Our technical fabrics (wall cloth, technical wallpaper, etc.) are electrically conductive. They have excellent properties against electromagnetic waves in high (HF) and low frequencies (BF). The EMC protection is provided to block the radiation of the telephone: mobile, 5G, wireless DECT, Wifi, Wimax, Bluetooth, radars and all other radiation, except those of the plane waves. The anti-surface fabric must be grounded by a professional electrician with a proper grounding kit to be effective. It is advisable to overlap the layers of canvases on 2-3 cm to ensure a good continuity of electromagnetic shielding. It is also recommended to cover this conductive fabric with an electrically insulating coating to prevent it from being damaged over the years. Their applications are for faradisées data centers, research laboratories or TEMPEST rooms.
