Krieger Specialty Products
KriegerShield
Radio Frequency Shielding
Krieger's radio frequency doors and windows are used in installations where TEMPEST standards are required, or where there exists a need for a radio frequency barrier for high frequency shielding.
Radio Frequency Shield
≥ 60dB of shielding effectiveness in the electric, planewave, and microwave fields in the frequency range of 1 KHz to 18 GHz.

Magnetic field shielding performance meets the attenuation requirements of NSA 73-2A (1 kHz, 10dB; 10 kHz, 20 dB; 100 kHz, 30dB; 1 MHz, 40dB; 10 MHz, 50dB).
Tests and Certifications
IEEE 299 Standard
Division 8 Standard
NSA 65-6
MIL STD-285
Custom Manufactured to Your Specifications
Door Configuration
Single, or pairs of, hinged doors, in standard and custom sizes, manual or power operated. Assemblies can be tied into any type of shielding construction.

Frame Configuration
Krieger offers standard frame designs and can engineer special frame profiles to complement wall construction and architectural style.
Fire Labels and Positive Pressure
Up to 1½ Hours:
UL 10C, UBC 7-2, UBC 7-4 450° and 650° temperature rise, up to 1½ hours UL 10C

Smoke Labels:
Up to 20 minutes
Robust Seal
Krieger's unique radio frequency seal does not use a knifed edge found in other radio frequency doors, rather it is similar to robust weather stripping, dramatically increasing the door life while reducing maintenance costs.
ADA Compliant
Krieger's radio frequency doors meet the ADA threshold requirements of ½" without portable ramps, allowing them to be used in any location.
Data Center Doors
Krieger’s specialty doors feature radio frequency shielding and an acoustical STC rating to keep data, sensitive information, and IT operations safe.

The door’s optimal hybrid performance makes
it an ideal solution to enhance data center security. Hybrid doors are available with the following features:

  • 40 dB/STC 51 hybrid with 1 ¾" thick door panel
  • 60 dB/STC 51 hybrid with 3" thick door panel

“Your time and knowledge on today’s call with Boeing and Intertek to dissuade their failure of these 5 openings is truly invaluable and very much appreciated. Internally we gained knowledge of testing criteria and transmission values, as other attendees seemed to as well, which will optimistically lead to ultimate acceptance of this project’s materials. Our partnership with Krieger is treasured, this experience encourages our continued relationship with the general contractor and hopefully Boeing. THANK YOU!”
