Mu-copper Faraday cages
Mu-copper foil is used to create a Faraday cage in an existing room or building
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 0.12 mm 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 1000 mm. The foil can be delivered on rolls or as ready-made sheets.
For the joints you can use a 50 mm 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.

In addition to EMI 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:
- Waveguides 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.
How to order
You can indicate below how many square meters Mu-copper foil you need to cover your room. You can also specify if you want an offer for adhesives for pasting the Mu-copper on the walls and solder for closing the seams.
