GEOVITAL Baumwolle NOVA is a semi-transparent curtain fabric for shielding high-frequency electromagnetic radiation (HF). Typical applications include curtains and drapery. Due to its high light permeability, it is ideal for windows and bed canopies.

Care instructions
Very gentle washing in the wool wash cycle (hand wash program) or delicate cycle at 30 degrees. Please use only mild, ecological, phosphate-free detergents. Do not use BLEACH! Iron without steam on level 1. NOVA shielding fabric should be hung to dry quickly.

  • Do not tumble dry
  • Do not wring or twist
  • Do not dry clean.

Grounding of NOVA Cotton not possible

Cannot be contacted and therefore grounded. Low-frequency electric alternating fields (NF) must be reduced by additional measures. We recommend shielding with T98 shielding paint or enabling with a GEOVITAL network switch.

Shielding attenuation of NOVA

The shielding attenuation was measured according to the standards ASTM D-4935-2010 and IEEE 299-2006 by the University of the Bundeswehr Munich and confirmed in a report.

INFO: We deliberately do not use earthable shielding fabrics. Earthable shielding fabrics are not coated!
- i.e. the silver threads in the fabric are not protected, and the shielding is usually worn off after the third wash due to the mechanical friction in the washing machine. This means that an expensive shielding fabric has been purchased that is worth nothing in a short time...
- Earthable fabrics are usually gray to dark gray, not very light-permeable, and air-permeable! Actually unsuitable for small canopies.
- Since the fabric is not coated, these fabrics discolour extremely due to light and UV radiation, become blotchy, and later look unsightly.

Quantity of fabric for window: For a curtain at the window (2 m width), 4 running metres of NOVA screening fabric are required for a divided curtain. In order to ensure the usual corrugation (gathering) of a curtain, at least a factor of 1.5 must be calculated.
