A190 Shielding fleece
The A190 shielding fleece is a mechanically highly stable cellulose fleece that is laminated on one side with a thick micro-needled aluminum foil. The micro-needling with 200,000 tiny holes per square meter makes the material highly permeable to water vapor.
The micro-holes are so small that they have no effect on the sensationally high shielding attenuation of 112 dB - the highest shielding attenuation value we have ever had in a series product.
Produced in-house in Germany.

Application
Due to its good surface stability, moisture resistance and high tear resistance, A190 can be used universally indoors in all conceivable applications. Only suitable for loose laying if the aluminum layer is protected against mechanical damage.

Shielding attenuation HF & LF
This product shields high frequency electromagnetic fields (HF). Unless otherwise stated, the indicated dB-values apply to 1 GHz. Measurement from 600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006. This product with an electrically conductive surface shields low-frequency alternating electric fields (LF).
