- Is the question who is liable?
The installer is primarily contract labor, whatever you put in front of them they install.
They do not inspect it, 99% are laborers and will put anything up they are uneducated.
the subcontractor and?contractor purchase from a distrubutor and most of them do not ask where it comes from. since at the time there were no known defects they would not suspect anything.
The distributor has specs 3/8 in or 1/4 in etc and they also have quality control. But quality control is only looking for uniformity in the product.
But, if there is a warehouse full of this stuff that smells like sulfur it should raise some questions.
The manufacturer is totally liable because they buy the raw materials and should have a list of what it is made of
Sulfur is an inorganic material so it wouldn't be caused by sitting on the dock it would have to be in the raw materials they are using.
Drywall is made of Gypsum.? It could be a problem wioth the paper on the exterior of the gypsum and that would be the manufacturers fault.
Unless it has the sulfur in it, it can't come out of it.
