In this article we will touch upon 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 over 60 years have become very common. At present, 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, and cottage. Why do they so attract a domestic buyer? Let's try to figure it out. Of the positive qualities inherent in them, one can name strength (due to the metal profile), ease of care (they do not need to be painted like wooden ones, and it’s 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, special attention is paid to the types of double-glazed windows. They are divided into one-, two-, and three-chamber - depending on how many air cavities are formed between the glasses.
The norms by which the number of cameras is selected are determined by the climate and temperature conditions of your city. Glass thickness standards are 4 mm, the distance between two glass sheets in a single-chamber double-glazed window is 16 mm, and in a two-chamber double-glazed window - 10.
This is justified by thermal insulation properties. But no matter what types of double-glazed windows you choose, they are all made the same way - sheets of glass connected by frames and sealant, with a space inside filled with gas or dry air. In addition, there are double-glazed windows that are noise-insulating (achieved through the use of glasses of different thicknesses), heat-saving (with special gas argon and with the so-called
low -
emission glass) and
tempered glass (increased strength, because they undergo additional heat treatment), sun-protection (reflect sunlight, protect from radiation).
To this day, such a topic as replacing glass in a double-glazed window remains relevant. Since shock-resistant glass is not often used for the manufacture of windows, it is likely that they may burst. In this case, you can act in different ways: some will want to put a completely new window, others (in order to save) - 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 was glued into a single
tandem; it is a one-piece sealed system with gas and a special substance inside, its goal is to absorb the moisture that forms. All types of double-glazed windows are treated with a composition that protects against fogging and retains heat. Trying to replace only one glass from this complex structure (especially at home), we depressurize the inter-glass space, and the window will no longer be able to function properly.
In conclusion, it should be said that a metal-plastic window - a structure consisting of a number of interconnected elements - is both 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 a manufacturer, you must be careful to consider all these factors in combination. Then your purchase will be of high quality and durable.
