I have seen this stuff. I think material, density, how its applied all matters. I have investigated foils, fabrics, paints. They can all work. Maybe great to make a copper foll liner in the rack and attach a ground box to it.You don't need to spend 50K. Faraday cages or equivalent can be had for a fraction of that in all sorts of sizes
Shielding: RF & LF Electromagnetic fields. -Anti-radiation（RF/EMI/EMF/LF blocking and earthing）. Surface resistance : below 1 ohm. Material: 100% silver fiber. -Washable (Better not wash too often and hands washable in pure cold water. ).www.ebay.com
Our Faraday fabric uses metallic copper, metallic nickel composition, and Polyester fiber materials that efficiently block 99% of wireless frequencies such as electromagnetic field (EMF) and electromagnetic interference (EMI). This guards you against potentially harmful frequencies and possible...atmosure.com
I pretty consistently believe its better to keep noise out rather than try and remove it.
