The product, in the report: Toxic drywall

I purchased a new home 1 year ago. After living in the home for 1 year we discovered the HVAC system’s evaporative coils were black and corroded and leaking [REDACTED]. All other copper electrical wiring is black as well along with copper pipes that carry natural gas and water. The home was constructed in 2007.

The company’s comments, in its own words

(4/3/2012) USG Corporation: I am responding on behalf of United States Gypsum Company (“USG”) to Report No. 20120307-5779A-2147469487 in which a homeowner raises concerns about corrosion of copper wiring and HVAC systems in his home, which he believes may be due to the drywall installed in his home. The homeowner’s name and address are not provided in the report. Since the time of the report, the homeowner has directly contacted us, and we have visited his home. The homeowner informed us that he has sent samples of wallboard from his home to be tested by an outside lab. The homeowner requested that we not take samples from his home and, instead, await the results of his outside testing. We are happy to do that. We have also directly corresponded with the homeowner regarding additional information that would be helpful.
We will wait to hear from the homeowner before taking further action. In the meantime, we want to note that USG’s wallboard is made in North American and does not have the corrosive or reactive properties associated with some Chinese-made wallboard, a fact confirmed by testing done by the Consumer Products Safety Commission. For example, the CPSC reported that, as a result of its extensive testing, USG wallboard (as well as other U.S.-made wallboard) did not emit elevated levels of sulfur gases. See http://www.cpsc.gov/cpscpub/prerel/prhtml10/10243.html. CPSC testing showed that USG’s wallboard did not contain elemental (or orthorhombic) sulfur, which the CPSC has associated with corrosive drywall, and USG’s wallboard did not cause copper corrosion. See Oct. 28, 2009 CPSC Report, “Statistical Analysis of the Chemical Screening of a Small Sample of Unused Chinese and non-Chinese Drywall,” available at http://www.cpsc.gov/info/drywall/TabA.pdf, and May 28, 2010 CPSC Report: “Identification of Problematic Drywall: Source Markers and Detection Methods,” available at http://www.cpsc.gov/library/foia/foia10/os/EHESourceMarkers.pdf.

The company’s comments, in its own words

(3/29/2012) USG Corporation: I am responding on behalf of United States Gypsum Company to Report 20120304-A30C4-2147469590 regarding drywall in a home located at [REDACTED]. This home is owned by [REDACTED]. We are familiar with [REDACTED] and his complaints. [REDACTED] previously claimed that he had defective Chinese drywall in this home (not USG drywall) and was a plaintiff in the Chinese drywall multi-district litigation. [REDACTED] home was inspected, and no Chinese drywall was found nor were the reported symptoms of reactive Chinese drywall found (i.e., no sulfur smell or corrosion of copper piping).
[REDACTED] apparently now contends that he has USG wallboard in his home which he claims is causing health problems. However, there is no evidence to support that claim and ample evidence to the contrary. All testing done on USG’s wallboard, which is made in North America, shows that it does not have the problems associated with reactive Chinese drywall and certainly does not cause health problems:
• First, the testing done by an independent lab retained by [REDACTED] showed that the wallboard in his home (which he claims is USG board) has no detectable emissions of hydrogen sulfide. While we do not know if the wallboard tested was, in fact, USG wallboard, we do note that the test result is consistent with the CPSC’s own testing of USG wallboard. • The CPSC’s own testing of USG wallboard showed that our wallboard had “low or no detectable emissions of hydrogen sulfide.” In contrast, as reported by the CPSC, reactive Chinese drywall had significantly higher hydrogen sulfide emissions. • With regard to the carbon disulfide emissions reported by the lab used by [REDACTED] , those levels are within normal limits, as confirmed by the CPSC’s own testing. See http://www.cpsc.gov/library/foia/foia11/os/lblreport.pdf , at p. 41, and http://www.cpsc.gov/cpscpub/prerel/prhtml10/10243.html. Further, as reported by the CPSC, the presence of carbon disulfide is not a marker of reactive drywall. See http://www.cpsc.gov/info/drywall/ehefeb2011.pdf , at p. 71. • Another round of testing by the CPSC on USG’s wallboard shows that our board is not reactive. See http://www.cpsc.gov/info/drywall/LBNLphase2.pdf , at p. 10, Table 3. • We also note that [REDACTED] attaches pictures of mason jars with copper piping that he claims shows that the board in his home corrodes copper. It is impossible from the pictures to determine the circumstances of the testing or what is actually being tested. However, the CPSC conducted copper chamber tests with USG’s drywall and found that USG’s drywall did not cause corrosion of copper in chamber testing. See http://www.cpsc.gov/library/foia/foia10/os/EHESourceMarkers.pdf.
In sum, there is no evidence that the wallboard in [REDACTED] home is a problem and certainly no evidence that it could be causing health problems.
