Mu-Copper Faraday Cages


STR Mu-Copper foil has high attenuation properties in the electrical field (up to 120 dB) as well as in the magnetic field (see shielding performance table). It is easy to apply, like wallpaper, thanks to its special adhesive for walls, ceilings and floors. The interior finish can be plaster board, foam tiles or plywood.

The 0.12 mm thick Mu-Copper is used to transform regular rooms into shielded rooms; it has excellent shielding performance even at low frequencies. The system is easy to mount on shielded doors with clamping devices. The standard width of Mu-Copper is 1000 mm and the foil can be delivered on rolls or ready-made sheets.
