HNG80 Metallised Netting
Our standard product for universal interior usage, especially suited for building into walls or floors.
80 dB attenuation (99.999999 % shielding effectiveness).
HNG80 is a compact woven, metallised polyester netting for the protection against high-frequency radiation (HF EMR) and low-frequency electric fields (LF EMF).
Our standard product for easy bonding on walls, ceilings and floors! This professional product is typically used for ministries of defence, banking houses, laboratories, etc. Now available for private use!
Please note that this material is stiff and can't be folded, like fabric. This makes posting small amounts uneconomical. If you would like less than 4 m, please email us to negotiate freight and packaging costs.

Processing
In case of processing HNG80 as an intermediate layer we recommend using our dispersion glue DKL90 for adhesion. The wall and the backside of HNG80 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 DK90 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. If that is not possible, we recommend using our shielding paint HSF54.
Grounding
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 plug EST for self laying application, or ourgrounding strap EB in combination with our grouding set ES for adhesive bonding with our dispersion glue DKL90.

Shielding attenuation
The shielding attenuation is regularly tested in our own laboratory or by Professor Dipl.Ing. Pauli at the University of the German Federal Armed Forces in Munich due to the standards ASTM D4935-10 and/or IEEE-STD-299-2006. The line in the diagram stands for the radial direction of polarisation (both directions, horizontal/vertical) and indicates the attenuation achievable in practice. You find the expert report above.
