Shielding materials and products are diverse. And extremely rich in essential technical details - a dramatic disadvantage for the layman. A small change in numbers in the screening attentuation report can ultimately mean a huge difference in measurement technology. EMF shielding classes create the common thread.
In the ULTRA performance class, the focus is on MAXIMUM. Only highly developed shielding materials create our metrological requirements for the SFERICS® ultra classification. When every single dB counts!

Shielding materials and products are diverse. And extremely rich in essential technical details - a dramatic disadvantage for the layman. A small change in numbers in the umbrella report can ultimately mean a huge difference in measurement technology. EMF shielding classes create the common thread.
In the PRO performance class, the focus is on HIGH. Purely highly developed shielding materials create our technical requirement for a SFERICS® pro classification. When above-average shielding is the goal!

“BLACK-JERSEY shielding fabric | ideal for making clothing, sleeping sleeve, etc. | HF shielding against electrosmog up to 40 dB | mobile protection against mobile phone radiation | 5G ready!” has been added to your basket. View basket
The stainless steel gauze V4A10 is ideal for effective EMF shielding with a shielding effectiveness of up to 40 dB. Due to its corrosion resistance, it is especially ideal for use as the basis of a basic shielding on exterior walls of the house – even in saltwater areas.
Price per meter (100 x 90 cm)
Quantity = number of linear meters
Shielding stainless steel gauze (mesh) V4A10 for flexible application inside and outside. The shielding fabric is corrosion resistant and insensitive to heat. With this shielding fabric against electrosmog HF + LF the highly effective radiation protection against electrosmog is possible. Shielding efficiency 99.99% (40dB). Width 90cm.
This V4A10 stainless steel mesh is a finely-woven and corrosion-resistant stainless steel mesh. It can be effectively installed to provide basic protection against electrosmog from radio (HF) and alternating fields from the power supply, for example (LF).
The shielding stainless steel mesh also impresses with its resistance to corrosion. It is ideal for house construction to protect the entire building, even near the coast and salt water. Importantly, the V4A10 stainless steel mesh is very resistant to water, steam, humidity, weak acids and salty seawater on the coast.
Typical use of the V4A10 stainless steel gauze
Inside and outside under the render in insulation, in the ceiling, in timber construction, dry construction, loose laying, and many more. Thanks to its 1mm-thick mesh, it can also be used as a fly screen against midges and mosquitoes, among others.

Grammage: 260 g/m²
Mesh thickness / mesh density: 1 mm
Wire diameter: 0.16 mm
Material thickness: 0.32 mm
Surface conductivity: 0.1 Ohm (square resistance)
Fire-proof material, A1 according DIN 4102:1994
Processing the V4A10 stainless steel mesh against electrosmog
When working under a render, this V4A10 stainless steel mesh should be stuck with the finest organic filler (without fillings) possible. When working under flooring (laminate, parquet, PVC, etc.), V4A10 is stuck on with the adhesive. In dry construction and ceilings, the tracks fasten or can be stuck on as required.
The following always applies: the tracks overlap for 5cm.
For grounding, our stainless steel tape is put on across all of the tracks and stuck to the substrate/tracks.
This product has multiple variants. The options may be chosen on the product page
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.
