Electronic eavesdropping can be used to gain valuable and confidential data. This can pose serious and costly problems for businesses in today’s IT driven world. Data shielding glass reduces the transmission of radio frequencies (RF) and is sometimes known as RF shielding. In order to protect a building, a Faradays cage principle must be applied. This means all external surfaces need to be electrically conductive and then grounded. Since windows are an important part of the external façade, these must also be electrically conductive.
The result is that any radio frequency that is emitted from equipment rebounds back and stays within the walls of the building. It also prevents external electronic interference from entering the building.
The glass is often used in high security IT installations, television and radio stations, and security and computer installations.
