Shielding fabrics
Locked
 
|
There was some discussion about fabrics being used to create a shield fromcell transmissions thru the walls that I guess I missed. I have used a faraday canopy but found that it only took my cell phone down from 5 bars to 3which is only about a 40% reduction & not good enough to stop my brain from frying. I was going to go the shielding paint route but if there are fabrics out there that works well (better than a faraday)
I would like to know about it & where to get it especially if it is less cost. Which is the best fabric to use against micro waves? Thanks Ron |

Hi Bill
I had purchased the standard Farady canopy new. It was not the heavy duty one that Emil says works better. My cell phone maxes out at 5 bars & did only lower to 3 bars. My headaches continued in the canopy so my head told me it was not working too. So I need some WALL FABRIC to cover the wall & stop cell microwaves from entering my house. Previous discussions seem to say that they taped the clothto the walls & had almost complete blockage of signals. I need to know EXACTLY which fabric was used & where to get it. Thanks Ron |

The guy I know who is most serious about this glues extra-wide, heavy duty
aluminum foil. He feels that stapling it isn't as good because the staples penetrate. Overlap seams by at least 4 inches. You want the window screening in contact with the wall shield all around. You can use diluted elmers glue or wallpaper paste. Be careful around outlets etc. You should probably have the power off or some other protection. Having metal on the outside of the building too is a plus. But how do you know it's not an AC magnetic field causing your problem? Admittedly 3 bars probably is enough to cause symptoms, but none of this will stop magnetic fields if present. I should add that there's also some who say that one will not be healthy in a metal box. Stopping the signals is good, but there are natural signals that will also be blocked. You may get some relief (and worse cell coverage) blocking the walls only.

I meant walls and windows only (try windows first if there is metal in the
walls, like with stucco). But to really get to low RF levels the ceiling should be addressed too, and perhaps the floor.

The windows are where the most RF comes in. Blocking the walls & not doing anything about the windows is useless in my opinion. I put the shielding onthe windows only & has helped a great deal. I had a Building Biologist measure the frequencies also. Loni

> > Thanks Ron See AL100 at http://www.lessemf.com/fabric.html#2272 and Pure Copper Polyester Taffeta at http://www.lessemf.com/fabric.html#1212 There is ALWAYS some leakage (though gaps, seams, switch plates, etc). So, often an absorber material http://www.lessemf.com/fabric.html#259N is placed in the inside surface of the shielding fabric to capture any RF that has leaked inside the enclosure. Emil |
