From the article you will learn:

The rational use of natural resources is very important today all over the world, therefore the introduction of heat-saving technologies has great importance... Energy-saving devices and energy-efficient materials used in the arrangement of houses and apartments can significantly reduce the consumption of energy sources such as gas and electricity, which saves the family budget.

Energy-saving technology can be used both in construction and in repairs. Even a house that was not originally designed for such technologies can be upgraded. For example, a competent window design can reduce heat loss several times, and if we take into account that the glazing area can reach 20-30% of the area of ​​the room, and heat loss through light-transmitting structures can be up to 40% of all heat losses at home, the benefit from the use of heat-saving windows is obvious ...

Over the past half century, the window industry has taken a huge step forward. The first windows were simple wooden frame with one, rarely two layers of glass - their thermal conductivity was high, they were prone to drying out, rotting and subsequently required additional insulation. Double glazing provided better protection from the cold, air gap between the glasses reduced thermal conductivity by almost half, but still this design was far from ideal.

Further development led to the emergence of multi-chamber sealed bags filled, as a rule, with argon or krypton. Such windows not only perfectly protected from the cold, but also better resisted heat leaks from the room.

From the point of view of the laws of physics, the work of a heat-saving window can be explained as follows. In nature, heat can propagate as follows: heat conduction, convection and radiation. When window frame The main heat losses are due to heat conduction and convection - cold air from the street cools the glass, and it already cools the air in the room. An emission layer 5–7 mm thick appears on the glass surface. Therefore, it is necessary to exclude or reduce the influence of air in the heat exchange between the glasses.

For this, a multi-chamber design of a glass window unit and filling of voids with an inert gas are used. Argon has a lower molecular speed than air, so the speed of heat propagation from wall to wall will also be lower. The distance between the glasses should also not be less than 15 mm in order to exclude emission heat losses, while one of the glasses can have a special coating of silver oxide to reduce heat radiation, while sunlight passes unhindered. It is also important to use high-quality window seals that do not lose their properties over time. Such windows are considered to be heat-saving. Most often they are made of PVC ( mass production), less often made of wood (premium segment).

What are the types of heat-saving double-glazed windows.

The most effective and widespread are windows with two or more chambers; the distance between the glasses is different to save more heat. The glass used must also have a number of requirements: thickness - 4 mm, the thinnest layer of metal oxide can be applied to one surface, preventing the penetration of ultraviolet radiation, but transmitting infrared light. In this case, the heat from the room is retained by this layer and returns back.

Depending on the application technology, two types of glass are distinguished:

• I-glass, a soft coating provides the necessary level of protection and thermal conductivity, but the service life of such glasses is limited - no more than 10 years, which can be a significant drawback in certain conditions;
• K-glass, the thermal protection coefficient is one and a half times lower, but the service life, due to the harder coating, can reach several decades.

Such glasses show themselves well in winter, significantly reducing heat loss, however, in summer time additional technology is required to reduce heating. It is about reflective glasses that reflect the sun's rays and prevent objects from heating in the room. Ordinary tint can be used, but such glass will become very hot and distort sunlight, although the heat will undoubtedly decrease. To achieve maximum effect, it should be that combine all these technologies.

The advantages of such heat-saving windows are obvious:

• 100% UV protection;
• high thermal insulation and the ability to return up to 90% of the heat to the room;
• lack of fogging and maintaining an optimal microclimate in the room;
• reducing the cost of air conditioning and space heating;
• reducing the weight of the entire structure of the glass unit by up to 1.5 times, while the service life of the fittings increases.

With such structures, the apartment will be warm in winter and cool in summer.

For the production of energy-efficient windows in the IZOLUX company, manufacturers can order heat-saving insulating glass units ClimaGuard ® 4 mm thick with protective layer based on silver, as well as bags with I-glass 4 and 6 mm. Both are filled with argon.

Advantages of heat-saving insulating glass units

Durability and reliabilityWindow systems with heat-insulating glass units are lighter and less load on the fittings, extending its service life. Low-emission spraying is maintained throughout the entire operating time of the system.

Effective thermal protection in winterThe design insulates heat much better than the standard one, although it weighs less. A package with one chamber of two energy-efficient glasses is 1.5 times lighter than a standard one and retains 25% more heat in the room.

