What’s In the Drywall?
There is so much talk about tainted drywall, and homebuilders are getting pretty familiar with the problems caused by Chinese Drywall. Over the past few weeks, however, there has been very little information about what is exactly wrong with Chinese Drywall.
Finally, there is some news about this issue coming out of Florida (who, of course, has been monitoring the problem the longest).
Last week, Florida released the findings of its drywall investigation conducted by Unified Engineering, a private lab. Lori Streit, a principal scientist with Unified, had this to say in a letter about the findings:
There is a distinct difference in drywall that was manufactured in the United States and those that were manufactured in China. The Chinese samples contained traces of strontium sulfide inclusions and more organic material than the GridMarx sample (United States). However, it is not yet known if either contributed to the odor.
While the findings are only a “first step” in what could be a months-long investigation, according to Florida state toxicologist Dr. David Krause, the preliminary findings did at least appear to contradict assertions that waste products from coal-fired power plants were to blame.
More is certainly to come on this topic, but at least folks are now not in complete darkness.

There is a huge misconception that Hydrogen Sulfide is the only compound causing all the trouble. This has led to “inspectors” running around with H2S meters trying to determine if a home is contaminated. The problem with this is that there are at least 5 toxic sulfides being found on a regular basis in the contaminated drywall. Hydrogen sulfide is only one of those compounds. As a matter of fact, we have had laboratory results come back with as many as four of the toxic sulfides and not include hydrogen sulfide. In these cases the meters would have done no good.
It is very important to get this right. It would be a shame if someone had their home checked with a meter, given the all clear, only to find out down the road that their home was contaminated with other sulfides. The only known way to extract these contaminents is in a laboratoy setting , under controlled conditions. Therefore, if you suspect you have a problem, have the home inspected, sampled, and analyzed. Deal with a company that uses an experienced laboratory with proper protocol.
