KriegerShield
Radio Frequency Shielding
Krieger's radio frequency doors 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 requirements of NSA 73-2A (1 kHz, 10dB; 10 kHz, 20 dB, 100 kHz, 30dB, and 1 MHz, 40dB).
Tests and Certifications
IEEE 299 Standard
Division 8 Standard
NSA 65-6

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 1 1/2 Hours:

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 1/2 inch without portable ramps, allowing them to be used in any location.
Performance Combinations
KriegerShield radio frequency doors can be manufactured for multiple performance requirements including acoustical, bullet resistance, blast resistance or any combination thereof.
Hardware
