The insulation of any apartment begins with window openings, because most of the heat leaves precisely through balcony and window openings. To date, there are two ways to glazing balconies of the loggias — warm and cold glazing. With cold glazing, the loggia or balcony is simply protected from street dust, noise and atmospheric rainfall. This method of balcony glazing allows you to raise the temperature in the room by only 3 degrees, and this is the ultimate maximum, that is, this method of insulation is ineffective. On the other hand, this method of glazing is quite simple in execution and does not take much time.
