Faraday Cage Building Material
RF Shield Sheeting For Your Faraday Box or Room

TruProtect is a patented 95% recyclable aluminum foil and fiberboard sheathing which has some remarkable properties beyond its original development as a 98% plus effective radiant heat barrier. Michael Faraday would be proud.

Three layers of aluminum (0.13mm, .05mm, and .05mm) each separated by two layers of 6mm fiberboard and air spaces leads to TruProtect’s high test results for RF shielding. When the 4 x 8 foot panels are joined with 5 mil conductive aluminum tape, TruProtect provides a light weight, sturdy solution for radio frequency and electromagnetic shielding.

There are two types of matter that affect electromagnetic waves: conductors and insulators. When an electromagnetic force hits a material, some of the energy is reflected from the surface while some of the energy may be transmitted into and possibly through the material. The ability of an insulator to reflect the energy is called the Attenuation Coefficient of the material. The higher the Attenuation Coefficient the more effective the insulation, with 100 indicating a complete blockage.

An attenuation of 100 = complete blocking.

Many of the folks who contact us have raised the issue of being able to protect their electronic solar hardware like charge controllers and inverters from electromagnetic radiation.

Scientists are predicting that 2012 will be a particularly active year for solar flares from the sun, also called Coronal Mass Ejections. When gas erupts from the solar corona, the outer atmosphere surrounding the sun, a burst of electromagnetic radiation of sufficient intensity could create a sudden, massive fluctuation in the earth's electromagnetic field similar to the detonation of a High-altitude Electro-Magnetic Pulse (HEMP) nuclear device. This could both damage electronic and semiconductor devices as well as couple with electrical grid systems to produce damaging current and voltage surges.

TruProtect is being used to protect government, military and corporate secure facilities and information from electronic eavesdroppers. Examples include EMC, RF and wireless test facilities and labs; RF shield test chambers, recording studios, secure conference and meeting rooms; SCIF facilities; anechoic test chambers; computer rooms and data processing centers; RF secure buildings for law enforcement and security agencies.

TruProtect is also available in wire shielding tube configurations for telecommunications and data transmission.

TruProtect can also be backed with OSB or drywall for increased structural integrity to meet your construction requirements.
