NATURELL-ULTRA™ from Swiss-Shield® is a semi-transparent cotton fabric for the shielding of high-frequency electromagnetic fields (HF) and low-frequency electric fields (LF). NATURELL-ULTRA™ is the second fabric of a new product series from Swiss Shield®. In the new ULTRA-series the silver-/copper-filament is coated with carbon, why these fabrics are electrically conductive to shield low-frequency electric fields (LF).

Semi-transparent cotton fabric
High screening attenuation for a cotton fabric
Can be grounded due to the conductive surface
Excellent cost/performance ratio
Textile characteristics: Washable, easy to iron and process
Quality grade: Very high

*Note: To purchase a custom length of fabric, please place an order for multiple quantities of the 1ft option. The amount ordered will be cut as a single piece unless specified otherwise.

Order quantity: This product is cut off according to your specifications, a return or revocation are not possible.

Screening attenuation: All stated attenuation values apply at 1 Ghz. Measurement to ASTM D4935-10 or IEEE Std 299-2006 or IEEEE Std 1128-1998 or ASTM A698/A698M-07. You find the test report above under "Report screening attenuation".

Grounding: Electrically conductive. Can be contacted and grounded to shield electric fields (LF). We recommend a plug GP or GD, with a plate GM or GS, plus a cable GC.

Application: Curtain, Window, Canopy

Field type: HF (High frequency electromagnetic fields)

Ecology: Very high
