What signals does TitanRF fabric block, and how effective is it?

TitanRF fabric delivers an average of 80 to 100 dB of attenuation, providing 100% shielding of WiFi (2.4 and 5 GHz), Bluetooth, cellular including 5G, GPS, RFID, and radio signals. Adding more layers increases shielding. It blocks RF, not X-ray.

Which TitanRF fabric should I choose?

Standard TitanRF Faraday Fabric is the all-purpose choice for most enclosures and DIY builds. Specialty versions including Flex, Flame Retardant, Shadow, and TerraDefend are made for specific requirements; see each product page for details or contact us for a recommendation.

Q: How much TitanRF Faraday fabric do I need, and can I order custom sizes?

TitanRF Faraday Fabric is 44 inches wide and cut to length by the yard, then shipped rolled in a tube rather than folded. Plan for extra material so panels overlap at every seam. Custom lengths are available on request — contact us for pricing and sizing help.

Q: How do I keep seams and openings shielded?

Connect separate sheets with TitanRF Faraday Tape and seal holes with TitanRF Faraday Patches. Overlap panels by about an inch and make sure the fabric makes contact on all sides. For wall installs, run multiple layers across every surface.

Q: Is the fabric washable or reusable?

We do not recommend machine washing the fabric. If it needs cleaning, lightly wipe it with a damp rag to remove residue rather than submerging or laundering it.

Q: How do I verify my enclosure is blocking signals?

Seal a powered device inside, then test from the outside. Place a call or send a text to a phone in the enclosure, check whether it stays connected to WiFi or Bluetooth, or take a measured reading with a signal or spectrum analyzer or an RF testing app. If anything gets through, re-check your seams, overlaps, and any cable openings.

Lab-certified TitanRF™ fabrics, conductive tapes, gaskets, and shielded components — the raw materials engineers, forensic labs, and DIY builders use to construct custom RF enclosures of any size. Cut it, sew it, tape it, seal it.

DIY & construction

Create Your Own Enclosure.

TitanRF™ fabric and tape make it easy to isolate devices, prevent tracking, reduce EMF exposure, and protect electronics from EMP. Fabric is sold by the yard and cuts and sews like ordinary cloth; conductive tape bonds pieces and seals every opening. Follow the build series below — then install vents, filters, and windows. New to it? Read the Supplies F.A.Q.

Part 1

Construct a Shielded Box

Build a box from standard materials, then line it with certified fabric, tape, and foam gaskets.

Part 2

Add a Shielded Air Vent

Install an EMI honeycomb panel for effective shielding while keeping excellent airflow.

Part 3

Add a Shielded Filter

Pass USB, Ethernet, and power through the wall to charge and transfer data — without letting signals in.

Part 4

Add a Transparent Window

Install a shielded window with transparent fabric to view devices while maintaining full signal cutoff.

Safety First

TitanRF fabrics, tapes, and related products contain conductive metals such as copper and nickel. They are conductive and flammable — keep them away from outlets, plugs, cables, and any source of electricity to reduce the chance of fire. Contact us with any questions about your project.

Faraday Supplies F.A.Q.

How much fabric do I need, and can I order custom sizes?

TitanRF Faraday Fabric is 44" wide and cut to length by the yard, then shipped rolled in a tube rather than folded. Plan for extra material so panels overlap at every seam. We also cut custom lengths on request — contact us for pricing and sizing help on your project.

Can I cut and sew TitanRF fabric like normal fabric?

Yes. It cuts, sews, and tapes like standard fabric and works on a regular sewing machine. Use conductive thread, and cover any holes or seams with TitanRF Faraday Tape so you don't lose shielding performance at the joins.

How do I keep seams and openings shielded?

Connect separate sheets with TitanRF Faraday Tape and seal any holes with TitanRF Faraday Patches. Overlap panels by about an inch and make sure the fabric makes contact on all sides — for wall installs, run multiple layers across every surface.

What signals does it block, and how effective is it?

TitanRF fabric delivers an average of 80–100 dB of attenuation, providing 100% shielding of WiFi (2.4 & 5 GHz), Bluetooth, cellular including 5G, GPS, RFID, and radio signals. Adding more layers increases shielding. Note that it blocks RF, not X-ray — airport scanners will still see through it.

Which fabric should I choose?

Standard TitanRF Faraday Fabric is the all-purpose choice for most enclosures and DIY builds. Specialty versions — Flex, Flame Retardant, Shadow, and TerraDefend — are made for specific requirements; check each product page for details, or contact us and we'll point you to the right one.

Is the fabric washable or reusable?

We don't recommend machine washing the fabric. If it needs cleaning, lightly wipe it with a damp rag to remove residue rather than submerging or laundering it.

Why does conductivity matter, and what safety precautions apply?

The fabric, tape, and patches contain conductive metals like copper and nickel — that conductivity is exactly what blocks RF. Because those metals are also flammable, keep the materials away from outlets, plugs, cables, and any source of electricity. If you have a nickel allergy, avoid direct skin contact.

How do I verify my enclosure is actually blocking signals?

Seal a powered device inside, then test from the outside: place a call or send a text to a phone in the enclosure, check whether it stays connected to WiFi or Bluetooth, or take a measured reading with a signal/spectrum analyzer or an RF testing app. If anything gets through, re-check your seams, overlaps, and any cable openings.
