RadioFilm is great for shielding radiofrequency when both transparency and shielding performance are required. Use it on windows, TV/computer screens, digital displays, visors and more. 50-60 dB attenuation and highly conductive on one side (0.12 Ohm/sq). The grid is a diamond pattern which minimizes the Moire´ effect in most applications. Amazing 61% light transmission too! Very easy to connect to ground on the conductive side. There is no adhesive on this material. 12 inch wide.
