Constructing an RF-shielded secure facility or secure compartmented informational facility (SCIF) requires the installation of a variety of building shielding materials.  In addition to our proprietary RF shielding window films, Signals Defense offers several of the most common RF attenuating products such as RF paint, radiant barrier foils, electrically conductive aluminum tape, RF caulk and RF wallpaper. Architects and security professionals specify and recommend these products to help keep data secure and reduce EMF interference.

Signals Defense attenuating RF and IR window films, including SD500, SD1000, SD1010, SD2500, and SD2510 provide exceptional anti-eavesdropping security.  Our SD 2510 and SD1010 films includes a safety film layer for protectiona against glass fragmentation and spall control.

The Science of RF/IR Window Shielding: How It Works

If you work with confidential or classified data, then you already know how important it is to keep such information secure – and window shielding films can help prevent exposure of such information to those outside of an office or building. But have you ever wondered just how these films work to keep data secure?

In this post, we’ll take a closer look at just what RF/IR shielding films are, how they work, and why they’re important in your office building. Here’s a closer look at what you need to know:
