The special requirements of special purpose doors and windows may need a custom engineered model to meet your performance demands. With Krieger's years of experience and knowledge, our engineering department can create a product to meet your specifications.
≥ 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).

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.
Krieger's radio frequency doors meet the ADA threshold requirements of ½" without portable ramps, allowing them to be used in any location.
KriegerShield radio frequency doors can be manufactured for multiple performance requirements including acoustical, bullet resistance, blast resistance or any combination thereof.
New 1¾" Thick RF/Acoustical Hybrid Door!
We’re now offering radio frequency doors with 40 dB RF protection and an STC 51 acoustical rating—all in a 1¾" thick door panel.
Available in all standard builders' hardware materials and finishes. Latch and lock sets, panic devices, security and power operating hardware is also available. Radial bearing, cam lift hinges are available.
Our full range of custom finish options includes prime painted, wood veneer, stainless steel, specialty finishes, and more—all perfectly matched to complement your project.
Standard and custom sizes. Windows can be tied into any type of Faraday structure, including integrated vision lites within RF shielding doors.
Krieger offers standard frame designs and can engineer special frame profiles to complement wall construction and architectural style. Stainless steel construction comes standard.
