Prefabricated Faraday cages

Our prefabricated self-standing modular Faraday cages offer superior screening of RF/LF/HF signals, e.g. for R&D, TEMPEST and Testing purposes

Mu-copper wall covering system

Mu-Copper foil has high attenuation properties in the electrical field (up to 120 dB) as well as in the magnetic field.

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 0.12mm thick Mu-Copper is used to transform a regular room into a shielded room; the product 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 1000mm. The foil can be delivered on rolls or as ready-made sheets.

Overlap options

For the joints you can use a 50mm overlap. For extra high performance you can fully solder the joints or use a seaming /copper tape with a conductive self-adhesive to apply over the joints.



For ventilation we have developed honeycomb ventilation panels. Especially for the Mu-copper Faraday cages we
can deliver honeycomb vent panels with a Mu-copper
flap around the edges. It is easy to solder these into
the Mu-copper Faraday cage

Shielding performance



In addition to EM shielded doors and windows, the screened rooms can be equipped with the following components:

We also offer shielding solutions for water pipes, medical gases, and ventilation when needed.


The Mu-copper Faraday cage can be equipped with the following options:

  • Wave guides for data communication
  • Shielded windows
  • Shielded ventilation panels
  • Power line filters
  • Signal line filters
  • Shielding solutions for water pipes and (medical) gases
  • Standard interior finish is possible (like glued plasterboard, foam tiles or plywood)

You can create a Faraday cage with high shielding performance yourself in an economic way, using local labour. This is possible in existing buildings as well as in new ones, without loss of space. Depending on the quality of the doors, vent panels, filters and/or windows used, attenuation levels up to 80-100 dB in the E-field can be realized. When more layers are applied, it is possible to achieve over 120 dB.


The system can be used with a detachable or fixed ceiling to separate existing ducts and cables from the shielded room.



Modified RF shielded door

When a lower performance of e.g. 40-60 dB is acceptable, we can retrofit your existing door. The door is then equipped with gaskets at the top and sides, and with a conductive copper brush and doorstep at the bottom.

Both swinging and sliding doors are suitable for being shielded this way.

For heavy duty applications we can supply Faraday cage doors that offer up to 140 dB reduction.
