window shielding

I'm wondering if anyone has shielded their windows with one of the films available from places like lessemf.com.   If so, was the shielding effective?  I'd also be interested in hear about the effectiveness of shielding fabrics to make curtains.  These products are quite expensive and it would be nice to hear someone say "they helped" before going ahead and investing in them.

I've used Clear-Shield and GlareShield window films from LessEMF.  Their shielding effectiveness is extremely good. However, I found that Clear-Shield scratches more easily than GlareShield.  I also had more difficulty getting all the bubbles out from between the glass and film with Clear-Shield.  Rubbing it to get the bubbles out is how I scratched it.  I'm sure that some of my problems were due to a lack of experience applying window films.  But, I had less trouble applying GlareShield.  The downside was that it was more expensive.  Unfortunately, it doesn't look like LessEMF carries GlareShield anymore.

I've also used Signal Protect clear film from Safe Living Technologies (www.slt.co).  It seems to be very similar, if not identical, to GlareShield.  All 3 do an excellent job of shielding (checking with a meter, they seem to be equivalent).

I've also used SwissShield Naturell as well as SHIELDON 240 fabrics, and they both work extremely well. I had the Naturell fabric hemmed, and was told that when sewing with a machine, the needle would sometimes hit one of the wires.  That caused small pulls in the fabric.  It isn't noticeable unless someone is looking closely near the hem.

I was reluctant and skeptical before I purchased these fabrics and films, but I am very happy with them.  They have made a big difference for me.

Many years ago we used the expensive RDF75 films by Biologa.
But after a while my. then electrosensitive wife, experienced troubles.
I could not measure any differences in radiation outside.
So I then hang this Aaronia A2000 glass fabric over it, and the complaints were gone.

See: http://www.milieuziektes.nl/Pagina68b.html
Also this film gives a depressing impression by its darkening effect.
In the image the left window has the aforementioned film, and the window at the right has this Aaronia fabric.
Notice, that the sky behind the Aaronia fabric looks much more clear.

Very good shielding is the double insulating thermo glass, which has a very thin meetallic coating inside, which gives a large shielding effect.

An afterthought.

When I encounter windows which are letting radiation through, I do not advise such films anymore, but recommend curtains of shielding fabrics, which are in many different sorts and types.
With curtains, one shields also at the same time the window frames, which are not shielded by using films.

Which curtain shielding fabrics do you recommend Charles?


Thanks, Kathy

Overhere we recommend www.yshield.de
For instance: New Daylite, or New Topas.

Thanks to everyone who responded to my initial inquiry.  I think I may go ahead and purchase a window film, but also buy shielding fabric to line curtains.  That way, I'll get at least some shielding when the curtains are open, and more shielding when they're closed.  This discussion has been very helpful to me.  

Ayre,

You do not understand.

With a film the look to the outside is depressive.

With the curtains, you can look right through. They are never opened.

Oh, you're right, I didn't understand.  So the curtains are sheer.  Okay.  I'll reconsider.

Most films are dark. However, the ones I mentioned previously (Clear-Shield and GlareShield window films from LessEMF, and Signal Protect clear film from Safe Living Technologies) only have a very slight tint.  I doubt anyone would be able to tell that the film was applied.  

When I first received them and held them up to the light, I was disappointed, and thought they were too dark. But then I discovered that the plastic backing that gets peeled off and thrown away was causing most of it.  

There are also some architectural window films such as Solar Gard's Panorama HiLite which are almost clear, and are metalized, so they should do a good job of blocking the signal.

Yers, but what about the window frames?
Ands the walls next to the windows.

Therefore I always advise to hang these curtains from wall to wall, and from top to bottom.
That way it is all shielded.
