STEEL GRAY HF + LF shielding fabric – ideal for opaque curtains and textile products such as bedding and ceilings.
This shielding fabric was processed for our sleeping bag, linen and blanket for effective protection against LF and HF electrosmog. The fabric contains stainless steel threads and is therefore contactable, which means that LF electric alternating fields can be earthed. The HF mobile radiation screening attenuation is a high 35 dB and applies to high GHz frequencies.
STEEL GRAY is ideal for curtains and for products around the bed and couch because of its properties. However, it is less suited to clothing because stainless steel threads are not soft and comfortable on the skin as silver threads. At best, the feeling can be compared to an itchy wooly sweated. STEEL GRAY is very robust compared to silver fabrics and is therefore extremely durable. It can also be washed and ironed.
Use and assets of the STEEL GRAY
