices on the 1st floor, private houses).

In this article we will talk about thermal insulation: by what means is it achieved, which makes the window really warm, avoiding complex graphics, isotherms and tables, and we will operate in terms that are understandable to a wide audience.

Often, when choosing a window, the attention of the buyer is diverted to the choice of profile brand and is not always given due attention. double-glazed window. At the same time, measuring the thermal insulation of a manufactured window only by the brand of the profile is the same as evaluating the quality of a car by the grade of steel from which the body is made. Meanwhile, glass occupies about 80% of total area window. Therefore, if the seller talks a lot about the number of cameras in the profile and does not pay attention to the parameters of the double-glazed window, such a “specialist” is not entirely competent.

So, first of all, it is from the parameters double glazing the thermal insulation of the window will depend. It is about the double-glazed window that we will talk about.

A double-glazed window is several glasses hermetically connected to each other using a special frame and sealants. In this case, such a package is filled with air or gas (argon, krypton), which improves thermal insulation properties double-glazed window. Double-glazed windows are single-chamber (two glasses and one air chamber between them) and two-chamber (three glasses and, accordingly, two air chambers).

Modern technologies in the production of glass have stepped forward and now there are many types of special glass on the market. By function special glasses are divided into:

• energy saving;

  sun protection;

  multifunctional.

In this case, any of the special glasses can be:

standard;

hardened;

triplexed (multilayer).

In metal-plastic and wooden windows, for energy saving, standard windows are most often used. energy saving glass. Tempered or laminated energy-saving glass is used in applications where security or intrusion protection is required.

According to the efficiency and production technology, energy-saving glass is divided into:

K-Glass - is made according to the old (from the 70s) pyrolytic technology. Glass is less efficient and more expensive. Can be processed in primitive conditions.

I-Glass (more correct names are Low-E, low-emission glass, ClimaGuard, Planitherm…) is a new (from the 90s) magnetron production technology. More efficient glass with affordable price, for the storage and processing of which special conditions and professional skills are required.

The first step in energy-saving glasses was K-Glass. It was produced by applying a single layer of metal oxide to hot glass. Later (in the 90s in Europe, and in the 2000s in Ukraine) K-Glass was almost completely replaced by the more efficient Low-E - multilayer magnetron sputtering of the thinnest, invisible to the human eye, metals and oxides.

Thanks to these metals (including silver), heat is not transferred to the outside, but is reflected back into the room, thereby reducing heat loss from the room several times.

To date, more than 90% of the consumption of energy-saving glass in Ukraine is glass produced using advanced magnetron technology.

A single-chamber double-glazed window with energy-saving glass 4-16-4i saves 25% more heat compared to a double-glazed window 4-10-4-10-4. At the same time, one should not forget that a two-chamber double-glazed window is 1.5 times heavier. And this is a big burden on window fittings, which means - a sash with a two-chamber package, all other things being equal, will sag faster and will not close tightly. But loose closed window that's a big heat sink.

Since the coating is hidden inside the sealed double-glazed window and cannot be damaged, the service life of the coating is equal to the service life of the double-glazed window itself. Numerous tests and 20 years of experience in the use of low-e glass around the world have shown the exceptional reliability of such coatings.

For the normal growth of flowers, visible light and ultraviolet light are important, which cleanses the room of germs. The warmer surface of the glass allows the plants to feel comfortable even in winter.

All the talk about the fact that energy-saving glass does not transmit ultraviolet light is fiction from a lack of information. What really does not let ultraviolet through is PVB film, on the basis of which triplex or different kind colored sun protection films that are glued to the glass.

You can, there's nothing wrong with that. But the improvement in thermal insulation will be insignificant (2-3%), but the solar factor will decrease by 9%, i.e. will be more comfortable in summer. But to protect against solar overheating, there are special sun protection glasses: SunGuard, ClimaGuard Solar, etc., about them - in a separate article on sun protection.

Double-glazed window with two energy-saving glasses and a distance of at least 10 mm. For example, 4i-10-4-10-4i. Filling the chambers with argon will additionally increase the thermal insulation of such a double-glazed window. The heat transfer resistance of the central zone of the double-glazed window 4i-10Argon-4-10Argon-4i will be 1.27 m 2 K / W, or, in other words, 40% warmer than brickwork in 2 bricks!

