It looks interesting, and I'm a BIG fan of acoustic damping and thermal insulation, but I notice they don't mention what all that stuff weighs.
 
What damping material and where

I'm stilling looking for some damping material. What have you found to be a good product and where did you get it?
 
If you look at their PDF catalog, they have weights listed in there for a typical installation...an entire install being 46 pounds for everything. An entire install for an RV-7 (also -9 I'm sure) is $964. They are located about 60-70 miles from me, so I might head over there in a few weeks and check out the operation.

I haven't used it in an airplane, but I used Dynamat in my truck. It worked pretty well, but it is very heavy. If is it in the plane, I would probably think about using just strips of it in strategic locations. But for heaven's sake please don't take any advice from me. I'm still working on my wings.
