Mark,
Could you please mention some trade names for AAC? I did a lot of
looking (Google) for both AAC and Hebel in the Southeastern US about
three years ago with a notable lack of success. I found references to
a company south of Charlotte, NC, but it didn't lead anywhere. A later
look didn't even show them 8-(. I understand blocks of the stuff
are/were a stock item in home stores in Europe.

Thanks,
