Why We Love It
Our Favorite EMF Protection Fabrics. Great For Curtains and More
In our wireless world, many people are finding they are particularly sensitive to the EMF radiation coming from all manner of wireless energy. If you're wondering about what EMF is, August Brice (our founder) has an excellent well-researched guide to EMF here.
Do Swiss Shield fabrics work to block RF radiation?
Yes! Fabric like both of these semi-transparent, linen-like, metal-infused materials is used by many for protection against high-frequency radiation.
Swiss Shield® Shielding fabrics
This fabric is manufactured by Swiss Shield® in Switzerland with a patented, invisible high-tech yarn- giving it a lovely sheer touch.
We offer two varieties of Swiss Shield fabrics:Ultima Arbour or Naturell -Both are non-conductive and both offer about the same shielding protection.
You can order both the Ultima and the Naturelle fabric by foot and each 12-inch length will be 98 inches in width.
*Please Note: Fabric cannot be returned once cut and shipped. All sales final.
Natural ECO Ultima Arbour :
This is the new ECO fabric made of super soft, super comfy viscose and copper and silver thread. Premium fabric that has the wonderful OEKO-TEX certification that means it's gone through rigorous standards of testing. It's Certified to the OekoTex100 level! That means it's considered safe enough for a baby to wear or touch. No harmful substances and as natural and safe as an EMF protection fabric can be.
EMF Blocking Material So Pure It's Eco-label Certified
We love the light ivory look and the luxurious feel. The Viscose fabric of ECOVERO™, 18 % copper / silver is dry-cleanable so it's a good choice for blankets and curtains. ULTIMA_ARBORis made of of 82 % ECOVERO™ fibers from LENZING™, achieving the exclusive EU Ecolabel certification.
Non-conductive with superb shielding effectiveness of up to 99.9%
ULTIMA_ARBOR™ from Swiss-Shield® is an innovation for those of you that value an ecology and sustainability driven brand focus. Instead of polyester or cotton, this fabric is made from viscose: LENZING™ ECOVERO™ fibers are obtained from certified renewable wood in an ecologically responsible manufacturing process in compliance with high environmental standards and contribute to a sustainable lifestyle and a clean environment. With its very high shielding performance and renowned excellent feel, Swiss-Shield® once again proves that it is a global pioneer in eco-technical fabrics.
OEKO-TEX® STANDARD 100
If a textile article carries the OEKO-TEX® STANDARD 100 label, you can be certain that the fabric content is deemed safe for human health. In many cases the limit values for the STANDARD 100 go beyond national and international requirements. The criteria catalog is updated at least once a year and expanded with new scientific knowledge or statutory requirements. How cool is that! Here's the current cert number; ZH015208475
Technical data
- Width: 250 cm, +/- 2 cm
- Length: Available by the meter
- Attenuation: 42 dB, two-layer 54 dB
- Color: Ecru-White
- Raw materials: 82 % viscose, 17 % copper, 1 % silver
- Weight: 70 g/m²
- Dimension stability: +/- 3 %
Naturelle More Sheer:
Swiss Shield Naturell is a premium, decorative, tight-weave, natural cotton, shielding fabric with MORE EMF blocking ability.

In the photo above, Naturell has the denser weave which, while still sheer, has a more opaque look.
Naturell Features:
- Semi-transparent textile fabric with excellent RF shielding characteristics
- Higher shielding power than Daylite
- Applications include window curtains and liners, canopies, and room dividers and may be used for shielding large surfaces such as complete walls
- Withstands up to 30 washes with no loss of performance
- Washable, easy to iron, cut and sew
- Designed and manufactured in Switzerland
- Incredible 99.99% or 40dB shielding at 1000 MHz and 99%+ effective up to 10Ghz
- No chemical or metallic coatings
- Doesn't flake or wear off after washing
- Contains tiny strands of copper plated with silver, woven in with the fabric to create a barrier
- Soft and pleasant to the touch and attractive to the eye

Both of these materials are a proven, efficient solution against electromagnetic, high frequency (HF), and microwave radiation if used properly.
August, who experiences Electromagnetic Sensitivity, recommends that before attempting to use this on your own, it's best to employ the services of a trained and experienced EMF consultant.
They can help you find hot spots for the different types of EMF throughout your home. The best protection is to distance yourself from wireless devices like laptops, WiFi, and your smartphone. We have many easy ways to help at Tech Wellness.
