STEEL GRAY shielding fabric | for curtains, bedding and blankets | RF radiation shielding with 99.99% efficiency (up to 41 dB) | Groundable LF. Effective against 5G!


STEEL GRAY shielding fabric is made out of cotton wool, polyester, and stainless steel threads. Good screening attenuation against electrosmog caused by low-frequency electric alternating fields (groundable) and high-frequency mobile radiation. Screening attenuation of up to 41 dB, even at frequencies above 5 GHz.

Ideal use as a cheap, opaque curtain and textile product, such as bedding or ceilings.

Effective shielding attenuation of 5G frequencies. Two layers at 40 GHz up to high 67 dB shielding effectiveness!

Shielding fabrics are also able to be sewn on to clothing to protect from electrosmog

STEEL GRAY shielding fabric against electrosmog. RF radiation shielding up to 41 dB, groundable. Ideal for opaque curtains and textile products such as bedding and ceilings. Groundable LF. Effective against 5G!

This shielding fabric was processed for our sleeping bag, linen and blanket for effective protection against LF and HF electrosmog. The fabric contains stainless steel threads and is therefore contactable, which means that LF electric alternating fields can be earthed. The HF mobile radiation screening attenuation is a high 41 dB and applies to high GHz frequencies.

STEEL GRAY is ideal for curtains and for products around the bed and couch because of its properties. However, it is less suited to clothing because stainless steel threads are not soft and comfortable on the skin as silver threads. At best, the feeling can be compared to an itchy wooly sweated. STEEL GRAY is very robust compared to silver fabrics and is therefore extremely durable. It can also be washed and ironed.

Use and assets of the STEEL GRAY

STEEL GRAY is an opaque fabric made of cotton wool, polyester and stainless steel used for HF+LF protection. It is typically used for curtains, flooring underlays, ceilings, furniture (beds), screens, beddings and, although not often, as a cheap clothing fabric.

  • Good screening attenuation, even at high frequencies!
  • Excellent price/performance ratio
  • Contactable (groundable) to protect from LF fields
  • Textile properties: Washable, can be ironed, can be sewn
  • Quality grading: Very high

Caring for the STEEL GRAY shielding fabric

Wash gently at 30°C | Do not tumble dry | Do not bleach | Do not dry clean | For allergy sufferers: every new fabric smells, wash before first use! We recommend TEXCARE or our ecological, vegan UNI SAPON detergent.

No cancellation for FABRICS

Like for cuts, there is no right to return shielding fabric.

Please note that cancellations do not apply to these products, because they were cut to the customer’s specifications. Reselling a tailored item is no longer possible. For this reason, it is possible to request a free sample of the STEEL GRAY shielding fabric. By ordering pre-finished products, waiving the statutory right to return goods is accepted. We only sell the highest-quality fabrics! Because of the high production costs and a favourable price, small flaws are not grounds for complaint.

    Wir haben mit dem Stoff auch einen Strahlenschutz für unsere Katzen gemacht. Das Traurige war nur dass sie sofort hinein gingen und nicht mehr heraus komen wolten.
