Door Solutions Take Security Above and Beyond

Aug. 1, 2008

Typically built by government agencies, corporations, and technology companies, a SCIF (Sensitive Compartmented Information Facility) room or building provides a confidential space to store, use, discuss, or process sensitive information without risk of outside intrusion-physical, visual, acoustical, or technical.

In the United States all SCIF facility planning, approval, and accreditation is monitored by the Cognizant Security Authority (CSA). From floor plans to security equipment layout and even personnel clearance, a SCIF facility must comply with all CSA specifications in order to be accredited and approved for use.

Krieger's SCIF door assemblies not only meet CSA specifications but also outperform those provided by other manufacturers.

To start, all Krieger SCIF assemblies (including door, frame, seals, and threshold) are manufactured with a minimum STC rating of 50. This is done to effectively satisfy the CSA requirement that all SCIF doors perform (in the field) with an STC rating of 45 or better.

Most door manufacturers are unable to reach the necessary STC 45 rating because their door assemblies are created from individually unrated sound-control components (frames, seals, thresholds, etc). While these types of doors perform well in the ideal conditions of a laboratory, when working in situ1 they often lose as much as five points from their NIC ratings (field performance tests) due to subtle incompatibilities and differences. This means that a door assembly with an STC 45 rating will often perform well below STC 45 in the field.

Krieger manufactures the entire door assembly to test at STC 50, making the CSA requirement easy to achieve. In fact, Krieger confidently guarantees an STC/NIC difference of only four points.

Additionally, Krieger SCIF doors are plumbed in their frames to provide sufficient strength to stay completely aligned for proper performance of door alarm sensors and to ensure complete closure at all times. They are equipped with automatic door closers, as well as approved locks and access control devices. If hinge pins are utilized on the exterior of the door, Krieger treats them to prevent complete removal of the door. And if electric door strikes are called for, Krieger chooses only those manufactured out of heavy-duty industrial material.

Aside from SCIF assemblies, Krieger also manufactures assemblies that meet TEMPEST or Technical Surveillance Countermeasure (TSCM) requirements. TEMPEST is a term that refers to the investigation, study, and control of compromising emanations from state-of-the-art electronic equipment. Doors that require TEMPEST accreditation differ only slightly from standard SCIF doors and are typically formed from electro-galvanized steel sheets to disrupt the flow of electromagnetic emissions.

If you have a project requiring SCIF or TEMPEST doors, give Krieger a call. For well over 20 years now, clients like Northrop-Grumman, Boeing, Lockheed Martin, McDonald-Douglas, and countless government agencies both domestic and abroad have trusted Krieger to manufacture the door assemblies that keep sensitive information safe and secure.
