The pictures show an older two-glazed window in comparison to a ConverLight Static Facade from the inside. The image is taken with a thermal camera, at an outdoor temperature of -11 °.
The surface of ConverLight Static Facade (right) is basically room temperature on the inside, so basically no drafts at all. For the older two-glazed window (left), the situation is different. As a result of heat leakage the temperature drops to 11 °, which will cause significant drafts that must be heated with a radiator.