Comfortable microclimate in summerIn the summer heat, the packets reflect heat waves outward and keep the room pleasantly cool.

There are two sources of heat in the room. First - solar radiation coming into the windows from the outside - ultraviolet, visible light and short IR waves; the second - heated objects and heating devices in the room, which emit long infrared waves. Help prevent heat loss I-glass with low-emissivity coating reflecting infrared radiation into the room. The ion-coated glass is installed first so that the sputtering is located inside the glass unit. Silver ions on the surface of the heat-efficient bag create a mirror effect. In contact with heat waves from heating devices, they direct the radiation back. As a result, the heating intensity can be reduced by up to 50%.

Energy packagesClimaGuard ®Solar multifunctional. They solve two problems: in winter they keep heat in the room and in summer they protect the room from the sun. One layer of their coating reflects heat waves from heated surfaces into the room, the other keeps up to 60% solar energy... Silver coating does not violate the transparency and optical properties of glass, helps to save on heat supply, eliminates fogging of windows.

Hello!

Received an e-mail from one of the readers with a question about energy-efficient double-glazed windows. They have in kindergarten replacement of windows is planned, they decide which is better to install.

Since it is cool in the children's room all year round, parents want to make the conditions more comfortable.

First of all, he was interested in the ratio of price and quality, that is, how much better such windows retain heat and how much higher their price is.

I am writing about all this especially for him and other enterprising parents who want to give their children all the best.

Welcome!

Energy-efficient double-glazed windows are the number one choice among consumers today.

They represent a certain type of glazing that perfectly retains heat in the room.

Unlike conventional glass units, insulating glass units with energy-saving glass are made of special glass, on top of which a certain low-emission coating is applied.

This allows the solar energy with short waves to pass unhindered directly into the interior of the room, and the heat fluxes tending outward to be reflected freely, thus preserving heat.

There are several types of heat-saving windows:

1. Energy-saving double-glazed windows with argon. They contain a special gas that creates a certain pressure inside the system and prevents heat from escaping to the outside.
2. Energy-saving single-chamber double-glazed window. Has one camera.
3. Energy-saving double-glazed window. Presented by two cameras, respectively.

Production implies the use of several types of glasses in the process of their creation:

• I-glass with improved energy-saving effect, absolutely transparent;
• K-glass with a metal oxide on its surface has more low degree transparency.

Depends on the type of glass used in the process of their manufacture and the number of chambers. They are determined by the type of glass unit and the resistance to heat transfer.

Drawing an analogy with a conventional single-chamber window, it can be noted:

- that the level of its resistance to heat transfer is - 0.32,

- energy-saving single-chamber - 0.59,

- two-chamber conventional - 0.47,

- two-chamber energy-saving - 0.64.

Thus, we can say that, in contrast to the usual one, the energy saving package is 1.5 - 2 times warmer.

Before checking an energy-saving glass unit, it is necessary to check the presence of such an important indicator as the marking, which indicates the type of glass used, the number of chambers and the level of energy saving.

This is a prerequisite indicating their high level, quality, practicality and durability of performance.

Note!

Single-chamber or double-chamber package with energy saving function, saves about 38 -40% more heat than conventional ones metal-plastic windows at the same cost!

Many manufacturers, unlike us, offer their customers deliberately inflated prices. Our price is the personification of democracy and acceptability for various categories of the population.

Or you can send a request for calculation to our managers and they will call you back and announce the cost of your window.

According to research, such windows pay off in 1 season !!! After that, you get net savings for the rest of the time.

The energy-saving glass unit purchased from us differs in:

• high quality;
• reliability;
• practicality;
• aesthetics;
• a high degree of functionality;
• excellent heat-saving properties;
• good fittings from the world's leading manufacturers.

We will provide you with a high level of service, as much as possible fast production windows and long warranty period.

Therefore, modern manufacturers are trying in every possible way to make their window as energy-efficient as possible.

For this, double-glazed windows with energy-saving glass are used in the windows - i-glass.

Energy saving characteristics

The characteristic of energy saving is the emissivity of glass.

