High-Performance RF Shielding Meets Thermal and Acoustic Insulation

Fi-Foil’s SCIF Barrier is designed to be used in Sensitive Compartmented Information Facilities (SCIFs). Fi -Foil SCIF Barrier is comprised of a tear resistant layer of woven polyethylene material bonded to – and sandwiched between - two highly reflective aluminum surfaces. The low emittance or reflective surfaces reduce radiant heat transfer. In addition to increasing sound attenuation and being a highly effective radiant barrier or reflective insulation, the product is also a vapor retarder.

The RF shielding material has two (2) outer layers of 99% Pure Aluminum Foil with an inner layer of Fiberglass reinforcing and Kraft paper, made in the USA.

RF protection increases sound attenuation and meets or exceeds minimum requirements for shielding effectiveness at 378 frequencies as tested by an accredited NSA-approved TEMPEST facility. RF Shield provides high-performance frequency shielding with an average RF Attenuation of 73 dB.
