Shielding Fabrics

Protection looking good!

Shield yourself against -

  • High frequency (HF) electromagnetic radiation (EMR) from mobile phone transmitters, radio and TV transmitters, general electro-pollutants, like neighbour's cordless phones (esp. DECT)

  • Low frequency (LF) electric fields from the power grid.  This can be caused by home wiring and appliances, neighbours, power lines.

We stock protection for every purpose imaginable (paints, wallpapers, curtain material, window tinting, building). All shielding is based on metal surfaces, graphite, or fine metal mesh, woven into the textiles.  Some fabrics are very light and permeable, others are denser and more suited to clothing.  Please contact us for materials not listed here.

Fabrics are effective to 99.9999 % reduction in radiation intensity.  Depending on your needs, you may chose a fabric that feels just like any other cotton material. 

Fabrics can not be returned, so choose carefully.

If you are not sure about the right choice for your situation, feel welcome to phone or email. 

  • ALL PRICES ARE PER RUNNING METER, orders need to be for 1m, minimum
  • DISCOUNTS APPLY FOR ORDERS OVER 3m (with small amounts, freight is relatively more expensive, - at times more than the fabric, itself)  Please email for a quote.

Other fabrics are available, - this is our selection of 'favourites'.

Metallised Netting HNG80

  • Description
  • More Details

Compact woven, metallized polyester netting, 80 dB attenuation (99.999999 % shielding effectiveness). 

Our standard product for universal interior usage, especially suited for building into walls or floors.

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!

Pleae 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.

  • Width 0.66m
Technical data

  • Width: 66 cm
  • Length: By the meter / 30 m roll / 100 m roll
  • Attenuation: 80 dB at 1 GHz
  • Weight: 80 g/m²
  • Material thickness: 0.07 mm
  • Color: Anthracite / Brown
  • Tensile strength: Very good in both directions, 220 N/mm
  • Materials: Polyester, copper, nickel, protection coating


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.