Emissivity (emission) is understood as the ability of a glass surface to reflect long-wavelength thermal radiation invisible to the human eye, the wavelength of which is less than 16,000 (Nm).

The surface emitter (E) determines the emissivity of glass (for ordinary glass it is> 0.83, and the emissivity of selective glasses is less than 0.04) and, therefore, the ability to "reflect" back into the room thermal radiation.

The reason for the appearance of radiation lies in the movement of free electrons of atoms located on the surface of the glass, and the density of moving electrons.

Useful advice!

The surface emissivity (E) of ordinary glass is> 0.83, and the emissivity of selective glasses is less than 0.04

Not all metals are well conductive electricity, possess the property of reflecting long-wave thermal radiation. Consequently, the lower the emitter, the less loss heat. In this case, glass with an optical coating having an emitter value of E = 0.004 reflects back into the room over 90% of the thermal energy leaving through the window.

That's why most of window manufacturers in Russia today use energy-saving double-glazed windows and their market share is constantly growing.

Difficulties with transportation and work with i-glasses associated with their design features, led to the fact that in the world, as a rule, only large, specialized firms are engaged in the production of energy-saving windows.

Energy-saving windows with i-glass are also offered by the company "Okna-Etalon". By purchasing it, you get the highest possible efficiency from the money spent!

i-glass is a low-emission glass with a multilayer coating (including silver) applied by plasma spraying in a vacuum.

This is a "soft" coating.

A sheet with such a coating should only face the inside of the glass unit. I-glass is produced by vacuum deposition and is a three-layer (or more) structure of alternating layers of silver dielectric (BiO, AlN, TiO2, etc.).

The application technology requires the use of high-vacuum equipment with a magnetron sputtering system. Low-emission i-glass during the heating season "returns" to the apartment up to 90% of the heat waves emitted by heating devices.

In summer, it reflects the thermal, infrared (IR) part of the solar radiation. As a result, the room becomes warmer in winter and cooler in summer.

I-glass has improved thermal performance. For example, for outside temperature-26 degrees and indoor temperature +20, the temperature on the surface of the window inside the room will be +5 degrees for an ordinary glass unit, and +14 degrees for an energy-saving one.

Advantages of using insulating glass units with energy-saving I-glass:

• i-glass reflects long-wave heat rays towards their emitter (that is, in winter towards an apartment where heating devices work, and in summer towards a street where stones, asphalt, etc. heated by the sun are located), which significantly reduces heating costs in winter and air conditioning in summer. In other words, the coating leaves heat where there is more.
• The thermal insulation capacity is significantly higher compared to a two-chamber glass unit. Thus, in any climatic zone thermal comfort in the room is achieved by using double-glazed windows with energy-saving glass. The effect - "blowing from the window" is eliminated.
• The temperature on the surface of the glass unit is higher than on the surface of ordinary glass, which reduces the likelihood of condensation on the glass.
• i-glass prevents fading of upholstery and interior items. In this case, the transparency is similar to that of ordinary glass.

Compared to ordinary glass, i-glass can provide truly incredible savings.

On average, a private house has about 4 windows, with total area about 9 sq. m. Total savings for heating season will be: 2070 kW, which is equivalent to 1.5 tons coal for the heating period and will save about 6,000 rubles in the first heating season.

When choosing new windows, the buyer first of all looks at whether they are made of plastic or wood, not taking into account the fact that this plays a small role in energy saving, because the materials framing the translucent structure make up an insignificant part in the window.

But the skylights, which make up the bulk of the area of ​​the glass unit, account for more than 40% of all heat losses of the building. The use of ENERGY-SAVING GLASS will help to keep the heat as much as possible, preventing it from leaving the room through the window.

Energy-saving double-glazed windows have a number of advantages not only over single-chamber double-glazed windows made of ordinary glass, but also over two-chamber ones, consisting of 3 of the same glass. Why are energy-efficient insulating glass units better compared to double-glazed insulating glass units made of three conventional glass panes?

