In what may be a smoking gun of the evidentiary sort, federal investigators have found a chemical difference in the composure of Chinese drywall when compared to those products made within the country. While the discovery has yet to be the clear-cut indictment of the manufacturers of the imported wallboard, it is significant because it shows a clear difference between that drywall causing problems and domestic drywall that remains to be safe and not a cause for concern.
The New York Times reports
Federal investigators reported Thursday that imported Chinese drywall that homeowners have linked to health problems and odors had higher levels of some chemicals than its domestic counterparts.
