Fabric STEEL-TWIN/HF+LF Shielding

Typical application as curtain, 41 dB attenuation

STEEL-TWIN is a compact cotton/stainless steel fabric for the protection against high-frequency (HF) radiation & Low-frequency (LF) electric fields. Typical application as CURTAIN.

Special feature: The front side is made of white cotton, while the backside is densely woven with a stainless steel thread. Despite the high attenuation due to the grey stainless steel threads on the backside, this fabric has a light grey front side!
Tip: Due to its front side made of pure cotton, this fabric can be coloured in the washing machine at 30°C (86°F) with fabric dyes from Chemists!

Good screening attenuation, even at high frequencies!
Excellent cost/performance ratio
Contactable (groundable) to shield LF electric fields
Textile characteristics: Washable, easy to iron and process
Quality grade: Very high
