Now you can confidently say that plastic windows with inserted double-glazed windows are a complex design. In addition, they are expensive and in production, it means that prices for the end user are also rather big. So before ordering and acquiring a plastic window with a specific device, it should be carefully chosen that it is suitable for you in both its characteristics and material possibilities. How to choose a glass unit for an apartment - this question is asked by every person who decided to insulate and seal the window openings of their dwelling.
Note that the glass is not correctly called the entire design of modern plastic Eurocon, but only transparent glass filling.
Some recommendations and features
As a rule, single-chamber double-glazed windows have a distance between glasses of 12-16 millimeters, this indicator varies from 6 to 16 millimeters.
As a rule, professionals are not recommended to acquire and use such double-glazed windows in the apartment, in which the distance between the glasses is installed more than 2 cm. However, the experimental way is found that too much the distance between the glasses lowers the thermal insulation of the entire plastic window.
This means that the apartment will be colder, drafts will appear. In addition, a large distance between glasses in the design requires large production facilities in the manufacture. Accordingly, the price of such products grows in proportion to the distance between the glasses. So such packages do not justify such a high price set.
Before choosing a glass, you need to know its coefficient of heat transfer resistance R.
The norm for plastic windows directly overlooking the street, the value of the coefficient of at least 0.45 sq.m.
Standard plastic windows with double-chamber systems usually comply with this requirement. Even some single-chamber designs for plastic windows meet these requirements.

As a rule, in conventional devices, the glass thickness must be equal to at least 4 mm, and the air layer should be from 8 to 16 mm.
Nuances of arrangement. What is advised when choosing
With large windows there are certain difficulties in installing and maintaining them, but they look much more effectively than small ones.
If non-standard windows are required in your apartment or country house, it is necessary to consider the fact that the maximum height and width of the glass package in the window should not be more than 3 meters. Maximum - 3.2 meters.
Accordingly, for greater strength, with non-standard windows, it is necessary to increase the distance between the glasses, the so-called air layer, even sacrificing warmth. The fact is that when using large designs with a small air layer, the deformation of the plastic window may well occur. Due to the climatic drops of glass temperature in a minimum air layer system, it can be interconnected, which will lead to an irreversible deformation of the plastic window. Even in small products, the distance between the glasses plays a big role.
In order to avoid such or similar problems with already installed plastic windows in the apartment, you need to attract specialists to the case. Professionals will be able to more accurately determine which glass packakers are suitable for your dwelling. When calculating, they include all: frosts, wind and many other factors that can affect the plastic window.
Stained-glass insert technologies allow to embody the most bold solutions with the preservation of all energy-saving window properties.
If you want to install an element with colored glasses in your window opening, then it should be remembered that the stained glass is installed solely outside the similar device. So, the window itself must be more durable.
Before ordering and installing a plastic window, it is necessary to organize a natural or artificial blowing with air so that it is not deformed. Without venting, glass can be collapsed due to the thermal expansion of the air inside the structures. It will be more logical to put air conditioning in such a room aimed at double glazed.

When mounting a glass machine with a plastic window, leaving directly to the street, you need to take into account the temperature on the street. At temperatures below than -15 ° C, the installation of plastic windows is undesirable due to the initial deformation of their deformation due to low temperatures. If in the winter it is planned to install a plastic window in the room, it is necessary to reduce the temperature difference - to cool the interior to + 5 - + 10 ° C.
Existing glass classification
The more cameras, the correspondingly there will be more noise and thermal insulation.
Most often, double-glazed windows are classified by the number of aircases that are mounted in them. The main on the Russian market are:
- single-chamber (two glasses and an air chamber between them);
- two-chamber (three glasses and two air chambers between them);
- three-chamber (four glasses and three air chambers);
- Four-chamber (five glasses and four air chambers).
As a rule, when labeling of certain products, most often indicate the thickness, as well as the type of glass, the width of the glass window frame, the amount of aircraft implemented, the type of gas that is used to fill the chambers between the windows.
For glasses, the next label is most often used:
- M is the usual window glass produced using the drawing method.
- F is a window glass that is obtained using a float method.
- K is a glass with a solid coated with low emissions, which is obtained using ON-LINE technology.
- I - glass, which has a low emission coating, which is obtained using OFF-LINE technology.
- S is a glass that is painted in the mass.
- PL - heat transfer film is applied to the glass.
Marking is used for gases that fill aircases. It happens the following species.
If air is used in the air chamber, then the marking is put in the labeling. If it is argon, then write the letters Ar.
The most frequent questions when choosing and buying double-glazed windows
What could be the distance between the glasses?
According to the international standard GOST 24866-99, the distance between the glasses can vary from 8 to 36 mm, and the thickness of the glass package itself ranges from 14 to 60 mm.What are the maximum and minimum sizes of similar products?
The same GOST 24866-99 establishes that the maximum size in the width of the glass pack should not exceed 320 cm, and in height - not more than 300 cm. In addition, the maximum ratio of width and height is 5: 1.

However, from the rules there are exceptions. If experts consider it possible to manufacture a non-standard plastic window with a single-chamber or two-chamber package, then, as a rule, it can be made on production lines of plants.
How can I steal the frames of the plastic window?
There are no restrictions on the use of decorative frames inside the glass. The only condition is to maintain the distance between the frame and glass.Should stroke glass in double-glazed windows be tempered?
Yes, indeed, colored glasses when used in such structures should be hardened. The light absorption coefficient of conventional glasses does not exceed 20-25%. Colored glasses can absorb light in much larger quantities, from 30 to 70%. Therefore, they should be hardened or laminated.
What thickness of glass for the glass package is considered the norm?
It is best to trust in this matter to those specialists. Professional measurers leave to the object, carefully examine the place where it is necessary to install a plastic window, and all sorts of nuances that can play any important role in the operation of the plastic window with a double-glazed window.What is the meaning of the use of sealants when installing a glass package?
If the double-barker is unloaded, it will be visible in subteps condensate.
Sealants ensure the tightness of the interconnect space, which makes it possible to maintain air or gas injected there in immunity. As such a means, polyisobutylene sealants (so-called butyls) are often used in the first layer.
The second layer, which fully seals the package, and not only the interconnect space, and gives the overall strength of the structure, is carried out using polysulfide (thiocol) sealants. Also, polyurethane or silicone sealants can also be applied as the second layer.
The choice of one or another package is not easy. Therefore, starting viewing glazing options, you need to know about all the advantages and disadvantages of a glass package, standards and deviations from them.
