Wifi signals can go through walls, but most go through windows. Architectural trends show that more and bigger windows are being put in offices all the time. Along with that, the use of wireless signals has also increased and will continue to do so. These things combined increase security risks. Reflective window film reduces leakage.
To increase its effectiveness a metal strip can be placed around the gap between the film and the window frame. No window film application can be done with no gap between the film and the frame though the gap is small. 1/8 inch is an acceptable application.
