Our Story

Signals Defense, LLC was founded in Owings Mills, MD in 1999 with the introduction of an innovative optically clear window film technology that provides high RF (Radio Frequency) and IR (Infrared) attenuation for RF Shielding and Thermal Imaging defense purposes. Signals Defense patented window technology has been engineered to meet stringent US Intelligence Community security requirements for facilities handling classified information.

Our technology is the de facto written standard for the US Government and for organizations desiring to properly secure locations handling sensitive and/or classified information. Signals Defense window films meet the TEMPEST requirement for the Intelligence Community Directive ICD 705 and the DoD Infrared and Radio Frequency Emanation Protection Standards. Signals Defense technology has been deployed on over 1,400 locations providing our clients (including Government Intelligence agencies, DoD, and Fortune 100 companies) with US DoD emission security systems. Signals Defense technology also provides safety and energy benefits to our clients with UV and glass fragmentation/spall control window films, SD glass, and polycarbonates.

Signals Defense's product line has evolved into a Building Shielding materials portfolio.  In addition to Signals Defense film technology which is extremely viable because it offers an element of security that no one else can currently provide, the company has expanded its marketing of other RF and IR shielding materials to include rFoil and paints.  Additional "shielding" products such as shades and blinds have been added and are designed to shield against harmul UV/solar energy and provide additional privacy. 

Signals Defense, your building shielding expert, is available to assist with any commercial or government building shielding. From security window films, to custom motorized blinds or decorative films, Signals Defense is your one-stop for building shielding and security.

Signals Defense, Inc. has been listed in the Blue Book since 2007.