Of course, it depends on many factors: wall and roof materials, window sizes, efficiency of the heating system. On average, replacing all double-glazed windows with ordinary glass for double-glazed windows with energy-saving glass provides savings of up to 35% on heating. At the same time, the cost of such glass is relatively small and will pay off in the first year.

There is the concept of "Solar factor" - the total % of the transmission of solar heat (not visible light, namely solar heat) through the double-glazed window into the room. The higher it is, the faster the sun heats the room through the glass. The solar factor for a standard double-glazed window is 77%, while for an energy-saving one it is 65%. In other words, through an energy-saving double-glazed window, the room will heat up 12% more slowly.

We unfairly pay little attention to the solar factor, and many problems are associated with this in buildings with glass facades. But the issue of sun protection is complex and voluminous. Its explanation should be devoted to a separate article.

Firstly, argon (an inert gas) has a higher viscosity than air, which means that its particles move more slowly between the glasses and more slowly transfer heat from the inner glass to the outer one.

Secondly, argon has less heat capacity and thermal conductivity, and therefore it removes less heat from the inner glass. Roughly, this can be compared with the following example: if you pick up a piece of aluminum and plastic profiles, then aluminum will seem colder to you. In fact, their temperature is the same, but aluminum has a much higher heat capacity and thermal conductivity, and therefore aluminum absorbs the heat of your hands faster.

Argon is more efficient in double glazing with energy saving glass. The thermal insulation of a 4-16-4i double-glazed window is increased by 11% when filled with argon compared to filling with air. A single-chamber double-glazed window without energy-saving glass, when filled with argon, will become warmer by only 5-6%.

Argon is an inert gas, i.e. he doesn't get involved with anything. chemical reactions Therefore, it is absolutely harmless to humans. Argon does not burn, does not explode and is not radioactive.

The short answer is that it erodes, but very, very slowly, and even after 7-8 years the double-glazed window into which argon is pumped will be warmer. The main thing is that argon is really pumped in and the double-glazed window is assembled according to technology. It is especially important to apply the primary sealant (butyl) without breaks on the distance frame of the double-glazed window.

One argon molecule contains one atom, respectively - the size of the molecule is very small compared to the molecule of nitrogen or oxygen. Therefore, if the pressure inside the double-glazed unit is higher than outside (for example, the double-glazed unit heats up, and, accordingly, the pressure in the space between the panes increases), the molecules (!) of argon can “leave” through the sealant, especially if there are breaks.

In 2005, at the Glass Processing Days conference in Finland, a report was discussed on the topic “Gas filling of double-glazed windows”. According to studies by Italian scientists (Stazione Sperimentale del Vetro, Construction Glass Laboratory), the loss of argon from double-glazed windows is only 2-3% per year. At the same time, double-glazed windows assembled and installed in windows and facades up to 7 years ago were tested.

For skeptics who will say: “Well, this is Italy!”, I will answer that today modern Ukrainian double-glazed windows production (such as Altis-Glass, Paritet, Line Wood, Gualos, Busel, Fiberglass, Mikol, MasterOk, Euroglas, Glassline, Polisklo...) are not inferior to modern Italian factories. In addition, the products tested in Italy were produced up to 7 years ago, when somewhat different, “early” glass assembly technologies were used.

In Europe, much attention is paid to the problems of energy saving, since energy, primarily heat, is expensive. For example, in Germany, 95% of windows are installed using energy-saving glass (70% of windows - with single-pane double-glazed windows and one heat-saving glass, and 30% of windows - with two-chamber double-glazed windows with two heat-saving glasses).

In Spain, single-chamber double-glazed windows with energy-saving glass are used.

In Finland standard window installed with a double-glazed window with the obligatory use of one or two heat-saving glasses.

Experts expect that in the next 5-10 years, European consumers will completely switch to windows with double-glazed windows made of two heat-saving glasses.

In Europe (and not only in Germany, but also in neighboring Poland) there are "Energy Passports of Buildings" - a document confirming that the thermal insulation of all elements of the house, including windows, meets the standards. Such passports exist for both new and old buildings. If you are selling a house, even an old one, without energy passport, you need to pay a very large tax (it is cheaper to insulate the facade and change windows). In the coming years, energy certification of buildings will be introduced in Ukraine.

The new Ukrainian standards that are already in force require such a level of window thermal insulation that in order to achieve it throughout the territory (except for the Southern coast of Crimea) it is necessary to use energy-saving glass. But in fact, energy-saving glass should also be used on the South Coast, as it protects against overheating in summer.

