Product details
BlocWiFi Nickel and Copper Fabric: 70 dB From 100 MHz to 3 GHz
BlocWiFi is an affordable and effective EMF protection material made of nickel, copper and polyester. It helps shield your home against the radiation from cell towers, smart meters, WiFi routers and other wireless devices, with 70 dB of shielding from 100 MHz to 3 GHz. It is not see-through or breathable. Browse our full range of EMF shielding fabrics to compare options.
RFID Blocking Fabric
BlocWiFi is commonly used to secure against radio-frequency identification (RFID) fraud. It can also be made into a shield case for mobile phones, Bluetooth car keys and ID cards.
Solid, Opaque Weave for Windows
Because BlocWiFi is not see-through, it is a good option for home or office windows, where it blocks microwave radiation and helps minimize EMF in any room. Its solid weave also makes it suitable for shielding while you work with a laptop or tablet.
Make a Bed Mat or Faraday Cage
BlocWiFi is conductive, so it is an excellent material for creating a Faraday cage and shielding radiation in many ways. It can be used as a bed mat or placed in strategic areas for EMF protection, and it can be used to ground beds. If you would rather buy a ready-made mat, see our EMF/RF bed mats.
Sold by the Length
BlocWiFi is 54 inches (137 cm) wide and sold in 3.25 ft (1 m), 5 ft (1.5 m) and 10 ft (3 m) lengths. Your order is cut as one continuous length, so if you need a longer length, increase the quantity in your basket. Not sure which fabric is right for you? Try our sample pack of four.
BlocWiFi or Another Fabric?
BlocWiFi is a solid weave fabric, so it is not breathable. If you need a lightweight, breathable fabric, see BlocSilver®. If you prefer a copper color to silver, BlocCopper is the same fabric in a copper color.

Nickel, copper and polyester.
70 dB from 100 MHz to 3 GHz. 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.
BlocWiFi reduces and blocks emissions from cell towers, smart meters, WiFi routers and other wireless devices. Its published shielding of 70 dB from 100 MHz to 3 GHz covers cell signals and 2.4 GHz WiFi. Higher frequencies, such as 5 GHz WiFi and millimeter wave 5G, are outside that range. For published shielding up to 40 GHz, choose BlocSilver®, which provides 36 dB at 40 GHz.
