Unfortunately, even if this works for the area of the glass, it does nothing to affect signal going through the wall next to the window.
Without shielding the entire structure - including roof and floor - its really not possible to stop signal leakage.
Wireless companies like Aruba invest significant sums of money in RF cages from test equipment manufacturers. These are enclosed areas that provide significant reduction of signal. But even they are not perfect. Typical signal reduction is 30-40dB for the rooms we purchase at a medium price point.
