TitanRF™ DIY shielding
Faraday Fabric & Tape Estimator
Planning a DIY shielding build? Enter the shape and size of your enclosure and this tool estimates the TitanRF Faraday Fabric and Faraday Tape you will need — with two-layer construction, seam overlap, trim waste, roll-top closures, and the tape bundled with each fabric kit already factored in. It also compares roll sizes to find the lowest-cost mix.

01 — Run your estimate
Choose a shape, enter dimensions in inches, and set your layers. The estimate and a full breakdown of the math update as you type.
This estimator assumes the standard 44 in TitanRF Faraday Fabric, whose Pro kits include Faraday Tape. Our other Faraday fabrics seal with the same tape, but they are sold by the yard without bundled tape, and not all are 44 in wide — check the width on each fabric's listing, since a different width changes the estimate.

All six sides of a closed box are included.
How it's builtTaped seams
A closed box has 6 faces. Cut two layers, overlap panels about 1.5 in, and tape every edge.
Join 44 in fabric strips across the wall, taping each strip seam, then tape the perimeter edges.
Front and back panels, folded at the bottom (no seam), with two taped side seams and a roll-top closure.
Irregular or round shapes are wrapped in the smallest box that fully contains them.
Fabric layers
1
Basic
2
Recommended
3
Durable
We recommend two layers for full RF shielding (roughly 80 to 100 dB). A third layer slightly increases shielding and adds durability. More than three is rarely worth it, the shielding gain levels off while the cost keeps climbing. If you have an unusual requirement, reach out and we will advise.
Tape width
Auto-selected by size: 1 in for very small enclosures, 2 in or 2.5 in for midsize to large. 2.5 in gives more wiggle room for seam sealing; 2 in leaves less room for error connecting sheets. Tap to override. We also offer 6 in and 10 in tape, used mainly for commercial work and covering items directly rather than sealing seams.

Included tape
The standard TitanRF Faraday Fabric ships with tape (Standard yard: 3 ft sample; Pro and XL kits: 20 ft roll), which we subtract from what you need. Other Faraday fabrics are sold by the yard without tape.

Roll-top closure
For bags, the opening adds roll-overs of about 1 to 2 in each (we recommend 2) for a resealable RF seal.

Panels over 44 in
Box faces wider than the 44 in roll are pieced from multiple strips, adding internal seams and waste.

Lowest-cost rolls
We compare a larger roll against multiples of a smaller one and recommend whichever costs less.

02 — What you'll need
Fabric, tape & supplies
TitanRF Faraday Fabric
44 in wide, sold by the yard and in Pro kits up to 50 yd. One layer blocks roughly 65 dB; two layers reach about 80 to 100 dB.

TitanRF Faraday Tape
Conductive tape to seal every seam and overlap. Available in 1, 2, and 2.5 in widths, plus 6 and 10 in for commercial work.
Shop tape →
Supplies & accessories
Patches, gloves, foam gaskets, shielded vents and windows, and complete DIY cage kits to finish the build.

03 — How a build comes together
Step 01
Shape & layer
Cut two layers around your object, overlapping panels about 1.5 in at every seam.
Step 02
Seal the seams
Tape every seam on each layer. 2.5 in tape gives the most margin for a clean conductive seal.
Step 03
Reinforce & finish
Patch corners and stress points, and add gaskets, vents, or windows where the build needs them.