1. The power package provides 30% higher resistance to heat transfer - about 0.61 m2K / W;
2. A single-chamber double-glazed unit is one third lighter than the commonly used double-glazed unit, i.e. is one third less material intensive;
3. Such a glass unit is more acceptable for our climate;
4. In an energy-saving glass unit, a significant reduction in the load on fasteners and hinges helps to reduce their wear and, as a result, increases the durability of the frame structure;
5. A double-glazed unit with energy-saving glass is actually cheaper than a two-chamber unit by 20 - 30%;
6. The energy package significantly limits the passage of ultraviolet rays into the room, which prevents the fading of furniture and window curtains.

Often, when buying windows, we allow ourselves to save money by choosing cheap, "old" technologies that are not improved and not adapted to our weather conditions.

We gave an example of a technology that is currently the most suitable for the buyer in terms of price-quality ratio.

Our company successfully works with this technology and in its production uses only high-quality glass "ClimaGuard N" "ClimaGuard Solar", "Sun-Guard High Performance" from the world famous company "GUARDIAN" USA, which has its glass factories all over the world.

One of issues of concern consumers are faced with the question of defining glass with an energy efficient coating.

Useful advice!

One of the most popular and readily available methods of testing is holding fire to glass, the color of the reflection of which will change from yellow to red.

A red flame indicates an energy saving coating. This method is optional but not basic.

The most reliable and professional way to determine an energy-saving coating in glass is a special electronic device that detects both the presence of the coating itself and the side on which it is applied, which cannot be done with the above method.

What kind of glass "ClimaGuard N"?

1. Heat-saving glass with silver dusting;
2. Effectively retains heat indoors in winter;
3. Reduces heat loss;
4. Increases the temperature of the inner glass by 6 degrees (center temperature, calculated value);

Produced in Germany, Luxembourg, Russia, Poland, Hungary. The technology of vacuum magnetron sputtering allows the deposition of transparent layers of silver atoms and silicon nitride (to protect silver).

Note!

With the help of silver on glass, we get the same effect in the room as in a thermos - the heat stays inside, and does not go into the atmosphere. Heat loss when installing such glass is reduced by 15 - 20%.

What is ClimaGuard Solar glass?

It is a multifunctional glass that protects against heat in summer and cold in winter. Super-thin layers of metals applied to the glass make it possible to keep it as transparent as possible.

A special coating of silver and other metals creates the effect of a transparent filter that allows visible light to pass through, but significantly reduces the penetration of solar heat into the house in summer and heat leakage in winter.

The silver coating on the ClimaGuard Solar glass reflects long-wave thermal radiation, for example from heating devices, inside the room, preventing it from going outside.

• "ClimaGuard Solar" glass provides effective protection from the sun, which helps to significantly reduce the cost of air conditioning (solar factor 42%);
• A high coefficient of resistance to heat transfer (0.65 m2K / W) allows you to reduce the cost of heating a room in the cold season (heat savings - up to 78%);
• Visually transparent glass (no color distortion);
• ClimaGuard Solar glass is preferable to use in projects where energy saving, sun protection and good natural lighting of premises are important.

What kind of "Sun-Guard High Performance" glass?

Peculiarities:

1. Sun protection properties. Multifunctional glass "Sun-Guard HP" Capable of filtering the sun's rays by wavelength. The bulk of the thermal radiation is reflected (blocking solar (thermal) radiation), and natural light penetrates the room almost without obstacles.
2. Thermal insulation properties. Multifunctional glass "Sun-Guard HP" provides high thermal insulation (low coefficient of thermal conductivity) in a glass unit, where the second glass is ordinary transparent.
3. A wide range of shades and colors.
4. Benefits for end users. The use of multifunctional glass "Sun-Guard HP" reduces the cost of air conditioning and heating of the building without loss of illumination and color rendering.

Improved thermal insulation increases the surface temperature of the glass, which reduces the circulation of cold air and the likelihood of condensation on the inner glass in cold climates, and also reduces condensation on the outer glass of the facade in hot and humid climates.

You can choose any design, but we always remind our customers that when the right choice You will not only avoid heat loss and save heating costs, but also drastically reduce the penetration of annoying noise from the street.

The most important thing is to ensure the durability of the structure with your choice while maintaining all its original properties.

Today in our country is preserved centralized system heat and power supply. Mostly this is a heat supply system, in which about 65% is the share of CHP.

