Nena, the OSB is definitely a composite wood product that would have to have no added urea formaldehyde to meet the credit requirements. Does that answer your question?

Plywood and OSB that are exterior grade are not typically made with urea formaldehyde resins. (UF glues are not usually waterproof.) These often do contain phenol formaldehyde, a more water proof resin, which is not prohibited by the credit. I've heard that phenol formaldehyde doesn't off-gas at room temperatures the way urea-formaldehyde does, so that may explain why it is allowed here.
