The demand for the improvement of access modes to shielded locales has evidenced how the doorway assumes a relevant significance and has contributed to the creation of types responding to different attenuation, of frequency requirements and values, both for magnetic and electromagnetic fields and plane waves.
We can provide lightweight doors in aluminium, steel and iron, as a function of the shielding values. Beginning from this differentiation we can guarantee the following attenuation values:
These doors are distinguished by the following points:
- type of opening;
- type of gaskets and fingers installed;
- by construction;
- by installation, if they need to be installed on walls in masonry or in metallic panels and shelter structures. These doors have been installed and qualified with electromagnetic tests. The most current doors with shielding values of 60 – 70 dB may even have very simple floor ingresses.
