Mu-Copper foil has high damping properties in the electrical field (up to 120dB) as well as in the magnetic field (see table). It is easy to apply, like wallpaper, with a special adhesive for walls, ceilings and floors. This makes it possible to create a Faraday Cage with high shielding performance yourself in an economic way.
Depending on the quality of the doors, vent panels, filters and windows it is possible to realise a damping up to 60-80 dB in the E-field in an existing room without loss of space in just a few days.
The standard width is 1000 mm and the foil can be delivered on rolls or prefabricated sheets. For the joints you can use a 50 mm overlap,seaming tape or copper tape with a conductive self-adhesive
