Faraday Fabric is a type of textile that protects against damaging electromagnetic fields (EMFs), enhances privacy, and prevents information theft. Faraday Fabric, which is often composed of copper, nickel, silver, or a combination of the three, prevents EMF and RF waves from penetrating.
It achieves this inhibition by having a hole in the fabric more minor than the wavelength of the signals blocked, causing radio waves or EMF to reflect off the material.
