TitanRF Faraday Fabric + D.I.Y. Shielded Enclosures

Frequently Asked Questions


  • How do I use this fabric to make my own enclosure for shielding electronic devices from radio frequency (RF) signals?

TitanRF Faraday Fabric can be cut, sewn, taped, and used like standard fabric. View the DIY instructional image for an example of how to build a RF shielded enclosure for a tablet or similar device.

  • What RF signals does this fabric block?

It is 100% shielding of WiFi (2.4 & 5GHz), Bluetooth, cell signals (4G LTE+), GPS, RFID, and radio signals with 80dB-100dB average attenuation.

  • Can you use this with a sewing machine?

Yes, you can use a sewing machine with our faraday fabric. We recommend using conductive thread and to also cover any holes/seams with our TitanRF Faraday Tape to prevent any performance loss.

  • Is this fabric washable?

We do not recommend machine washing the fabric. If you must clean, dampen a rag and lightly wipe away residue.

  • What are the best practices for this fabric being used to line walls?

We recommend using multiple fabric layers on all walls and having the fabric touch on all sides/seams. Use TitanRF Faraday Patches to seal holes and TitanRF Faraday Tape to connect multiple sheets of fabric.

  • Can you use fabric adhesive on this for indoor construction projects?

If applying the fabric to walls, you can use a standard construction adhesive on the first layer to tack it to the wall, but not in excess or on seams. The second fabric layer should not have adhesive applied, and the fabric layers should overlay by an inch. We recommend using TitanRF Faraday Tape to seal the seams.

  • Will it block airport scanners if I wrap it around an item?

No, this does not block x-ray. You need thick metal to do that.

  • Would mylar work just as well to shield an item?

No, the attenuation (the reduction of the amplitude of a signal) is much greater with our TitanRF Faraday Fabric compared to Mylar. Mylar at best can provide an attenuation of around 20dB. Our TitanRF Faraday Fabrics has a consistent attenuation of between 80dB and 100dB.

  • I am looking to make a modem/router slipcover with this fabric. Will that block the WiFi signal that allows the router to function in the house?

If you cover the router ENTIRELY with the fabric, then it will block the signal. But, of course, your router won't function after that. And by ENTIRELY, you must unplug everything and place the router inside of your cover, and roll the edges so there is a tight seal. If there is a cable protruding from inside the pouch to outside, it will not block. This is the same concept as our faraday bags.

  • Can I use this to shield a smart meter outside my house to reduce EMF?

We have many customers who purchase our fabric for this exact purpose with positive results, however, it may be difficult to shield 100% EMF because the meter emitting the signal would not be completely covered.

  • Can this be used as a shielded blanket under my laptop computer to block radiation?

You can use the fabric as a blanket to reduce EMF, etc., although you should not make direct skin contact if you have allergies to nickel.

  • How do I know if my enclosure is properly blocking signals?

You can use the Mission Darkness app to test the signal blocking strength of faraday bags or DIY RF enclosures. It allows the user to perform a test using WiFi, cell, and Bluetooth signals to determine whether the faraday enclosure completely or only partially blocks signal transmission. Look for "Faraday Test" in the App Store or "MD Faraday Bag Tester" in Google Play.

  • Can I purchase custom dimensions?

We offer custom lengths of fabric on request. The width is 44" and the length can be cut by the yard and shipped in a tube (rolled, not folded). Contact us to inquire about the price.