The rest of the share is accounted for by boiler houses and autonomous systems heating.

Tariffs for heat and energy resources have a tendency of constant growth, and therefore efficient work heating networks and a significant reduction in heat loss is considered as a strategic task.

In this regard, the problem of energy conservation has become one of the most urgent for our country. That is why manufacturers plastic windows solve the issue of keeping warm in the room by using energy-saving glasses.

It should be noted that the heat-shielding and energy-saving functions of the window are of great importance for the end user, because through the windows, depending on the type of house, heat loss occurs from 37% to 56% (apartments located at the end of the house).

Areas with a red background are “hot” areas through which heat is escaping most intensively:

• walls ~ 30%
• roof ~ 14%
• floor ~ 12%
• windows ~ 44%

100% of the living space of 4 5-storey buildings accounts for approximately 12-16% window openings through which heat loss in modern living quarters averages about 40%.

Useful advice!

Heat loss through old wooden windows is about the same as heat loss through walls. It turns out that heat losses occur through the windows through cracks, leaks and during ventilation of the premises.

German experience

So in Germany, in order to reduce heat loss, a massive reconstruction of buildings was carried out, namely walls, facades and replacement of windows.

After carrying out an analysis associated with calculations to reduce heat loss, the result showed the following:

- heat loss through the walls was reduced by 73%,

- thermal radiation through windows by 62%,

- heat loss during air exchange by 50%.

Similar calculations were carried out in our country for the relative reduction in heat loss:

if we replace existing wooden windows with plastic ones, then in terms of average cost thermal energy from CHP to middle lane Russia, the savings for an average apartment will be about 3 thousand rubles for the heating season. Of course, the figures are approximate, and the tariffs for heat carriers differ even within the same region.

Here are some more examples: in Moscow during reconstruction panel houses simultaneously with the insulation of the facades, windows are also replaced. The energy saving program in Moscow plans to install windows with energy-saving double-glazed windows.

This is beneficial because it solves the problem of eliminating significant heat losses. At the same time, the appearance of the facades of houses is preserved after the reconstruction as a result of the unauthorized installation of windows by residents.

In the city of Chelyabinsk, at the end of 2009, a project was carried out to install individual heat metering devices in two multi-apartment panel buildings.

The results showed the residents' desire to save money, since this immediately began to affect the bills for heat carriers. They began to regulate the temperature with a thermostat on the battery, and not with a window.

This means that less heat was emitted from the windows into the atmosphere.

For residents of private houses and cottages, the following example can be given:

- experts have calculated that, windows country house medium-sized ones, equipped with double-glazed windows with energy-saving glass, save as much heat energy during the heating season as 300 kg of liquid fuel such as fuel oil or diesel fuel gives.

So what are energy-efficient glass and how do they help keep the home warm? What is the difference between energy-saving glass and simple glass?

To make it clear for an ordinary end consumer - on one side of the surface of energy-saving glass, a coating that is invisible to our eyes is applied, which is a kind of filter.

The coating prevents the release of long-wave thermal radiation (infrared waves) from heating devices and reflects it into the room. Thus, the heat is retained and does not escape to the outside.

Note!

Energy-saving glass has a metallic coating thickness of only a few tens of nanometers.

It is no different from ordinary glass and is absolutely transparent to our eyes. Energy-saving glass is used in the manufacture of double-glazed windows, since their operation requires complete tightness.

For the production of ordinary sheet glass, two methods are used: vertical - by pulling and horizontal - on molten metal.

When using the horizontal method, so-called float glass is obtained, which has excellent optical properties and high light transmittance. So it is used for the production of energy-saving glasses. On the polished surface of float glass, a coating of non-ferrous metals (mainly silver) or their oxides is applied by spraying.

Due to the phenomena of electrical conductivity and interference, such glass gains the ability to reflect heat waves in the infrared range and, thereby, reduce heat loss in the room.

Glass with such properties is also called heat-saving, low-emission, and selective.

The first definition speaks for itself.

The second definition is related to such a physical concept as the emissivity of a surface or emission. Emission of energy-saving glass is an order of magnitude less than ordinary glass, which is why it is called low-emission glass.

