In this article we will touch on such a popular topic today as double-glazed windows for plastic windows. If you delve into the history of their occurrence, you can find that they appeared in the middle of the last century. And for more than 60 years have become very common. Currently, metal-plastic windows are still considered the most fashionable of all varieties.
According to statistics, more than 70% of people in our country have these windows in their apartment, house, or dacha. Why do they attract domestic buyers so much? Let's try to figure this out. Of the positive qualities inherent in them, one can name strength (due to the metal profile), ease of maintenance (they do not need to be painted like wood, and it is much easier to wash them), good insulation from external noise, heat preservation in the room, and, finally, aesthetics, which for many is not in last place.
One of the main elements of a metal-plastic window is a double-glazed window. Therefore, the types of double-glazed windows deserve special attention. They are divided into one-, two-, three-chamber - depending on how many air cavities are formed between the glasses.
Norms,according to which the number of cameras is selected, are determined by the climate and temperature regimes of your city. Glass thickness standards - 4 mm, the distance between two glass sheets in a single-chamber double-glazed window - 16 mm, and in a double-glazed window - 10.
This is justified by thermal insulation properties. But whatever types of double-glazed windows you choose, they are all made in the same way - sheets of glass connected by frames and sealant, with the space inside filled with gas or dry air. In addition, there are noise-insulating double-glazed windows (achieved through the use of glasses of different thicknesses), heat-saving (with special argon gas and with the so-called low-emission glass) and tempered glass (increased strength, as they undergo additional heat treatment), sun protection (reflect sunlight, protect from radiation).
Replacement of glass in double-glazed windows still remains relevant. Since impact-resistant glass is not often used to make windows, there is a possibility that they can burst. In this case, you can act in different ways: some will want to install a completely new window, others (in order to save money) - only damaged glass. Nevertheless, experts call the best way out of this situation to replace only the double-glazed window with which the incident occurred.
The reasons for this are simple: a double-glazed window, as already mentioned, is not ordinary glass that has been glued together in a single tandem; it is completely sealeda system with a gas and a special substance inside, its purpose is to absorb the resulting moisture. All types of double-glazed windows are treated with a composition that protects against fogging and retains heat. Trying to replace only one glass of this complex structure (especially at home), we will depressurize the space between the panes, and the window will no longer be able to function properly.
In conclusion, it should be said that a metal-plastic window is a structure consisting of a number of interconnected elements - this is a profile, and types of double-glazed windows of various configurations, and accessories, and fittings, without which it is impossible to ensure the correct operation of the entire system. And when ordering a window from any manufacturer, you need to be careful, take into account all these factors in combination. Then your purchase will be of high quality and durable.
