Any building material can be overwhelmed by mold, given the proper conditions. Products and systems can be
proof drywall? designed to incorporate increasing degrees of mold and moisture resistance. The best and most cost-effective
strategy to manage the risk of mold is to prevent the intrusion of water into the building. This can be accomplished
through good design, construction, and maintenance practices.
