Some home builders already struggling in Florida's dismal housing market are facing another headache: The Chinese-made drywall they used is causing unpleasant odours and possibly leading to electric problems in dozens of homes constructed during the housing boom.

Homes under construction last year in Miami. In some developments in south Florida, odours from Chinese-made drywall are drawing complaints and health concerns from homeowners.

A handful of builders and environmental consultants are investigating whether the drywall, a wide flat board used to create interior walls, is emitting sulphur-based gases that may be corroding air-conditioner coils, computer wiring and metal picture frames.
