RF Shielding Solutions for Reliable Signal and Radiation Control
Raybloc specialise in the design, manufacture, and installation of copper-based shielded enclosures for MRI rooms and other controlled environments.
Engineered and built in the UK, our shielding solutions are designed to provide maximum protection against electromagnetic interference (EMI), radio frequency interference (RFI), and external noise across a wide frequency range. This ensures the integrity of imaging systems, research facilities, and other sensitive electronic equipment used in critical applications.
Unlike many suppliers, Raybloc delivers a complete turnkey package: copper shielding materials, shielded doors, viewing windows, waveguides, filters, non-ferrous lighting, and even full quench pipe installations. Every project undergoes attenuation testing pre- and post-scanner installation to verify shielding effectiveness and confirm compliance with ISO standards and NHS regulations.
Industries That Require RF Shielding
Medical (Hospitals & Diagnostic Imaging Centres)
MRI rooms are particularly vulnerable to electromagnetic waves and external interference, which can distort scans and compromise diagnostic accuracy. Our copper-based Faraday shielding systems are designed to ensure that scanners operate at their full resolution and meet the highest standards of performance.
Research Facilities and Laboratories
From Nuclear Magnetic Resonance (NMR) studies to prototype development, research environments often demand unique shielding to maintain data accuracy. Our bespoke shielded enclosures eliminate noise from electromagnetic fields, enabling precise results under challenging environmental conditions.
Telecommunications and Broadcasting
Broadcasting studios and telecom facilities require effective shielding solutions to maintain electromagnetic compatibility (EMC) and prevent radio frequency interference. Raybloc’s installations ensure secure data transfer and protection against electromagnetic interference, keeping communication networks free from disruption.
Defense and Aerospace
Military, radar, and aerospace testing environments often involve strong magnetic fields and sensitive electronic systems. Our advanced shielding technologies provide EMI shielding and environmental sealing that safeguard classified data and protect sensitive operations under extreme environmental factors such as temperature extremes.
Industrial Environments with Sensitive Equipment
Factories and industrial testing sites increasingly rely on high-precision electronic components. By using carefully selected shielding materials, including copper, nickel-graphite, and conductive elastomers, Raybloc’s solutions minimise downtime and provide EMI control to maintain productivity in harsh environmental conditions.
4 Key Benefits of Professional RF Shielding Installation by Raybloc
1. Compliance with Industry and Safety Standards
All Raybloc installations align with NHS HTM requirements, ISO regulations, and global electromagnetic compatibility standards. With over 25 years of expertise in radiation shielding, we deliver shielding solutions designed to pass all audits and inspections.
2. Reduced Interference for Sensitive Instruments
Our copper shielding materials and conductive coatings provide effective RF shielding across specific frequency ranges. This ensures uninterrupted performance of MRI scanners, research tools, telecoms, and aerospace-grade electronic devices.
3. Protection for People and Equipment
Our systems are designed to protect both staff and costly imaging/scanning equipment from exposure to electromagnetic radiation. By including shielding waveguides/RFI gaskets in construction, every seam is fully sealed for continuous performance.
4. Improved Operational Efficiency
Much like our lead lined product range, Raybloc’s manufacturing approach and RF shielding material selection ensure reliable performance over time. Our shielding ensures reduced downtime, cost savings, and consistent operational output.

Our RF Shielding Design and Installation Process
1. Initial Site Survey and Assessment
We evaluate your site’s shielding requirements and design considerations, factoring in environmental conditions and any specific applications such as medical, industrial, or defence.
2. Design Planning for Optimal Performance
Our engineers select the best conductive materials (copper, conductive paints, conductive elastomers, or nickel-graphite composites) to ensure maximum attenuation. Designs include environmental gaskets and conductive paints and coatings for long-term reliability.
3. On-Site Installation by Specialist Engineers
Our West Midlands-based team delivers expert installation, incorporating doors, windows, quench pipes, and lighting. Shielding solutions limited to MRI use can be extended to broader electronic systems where necessary.
4. Final Testing and Certification
Every installation undergoes attenuation measurements and compliance checks. Certification is issued to verify effective shielding solutions across specific frequency ranges, ensuring durability against both RFI and EMC requirements.
Safety and Compliance in RF Shielding Projects
Patient and staff safety come first. All projects comply with NHS, HTM 58 hygiene standards, and electromagnetic compatibility regulations. Our brass, steel, and copper shielding materials and conductive elastomers ensure continuous protection under varied environmental factors, giving clients peace of mind that systems will operate flawlessly in critical applications.

FAQs
How do Raybloc’s shielding technologies compare to competitors?
Unlike generic systems, our shielding solutions are designed with copper, brass, steel, and conductive elastomers, sealed with RFI gaskets for optimum attenuation. We combine manufacturing capabilities with on-site testing to deliver effective RF shielding that outperforms off-the-shelf products.
Can shielding solutions protect sensitive electronic systems from internal and external interference?
Yes. Our shielding solutions not only block external noise but also contain emissions from electronic systems inside the enclosure. This ensures protection against electromagnetic interference in both directions.
Do you build enclosures for prototype or custom projects?
Yes. Our expertise extends to research labs, industrial test sites, and prototype development, where we provide shielded enclosures tailored to unusual layouts or specific requirements.
How do you verify shielding effectiveness?
We carry out compliance testing to measure attenuation across specific frequency ranges. Using calibrated equipment, we verify that the installation provides effective shielding and maintains electromagnetic compatibility for sensitive electronic components.
