    • Ecological cotton fabric without chemicals, certified to Öko-Tex 100 and 1000
    • High screening attenuation for a cotton fabric
    • Excellent cost/performance ratio
    • Textile characteristics: Washable, easy to iron and process
    • Quality grade: Very high

    Technical data:

    • Width: 250cm  ±2cm
    • Length: Available by the meter
    • Attenuation: 40 dB
    • Color: Ecru-White

    • Weight: 70 g/m²
    • Dimension stability: +/- 3 %
    • Certificates: Öko-Tex 100 and 1000

    Grounding:
    Cannot be contacted and therefore cannot be grounded. Low-frequency electrical fields (LF) must be reduced by additional procedures. We recommend to shield these fields or to switch them off with a demand switch.


    Shielding attenuation:
    All shielding attenuation values are valid at 1GHz. Measurement according to ASTM D4935-10  /IEEE Std 299-2006 / IEEEE Std 1128-1998 / ASTM A698/A698M-07.

    RF Shielding Fabric "Swiss Shield Naturell"
     

    • for shielding widely against RF high frequency electromagnetic waves
    • decorative half  transparent cotton fabric with spon- in silvered copper filaments
    • 100% textile character: washable, easy to manufacture and to iron
    • ideal curtain material with typical textile characteristics of cotton

    This material is preferably used as curtain material in front of windows, for partial shielding of walls or as bed canopy. It is soft, light, transparent and ist easy to sew, respectively to manufacture. Swiss Shield Naturell shields particularly well high frequency electromagnetic waves (by reflection). The shielding attenuation is independent from the direction of th incoming signals.
    In order to avoid slits in the RF shield, oberlapping seams should be made on sewing.

    Swiss Shield Naturell needs not and cannot be grounded.

    Please note:
    RF shielding measures without groundings presume that the electrical AC fields existing in the concerned room are reduced to a minimum by switching off voltage or by shieldings. If this is not done before, the non- grounded RF shielding areas, even those which cannot be grounded can couple to electrical AC fields and can intensify their effects.
