High-quality translucent structures for many years protect the room from the scorching sun, cold and wind, provide optimal humidity in the room, perform protective and other functions. It is important to know how to choose the right plastic windows for an apartment in order to understand which characteristics you need and which ones are not worth paying for.
Window profiles are produced according to EN 12608 SR (Europe) and GOST 30673-99 (Russia). According to the main indicators, they are almost identical. The main parameters are the thickness of the walls of the outer contour and internal partitions. According to these indicators, the profile is divided into three types - "A", "B" and "C".

On the market you can also find windows with a trapezoidal section of the front part of the frame, the so-called "Dutch" or "Danish". Their installation depth exceeds 100 mm and often they do not require the installation of external slopes, completely blocking the opening. Such windows are more efficient than conventional rectangular ones, but they are also more expensive.
Installation depth In addition to their own heat-shielding properties, such frames allow you to install more durable fittings, thick double-glazed windows and additional contours of insulation and sound insulation. But the width of the profile does not necessarily indicate the number of chambers - there are profiles with fewer cavities, but with a width of 8 or even 9 cm. In terms of general thermal insulation properties, they are better than narrow multi-chamber ones - it is not the number of chambers that matters here, but their size and stock air in them. We can conclude that the greater the installation depth, the better the window in terms of thermal insulation and other characteristics.
Choosing windows for a private house When answering the question of how to choose windows for a private house or cottage, one cannot fail to note the importance of having energy-saving qualities. To save on heat carriers in the winter season, it is necessary to give preference to multifunctional double-glazed windows. The chambers of such a window are filled with an inert gas. This means that in winter the double-glazed window will keep heat inside the house, and in summer it will not let the street heat into the room. Such a window will cost more than usual, but the costs will justify themselves in the first season.
The window selection procedure is based on a number of criteria that guarantee the user: reliable protection from external noise (which is important for apartments in a metropolis) energy efficiency; protection from rain, wind and cold; protection against unauthorized intrusions; ease of use; durability (at least 10 years).
The reinforcing element of the window is a U-shaped or square profile, which is inserted into the largest chamber located in the center. The thickness of the sheet metal from which the profile is formed is in the range of 1.5 - 2 mm. It is made of galvanized steel and is highly resistant to corrosion. An amplifier is installed in almost all structures, although according to the standards, with a frame length of less than 0.8 m, it can not be used.
It is certification that is a tool to protect the buyer from an unscrupulous manufacturer, and also acts as a guarantor of safety, confirmation of the declared quality indicators of the goods.
