WINDOWS

TSSNJ'S EMI SHIELDED

ARCHITECTURAL WINDOW

In today's world, there is a growing need to include electronic security along with energy performance and aesthetic considerations in the list of factors that influence architectural window specification decisions. In the past, electromagnetic interference (EMI) shielding of a complete building perimeter has usually been accomplished by the use of solid walls incorporating continuous metal foils. For those building designers trying to avoid the unpleasant environment of windowless work areas, windows covered with thick wire mesh have been the only option available.

DESCRIPTION

A TSSNJ RF shielded architectural window provides EMI shielding in a conventional appearing high performance commercial window. Utilizing proprietary fabrication technology consisting of a thin metal film or a fine wire mesh, both highly conductive and highly transparent, is incorporated into the construction of the laminated glass unit.

Continuous metal contact is ensured from the transparent conductive film or wire mesh through the seal to the metal window frame, thus forming part of the building's continuous EMI shielding envelope.

SHIELDING EFFECTIVENESS

Both fabricated TSSNJ EMI shielded window units and the thin metal film and wire mesh have been tested to Mil-Std- 285 at independent laboratories for their EMI attenuating capabilities. To accommodate different levels of shielding needs, TSSNJ window units are offered in many versions. TSSNJ 80 is the higher performance version with a minimal shielding effectiveness of approximately 80 dB over the critical electro-magnetic frequency range. TSSNJ 30 is designed for applications where approximately 30 dB attenuation in the same frequency range is sufficient.
