thank you alot guys... i wanted to build a wall out of two walls of brickearth stones(they have good isolating impact) and i wanted an airgap between them and the fiberglass inside that airgap...what do you think?...
how much should be the space between the two walls where the fiberglass comes in?
i have been at the isover site...they sont have that much mass in their fiberglass its way lighter...but nevertheless they say its better...im thinking of combining the brick with
"akusto 10" fiberglass, anyone has experience??
I noticed that you mentioned the AES convention. Does this mean that you have some technical background in engineering? If you do there is a isolation calculator (INSUL) from Marshall Day Acoustics that can give you a good idea of what the isolation will be. The demo only lets you enter gyprock as wall material, but you can change the material properties. Change the density of the material and make the wall one layer of the thickness of the wall. To start concrete is around 2160 kg/m^3.
I have some articles about concrete wall isolation but not the URLS. If you had your email address up I would have sent those to you.
This article may help you with understanding isoaltion:

Good luck!
