In the lawsuit filed on Friday Banner alleges that Knauf Gips made false claims about the quality of the drywall. The lawsuit also contends that Knauf knew the odor-emitting sulfur in the drywall would damage other housing materials, such as wiring and metals.
Banner says it has been forced to pay nearly $55 million to homeowners in a settlement over the drywall. Banner attorneys say Knauf has contended it isn't subject to U.S. laws because the drywall was made in China.
The lawsuit was filed in federal court in New Orleans. A Knauf spokeswoman in the U.S. didn't immediately respond to an email seeking comment.
