NATURELL Swiss Shield® fabric -50 dB at €115 incl. VAT (per linear metre)

 Swiss Shield Natural Fabric -50dB max is a biocompatible, high-performance UMTS/3G/4G anti-wave and anti-EMF veil that blocks 99.98% of high frequencies from 0.5 to 20 GHz. Hypoallergenic, washable (metal protection with polyester sheath).

Attenuation -41dB at 1 GHz

Sold by the linear metre: 1 linear metre x 2.5 metres wide = 2.5 m²

 Used by the military and industry in various countries, it is also used for curtain-type screen fabrics, anti-high frequency canopy/canopy "Faraday cages" during sleep (SLEEPING HFshield), as well as for the manufacture of high frequency protective clothing.

 Features:

• Biocompatible. It contains very little metal, thus avoiding any possible poisoning from excessive metal content when the metal oxidises through respiration once the body is inside the Faraday cage. (Metal protected by polyurethane sheath).
• Extremely hypoallergenic
• Antiseptic
• Highly breathable
• Highly luminous
• Resistant and tear-resistant
• Easy to handle and use
• Antistatic
• Designed for people with chemical sensitivities (hypoallergenic)
• Materials: cotton / 1% silver / 17% copper / polyester
• Width: 2.5 m
• Thickness: 0.1 mm
• Colour: white
• Approximate weight: 70 g/m²

Attenuation efficiency:

• Electrostatic fields: 99.9999% attenuation
• Electric fields, low frequencies: 99%
• High frequencies: according to the certificate below:

Meets military testing standards MIL-STD 285 or IEEE 299-1997

Emissions concerned:

• GSM/DCS/GPRS/UMTS cellular telephone network
• DECT cordless telephone
• WLAN: private wireless communication networks
• Wi-Fi
• Bluetooth
• Microwave (microwave oven leaks)
• Satellite transmission
• Radar

Possible applications:

• Curtains made from this fabric significantly reduce the penetration of high frequencies from mobile phones (relay antennas) while allowing daylight to enter.
• Faraday cages can be made to create a closed enclosure, which is the most effective solution for attenuating high frequencies. See the SLEEPING HFShield tab.
• Linings for clothing that protect against high frequencies. The Swiss army uses this protective fabric for its soldiers, as well as for technicians responsible for measuring high-frequency emissions near transmitting antennas.

Swiss Shield -50dB Natural Fabric is a biocompatible anti-wave and anti-EMF veil that is certainly the most effective at blocking 99.9999% of high frequencies from 0.5 to 20 GHz. Hypoallergenic, washable (metal protection by polyurethane sheath).

A 0.02-millimetre copper wire is coated with a silver wire. To prevent any metal emissions into the atmosphere or potential oxidation, this metal wire is completely coated with polyurethane lacquer. The wire is then 0.024 millimetres thick. This manufacturing process is unique in the world and is covered by a global patent.
