What double-glazed windows should be installed in modern plastic windows?

IN modern world comfortable housing is of great importance for comfortable life. The interior design of apartments should be perfectly combined with professional thermal insulation, which can provide climatic conditions most suitable for living.

For the high-quality performance of all these functions, plastic windows are of particular importance. The double-glazed windows with which they are equipped are of particular importance, since this glazing element can either improve or negate all the thermal insulation qualities of the structure.

Almost all dealers position their products based on the name of the profile system manufacturer. Although when speaking of Rehau or KBE windows, most consumers mean the entire window, and not its individual elements. The correct choice should involve a complete selection of the components that make up the windows.

Double-glazed windows and fittings are as important a component as the profile itself. These glazing elements must be selected based on the effect you expect from the glazing. For example, if you decide to reconstruct a balcony without significant insulation, an ordinary single-chamber double-glazed window will be enough for you. More expensive products in in this case will be irrational.

Conventional single-chamber double-glazed window

The design of such a double-glazed window in a plastic window is quite simple. It consists of two identical glasses, between which there is a distance. The glass thickness most often used for these structures is 4 mm.

In construction circles, to determine the glass unit in digital value It is customary to use the formula: first number, which denotes glass, second distance, and third again, glass. For example, 4-16-4 means that this window has a single-chamber double-glazed window with a glass thickness of 4 mm. Letters are sometimes placed next to the digital symbols, which indicate the filling of the double-glazed window. The latest technologies prove that the air with which these structures are usually filled is very ineffective for high-quality insulation, so such structures are filled with a variety of gases.

Another very important element of a double-glazed window is the filler and glue on which the glass is attached to the distance. This composition usually consists of two layers. The first is designed to ensure gluing and firmly hold the glass at a distance, and the second performs insulating functions and prevents the formation of cold bridges in the plastic window. The glass unit must fit tightly into the seating groove.

The distance can be made of a variety of materials. The main ones are plastic, aluminum and galvanized steel. In our country, the latter is used most often. The distance, in fact, represents a profile, which in the lower part is equipped with holes for collecting moisture. Silica gel or molecular sieves are most often used as absorbent materials. They are designed to absorb moisture and prevent the negative effect when windows fog up. The glass unit must be as tight as possible.

Double-glazed windows

Double-glazed windows have become most applicable in the last few years. Such designs consist of three glasses and two distances. Their popularity is explained by their excellent insulating qualities. Such double-glazed windows in plastic windows in Moscow can make any home as comfortable as possible and create an excellent cozy atmosphere, despite what is happening outside the window.

The use of these structures is fully justified in terms of investment. Saving on energy resources will help you, after some time, more than recoup all the costs of carrying out this work.

Energy-saving double-glazed windows

For high-quality energy saving, there are few profile systems of increased comfort that are used in plastic windows. Double-glazed windows of such designs must also have all the necessary functions to increase insulation against heat loss.

Energy-saving double-glazed windows come in various types and manufacturing methods. All technological features in the manufacture of such structures are aimed exclusively at increasing heat-repellent functions.

The first method for making such systems is to fill one of the chambers with argon or a similar gas. This significantly increases not only the thermal insulation functions, but also significantly improves the sound insulation in the apartment.

The second method of creating energy-saving double-glazed windows for plastic windows in a house is to install energy-saving glass, which is designed to let the sun's rays into the room and not let heat out back.

There are two methods for making such glass. k-glass is made by depositing solid tin oxide particles. This happens during the smelting process. i-glass, in contrast, is produced by vacuum deposition onto the finished product. The spraying composition contains particles of silver and dielectrics.

Impact-resistant double-glazed windows

For residents of the first floors, there is another important function that windows should have. Double-glazed windows should make it difficult for potential thieves who want to break into your apartment. It was for these purposes that it was produced the new kind glass called triplex. Its design, in fact, consists of two ordinary glasses, between which a special film is fused. It is extremely difficult to break such glass the first time, since upon impact only cracks appear on it. Even when broken, it does not burst, but shatters into tiny fragments. This product can stop the villains who decide to break into your apartment, and can create enough noise so that the neighbors have time to call the right person. This will allow you to leave home for a long period without fear for your property.

