3M Counter Intelligence Window Film

Protection of your valuable corporate data

Home As we now know glass is the weakest link in insulating a building.  electromagnetic signals from outside sources can disrupt precision electronic equipment inside of the building,  While signals from inside  wireless  electronic devices can leak though the window to outside sources.  This window film is used in situations where shielding of window glass is critical, such as exterior signal interference or interior signal detection.  This film has a RF attenuation of 35 decibels, which is a reduction  of 3,000 times the signal strength going through the glass or coming into the glass.
