I read the article a few days ago. It was a German company but not German sheetrock. The crap was made in China. Pretty suprising because the German contruction standards are incredibly anal - they build their stuff to last forever.
I think this Chinese drywall had a lot of sulphur which I believe is corrosive plus gave off fumes.
You mentioned FL. Lennar was mentioned in the article and their HQ is in Miami. They always have some problem for some crappy building or scam they have pulled.
something to keep in mind when I invest in FL real estate to take advantage of the coming flood of baby-boomer retirees...
