Even in dry construction, everything is “under power” without shielding!

Shielding fabric HNV100 for use in drywall construction, timber construction, solid construction, … This shielding fabric fleece against electrosmog HF + NF is our highest shielding product from the professional sector. Effective against 5G!

The HNV100 from YSHIELD® is a thermally fine metallized fleece made of polyester. Developed for the effective, large-area shielding of high-frequency electromagnetic fields (HF) and low-frequency alternating electric fields (LF) from domestic electricity. When shielding radio (cellphone radiation, RF, WLAN, transmission masts, …) a high shielding effectiveness of up to 100 dB is achieved!

HNV100 is our highest shielding professional product for walls, ceilings and floors. What fits for the professional is also perfect for the “woken up” person who is sensitized to electrosmog, we thought. Therefore HNV100 is now also available for private use. We prefer and appreciate this fleece for its flexibility also in timber construction or solid wood construction, an area where classical shielding products such as shielding paints can reach their limits. Depending on the season, the natural material wood expands and contracts or contracts, which can lead to fine cracks in shielding paints and thus to a weakening of the shielding effectiveness. This can be effectively prevented with this shielding fleece HNV100.

HNV80 was previously available in width  of 100 cm. This new length of 90 cm will replace the previous version soon. This step was necessary due to the increasing shipping problems with packages longer than one meter.

Shielding netting for effective, high-quality shielding

This fleece can easily be stuck onto walls, ceilings, and floors. It can also be used as a wallpaper. HNG80 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: 90 cm
  • Length: Yard goods / 100 meter roll
  • Shielding effectiveness: 100 dB (production-related +/- 5 dB). All values provided apply for 1 GHz. Measurement from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006.
  • Grammage: 70 g/m²
  • Thickness: 0.16 mm
  • Color: grey / brown
  • Tensile strength: 50 lbf
  • Materials: Polyester, copper, nickel
  • Surface conductivity: 0.01 ohm (square resistance)
  • 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 RF), LF (low-frequency electric alternating field)

HNV100 shielding fleece for the efficient shielding of radio radiation (HF) and electrical alternating fields by domestic electricity (LF).

Processing of the shielding netting against electrosmog

If the netting is being used as an intermediate layer, we recommend sticking it onto the surface with the DKL90 dispersion glue. The wall and back of HNG80 need to be coated with a paint roller with DKL90. Stick the wet surfaces together, set them by hand (with disposable gloves) and press together with a rubber pressure roller without causing creasing. Work quickly and strip by strip so that the DKL90 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 ou shielding paints as an alternative.

Order quantity, revocation of the order and surcharge for short quantities

If the netting has been cut in pieces of 1.0 running meter as requested by the customer, it is not possible to cancel or revoke the order. For this reason, it is possible to request a free sample of the shielding netting. By ordering pre-finished products, waiving the statutory right to return goods is accepted.

Practice has shown that small quantities are not financially viable due to the continuously increasing costs of packaging and shipping. Therefore we are forced to charge a minimum quantity surcharge for small quantities up to 3 running meters. We ask for your understanding.