Ukraine has a limited supply of its own energy resources. And the sooner we enter Energy Saving Technologies, the more confident our country will feel in an era of rapidly rising energy costs.

The choice of a double-glazed window should be approached wisely, because it performs important functions: it protects from the cold, drowns out noise, and gives the house sunlight. When choosing plastic windows, people often doubt what to choose: single-chamber or double-glazed windows.

In this article I will talk about the main differences between single-chamber and double-glazed windows and which one is right for you.

Single-chamber double-glazed window

It is easy to guess that a single-chamber double-glazed window consists of two glasses and one air chamber. As a rule, its glasses are 4 mm thick, and the air chamber is 16 mm wide, but the proportions may be different.

The functionality of a double-glazed window greatly depends on its configuration. You can choose double-glazed windows with ordinary glass or energy-saving glass, which will keep your home warmer in winter and cooler in the hot season.

At the same time, a single-chamber double-glazed window will not provide the same high protection against noise as a double-glazed window. In addition, it retains heat in the house 20-30% less efficiently - however, this disadvantage can be compensated by a single-chamber energy-saving double-glazed window.

Double glazing

The double-glazed window consists of three glasses and two air chambers between them. Most often, such double-glazed windows are made of glass with a thickness of 4 mm and chambers with a width of 12 mm.

Different configurations of a two-chamber double-glazed window allow it to perform certain functions. So, a two-chamber double-glazed window can be with ordinary or energy-saving glass, with different widths of chambers, with different glass thicknesses. The level of heat in the house, the silence and the amount of light depend on the selected configuration.

For example, a double-glazed window with ordinary glass will retain heat in the house in much the same way as a single-chamber double-glazed window with energy-saving glass. But if this technology is applied in a double-glazed window, the performance will be higher. Also, a two-chamber double-glazed window with chambers of different widths and glasses of greater thickness will well protect the house from city noise - I already wrote about this in the material about.

We choose single-chamber or double-glazed windows depending on the type of room

We have already analyzed the functionality and main differences between double-glazed windows, but how to understand which double-glazed window is right for you? To do this, it is important to take into account the type of room and external conditions, as well as understand what you want to get from a new window.

So, a single-chamber double-glazed window is suitable for:

• . If you don't see the need to create warm loggia, you can safely install windows with the simplest double-glazed window.
• Dachas, gazebos, summer house. As a rule, such premises "come to life" only in the warm season. At this time of the year, increased thermal protection is not useful. A double-glazed window with one camera is enough.

• Warm climate. If you live where birds actively migrate in winter, then you do not need double-glazed windows with enhanced thermal insulation. However, if you live in a busy part of the city, you will have to think about soundproofing.

Double-glazed windows, in turn, are suitable for:

• Cold climate. Our regions are known for severe winters, sometimes even heating does not save people. Then windows come to the aid of people: a two-chamber energy-saving double-glazed window perfectly keeps the heat in the house.
• Nursery and bedroom. Peace and quiet should reign in the child's room and bedroom. Double glazing with two air chambers different widths and energy-saving glass will provide additional sound insulation and will not give any external conditions disturb your comfort. Read more about this in our article on.
• Balcony, combined with the room. In this case, the usual single-chamber double-glazed window is indispensable, because the zone former balcony will freeze.

You will make the selection process easier for yourself if you distribute, in order of importance, the functions that your future window will have to perform. Remember that a rational approach will help you find exactly what you need.

Sincerely,

In modern plastic windows double-glazed windows can be with two or three glasses. Therefore, double-glazed windows can be of two types - single-chamber and double-chamber. Each type of double-glazed windows can be different thickness. Glasses in these double-glazed windows can also be of different thicknesses. Most often, transparent polished glass with a thickness of four and six millimeters is now used. In addition, tempered, energy-saving, sun-protection, shockproof glass, etc. can be used in double-glazed windows.

Single-chamber double-glazed windows

Physicists have long calculated that the optimal energy-saving properties of any double-glazed window are best provided when the distances between the glasses are 10-16 millimeters. For larger or smaller distances thermal insulation characteristics double-glazed windows deteriorate either due to insufficient air space, or due to an increase in convective heat transfer in the space between the panes.

