EMF Window Film Hi Lite LX70 – 91cm (36″) wide

The EMF Window Film Hi Lite LX70 is the best we know of. It is almost indiscernible to the eye but has fantastic screening capabilities.

It effectively screens phone masts, GSM, 2G, 3G, 4G, WiFi, smart meters, cordless phones and baby monitors, and it even looks well set to mitigate 5G. Yes, it is expensive, but if applied by a professional installer, it comes with a ten-year warranty.

Recent testing against the millimetre wave has confirmed that with:

• a single layer of LX70 + a single layer of BlocFilm Bronze (SB35), the attenuation is 40.2 dB at 40GHz.
• a double layer of LX70 + a double layer of BlocFilm Bronze (SB35), the attenuation shoots up to a pleasing 65.9 dB at 40GHz.