The glass unit is the most important and at the same time the most fragile part. Therefore it must be
high quality: without impurities, bubbles and streaks. With us you are sure of the result.
We purchase large quantities exclusively with improved parameters

The glass unit occupies 80% of the window area. What he really is? This is a design
of two or three glasses that are hermetically sealed together. Hollow frames
made of plastic, air chambers are created between them, which keep them in the room
warmth and protection from street noise

Self-cleaning

• The surface facing the sun reacts to ultraviolet rays
  and with their help breaks down organic dirt.
• Inside there is a thin transparent film about 15 nanometers
  from titanium oxide. Thanks to it, dirt does not stick to the surface

Noiseproof

• Increasing the thickness of the glass unit due to different widths for better
  noise reduction.
• Increasing the distance and filling the air chambers of double-glazed windows

Impact-resistant varieties

• Triplex - several layers of the same or different thickness and type
  glasses connected with a special film or resin
• They have increased strength and resistance to external influences
• Even if broken, the fragments will remain glued to the film layer
  or polymer resin. This seriously reduces the risk of injury or cuts.

Dear clients of the First Window Company!

On this page you can learn about what types of double-glazed windows there are and what important role they play in the operation of plastic windows.

A double-glazed window is the main element of a plastic window, because it realizes the main purpose of the windows - to let light into the room. Structurally, a double-glazed window consists of 2 or 3 glasses located parallel with a small (8-24 mm) gap, connected around the perimeter using a metal frame and special sealants. The chambers formed between the glasses are filled with dried air or inert gas. Compared to conventional glazing, a double-glazed window has clear advantages: it has higher heat and sound insulation rates; The glass in a double-glazed window does not fog up or become dirty from the inside.

A double-glazed window with two glasses is called single-chamber, with three – two-chamber. The main characteristics of double-glazed windows - heat transfer resistance and the degree of sound insulation depend on the number of chambers, their filling, the thickness of the double-glazed window and the brand of glass.

For windows facing the street, it is recommended to use double-glazed windows with a heat transfer resistance of at least 0.45 m2*0C/W, because A glass unit with lower values ​​of this coefficient condenses moisture in frosty weather and the windows fog up. This requirement (0.45 m2*0C/W or more) is satisfied by double-chamber double-glazed windows with ordinary glass (grade M1) with a thickness of 32 mm or more or single-chamber double-glazed windows with a thickness of 24 mm or more with one energy-saving glass of grade K.

The distance between the glasses in a double-glazed window affects its thermal insulation properties only up to a certain limit, after which this influence becomes insignificant. So, for example, when the distance between the glasses of a single-chamber double-glazed window increases by one and a half times - from 16mm to 24mm, the coefficient of heat transfer resistance (CTR) increases by only 0.02. Therefore, it is inappropriate to strive to purchase “thick” double-glazed windows; a distance between the glasses of more than 20 mm only makes the double-glazed window heavier and more expensive, without improving its heat-insulating properties.

To a much greater extent, the heat transfer resistance is influenced by the use of energy-saving glass in a double-glazed window. For example: a single-chamber double-glazed window with a thickness of 24 mm has CST = 0.32, and a similar double-glazed window with energy-saving glass of grade K has CST = 0.53, i.e. more than one and a half times higher. Energy-saving glass grade I increases the CST even further.

Energy-saving glass is approximately 2 times more expensive than regular glass, but the difference in price quickly pays off due to savings on heating. In addition, energy-saving windows make it possible to lighten the window structure and thereby reduce the load on the fittings, extending their service life, and prevent condensation deposition and fading of furniture and wallpaper. Externally, such glass does not differ from ordinary glass; to find out whether a double-glazed window contains energy-saving glass, you need to light a match and look into the double-glazed window at the reflection of its flame at an angle of 45 degrees. The number of reflections will be equal to twice the number of glasses, and one of the reflections, corresponding to the surface with an energy-saving coating, will be different in color from the rest.

For maximum protection from street noise, you should choose double-glazed windows with different glass thicknesses (the thickness of the outer glass is 6mm) and with different distances between them. A glass unit of this design helps to avoid the phenomenon of resonance. Triplex glass has the best sound insulation - two glasses with a layer of noise-proof resin.

For lower floors, double-glazed windows with tempered outer glass are recommended, which is difficult to break - it is 5 times stronger than usual. You can also use triplex glass, which cracks after breaking but remains in place. The strength of the double-glazed window will also be increased by solar control film glued to the outer glass to reduce the amount of solar energy entering the room. If the glass does break, then the entire glass unit must be replaced; it is impossible to change the glass in it. The design of modern windows allows you to replace a double-glazed window without the need to dismantle the window.

Recently, double-glazed windows with colored glass have become popular. Colored glass reduces the penetration of solar heat into the room, but at the same time they themselves overheat, which can lead to their gradual destruction. In the southern regions, it is recommended to use double-glazed windows with colored glass that has been tempered and specially treated with edges. Such double-glazed windows need to be installed with the colored glass facing outwards, otherwise in hot weather it will heat up and “heat” the room.

According to SNIP, double-glazed windows cannot be installed at outdoor temperatures below 15 degrees. frost. The air temperature in the room should not fall below +5 degrees C.

