HNG100 shielding netting for use in drywall or solid construction. A highly-effective attenuation is possible with this shielding netting against mobile radiations and electrical alternating fields. Shielding efficiency over 99,9999999% (98 dB). Width 90 cm. Effective against 5G!
The HNG100 by YSHIELD is a tightly-woven metallic mesh made out of polyester. Developed for effective protection from high-frequency electromagnetic fields (HF) and low-frequency electric fields (LF) from the house supply on large areas. The attenuation of radio (mobile radiation, WIFI, transmission masts…) can go up to 98 dB! HNG100 is a professional high-protection product.
Shielding netting for protection in professional fields
HNG100 can easily be stuck onto walls, ceilings, and floors. It can also be used as a wallpaper. HNG100 is best suited to ministries of defence, low-emission rooms (Tempest), data rooms and laboratories because of its professional screening attenuation.

Shielding netting technical information
- Width: 90cm
- Length: by the meter / 20 m roll / 100 m roll
- Shielding effectiveness: 98 dB (depending on production +/- 5 dB). All specified shielding attenuation values apply at 1 GHz. Measurement from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006.
- Grammage: 90 g/m²
- Thickness: 0,08 mm
- Color: grey/brown
- Tear resistance: 90 lbf
- Materials: polyester, copper, nickel
- Surface conductivity: 0.01 Ohm (square resistor)
- Grounding: Electrically conductive. Can be contacted and grounded to shield against alternating fields (LF)! You can find the corresponding components under “Grounding”. It is difficult to recommend anything because it depends on the usage. Please ask us!
- Application: Floors, indoor walls, ceilings
- Field type: HF (high-frequency electromagnetic field), LF (low-frequency electric alternating field)

Processing of the shielding netting against electrosmog
In case of processing as an intermediate wallpaper, for glueing we recommend a commercially available dispersion glue. The wall and the backside of the material are coated with a paint roller. Insert the material wet on wet, fix it manually (with disposable gloves) and use a gummed roller to get a crease-free surface. Work quickly and strip by strip only, so that the dispersion glue does not dry.
You can only apply the netting crease-free on smooth surfaces! Structured surfaces (wood-chip wallpaper, structural plaster, roller structure of paints) must be smoothed. If this is not possible, we recommend using our shielding paints as an alternative. The material can also be laid loosely, e.g. under floor coverings, or tacked up, e.g. in dry construction. Always work overlapping so that the strips for earthing are also electrically connected.

Order Cancellation | Request Free Test Sample
If the shielding material is customized and cut from the roll in increments of 1.0 running meters at the customer’s request, returns or cancellation of the order are not possible. Therefore, you have the option to request a free material sample – please request it BEFORE ORDERING custom-cut material!
All our shielding materials are highly advanced specialty products with outstanding performance. The resale of custom-cut shielding material of this performance class is either not possible or only possible with significant financial loss, and therefore legally falls under the exception to the right of withdrawal. By ordering custom-cut running meters, your right of withdrawal expires; by placing the order, you accept our cancellation terms and waive your right to return.
Fairness in Product Pricing
Surcharges for small quantities up to 3 running meters have been eliminated for reasons of transparency and fairness. The price per running meter is therefore always the same, with price advantages for larger quantities. To cover handling and packaging costs, we charge a flat fee of € 6,90 per cut.
Test Report & Expert Opinion on Shielding Attenuation up to 40 GHz
Many years ago, YSHIELD invested in its own professional EMC laboratory. Here, not only are test reports generated, but each batch is also tested daily. In addition, YSHIELD has all products reviewed by an independent, renowned expert. Double-checked for double security.
Thanks to the great HNG100 shielding fabric, the radiation levels in my flat have dropped to a normal level. Thank you for the great shielding fabric 👍
The HNG100 shielding fabric is really a great product, I have ordered it for the second time now. I am absolutely thrilled and can only recommend it.
I am totally happy with the HNG100 shielding fabric. It is a really great product and absolutely effective. I will order more of it.
