That's the portion of my "Threshold Inspection" I save for last. It's pretty hot and grimy in those attics here in SW Florida! But do remember guys.... ceiling board is always different than wallboard, on a properly built modern residence. Either 5/8" or 1/2" "ceiling board" per our codes here.... so unfortunately whether there is ceiling board from US or Chinese origin, it will not determine what was used on the walls. To complicate things further... there are now confirmed cases of US origin (labeled or barcoded) sheetrock that has similar negative components and offgassing! If interested, rRead my post at the link below for more info. (hope this is ok to post link... new here) American Drywall Issues Known since 2006!

That wouldn't work very well, as most of the defective sheetrock in question was used several years ago in Florida at least. *sp

Ouch..... sounds like yet another lead generation biz? Marc... Where did you see that figure btw? I just perused the article briefly.
