aluminum foil

Drasko Cvijovic
As I said previously I am building an EMF safe home... Good shielding fabrics are extremely expensive, say 30 Euro per sq. meter, so I was thinking of using aluminum foil or wire net. But seems that they know why they charge so much, I am theoretically totally confused as I found out that aluminum foil makes very low shielding effect against RF, metal wire net with only 1 mm windows makes even less than aluminum foil (i.e... almost nothing), while the fabrics do more or less what the manufacturer claims. So it's a kind of a high tech stuff?!
Any explanation why aluminum and wire mesh doesn't meet theoretical expectations? Charles?

Dear Drasko,
Could you tell me a little about how you are building
the ES safe house? I may have missed previous info.
What materials are you using, and what kind of
electrical paramaters? Thank you. John

Thank you for your interest, John!
I am in the issue for years, but it could have been taht \i am missing
something! Generally I use the equipment available through Aaronia from
Germany = www.electrosmog.de ... I have their meters and the (expensive)
shielding fabrics. I am still in the phase of experimentng. For example, I
have now proven that concrete walls give no more than 1 dB per centimeter
(at say 1 GHz range).. Also I have found out that aluminum foil is ticky, as
I mentioned. I am now going to check the effects of metalic foil for windows
(UV foil). I have to try everything on, as much of the theory proves not so
practical....
Please suggest what particularly I could have been missing, any suggestion
might have been of a great help!

Hello Drasko,

- concrete walls give no more than 1 dB per centimeter

That is chinese to me.

We always talk about uW/m2.
Please read your chart.

I do not know what *butterscotch* has been added to your concrete,
but I measure a lot of high frequency radiation through concrete.
Especiallay from cordless home telephones according the DECT
principle.

Aluminium is not so good, because its reflection is too great
inside .
Better is an absorbing material.

See my website www.milieuziektes.nl and click on the english flag.

I have also mentioned solutions for windows.

PS. this Yahoo groups is very, extremely difficult when you have to
change your e-mail address.
I have changed from provider, from cable to ADSL.
I have even made new account and new Yahoo ID's, but Yahoo refuses
flatly to accept the other addresses.
In the account info, they are verified, and everything seems ok, but
nevertheless, not accepted.
This one I sent via the Yahoo page!
