As wirelessly transmitted data has become widespread, the need to protect this data also increases. The obvious first level of protection is to secure the network; however, this does stop potential electronic eavesdroppers from seeing that the network exists. Utilizing Radio Frequency (RF) shielding glass within a building façade creates a Faraday Cage, which keeps any wireless data contained so eavesdroppers won’t know a network even exists. Prior to 2014, there was no standard method to test the electromagnetic shielding effectiveness of glazings; however, various modified IEEE 299 methods were completed using varying frequency ranges, antenna types/locations, enclosure environments and glass sizes, each depending on the equipment at the specific test location. ASTM F3057-14 was developed to standardize the test method such that attenuation results focus on the glass itself and not the framing system, so product comparisons can now be made industry wide. Viracon has completed testing using both a modified IEEE method and the ASTM method for various RF shielding glass products. The results will show that a transparent conductive oxide (TCO) product has better attenuation than a film product, along with providing better thermal performance and more light transmission for greater color selection.
