Anti Eavesdropping Film (RF Attenuation Film)

Signal Defence window films provide radio frequency (RF) and Infrared (IR) attenuation with high visible light transmittance and low reflectivity – resulting in minimal aesthetic impact.

These Government and military grade protective films give high attenuation levels to glazed areas assisting in areas, which require conversion to Sensitive Compartmented Information Facilities (SCIF) standards.
