Raw Silver Fabric S04 (Sold by meter)
A raw silver shielding textile for controlled prototypes, interiors, and builds.
Waitlist access
Colour: silver grey
Prototype format: textile dimensions and finishing confirmed at bulk production.
- S04 textile system with 60-80 dB (declared material value).
- Silver textile construction selected for the intended use case.
- Pre-launch candidate pending independent EU lab testing before preorder opening.
A professional-grade raw shielding textile for prototyping, interiors, garments, and custom EMF projects.
Every pre-launch Zanthera product keeps material performance, garment coverage, and final lab verification separate so the product page stays useful without overstating real-world exposure reduction.

Compliance & safety
Restricted-substance checked. Claim-safe by design.
Nickel-Safe
Guaranteed free of nickel-copper alloys (REACH Entry 27 compliant).
Restricted-Substance Tested
Silver fiber reviewed through EU lab testing against restricted substances.
Attenuation
Frequency response by signal family.
| Signal family | Frequency | Attenuation |
|---|---|---|
| GSM / 3G / 4G | 0.9 - 1.9 GHz | 60-80 dB |
| Wi-Fi | 2.4 GHz | 60-80 dB |
| Wi-Fi 5 GHz / 5G Sub-6 | 5 GHz / Sub-6 | 60-80 dB |
Declared material specs. Pending final independent EU lab testing.
EN: This product is not personal protective equipment (PPE) and has no medical properties. Attenuation values refer to the shielding fabric measured under laboratory conditions; actual exposure reduction depends on garment coverage and fit.
SV: Produkten är inte personlig skyddsutrustning och har inga medicinska egenskaper. Angivna dämpningsvärden avser tyget under laboratorieförhållanden; faktisk exponeringsminskning beror på plaggets täckning och passform.
02
Cut, layer, test.
Shielding performance depends on the continuity of the textile and the area it covers. We keep the data tied to the material so each build can be evaluated on its own construction.
