About YSHIELD EMR-Protection


Our products are the first choice of experts in the field of protection

from electromagnetic radiation (EMR).  All YSHIELD products are

tested and certified from Prof. Pauli in the microwave laboratory of the

University of the German Federal Armed Forces in Munich, Germany.








Our top-selling product for shielding from electromagnetic waves is our metal-free high-frequency shielding paint HSF54. This paint can be applied like regular wall paint and achieves an attenuation of 36 dB even with a very thin single-layer coat. Its unconditionally suited for interior and exterior applications. HSF54 is breathable, low-emission, free of solvents and fulfills the highest (ecological) building standards.


YShield High Frequency Shielding Paint HSF54


Electrically conductive primer coating for shielding of high-frequency radiation (HF) and low-frequency electric fields (LF). Based on a high quality pure acrylic binder. Highly breathable, very low VOC content, free of solvents. Our top-selling, well-established shielding paint, with improved formula since August 2011.


    Shielding attenuation: Attenuation of 36 dB (shielding effectiveness of 99.98 %) in one layer, attenuation of 43 dB (shielding effectiveness of 99.995 %) with two layers. 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.


    Perfect corrosion resistance: Most shielding products

 containing metal components are not adequately

protected against corrosion. Our shielding paints HSF54,

HSF74 and NSF34 shield without metal particles using

 a mixture of carbons. Therefore they offer perfect

corrosion resistance (no oxidizing) and long-term durability.


    Underground: Interior and exterior: Excellent adhesion

on various undergrounds like existing emulsion paints,

sheetrock, wallpaper, cement, plaster, masonry, wood, etc.




Easy to apply water-based paint for walls, ceilings, doors and other interior OR exterior surfaces. Very effective for blocking cell phone signals, CB, TV, AM, FM signals, radiofrequency radiation and microwaves. Tested highly effective up to 18 GHz!


Based on a high quality pure acrylic binder, this shielding paint offers a perfect compromise of excellent attenuation, high water resistance and good ecology. Good adhesion on many surfaces and substrates like latex paint, construction boards, cement, plaster, polystyrene, masonry surfaces, etc.

Frost-resistant liquid format, ready to use right out of the bottle. Easy to handle – brush or roll similar to ordinary wall paint - and still achieve an amazing reduction of 99% of HF-Radiation with only one layer. Dries quickly. Water clean-up.


Due to its holohedral carbon structure, without fibers or meshes, it offers consistent attenuation regardless of the direction of signal polarization, and a highly conductive surface. As a bonus, carbon is a good RF absorber. About 10% of Y-Shield shielding effectiveness is due to absorption. This helps reduce reflections and minimizes the risk from RF sources trapped inside the shielded area.

Important note about conductive paint and the National Electric Code:


There is nothing in the NEC which prohibits painting your walls with conductive paint. However, because this product does NOT carry a UL listing, some electrical inspectors,

by virtue of being the “Authority Having Jurisdiction” can require the homeowner to hire

an electrical engineer to certify that the product is safe to connect to the electrical ground. They can also require that a licensed electrician perform the ground connection. If your application requires an electrical inspection AFTER installation, you should check with

your local inspector BEFORE you proceed to avoid any surprises.

High Efficiency RF Radiation Shielding For Windows



Windows provide very little resistance to RF radiation, so as a first step to reduce your exposure it makes sense

to shield the windows.  The good news is that you don't have to replace the windows, which could cost thousands

of dollars!


This NSN film by Concord Films is Triple-Layered and contains particles of three different metals to make it highly

effectiive for RF blocking.  It's widely used by the US Military, law enforcement and the security industry for signal

blocking.  This is a specialty film that is not available on Concord Films various websites.



Provides nearly 90% reduction of RF radiation at broadcast and cell phone frequencies

(tested from 100 MHz to 6 GHz) with a single layer! (measured directly at the window). Higher levels

can be achieved with multiple layers.



Besides the high RF shielding efficiency, you get the other benefits that come with standard solar

window film including: improved energy efficiency by controlling heat gain or loss and invaluable protection against severe weather and burglary.



Rejects greater than 98% UV, cuts down on glare while still allowing plenty

of visible light. It can also save you money in the winter months by reflecting

manmade heat back into your home or building.


If you can wallpaper a room, you can shield your windows. Easy to trim to size

with scissors or blade. Optional professional installation available in most areas

at additional cost.