- Double-glazed windows. What it is?

Nowadays, most buildings have metal-plastic windows installed. An integral part Any metal-plastic window is a double-glazed window. Many of us do not see the difference between a metal-plastic window and a double-glazed window, but these are different things. In our article you will learn the difference between the first and second, we will understand the production technology, and we will learn the types of double-glazed windows.

A double-glazed window is a block of several glasses. The glass is connected hermetically to each other using a special spacer frame, as well as internal and external sealants. As a result, a closed cavity is formed; it is filled with gas, such as argon, krypton, or simple dried air. The glass unit design was patented in 1865. Double-sealed double-glazed windows have been produced since 1970 to this day. Since that time, this has probably been the most popular type of glazing in buildings.

It is the double-glazed window that is responsible for the main characteristics of windows, namely thermal insulation, sound insulation and appearance window.

There are three types of double-glazed windows: glued, soldered and welded. In most cases, glued double-glazed windows with single or double sealing are used in practice.

The properties of a double-glazed window usually depend on two factors:

Design features

Type of glass from which the glass unit is made

Double sealing retains gas in the space between the glass, thereby increasing the heat and sound insulation of the room, prevents the accumulation of moisture and dust and, accordingly, does not impair the illumination of the room.

The glass unit structure consists of:

Distance frame with dryer

Sealant (internal and external)

Its service life depends on how well the glass unit is made.

The most important element of a double-glazed window is glass. Almost any type of glass is suitable for the production of double-glazed windows, it all depends on the wishes of the customer. The following types of glass are used in our country:

Tinted (sun protection)

Tempered (extra strong)

Colored (decorative)

Energy-saving (low-emissivity) glass is very popular around the world. Distinctive feature The advantage of such glass is that one side of the glass is covered with a thin layer of metal, due to which thermal radiation is reflected, so the room does not heat up in summer and does not cool down in winter.

Distance frame. The design of the spacer frame is hollow inside and has special diffusion holes. A dehumidifier is placed inside. The role of a desiccant is played by molecular sieves or silica gel. Its purpose is to quickly remove accumulated condensation and moisture between the glasses. It is usually made of metal (aluminum, galvanized steel), but for greater reliability plastic is used.

Sealant. It is impossible to imagine a double-glazed window without the use of sealant. It ensures structural strength and prevents moisture from penetrating into the structure. Usually double sealing is used. Internal - from the inside of the glass unit, and external - from the outside.

The process of making double-glazed windows is quite simple. The first step is to cut the glass into pieces of the required size and wash it. Afterwards they are secured in a spacer frame and pressed with a special press and sealed. During the manufacturing process, it is important to adhere to the requirements of the technological process, to maintain the accuracy and thoroughness of the assembly of the structure.

In practice, single-chamber or double-glazed windows are most often used. It's better if it's a two-chamber one. But a single-chamber double-glazed window will reduce heat loss and reduce noise levels compared to conventional glazing.

So, when choosing metal-plastic windows for yourself, Special attention Pay attention to what kind of glass they are made of.

- Double-glazed windows made using “Thermal Mirror” technology.

A double-glazed window is the heart of a window, which is subject to serious requirements, without knowledge of which it is impossible to select the right double-glazed window depending on its installation location!
Single-chamber double-glazed window.
This system consists of 2 glasses, distributed over a fixed space using distance markings.
Manufacturing a double-glazed window involves using glass of different thicknesses (4.5 - 6 mm). All single-chamber double-glazed windows are calculated using a special formula.
Double-glazed window.
Designed to increase thermal parameters and reduce noise insulation. A double-glazed window consists of 3 glasses, and the spacer frame is assembled into one “sandwich”.
Formulas for calculating double-glazed windows may be different. Glass (4 - 6 mm) with a layer inside (6 - 16 mm), although maintaining all distances is not necessary, because such double-glazed windows are produced with special cunning! Taking into account the energy-saving properties of the product.
A high degree of noise insulation is certainly achieved with the help of double-glazed windows. It is recommended to purchase multi-chamber double-glazed windows with different distances between the glasses, as they will effectively eliminate noise outside the window. In other words, frames in double and triple glazing are provided in different widths.
A highly qualified manager who cares about a potential buyer will always help in making the right choice. A wise choice will help preserve heat, save significantly on heating and reduce noise.
The quality of a double-glazed window directly depends on the type of glass used in it.
Energy-saving glass - has a special coating with selective infrared rays. Thin spraying does not change the transparency of the glass. This type of glass is used to achieve effective heat-insulating properties. They produce glass with both soft and hard coatings. For improved heat-saving properties, a soft coating is used, which is not resistant to moisture; open storage is not appropriate here. Installation of such glass requires additional equipment. Hard coating has no disadvantages, which is why it is used in the production of double-glazed windows.
Tempered glass is produced by heat treatment. As a result of processing, such glass has mechanical and thermal wear resistance.

