copy of Swiss Shield Natural Curtain

Swiss Shield -50dB Natural Curtains offer 99.9999% protection against electromagnetic waves and high-frequency signals from relay antennas, Wimax and Wi-Fi, covering high frequencies from 0.5 to 20 GHz. Hypoallergenic, washable (metal protection with polyurethane sheath).

Available with Ruflette, loops or eyelets.

They protect against waves outside the home that can enter through windows.

The curtain is available with a ruflette or 4 cm diameter matt nickel eyelets, or optionally with loops (less recommended for wave attenuation) and only on quotation.

Choice of dimensions:

The curtain must be 60 cm wider than the width of the window X in order to ensure good coverage all around the window, i.e. X + 60 cm. This width must be multiplied by 1.3 so that the curtain has a minimum amount of gathering.

Curtain width to choose = (window width + 60 cm) x 1.3

Fabric description:

A 0.02 mm copper metal wire is covered with a silver wire. To prevent any metal emissions into the atmosphere or potential oxidation, this metal wire is completely covered with a 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.

This fabric is 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, and for the manufacture of high-frequency protective clothing.

 Characteristics:

• 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/silver/copper/polyurethane
• Width: 2.5 m
• Thickness: 0.1 mm
• Colour: white
• Approximate weight: 69 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.

We can make custom-made curtains and/or curtains with multiple layers. Please contact us for this request.
