Our Delta window-shielding film protects against radiofrequency (wireless) radiation from mobile phone base stations, NBN transmitters as well as neighbour's WiFi signals.


The Delta window shielding film provides very good to excellent shielding at 1 – 2 GHz.

Shielding effectiveness is shown in the following table in dB. Each 6 dB represents a 50 percent reduction of signal. Therefore, the higher the dB, the greater the attenuation (reduction) of the signal. Attenuation of 25dB or more is desirable for effective shielding.

Will Delta shield protect against 5G?

Our Delta shielding film protects against a wide range of frequencies, as you can see from the table above, including the 3.5 GHz frequency that is being used for 5G.

The degree of protection varies according to frequency. At the 5G frequency of 3.5 GHz, it is between 20 and 32 dB. It has not yet been tested for frequencies above 20 GHz.

  • Removal of films that have been applied with dry adhesive can be difficult and can only be done using razor blade scrapers. However, blades can't be used on Low E glass which has a coating on the inside.  Although film can be applied to this glass, it's not possible to use any blades on the glass for cleaning or removal of film.
  • If you're planning to order new windows or doors in your home, consider this alternative to Low E glass: applying our film to your glass will result in much greater energy efficiency and you won't have to worry about damaging the glass if the film ever needs to be removed.
  • If you choose to install the film yourself, please note that the film warranty will not apply. 

Please note that we take no responsibility for the installation of the film.