-Selection of double-glazed windows

A double-glazed window is an integral part of the plastic window structure, which is installed in the window sash. Typically these are two or three sheets of glass with a gap between them, which are hermetically sealed with an absorbent material. Double-glazed windows are distinguished by their heat-retaining and noise-insulating properties different quality depending on the type of glass unit.

Single-chamber double-glazed windows have two glasses separated from each other by a special frame with a material that absorbs moisture and prevents condensation. The internal space insulates from noise and temperature influences. Single-chamber double-glazed windows in residential areas can accumulate condensation and icing, which can cause cold to penetrate into the room. Therefore, double-chamber double-glazed windows or single-chamber double-glazed windows with a heat-saving coating are preferable for housing.

A double-glazed window has two internal spaces or chambers, and three glasses. Its protective functions for energy saving and protection from atmospheric influence significantly increase in comparison with the first one, and its use is economically quite profitable, and it is suitable in any temperature regime.

Glass can be transparent, tinted, with the addition of metals in its composition, with a mirror coating, with an energy-saving coating, triplex glass, armored glass.

Double-glazed windows come in various types: energy-saving, safe, noise-proof, sun-proof, and, at the owner’s request, they can combine several of these advantages in one, subject to certain financial capabilities.

Energy-saving double-glazed windows can have a hard (“K-glass”) or soft (“i-glass”) coating. The latter retains heat one and a half times better, and the demand for it is constantly growing. The coating of this type of glass consists of metal oxide and silver, due to which long waves of heat are reflected and remain inside the space, and sunlight passes through the coating unhindered.

Noise-proof double-glazed windows will be of better quality depending on the thickness and number of glasses, and the width of the space between them. A large number of glass in a double glazed unit increases the resonance of the glass and reduces sound insulation. Taking this into account, thickened glasses are installed, different from each other in thickness (up to 30%) in one double-glazed window, with chambers inside of different widths. Sulfur hexafluoride inside the chambers, which differs in resonant frequency from the atmospheric space, and glass lamination improves sound insulation.

Safety double-glazed windows include triplex, tempered and reinforced glass structures. Both regular and low-e glass, with a soft or hard coating, are suitable for tempering. If a safety glass unit is destroyed, then its parts are held on to the triplex layer as part of the package or crumble into smooth, safe grains if the glass is tempered. Tempered glass increases the strength of glazing by 4 times, and reinforced glass makes the glazing fire resistant.

Solar control double-glazed windows are produced in a wide range. They perfectly perform a sun protection function indoors, reduce the effect of sunlight on fatigue, and give the room extraordinary lighting and appearance. These double glazed windows are manufactured using painted different colors glass A double-glazed unit may include glass with heat-absorbing properties, glass that transmits or reflects ultraviolet light, reflecting other shades of color, diffuse or patterned glass with an organic lavsan coating. Such double-glazed windows will emphasize architectural features and the style of the room.

The choice of a double-glazed window depends on the customer’s requirements, but a double-glazed window for any purpose, first of all, meets high international standards and quality with an unusually large assortment of glasses.

A double-glazed window is the main transparent part of the window structure, separating the room from the street and consisting of two or three sheets of glass. The noise and heat insulating ability of the window as a whole depends on its features.

Features of double-glazed windows

It is customary to distinguish between one-, two- and more-chamber double-glazed windows. In this case, a chamber is understood as a completely sealed space, limited by two glasses and filled with an inert gas, mainly argon or air dried using a special technology.

A single-chamber double-glazed window is a structure of two glasses, and a double-chamber one is made of three. At the same time, the distance between them and, accordingly, the width of the glass unit as a whole may also differ. It is provided by spacer frames and can range from 6 to 36 mm, with a width of no more than 20 mm considered optimal.

The degree of heat protection and noise insulation depends on:

• number of cameras;
• air gap thickness;
• type of filler (gas or air);
• properties of glasses.

A dry air or gas layer increases the insulating properties of glass, so a two-chamber design with an optimal chamber width can provide maximum thermal protection and noise insulation in comparison with a narrow single-chamber option. It should be understood that the additional chamber creates additional load on the hinges, and therefore requires the use of more expensive and high-quality fittings. Typically, two-chamber structures are chosen for windows of residential buildings and insulated balconies or loggias; single-chamber structures are installed on ordinary balconies and loggias when there is no need for additional insulation and sound insulation.

Types of glass and their properties

In the manufacture of double-glazed windows, in order to ensure special performance characteristics, they use different kinds glass We list only the most popular of them.
