Check out the link below. I bet it makes more difference than a dedicated electrical circuit.

Though I'm sure this is a new and innovative product (and possibly better), there has been paint around for a while that does this. It is impregnated with copper and you have to ground the painted wall for best effectiveness.If you have that much rfi coming in through your walls, then your whole neighborhoods power grid is picking it up like a big antenna. And even a dedicated power line isn't going to help you. On the other hand creating this reflective cage in which to live will probably magnify your own generated RFI. Want to get cooked when you use the microwave? ;-)
I remember there were some theater owners who petitioned the FCC to be able to block wireless because of cell phones...but they were not permitted to do so...
or more appropriately the metal mesh that the stucco is applied to.kinda spoils the effect though if you have to run an antenna outside the room to pick up a signal.
also doesn't do much for the RF generated inside the room.

. . . does this stuff reflect RFI or absorb it?If the stuff reflects RFI, then as some (only half-jokingly) have suggested you painted your room with the stuff you might be reducing some RFI problems only to exacerbate others.

I know you were kidding, but oddly enough you probably don't need to if you have new windows.I just signed up for Clearwire internet a few weeks ago and it's a 2.4GHz wireless scheme using a modem with a very directional antenna built in. I discovered that our relatively new, low heat transfer windows blocked the signal. I suppose that they use a thin layer of metalization as a heat mirror or something.
So they are "quieter" in more than one way!
I was working for Emhart Chemical Group (been bought/sold/ & moved several times since then) in the early eighties and we had developed a metal impregnated paint for the same reasons - RFI rejection. The stuff weighed a ton and was either a two part epoxy or urethane based. I think we used iron or steel dust as the active ingredient. It was very expensive and reasonabley effective. Blocked AM & FM, no reception within the room that had been treated.
Several years ago I discovered (and wrote about) ERS sheets, a phenom that gathersd and absorbs broadband RFI in any vicinity. Apart from the fact that it can be overdone, it's been a benefit in any system where I've tried it. Hence no need, perhaps, to redecorate the room.clark
This raises a concern about richoceting RFI.As a film shooting photographer, I travel a lot, frequently having to get film past the TSA folks in airports. I don't want them to scan my film because unused film from previous trips is in the mix. If I kept running the film through scanners, it would eventually fog from accumulative exposure. I get hassled when I ask for a hand check of a hundred rolls at a time.
So clever manufacturers devised these lead foil lined bags that people could stuff their film in so it could ride the conveyors through the x-ray scanners.
Not a good idea.
What was found is that film fogs quicker in the bags. Some x-rays still get inside the bags, then bounce around off the inside foil, passing through the film many times. Its like a shootout in a John Wayne western, except that eveybody gets hit many times over.
If you have a wireless internet broadcaster in your house, maybe this paint isn't a good thing.
My understanding of the situation is that the operator sees the lead-foil pouch, can't see in it, and turns up the gain on his x-ray machine until he can . . . bye bye film. Can happen in checked baggage, too.
< < If you have a wireless internet broadcaster in your house, maybe this paint isn't a good thing. > >If you have a wireless internet broadcaster in your house, you are already compromising your sound quality. The paint would help defend against your neighbors' wireless internet broadcasting. Spend a few hundred dollars and have a wired network installed. (Or do it yourself for cheap.) Your stereo will sound better, and your house will no longer be a low-level microwave oven.
I did some research on RFI a while back and found two or three companies that claimed (and I don't dispute it) to make an RFI-reducing paint. This was at least two years ago.
I can think of a LOT of applications for that!

How ironic that we've come full circle. :^ )
It's for blocking RFI, not X-rays or nuclear radiation.se
Sorry. Didn't catch it at the time.se
Yes, when I read the article and saw it was a paint that blocks out wavelengths, the first thing that came to mind with the words paint and blocking was lead, and I thought how ironic it would be if after all the fuss about lead based paints they started using it again. Seemed pretty typical of all mans endeavors. :^ )(just don't eat it or lick the walls)

Too sadly too true. :(

But I think various coatings have been around for years to help shield electronic products from RFI. I'm not clear on what sets this company's product apart from the others.Visit google.com and search on "RFI Coatings" which will return a bunch of hits.
That is a serious home run. Imagine having the patent on that...
