Blocwifi is the best screening fabric for many reasons, not only does it cover the broad range of high frequency radiation but when grounded it is a fantastic low field blocker too. Please see the picture setting out the attenuation which I'm sure will please you. It is made from polyester, nickel and copper and lends itself well to under bed protection, blinds and curtain backing. It can be sewn. It is very strong and durable.

It does not work!
Beautiful material, but does not do block any signals. My mom is very sensitive to wifi and she has a meter that she uses to read how strong the signal is around her. I was very hopeful about this product and we held it up in front of the meter and there was no difference. I'm very disappointed. I had no intention of simply buying a small piece of fabric for $30.

Awesome product that actually worked. Tested with Acousticom 2 RF meter.
This is an awesome product. I tested with my acousticom 2 meter by wrapping it with the sheet and it completely silence it. So I install it on my windows, by layering my drapes. I have cell tower radiation coming in from the windows, and this did the job. On acousticom, it shows a reduction from .10 to .02 V/m.Also, the price is great for this product. Note, that this product will block out your window.

Very effective
This is taken from an email I sent to the seller (note, I didn't buy this on amazon, but directly from them)---I got the fabric a little bit ago (the package took some damage in transit to the USA, but the material came through unscathed). It took me a while to set it up in a trial configuration, since it'll be on the floor of my place under the couch and coffee table.If you remember, I have one of the 3 axis electro-smog detectors. Previously where I like to sit had regular bursts of ~25mW/m^2 or more, I think from my downstairs neighbor's router. With this fabric in place it's dropped to 2 or 3 mW... at the couch base. And that's in a non-enclosed space! Just 6 inches away I'm still seeing the bursts.This fabric is fantastic.Me---A little extra for this review, you DEFINITELY want a grounding cable. I have a kinda-weak grounding setup right now, and the way the fabric is laid out my heels can touch it, I have an all metal mac book laptop which actually makes a pretty excellent ground. I can feel a difference when I go to type on the laptop if my heels are touching the fabric (because the ground switches to me) so get a grounding cable and hook it up!
