Faraday Defense CYBER PRO-BARRIER Foil Barrier for RF Shielding | 85 dB

The Faraday Defense CYBER PRO-BARRIER Foil Barrier Adds an 85 dB RF Shielding Layer That Also Works as a Radiant and Vapor Barrier

The Faraday Defense CYBER PRO-BARRIER Foil Barrier is a 3-layer solid foil material with two solid aluminum layers, one on each surface, and a strong woven polyethylene layer. Faraday Defense rates it at a minimum shielding effectiveness of 85 dB from 100 MHz to 10 GHz (IEEE-299:1997). It comes 48 in wide by 1 ft long.

It's made for construction projects where you want an EMF, EMI and RF barrier between drywall, plus a radiant heat barrier and a vapor barrier in the same layer. Faraday designed it for SCIF (Sensitive Compartmented Information Facility) and RF tunnel applications and to provide a static-safe environment for sensitive electronic devices.

CYBER PRO-BARRIER Foil Barrier Features

85 dB Minimum Shielding Effectiveness

Faraday Defense rates PRO-BARRIER at 85 dB of EMI attenuation from 100 MHz to 10 GHz, tested to IEEE-299:1997 and ASTM D4935. Two solid aluminum surfaces give the material conductivity on both sides.

Two Aluminum Layers, Three Barriers

Faraday Defense states that the two aluminum layers provide EMP protection, a radiant barrier and a vapor barrier. Water vapor permeability is 0.01 perms (ASTM E96-05), and Faraday describes the moisture protection as great.

Reflects 97% of Radiant Heat

The highly reflective surface reflects 97% of radiant heat, with an emissivity of 0.03 (ASTM C1371-04A). Faraday also lists increased sound attenuation.

Woven Base Resists Punctures

A strong woven polyethylene layer helps keep sharp objects from puncturing the material. Faraday says the woven base is durable and gives the barrier its flexibility.

Tested for Building Use

Faraday Defense lists a Class 1 / Class A fire rating (ASTM E84-09), passing results for corrosiveness (ASTM D3310-00) and resistance to fungi (ASTM C1338-08), and no cracking or delamination in pliability testing (ASTM C1313-05).

Real-World Applications

Shielded walls. Add an EMF, EMI and RF barrier between drywall.

Secure rooms. Faraday designed PRO-BARRIER for SCIFs and RF tunnel applications.

Electronics work areas. Use it to help create a static-safe environment for sensitive electronic devices.

Practical Comparison

PRO-BARRIER Versus a Plain Foil Radiant Barrier

A plain foil radiant barrier is made to reflect heat. PRO-BARRIER also reflects 97% of radiant heat, and it adds a rated 85 dB of EMI attenuation, a 0.01 perm vapor barrier and a woven base that resists punctures.

PRO-BARRIER Versus a Sewable Shielding Fabric

A sewable fabric suits covers, drapes and small projects. PRO-BARRIER is a construction material for walls, built to work as an RF, radiant and vapor barrier in one layer.

Buyer Guidance

Planning Your Project

Each unit is 48 in wide by 1 ft long, so measure your wall area and work out the length you need. Faraday notes that the architectural specifications for a particular job take priority on which products to use and how to install them, so follow your project's plans.

This May Be A Good Fit If

• You're adding an RF barrier inside walls
• You want a radiant and vapor barrier too
• You're building a SCIF or RF tunnel
• You need a Class 1 / Class A fire rated material

Common Questions

Where Does PRO-BARRIER Go?

Faraday describes it as a construction material for adding EMF, EMI and RF barriers between drywall, and as a heat radiant barrier and vapor barrier.

How Thick Is It?

Faraday lists the thickness at 8.0 mils, plus or minus 15% (MIL-STD-3010C Method 1003).

What Frequency Range Is It Rated For?

Faraday rates it at a minimum of 85 dB from 100 MHz to 10 GHz.
