This may turn out to be a stupid question, but I thought I'd ask anyway.

I am looking for materials that I could use in my wall to minimize sound transmission. So I looked into products that contain "vacuums" because sound does not travel through a vacuum.

Windows:
I first looked at windows and found that windows made with an "evacuated glazing" are very thin and have very good insulation and sound transmission properties compared to conventional windows. Unfortunately the process of creating these windows seems to be immature, so if you could find them, they might be expensive. links:

Walls:
I was much more successful in finding opaque insulating materials that contain a vacuum. However, the product websites focus in on heat insulation, rather than sound transmission. Also, some of these products seem to be used in refrigerators, rather than walls. (e.g. http://www.rparts.com/Catalog/Box_Build ... lation.asp )

Has anyone used "Vacuum Insulation Panels" in their walls and found them to be good *sound* insulators?

Thanks in advance for any feedback!

Hi,
I used Vacuum Insulation Panels but did not work as i expected as insulator.
