Chinese Drywall

What ISO policy exclusion under an HO3, if any, applies to a product defect? We have seen a couple of instances in Louisiana where the insureds are sustaining damage as a result of defective drywall made in China . This was used following Katrina to replenish shortages of drywall supplies.

The ISO HO 03 excludes loss to coverages A &B caused by faulty materials used in repair, construction renovation or remodeling. (See page 12 of the 10 00 policy.) Any ensuing loss as a result of the faulty drywall would be covered, for example if the drywall caused corrosion damage to wires or pipes.
