Architectural Shielding

The evaluationĀ of shielding attenuation requirements, frequency rangeĀ and cost will dictate the most effective material and method of installation used.


As technology evolves, the increasing use of electrical equipment becomes ever more complex. The interference issues caused by the emitted electromagnetic fields (EMF) result in the need for Architectural Shielding to protect buildings and electronic equipment housed within.

Architectural shielding protects the building from electromagnetic fields using a range of suitable materials bonded directly to the host building. Commonly used materials include heavy duty (0.125 mm thick) copper and aluminium foils and steel sheet.

The evaluation of shielding attenuation requirements, frequency range and cost will dictate the most effective material and method of installation used. The careful design, installation and selection of apertures will ensure the maximum practical performance will be achieved from the materials selected.

Waveguide vents are also a crucial component for any shielded building, room or enclosure as they allow air to pass through whilst still attenuating radiated interference. As such, EEP design and manufacture a wide range of steel and aluminium waveguide vents specifically for all shielding applications.

Where possible, all projects should have a defined specification stating the required shielding attenuation over a specified frequency range. Most projects have not got this information initially available, therefore EEP can carry out initial site surveys to quantify background field strengths, and from that the level of attenuation that is most appropriate.

In addition to the initial site survey, European EMC Products offer a complete service from the design, supply and installation, to the final attenuation testing which is recommended upon completion of the works to show conformance to the original specification.
