It appears that the Chinese drywall problem might now be a domestic problem as well. The following link is to a new article with claims about Synthetic Gypsum Drywall market by Georgia Pacific as GP Tough Rock. This product is made in the United States and Canada.

It was sold through 84 Lumber and produced by Georgia Pacific in the case that was filed in Florida. The action was filed Friday, April 24, in U.S. District Court for the Middle District of Florida, Ocala Division. The lead attorney for the plaintiff is Brian Warwick of the law firm of Varnell & Warwick in The Villages, Fla. Janet Varnell of that firm is a board member of the National Association of Consumer Advocates.

This is a brief summary of the complaint as found in the article written by Craig Webb is Editor of ProSales.

According to the suit, Michael Swidler--a builder who has worked 15 years for Lennar Homes, Eagle Homes, and Deluca Homes--ordered 289 sheets of GP ToughRock drywall from 84's Tavares, Fla., store in May 2006 to be used in building a house for his family. The Michael and Jill Swidler and their two children moved into the home in October 2006. 

In early 2007, "the plumbing fixtures and several silver picture frames in the plaintiffs' home started to corrode," the suit maintains. In January 2008, coils in the house's HVAC unit developed a leak. The coils were replaced, but in July 2008 they sprung another leak. The family's microwave quit working in April 2008 because a keypad stopped working properly, in August 2008 the Swidlers' year-old TV set died, and in February 2009 the dishwasher failed because copper wiring in the unit had deteriorated. 

"The smoke detectors in the plaintiffs' home randomly go off without cause, and the home has a strong sulfur odor throughout," the suit reads. "All the copper ground wires attached to every light-switch and outlet in the home have turned black and are rapidly oxidizing." And pieces of Jill Swidler's jewelry has turned black, it says. By mid-April 2009, the Swidlers moved out of the house. 

 I will try to findout more on this new entry into the toxic drywall fiasco.  It still appears that "Fly Ash" better known as Coal Ash is the main culprit.  Stay tuned for more information as it is discovered.  For right now I would just be careful when selling or inspecting a home that has been built in the past 7 or so years.  If you have any question or concern go with that "gut" feeling and bring in another set of eyes to help.
