Fabric SILVER-TWIN/HF+LF Shielding

Compact cotton/silver fabric, 57 dB attenuation.


SILVER-TWIN is a compact cotton/silver fabric for the protection against high-frequency (HF) radiation. Typical application as curtain, to sew clothes, handy bags, etc..

Special feature: The frontside is made of white cotton, while the backside is densely woven with a silver thread. Despite the extremely high attenuation due to the dark silver threads on the backside, this fabric has a light grey frontside!

Maximum high screening attenuation, even at very high frequencies!