A single-chamber double-glazed window consists of 2 glasses, which are separated along the contour by a distance frame. The separator contains a filler made of silica gel, with the help of which moisture is absorbed and due to this, dry air is obtained inside the double-glazed window. The resulting gas chamber is sealed from the outside with polysulfide and butyl mass. This camera is the result of outside world does not contact in any way and is an excellent sound and heat insulator.

For those who are still deciding which is better - single or double glazing, you should know that single-chamber double-glazed windows have such advantages as low weight and low cost. Among the shortcomings, it should be noted that, compared to two-chamber, heat transfer is greater and less noise protection.

Double glazing

A double-glazed window differs from a single-chamber only in the number of glasses, spacers and, of course, cameras. Double-glazed windows provide significantly greater protection against noise, as well as increased thermal insulation, which is achieved by using gas chambers and glass of various thicknesses. Such double-glazed windows will allow you to significantly save on heating. However, these double-glazed windows have a large mass and cost. Increasing the weight of the window leads to faster wear of the fittings.

The choice of single or double-glazed windows most often depends on the characteristics of the room and required level transmission of light, noise and heat. If the structural characteristics of the building do not provide for large loads, then preference should be given to lighter and thinner single-chamber double-glazed windows. This type of double-glazed windows is most suitable for glazing balconies, cottages, industrial premises, and also for the device of partitions in the room.

It should also be remembered that the increased performance of double-glazed windows alone cannot guarantee high-quality filling. window openings. Much greater value has a professional installation work.

Difference between single or double glazing

However, there are effective glasses, and the thermal insulation of single-chamber double-glazed windows in them is equal in its properties to double-chamber ones. But, it must be remembered that in addition to preserving heat, windows must also protect against noise, in this case, two-chamber options benefit greatly.

Remember that in order for sound insulation to be effective, the distances between the glasses in the block must differ. That is, frames for double or triple glazing must be different in width.

If we compare a two-chamber double-glazed window with a single-chamber one, then a certain pattern is visible. If the thickness of single-chamber structures is 24 mm, then their formula is 4-16-4, where 4 mm is two glasses, and there is a distance frame of 16 mm between them. They are mainly put to save on windows and balcony doors, where there is already a glazed balcony or loggia, as well as in rooms where high sound insulation and thermal conductivity are not important.

A three-chamber double-glazed window is a "sandwich", which consists of four glasses, which are interconnected by frames. Three-chamber blocks are used in areas with a harsh climate or in very noisy areas of the city, next to the main highways, if necessary. reliable protection from noise.

When choosing single-chamber or double-glazed windows, one should think not only about such factors as noise insulation or thermal conductivity, but also about safety. Two-chamber windows have an additional distance frame that strengthens the plastic window itself. If we talk about the load on fittings or on the material of a house or apartment, now for the manufacture of windows the standards for their manufacture are increased and the load is distributed without loading the window opening.

IN Lately In double-glazed windows, window and door manufacturers have begun to use energy-saving or i-glass, as well as salari-glass. Due to this, the thermal insulation properties of even single-chamber double-glazed windows are improved, which in turn reduces the cost of the product.

All my friends and relatives have single-chamber double-glazed windows, we also installed them. Heat and sound insulation are excellent (windows overlook both the courtyard and the road with constant traffic). They did not overpay, they are quite satisfied with the result: warm, light and quiet. Probably, double-glazed windows are necessary for people whose houses and apartments face very noisy highways or in northern cities with a harsh climate.

Two years ago we replaced the old wooden windows in a private house on metal-plastic. Then we decided to take exactly two-chamber ones for greater heat saving. Their price suited us at the time. Of course, they have a sin to complain about sound insulation. But already this year, curtains and latches began to function poorly, as indicated in the article. But, as they say: "Nothing is eternal".

By personal experience successful operation in the apartment of single-chamber packages with i-glass and two-chamber with ordinary glasses, I prefer two-chamber. The thermal insulation of the latter due to two chambers is not inferior to single-chamber packages with energy-saving glass (i-glass), but the sound insulation will be an order of magnitude higher. Another such moment, from two-chamber it is better to choose packages with different distances between the glasses (there are also symmetrical ones). This will significantly increase the performance of their noise and heat insulation.

I prefer double-glazed windows, the price is reasonable, not much different from single-chamber windows, but good thermal insulation. After all, I live in Siberia and our winters are very severe.
