I reference the International Mechanical Code, which highlights the importance of insulation and vapor barriers to prevent condensation on ducts, especially those conveying warm, moist air from bathrooms. I also share solutions from industry experts, like insulating and sloping ducts, and emphasize the need for continuous air barriers to avoid moisture problems. I encourage you to review the article for more detailed insights and solutions. Please don't wait for water damage to identify defects in duct systems.
