MRI & RF enclosures / Company comparison
National Shielding
vs. Universal Shielding
Two shielding specialists. A better decision starts with the exact room, installation scope and service needs.
The short answer
National Shielding and Universal Shielding both describe capabilities in the design, manufacture and installation of RF enclosures. National Shielding emphasizes family ownership, direct management access and services for testing, repair and verification. Universal Shielding supplies medical, military and commercial enclosures. For buyers, the deciding evidence should be a scope-matched proposal and a clear plan for supporting the room.[1][4][5][6]

Why shortlist National Shielding
A direct relationship.
A defined scope.
Consider National Shielding when you want to connect the initial room project to future testing and maintenance from the outset. Our service offering addresses practical issues such as doors, gasketing, penetrations and bonding, with verification after repairs. Ask us to include the support your facility actually needs in the proposal.[1][3][5]
Where Universal Shielding fits
Give the alternative
a fair evaluation.
Universal Shielding is a direct enclosure competitor with MRI and other RF room offerings. It publishes design, manufacturing, installation and testing capabilities. A fair comparison needs to acknowledge that overlap rather than awarding National Shielding an exclusive full-service claim.[6][7][8]

Before you compare quotes
Ask how your room will be supported years from now.
A quote comparison should account for future access openings, equipment replacement and serviceable components. Ask how each proposed enclosure can accommodate anticipated changes, what work needs specialist support, and when retesting is required. Pair those answers with a written service scope so the first installation price is only one part of the decision.
- How would a future equipment replacement affect the enclosure and the warranty?
- Which replacement door seals, filters or other service parts will the room require?
- Who will inspect and retest after penetrations or other building changes?

Answers before you choose
Frequently asked questions
Does Universal Shielding install and test its enclosures?
Yes. Universal Shielding’s published overview lists design, manufacturing, installation and testing. Do not assume that these services are exclusive to National Shielding; compare what is included in the individual proposals.[6]
Why include National Shielding in the bid list?
National Shielding combines RF enclosure experience with a published commitment to direct management access and documented testing and maintenance services. That makes it a relevant company to evaluate for both a new room and its ongoing support.[1][4][5]
What acceptance-testing details should I request from National Shielding and Universal Shielding?
Ask each bidder to specify the test method, frequencies, measurement locations, acceptance criteria and report deliverables. Confirm when testing occurs and who handles corrective work. National Shielding publishes on-site testing and documented results; the proposal should define the requirements for your particular room.[4]
Can National Shielding support an existing room after installation?
Yes. National Shielding offers inspection, troubleshooting, repairs and verification testing for shielding systems. When comparing support proposals, identify the affected doors, seals, penetrations or filters and ask what documentation and retesting will be included.[5]
Is National Shielding less expensive than Universal Shielding?
This comparison does not establish a price advantage for either company. Request quotes from National Shielding and Universal Shielding using the same drawings, installation responsibilities, testing requirements and service scope. Compare exclusions as well as the total.
What should I send National Shielding when requesting a comparison quote?
Send the project location, available drawings, intended use of the room and the shielding requirements you have been given. Include known site constraints, the target schedule and whether the work involves a new room, an upgrade or troubleshooting. The team can then discuss design, installation, testing and maintenance needs.[2][3][4]
