Abstract

Windows for attenuating radio frequency (RF) and infrared (IR) electromagnetic signals, so as to prevent or reduce such signals from emanating from secure facilities (e.g., government and/or military facilities). Example embodiments relate to a window including at least first and second glass substrates, at least first and second low-emissivity (low-E) coatings for blocking at least some IR and RF signals, and at least one transparent conductive oxide (TCO) inclusive coating for blocking at least some RF signals. The TCO inclusive coating may include a layer of or including indium-tin-oxide (ITO) located between at least first and second dielectric layers.
