Hakan,
the foamed, aerated concrete has one difference to AAC, in that the cells
are sealed. AAC (Hebel, or Ytong) tends to have more porous structure. I
agree that the way you are talking is better, using insulation Gypsum
sheet.

Doug,
I am a bit tired today, otherwise I will be happy to explain the
principles for what I suggested in detail. The following which
is a part of a discussion about windows, do cover the principle
and if further explanations, ask and I will explain further.
When it comes to double glass
.
It is much better to put the generator's exhaust end on the outside of the
building.

One thing
JD,
I could only see the word acoustic in a few places, but nothing
with substance. Unfortunately a lot of people think about acoustic
as something magical, when it in reality follow the laws of physics.
The problem is that very small construction errors, can make a
special construction
Hi;
Thanks to everyone for the response.
I contacted an australian company about the cellular concrete and they do
endorse it for use as a sound and thermal insulator. see
www.buildlite.com.au
Of more interest is the use of a tractor silencer or special silencer like
the salt water idea.
One thing has occured to me:I'm not suicidal yet but can you kill
youself on biofuel or wvo/svo fumes?

I can look at it and maybe come up with some advices, but need information
of what you mean by sound proof first. I also like to know the environment,
how it is placed etc. Describe the problems.

Cellular concrete is made by adding foam (which looks like shaving foam) to a
cement mortar mix. Check buildlite.com.au or other googled resources for
more info.

JD,
It is good that it is in the cellar, that make it easy to do vibration
insulation, which is dependent of the mass of foundation.
I need noise data, you should be able to get it from Changfa. It
does not matter, but dB in octave band with spread diagram is
best. Minimum you get is always
You need to control air temperature as well. As for vibration there are rubber
clad cork or polymer isolation mounts that are used by installers of equipment
such as air conditioning packages. Each square inch supports a certain weight
so you can determine what you need.

Doug,
Because chances are that it is not that effective as sound insulation
and rather the opposite, it will work like a microphone membrane.
Sweden has been leading in this field and it is a lot of manufacturing
of Ytong around the world, on license from the Swedish company.
Again, 35+ years

Kirk,
You brought up something very important and the reason for that many make
vibration insulation does not work. To have an effective insulation, it
must work like a spring with space for both upward and downward movement.
In many cases the designer do not realize this and over dimension
