Sound- absorption or reflection

[David Brady]

As long as it's fire resistant/retardent, installed with fire retardent
adhesives, maintains the required volume (after insulation), doesn't
restrict the incoming airflow, etc. The Powertech folks are pretty
specific. It might be worth a call to them to see what materials they
recommend.

I wonder if a thinner- less then 2" of convoluted foam would do the trick?

In other words, after the insulation is in place, then the remaining volume must still be to spec. http://www.powertec h-gen.com/ images/PTSMH% 2015%20through% 2020.pdf David Brady '02 LXi, NC Ernie Ekberg wrote: David, I would also assume that if the new insulation is too thick and takes up too much room, that it would restrict air flow?