The term "selective" means that our glass transmits light and heat waves selectively and it turns out that in the summer heat, the use of energy-saving glasses will protect your home from the penetration of infrared sunlight that can quickly heat the air in the room, and in the cold season, on the contrary , the heat will be reflected from the heating devices into the room.

This means that in any weather the microclimate that is optimal for comfortable living will remain in the house. In regions with hot climates, it is recommended to use darkening low-emissivity glasses.

They have an even lower degree of transmission of sunlight, protecting in summer period a room from the heat that the sun brings. Such solar glass can have different color toning: bronze, gray, green, pink.

Currently, two types of coatings are used for energy-saving glasses:

• soft (Double Low-E), the so-called I-glass;
• hard (Low-E) or K-glass.

Energy-saving hard-coated glass (K-glass) is produced by applying a thin layer of oxides of some metals on the still hot surface of float glass directly during its manufacture.

On its surface by the method of chemical reaction at high temperature(pyrolysis method) creates a thin layer of metal oxides InSnO2, which is transparent and at the same time has electrical conductivity.

It is known that electrical conductivity is directly related to the emissivity (E) of the surface. Emissivity plain glass is 0.84, and for K-glass it is usually about 0.2.

This coating is particularly durable and therefore it is called hard.

K-glass, significantly reducing heat loss, improves the thermal insulation of the room and thereby reduces the cost of heating it. It is on appearance is no different from ordinary glass and has the same high light transmission. K-glass as part of a double-glazed window is turned by a low-emission coating towards the room.

It does not transmit long-wavelength thermal radiation from heating devices through the interwindow space.

Note!

Energy-saving glass with a soft coating (I-glass) is produced using a more sophisticated technology.

I-glass is a high-quality glass with a low-emission coating applied to one glass surface under vacuum conditions by cathodic sputtering in a magnetic field of metal-containing compounds with specified selective properties.

The float glass is coated with a layer of silver and titanium oxide as a secondary coating. It possesses the best characteristics in comparison with K-glass, in particular, higher light transmittance and lower emissivity.

It should be borne in mind that I-glass has low abrasion resistance (it can be easily scratched).

The use of double-glazed windows, which include I-glass, allows not only to reduce energy consumption for heating a room, but also to significantly increase its comfort.

However, due to the fact that its energy-saving coating is always located inside the glass unit, on operational characteristics this disadvantage does not affect.

So, what is it - an energy-saving glass unit? First, let's find out what a regular package is.

The product is a system consisting of two or three sheets of glass connected along a contour so that a hermetically sealed chamber with a layer of dried air is formed between them.

That is, double-glazed windows can be divided into three types by design:

• SPOR - single-chamber with a framing frame (the width of the framing frame shelf should be 15 (± 1) mm and the distance between the glasses can be 6, 8, 9, 10, 12, 15 mm);
• SPO - single-chamber (the distance between the glasses can be 6, 8, 9, 10, 12, 15, 16 mm);
• SPD - two-chamber (the distance between the glasses can be 6, 8, 9, 10, 12 mm).

There are double-glazed windows filled with air and noble gases (argon, krypton).

Thus, an energy-saving glass unit is a product that includes low-emission glass.

To understand how low emissivity glass works, it is necessary to understand the meaning of the term "emissivity".

Emissivity is a measure of a surface's ability to absorb or lose heat (E). It is accepted to evaluate the emissivity on a scale from "0" to "1" (from 0 to 100%).

A large value on the scale indicates that the surface is a good heat emitter (it loses heat quickly). A low value on the scale indicates that the surface is a poor heat emitter (it loses heat slowly).

Surface emissivity of ordinary glass = 0.9. The emissivity of the surface of the glass with low emission coating = 0.17. These coefficients show that ordinary glass has a high emissivity of 0.9 and therefore is a poor insulator because it quickly loses heat.

Low emissivity glass has an emissivity of 0.17, a very low value, it loses heat slowly, therefore it is a good insulator.

