Conductive Shielding, Cotton Comfort
Copper-nickel Faraday fabric in two practical sizes.1
Copper-nickel layer
under a soft cotton face
1 A peer-reviewed experiment measured 53 dB at 1.5 GHz on a copper/nickel-coated polyester textile specimen. At a tested frequency, 20 dB and 40 dB mean 99% and 99.99% less RF power transmitted through the tested material. RADIHALT uses a copper/nickel conductive inner layer; real-world results depend on coverage and setup. Cu/Ni textile experiment (Polymers, 2021).

How it works
What makes a soft blanket shield?
Inside the cotton is a woven copper-nickel textile. Conductive metal reflects and absorbs radio-frequency energy, so less of it passes through the area the blanket covers. It needs no power, no app and no setup.
- 1
Unfold
It packs flat into a bag or drawer, so it is ready wherever you sit down.
- 2
Place it between
Lay it across your lap, under a tablet or beside you — between the device and your body.
- 3
Use your devices
Keep working, scrolling and streaming. Keep laptop vents clear and a hard surface underneath.

Laptop Radiation Exposure: What It Is and How to Reduce It
Laptop radiation exposure comes from several sources: Wi-Fi, Bluetooth, power supplies, screens, and electric or magnetic fields near the device. This guide explains what the evidence says, why regulators disagree, and the practical steps that reduce exposure without fear or guesswork.

Use, care, materials and fit. Something else? Ask us.
All questionsRADIHALT's copper/nickel conductive inner textile attenuates RF energy along the path it covers. Place it between a wireless device and the area you want to shield; open sides and placement affect the result.
Shielding can affect a device's connection if it covers the antenna. Keep laptop and router vents clear, and check the connection in your own setup.
Silver can shield RF too. We chose copper/nickel for a conductive inner textile with published material research and a practical balance of conductivity, corrosion resistance, and material cost. Our blanket pairs that layer with a soft cotton exterior.
RADIHALT uses a 100% cotton outer layer and an inner Faraday textile composed of 60% polyester, 32% copper, and 8% nickel.
Choose 18 × 18 inches for a compact lap or desk setup, or 36 × 30 inches when you want wider coverage. Both formats use the same copper/nickel construction.
Yes. Hand wash below 40°C with mild or neutral detergent, then hang dry with the cotton side out. Do not machine wash or tumble dry; cool iron only the cotton side.
Many people choose to limit avoidable RF exposure as a precaution. RADIHALT provides a physical shielding layer between a wireless device and the area you want to cover. The reduction depends on coverage, frequency, and placement.
