Remember not to put window foil on an energy glass window that already has a metal layer, as the glass may become too hot and crack.
Newer windows have for 10 years normally have a metal layer to save energy, it also protects very well against microwaves.
Measure inside the middle of the window. hold the meter in the same place and open the window. if the radiation is unchanged, there is no metal layer.