Advantages of an energy-saving glass unit

1. Effectively retains heat indoors in winter up to 60% (maximum energy saving characteristics)
2. Solar protection in summer (up to 34% of solar heat is reflected)
3. The likelihood of condensation on the windows decreases (the temperature in the window area rises)
4. Heating costs are reduced (electricity or gas consumption in winter is reduced by reducing heat loss)
5. Improves the microclimate (which provides, for example, optimal development indoor plants)
6. Cleans the room from germs (due to the transmission of ultraviolet radiation)
7. Visually transparent glass inside (no color distortion)
8. Protects interior details from fading

Comparison of the thermal characteristics of windows with energy-saving glass and with conventional double-glazed windows shows that a single-chamber double-glazed window with energy-saving glass is more efficient than a two-chamber double-glazed window.

Window manufacturers give a comparison at a temperature outside the window of -26 degrees and an air temperature inside the room + 20 degrees:

• Regular double-glazed window. The temperature on the inner glass is + 5 degrees.
• Double-glazed unit with K glass. The temperature on the inner glass is + 11 degrees.
• Double-glazed unit with I-glass. The temperature on the inner glass is + 14 degrees.

How to determine the presence of an energy-efficient glass unit?

If you bring a lighter or a candle to a glass unit and consider the reflection of the flame.

Then on ordinary glass both reflections of the flame will be the same - yellow, and on glass with energy saving, one flame will be yellow, as on ordinary glass, and the second flame will have a pronounced red tint.

Energy saving glass

They are both hard and soft coated and are widely used in many countries.

Their production technology is rather complicated and requires high qualifications from manufacturers. Therefore, in the world there are only a few large companies producing energy-saving glass in large volumes.

Until recently, the bulk of high-quality glass was imported in Russia. After the completion of the construction of the new Glaverbel production complex in the Klinsky district of the Moscow region, Russians were able to use domestic energy-saving glass in the glazing of their homes and offices.

So how better in winter keep your home warm with the greatest efficiency? The advantages of insulating glass units with energy-saving glass are obvious here. And their use, especially in the construction of private houses and cottages, can be very beneficial, provided modern systems heating and ventilation.

Heat-saving glass unit in wooden windows has spacer frames made with the use of plastic, which excludes the appearance of a "cold bridge", creating a thermal break. This design allows you to almost completely exclude freezing of the glass unit at the edges and significantly reduce the likelihood of fogging. Additional insulation windows are carried out by filling the chambers with argon and the use of low-emission energy-saving I-glass.

What is I-glass

I-glass is an infrared (thermal) mirror that reflects thermal radiation back into the room. At the same time, I-glass does not interfere with the passage of the visible light of the Sun into the room. Such glass is made by applying a thin metal film onto ordinary window glass. I-glass is installed in a glass unit with a film inside, so the glass unit can be easily washed without fear of damage to the coating.

Heat-saving glass - heat-saving (energy-saving) glass is called polished glass, which has a special low-emission coating of metal oxides

Heat-saving glass.

Currently, to create energy-saving glass units, two types of glass with different types of coatings are used: a hard (pyrolytic) coating - the so-called K-glassand soft (magnetron) coating - I-glass.

K-GLASS- high quality float glass with a resistant, transparent "metallic" coating (it consists of almost a dozen components, mainly metals). The coating ensures the passage of solar energy into the building (it is transparent, has no color and its effect on light transmittance and reflection is practically not noticeable), but significantly reduces heat losses through the window (this is what it is intended for). That is, the coating transmits short-wave solar energy into the room, but does not transmit long-wave thermal radiation outside (for example, from heater). In appearance, K-glass is similar to ordinary transparent glass. In double-glazed windows it can be installed both as external and internal glass. The first method allows you to keep warm in the room (to minimize heating costs, which is most important for Russian winters). The second - allows you to reduce the heat flow from the street to the room (very suitable way installations for countries with hot climates, to which we, unfortunately, do not belong - VK.).

I-GLASS. Soft cover(TOP-N) is applied by electromagnetic spraying, during which metal oxide particles are deposited on glass in a vacuum environment. Advantage this method consists in obtaining glass covered with a uniform "magnetron" heat-saving layer.

Technology of applying heat-saving coatings on architectural glass

A significant proportion of the heat used to heat buildings is lost as heat radiation through the glass. Elimination of this channel of heat loss is achieved by using heat-saving glasses that reflect thermal (infrared) radiation and transmit visible radiation

Energy saving (heat saving) glass.

