  The paper describes the Faraday room that shields the CUORE experiment
against electromagnetic fields, from 50 Hz up to high frequency. Practical
contraints led to choose panels made of light shielding materials. The seams
between panels were optimized with simulations to minimize leakage.
Measurements of shielding performance show attenuation of a factor 15 at 50 Hz,
and a factor 1000 above 1 KHz up to about 100 MHz.
