ULTIMA Shielding Fabric (roll width 250 cm) is designed to shield high frequency EMF coming through windows and adjacent walls, however this fabric is not intended to shield low frequency electric fields since the conductive fibres are insulated and cannot be grounded.

EMF attenuation: Single layer42 dB (99.993%) at 1 GHz*.  
*For attenuation at other frequencies, please refer to the attenuation chart in one of our pictures.

Features: ULTIMA is a lightweight (70 g/m²) fabric made from 82% cotton, 17% copper, and 1% silver.  ULTIMA has an unbleached cotton colour and the fabric is moderately translucent.  This eco-cotton fabric is made in Switzerland and is certified to Öko-Tex 100 and 1000 standards for chemical safety and sustainable production.  It can be washed at 30 degrees Celsius on gentle cycle, preferably with Texcare detergent, and it can be ironed on low heat (no steam).   This fabric is made with coated copper-silver threads, therefore discolouring from tarnish will not occur.  Due to the 82% cotton content, Ultima fabric can shrink up to 3% after washing.

  • For use as a translucent daytime drape to shield high frequency EMF coming through windows and walls.  Can be used at night with an additional EMF shielding curtain for extra attenuation during sleep times.
  • Can be used for making your own canopies to shield beds from high frequency EMF during sleep time.  Canopies made from SILVER-TULLE can also be purchased on this website.
  • For indoor use only.

    This fabric can be purchased by the roll-metre (roll width is 250 cm).  Please enter quantity of metres required (minimum quantity is one roll-metre).
