Organic cotton, 40 db

NATURELL is a soft, breathable, semi-transparent cotton fabric for the protection against high-frequency (HF) radiation. Perfectly suited as curtain. 100% textile characteristics: Washable, easy sewing and ironing. For questions  please contact us by email.

 Attenuation 40 dB (99.99 % shielding effectiveness) at 1 GHz. Attenuation certified by Prof. Dipl.-Ing. P. Pauli of the University of the German Federal Armed Forces in Munich, Germany. The shielding power is effected by a wrapped silver-plated copper fiber. 

      • Material: Ecological/organic cotton fabric, certified to Öko-Tex 100 and 1000.
      • Colour: white, unbleached. 
      • Cannot be grounded.
      • Width: 2.50 m,
      • Length: linear meter.

Note:  The cotton fabric will shrink about 10 % in the first wash.  It needs to be washed as Delicates so it can drip dry, as it tends to be quite crinkled, after washing.  Even ironing will not quite get rid of all the crinkles. 

You can order this product in measures of 0.1 linear meters. Please enter for instance 4.6m in your order. This product is cut off a large roll of fabric according to customer specifications. No returns possible, sorry.

Screening attenuation: All stated attenuation values apply at 1 Ghz. Measurement to ASTM D4935-10 or IEEE Std 299-2006 or IEEEE Std 1128-1998 or ASTM A698/A698M-07. You find the test report above under "Report screening attenuation".

Grounding: Not electrically conductive. No shielding of electric fields (LF), these must be reduced by additional procedures. We recommend the shielding with NSF34, NCV95 or the decoupling with a demand switch.

Fabric care: Washing at gentle cycle 30°C | Ironing without steam at degree 1 | No drying in tumble dryers | No bleaching | No chemical dry-cleaning | For allergy sufferers: Every new fabric smells, wash before its first usage!
