 ULTRA NT SCIF Barrier - SOLID vs rFoil - The facts you need to know side by side product comparison

Don’t be confused by lookalike names—demand the real protection. Choose NBS ULTRA NT SCIF Barrier.

The ULTRA NT SCIF Barrier – SOLID, featuring a minimum shielding effectiveness of 106.8 dB (100 MHz – 10 GHz), is exclusively available through National Building Supplies, LLC and our official website, ULTRANTSCIFBarrier.com. It is not sold by rFoil, Covertech, EcoFoil, Amazon, or any other unauthorized reseller. Accept no substitutes.

Key Features:

  • Provides minimum 106.8 dB shielding (100 MHz – 10 GHz)
  • Fully SCIF-compliant and IEEE-299 certified
  • Proudly made in the USA – BAA compliant
  • Independently tested and verified by MET Laboratories


In contrast, rFoil’s ULTRA NT Radiant Barrier provides only 85 dB minimum shielding effectiveness across the 100 MHz to 10 GHz frequency range. Despite this significantly lower performance, its product name continues to confuse consumers—implying a level of protection comparable to the NBS ULTRA NT SCIF Barrier, which delivers a certified 106.8 dB minimum shielding effectiveness over the same frequency spectrum.
