Netting-HNG100/HF+LF Shielding/Interior Apps

100 dB attenuation (Shielding effectivness), two-layers 134 dB

HNG100 is a compact woven, heavy metallized polyester netting for the protection against high-frequency radiation (HF) and low-frequency electric fields (LF).

This professional product with more than 100 dB attenuation is typically used for ministries of defence, banking houses, laboratories, etc. Where competitors advertise with 100 dB, they ignore the fact that the attenuation usually drops to some 80 dB at higher frequencies which is identical to our HNG80 or HNV80!

We have produced HNG100 with a very high metal content. With a resistance/square of only 0.003 Ohm and a close mesh-width the HNG100 achieves real 100 dB even at high frequencies.

In case of processing HNG100 as an intermediate layer we recommend using our conductive dispersion glue DKL90 for adhesion. The wall and the backside of HNG100 should be coated with a paint roller. Insert the material wet on wet. Fix it manually (with disposable gloves) and press a gummed roller against the fleece to get a crease-free surface. Work quickly and strip by strip only so that the DKL90 glue does not dry. A crease-free adhesion is only possible on perfectly level surfaces! Structured surfaces (ingrain wallpaper, textured plastering) have to be smoothed.

Due to the highly conductive surface this material can be contacted and grounded easy to shield low frequency (LF) electric fields.
For professional grounding we recommend our Grounding plate Magnet - GM, in combination with Grounding cable GC-200 Plugged into Grounding plate Tube-GT/Attach to Heating Pipes for loose laying application, or our perforated stainless steel tape ELB for application in drywall constructions. For adhesion to walls use our Grounding plate Wall - GW with grounding strap EB-1 in combination with our dispersion glue DK90. Also available: 3 pin UK earth plug

Shielding attenuation
The shielding attenuation is regularly tested in our own EMC laboratory. We have measurement setups due to the following standards: ASTM D4935-10, IEEE Std 299-2006, IEEEE Std 1128-1998, ASTM A698/A698M-07. You'll find the PDF test report above on this page.
