This Top Innovation profile describes research by Building America to diagnose the cause of moisture problems in manufactured housing in Florida and prescribe measures to mitigate the problem; in all, the researchers worked with 24 manufactured home factories between 1996 and 2003. The recommended measures included mastic sealing ducts, installing properly sized high-efficiency HVAC, thoroughly air sealing the building envelope, using water-resistant exterior finishes, and implementing positive pressure ventilation to keep out humid air.
In addition, the researchers provided follow-up technical assistance to the manufacturers to see that recommendations were implemented properly. One manufacturer reported zero moisture-related issues in 35,000 homes built after implementing Building America recommendations. Read about the Top Innovation.
