Agree, it is better to spend money on a high-quality window once than to endure the inconvenience later due to the fact that it is cold in the apartment or extraneous sounds penetrate from the street.
Table
What is the difference between a double glazing unit, see the table below. It remains only to announce a simple technique with which you can determine the number of cameras in a double-glazed window by eye. We bring a lighted match to the glass: if three lights are reflected, then there are three glasses, and the double-glazed window, respectively, is two-chamber. If there are two lights, then there are also two glasses, and the glass unit is single-chamber.
Single glazing | Double glazing | |
Number of glasses | Two | Three |
Insulation and sound insulation qualities | Average, but higher than old wooden windows | High |
The cost per square meter of a glass unit (average, since there is a large gradation due to the type of glass and the width of the profile) | 1250-1400 rubles | 1600-1800 rubles |
