BlocCopper EMF Shielding Fabric 44″ Wide

BlocCopper Copper EMF Shielding Fabric: 70 dB From 100 MHz to 3 GHz

BlocCopper is a solid weave anti-radiation fabric made of nickel, copper and polyester, in a copper color. It reduces and blocks the radio frequency emissions from cell towers, smart meters, WiFi routers, next-generation technology and all wireless devices, with 70 dB of shielding from 100 MHz to 3 GHz. It is one of the strongest shielding fabrics we sell, with the trade-off of not being breathable. Browse our full range of EMF shielding fabrics to compare options.

Solid Weave, Robust and Hard Wearing

BlocCopper is a solid weave fabric, which gives it very high shielding but means it is not breathable. That makes it best for places where breathability does not matter: under floors, under beds and behind curtains. It is very robust and hard wearing.

Does Copper Block Radiation?

Copper is a highly conductive metal, which is why it is widely used to shield against radio frequency signals. In BlocCopper, copper and nickel are combined with polyester to make a flexible fabric you can cut to size. Its published shielding is 70 dB from 100 MHz to 3 GHz. Decibels are a logarithmic scale: every 10 dB is a tenfold reduction in signal power, so 70 dB is a very large reduction in the signal passing through the fabric.

Underfloor, Under Bed and Curtain Lining

• Underfloor protection: use it under carpets to shield from signals coming from below.
• Under bed protection: use it as a bed mat in tandem with a canopy to create a Faraday cage around the bed.
• Curtain lining: line curtains to shield windows.

Because it is highly conductive, BlocCopper is also well suited to grounding, and to discharging the low electric fields from house wiring and electrical appliances.

Also Blocks RFID Scanning

BlocCopper also blocks RFID scanning, so it can be used to line wallets and pockets to protect valuables.

BlocCopper or BlocWiFi?

BlocCopper is the same fabric as BlocWiFi, in a copper color instead of silver. Both are solid weave fabrics with the same shielding, so choose the color you prefer.
