How to distinguish energy-saving double-glazed windows from regular ones?

In 2024 the installation of energy-saving double-glazed windows is a standard solution in the cold regions of our country. These double-glazed windows differ from ordinary ones by a special coating that reflects part of the infrared (thermal) radiation back into the apartment. Thereby they reduce your spending on heating. 

But if you ordered the installation of such a window, how do you check that you were not deceived and not given ordinary glass without the special coating? After all, outwardly they do not differ in any way! 

It is all very simple – bring a lit lighter or candle up to your window and look carefully at the reflections that appear on the glass. If an energy-saving coating has been applied to the glass, then one of the flame’s reflections will have a bright red color. If "multifunctional glass" has been installed, then two reflections will change color.
