National Gypsum is an American manufacturer having the same problems.
Acoording to them they are not...........
National Gypsum Company, one of the nation’s largest wallboard producers, is not part of the current construction problem involving imported wallboard.
National Gypsum’s wallboard operations are exclusively in the United States. The company has never imported wallboard, never rebranded wallboard, and never distributed imported wallboard.
The nexus of the current imported wallboard issues is Florida. National Gypsum has produced wallboard in the state for 50 years with no problems and, since 2001, has produced nine billion square feet of wallboard in the state. National Gypsum wallboard has never exhibited any of the characteristics of the imported board in question.
It is not unusual for a home to have more than one brand of wallboard in it. Typically, for residential installations, distributors will get an order for a particular size and type of wallboard and send what is available in their warehouses.
National Gypsum wallboard is clearly marked by “end tapes” which are removed before the drywall is hung. The plant code and the date and time of production along with the company name are also printed on the back of the board. It is easy to identify National Gypsum board on the face paper, too. National Gypsum board is the only wallboard that has tiny “Xs” printed on the face to provide guides for attaching the board to wall framing.
the chineese drywall is also clearly marked, it is not unusual for a drywall contractor to run short or run over grabbing a few sheets to finish a job may have come off a chineese supplied job on to a National Gypsum job mixing both boards an a project.
Check the back of the board when delivered to job before it gets installed
