NATURELL fabric EMF shielding | Width 250 cm | Metres


Swiss-Shield® NATURELL fabric EMF shielding. Semi-transparent cotton EMF shielding fabric as curtain or for canopies. Ecru-white. 40 dB. Width 250 cm.


Swiss-Shield® NATURELL fabric EMF shielding is a semi-transparent ecological cotton fabric. For the shielding of high-frequency electromagnetic fields (HF). Typical application as a curtain. Not electrically conductive.

  • Ecological cotton fabric without chemicals
  • High screening attenuation for a cotton fabric
  • Excellent cost/performance ratio
  • Textile characteristics: Washable, easy to iron and process
  • Quality grade: Very high

Attenuation | Grounding

  • Shielding high frequency electromagnetic fields (HF). The indicated dB-values apply to 1 GHz, view chart for other frequencies. Laboratory report ranging from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006, view report above.
  • Without an electrically conductive surface does not shield low frequency alternating electric fields (LF).

Attenuation | EMF Shielding dB / %

10 dB = 90 % 
20 dB = 99 %  
30 dB = 99.9 % 
40 dB = 99.99 % 
50 dB = 99.999 %
