Chinese Drywall

• Does your home have a strong smell (a sulfur or rotten egg-type smell)
• Do you have corroded copper coils in your air conditioner or are the coils black?
• Do you have KNAUF written on the back of your drywall? Go to your attic and look at the back side of the drywall for Knauf. This is the manufacturer’s ID, which identifies it as the drywall in question.
• Chinese drywall is thinner and lighter than typical drywall

Additional information:

• This specific drywall is made of waste from coal-fired plants. The material that wouldn’t burn was recylced into the drywall instead of being taken to a landfill.
• AMRC, an environmental engineering and testing company, says the problem is mainly in communities, not single family residences built on their own, like in Cape Coral or Lehigh Acres.
• The drywall was used in 2004 and 2005 because there was a high demand for building materials at the time and this was available and cost-effective.
• Don’t waste money on lab testing. If you went over the checklist above and suspect you have Chinese drywall, call an environmental testing company to come out and verify it. It can be verified for legal purposes without lab tests.
• Health effects are unknown, there is not enough data on the actual chemical compounds to make a determination.
