When it comes to EMF-protective clothing, the term shielding effectiveness is often mentioned - but rarely explained in a way that actually matters to the person wearing it.
At WOREMOR®, shielding effectiveness isn’t a buzzword. It’s the measurable performance behind every garment we design.
What Is Shielding Effectiveness?
Shielding effectiveness (SE) refers to a material’s ability to reduce electromagnetic radiation by reflecting and dissipating incoming signals. It is typically measured in decibels (dB) and expressed as a percentage of signal reduction under controlled laboratory conditions.
In simple terms:
-
Higher shielding effectiveness = greater reduction of EMF exposure
-
Consistent fabric construction = reliable, repeatable performance
This measurement helps bridge the gap between how a fabric feels and what it actually does.
Why Fabric Construction Matters
Not all shielding fabrics perform the same - even if they contain silver.
Shielding effectiveness depends heavily on how conductive fibers are integrated into the textile, not just whether they’re present. In WOREMOR® garments, the silver yarn is woven throughout the fabric, creating a continuous conductive network across the coverage area.
This structure allows the fabric to interact with electromagnetic fields more efficiently, improving signal attenuation across a broad range of frequencies commonly encountered in daily life, including:
-
Wi-Fi and routers
-
Cellular and 5G signals
-
Bluetooth-enabled devices
-
Smart meters and ambient wireless sources
Designed for Real-World Exposure
Laboratory testing provides critical benchmarks, but everyday exposure is dynamic. Signals come from multiple directions, at varying strengths, throughout the day.
That’s why shielding effectiveness alone isn’t enough - the fabric must also maintain:
-
Full surface coverage
-
Consistent contact with the body
-
Flexibility that doesn’t compromise performance during movement
WOREMOR® apparel is designed with this reality in mind. Its form-fitting yet breathable construction helps ensure the shielding fabric stays positioned where it’s needed, without feeling restrictive or technical.
Comfort Supports Performance
A garment that sits in a drawer doesn’t shield anything.
Effective EMF protection must be wearable for extended periods. The soft, lightweight nature of WOREMOR® Soft fabric supports long-term use without irritation, overheating, or stiffness - key factors that directly impact whether protection is actually maintained throughout the day.
By combining shielding effectiveness with comfort, WOREMOR® designs focus on practical protection, not theoretical performance alone.
Interpreting Shielding Claims Responsibly
It’s important to understand that shielding effectiveness percentages are based on standardized test conditions. Real-world environments vary, and no garment can eliminate exposure entirely.
What shielding clothing can do is meaningfully reduce overall exposure levels, particularly from close-proximity and body-adjacent sources. This reduction is often what matters most for people seeking everyday, wearable protection.
At WOREMOR®, we aim for transparency - providing materials and designs that are both scientifically grounded and realistically wearable.
Protection You Can Wear Daily
Shielding effectiveness isn’t just a number - it’s the result of material choice, fabric engineering, garment design, and comfort working together.
Our apparel reflects that philosophy: a technically capable shielding layer, built into a piece of clothing that feels natural to wear every day.
Because real protection isn’t about extremes - it’s about consistency, comfort, and informed design.