The use of such glass in the construction of a glass unit can reduce heat loss by 15%. The sun's rays, penetrating into the interior of the room, give their energy to the objects in the room. Heated bodies become heat sources that emit heat waves in the infrared range. A special (low-emission) coating on glass has the property of reflecting waves in this very range, thereby preventing heat loss.

Heat-saving sheet glass (TOP)

Sale of flat glass from China is carried out by the Barnaul Glass Company.

As you know, 2/3 of the heat loss in rooms is due to radiation through the window glass to the outside, since glass has a high emissivity.
In order to avoid heat loss, heat-saving sheet glass is used. A special low-emission metal oxide coating is applied to the glass surface. This coating is colorless, its thickness is several hundred angstroms, therefore, externally, a window made of such sheet glass does not differ in any way from ordinary transparent glass.

Double-glazed windows with heat-saving (low-emission) glass

Replacement of all double-glazed windows with ordinary glass for energy-saving double-glazed windows provides heating savings on average from 20% to 35%! This is very important for our windy and cold Ural winters.

Modern heat-saving glass

Modern heat-saving glasses allow achieving a high value of the reduced heat transfer resistance Ro due to the use of high-quality coatings. But such glasses reduce the flow of solar heat into the room, since the total flow of transmitted energy also decreases.

One of the main advantages of heat-saving glass ClimaGuard N is an excellent value of R0 = 0.66 m2С / W (GOST 24866-99) combined with a high energy transmission capacity (g = 66%, EN 410), which allows the use of free solar energy to achieve an optimal thermal balance building.

About glass

Heat leakage through window openings in rooms is on average 40%, and part of the heat is absorbed by glass. In order to prevent heat from penetrating inside the glass, a special optical coating is used. Glasses are produced with "hard" coatings - K-glass, and with so-called "soft" - i-glass. Heat-saving glass (energy-saving) is mainly used in the production of insulating glass units.

Heat-reflecting and heat-saving glass

Heat-reflecting glasses are obtained mainly by applying a mirror metallized layer (by evaporation of metal and oxides in a vacuum, cathodic sputtering or chemical deposition from solutions). To obtain maximum reflection, the thickness of the resulting film is essential. Usually five layers are applied: four layers - metal oxide, the fifth layer - silver. Silver almost completely reflects radiation with a wavelength of A.> 760 nm. Mirror films can be colorless or colored.

Heat-saving glass allows to reduce heat loss from the room through the windows by approximately 35 ... 40%, which is very important in winter. Such glasses are called low-emissivity, thereby emphasizing their low emissivity from the outer surface.

Heat-saving glass

It is a type of glass designed to reduce heat loss due to thermal radiation. They are also called energy efficient.

Additional heat-insulating properties are associated with the application of a special coating on the glass, which ensures the passage of solar energy into the building, preventing long-wave thermal radiation from heating devices from leaving the room.

Low-emission (energy-saving) glass

The coating freely transmits short-wave solar energy into the room, while at the same time reflects long-wave thermal radiation, for example from heating devices, into the room, preventing it from escaping outside. (Therefore, sometimes glasses with low-emissivity coatings are called "selective glasses").

In summer, the heat-saving coating reflects the solar thermal energy with outside, preventing the penetration of heat into the room. The coating is several hundred angstrom thick, has the properties of a light filter, is transparent to the human eye, visually glass with a heat-saving coating, no different from ordinary transparent glass.

Novelties of low-emission architectural glass used for glazing of facades and manufacturing of translucent structures

Lowe mission glass has excellent energy saving properties. With excellent transparency, it transmits solar radiation on the one hand, and reflects infrared thermal radiation (especially long and medium waves) on the other. This was achieved by the technology of applying various metal coatings onto the glass surface.

Energy saving glass.

Heat loss through glass is made up of heat conduction, convection and heat radiation. The emissivity of glass is the main characteristic of energy saving. The emissivity of glass (emission) of glass is understood as the ability of a glass surface to reflect long-wavelength thermal radiation invisible to the human eye of a certain wavelength. The surface emitter determines the emissivity of the glass and, therefore, the ability to "reflect" back into the room thermal radiation.
