How to choose metal-plastic (PVC) windows, so as not to doubt their quality? Which, according to experts, plastic windows are better to put in a country cottage, and which ones - in an apartment in a city skyscraper?

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.

Choosing a PVC window seal Tightness is one of the mainof plastic windows. It is achieved by using special sealing elements that are laid around the perimeter of the doors and prevent the penetration of moisture and cold from the street and the escape of heat from the side of the house. In addition to these functions, the seal is also a good sound insulator, not inferior in terms of sound reduction to the best double-glazed windows.

We recommend choosing plastic (PVC) windows in which the air chambers between the panes are filled with argon or krypton. This design will significantly save the cost of heating in winter and air conditioning in summer.

It is because of the poor quality of fittings that buyers of PVC windows face the following problems: jamming of the sash; opening the window only with effort; blowing due to the inability to tightly close the sash; creak.

All profiles in exprof windows are equipped with reinforcing inserts with a thickness of 1.5 to 2 mm and have a protective zinc coating. Double-glazed window The main characteristics of the element: the thickness of the double-glazed window, the number of glasses and, accordingly, the chambers between the glasses, the presence of special glasses with heat-shielding coating.

Window profile width The wider the profile section (the distance between outdoor and indoor surfaces), the warmer and quieter the translucent structure will be. In a wider profile, you can put a double-glazed window with better thermal insulation and noise reduction characteristics.

Profile A. External wall thickness from 2.8 mm, internal - from 2.5 mm. The best profile for residential buildings. Profile B. External walls from 2.5 and internal from 2.0 mm. Suitable for installation in heated and unheated rooms. Less resistant to mechanical stress.

To reinforce the plastic profile, special steel inserts are used, which are mounted directly into the main chamber of the PVC profile. The thickness of steel reinforcement in translucent PVC structures according to GOST should not be less than 1.5 mm.
