Shielded Rooms by Holland Shielding

Faraday cage and shielded room engineering, installation and verification
EMI/RFI, EMP and EMSEC protection for rooms, equipment and critical environments

Faraday cages and shielded rooms reduce electromagnetic interference and unwanted signals entering or leaving a controlled environment. They are used for EMC testing, secure communication, research, defence, critical infrastructure and other applications where reliable electromagnetic shielding is required.

When is a Faraday cage or shielded room required?

A shielded environment can be used when sensitive equipment, confidential information, reliable measurements or critical systems require protection against electromagnetic interference.

Protect sensitive equipment

Reduce external electromagnetic interference that could affect electronics, measurements and communication systems.

Control unwanted emissions

Help reduce electromagnetic emissions leaving the shielded room and affecting nearby equipment or environments.

Create a controlled environment

Create a stable electromagnetic environment for testing, research, secure communication and technical work.

Typical shielded room project process

Design, production, installation and verification are coordinated as one complete shielding project.

1. Define

Review the application, dimensions, frequency range, required attenuation and installation environment.

2. Engineer

Design the room, access points, filters, ventilation and conductive connections.

3. Produce and install

Manufacture, prepare and install the shielding components according to the agreed design.

4. Verify

Measure the completed room using the agreed test method, frequency range and acceptance criteria.


Choose the right shielded room construction

The suitable construction depends on the available space, installation method, frequency range, required attenuation and future modification requirements.

A single weak point can affect the complete room

An untreated opening, unfiltered cable, poorly connected seam or incorrectly integrated door can create an electromagnetic leakage path. We therefore assess the complete shielded environment rather than only the wall or panel material.


Typical Faraday cage applications

Faraday cages and shielded rooms are used across industries where electromagnetic interference, information security or reliable testing must be controlled.

Defence and aerospace

Tempest shielded environments for military systems, aerospace electronics, secure communications and EMP-related applications.

Government and security

Tempest secure rooms for government buildings, communication systems, intelligence environments and public safety applications.

Datacenters and infrastructure

Tempest shielding for datacenters, telecom systems, utilities, energy installations and other critical infrastructure.

Research and laboratories

Controlled environments for universities, EMC laboratories, research institutes and sensitive scientific measurements.

Industrial and manufacturing

Shielded spaces for industrial automation, machinery, control cabinets, production equipment and EMC testing.

Medical and healthcare

Shielded environments for MRI systems, hospitals, laboratories, medical devices and interference-sensitive equipment.


Shielding performance verification

The shielding performance of a completed Faraday cage or shielded room can be verified by measurement. The frequency range, test positions, measurement method and acceptance criteria should be agreed before testing. A measurement report or shielding effectiveness certificate can be provided when required.

This can be relevant for:

  • EMC test environments
  • Pre-compliance testing
  • TEMPEST-related rooms
  • Secure communication environments
  • Laboratories and R&D facilities
  • Data centers and critical infrastructure
  • Military, aerospace or defense-related applications
  • EMP/HEMP/NEMP-related protection
  • Environments with sensitive measurements or electronics

Frequently asked questions
What shielding performance can a Faraday cage achieve?

The achievable shielding performance depends on the construction, materials, frequency range, doors, filters, ventilation, cable entries and conductive connections. The required performance should be defined before the room is designed.


Can an existing room be converted into a shielded room?

Existing rooms can often be converted. The floor, walls, ceiling, doors, windows, ventilation and technical penetrations must first be reviewed.


Can ventilation and cooling be added?

Shielded ventilation panels, air-conditioning penetrations and cooling systems can be integrated without creating unnecessary electromagnetic leakage paths.


Can power, data and signal cables enter the room?

Power, data and signal connections can be integrated using suitable filters, waveguides, feedthroughs and shielded cable-entry systems.


Can the completed room be measured?

The completed room can be measured using an agreed frequency range, test method and acceptance criteria. A measurement report can be provided when required.
