Tempest Security Systems Architectural Glass has developed a range of security glasses called TEMPEST-IR & TEMPEST RF-IR- both laminates and sealed units - specifically designed to reduce the transmission of EMI / RFI (electronic noise), UV (Ultraviolet and IR (Infrared).

IR glass is manufactured and marketed worldwide exclusively by Tempest Security Systems.

TEMPEST-IR glass can be used as windows or glazed panels in conjunction with shielded external walls, internal partitions or enclosures designed to provide good attenuation using the "Faraday Cage Principle".

TEMPEST-IR glass can be used in the external and/or internal glazing of buildings, viewing panels in shielded cabinets, and OEM viewing panels to meet most shielding regulations.

The complete absence of any metal mesh combined with the other qualities listed below makes the product unique.
