Inflatable Retrofit Duct Liner
72483B03-I Ductwork arrays in existing homes are notoriously leaky, and their inside surfaces are often covered with accumulated dirt, debris, and various unhealthy organisms. Aerosol sealing systems can plug small leaks only, and other retrofit techniques require substantial demolition or deconstruction of parts of homes. This project will develop technology for inserting an inflatable liner into ducts of existing homes. The liner will form a new inner coating that eliminates leaks, encapsulates surface defects, and enhances air flow Â¿ without demolishing parts of the house or disrupting lifestyles. Phase I will consist of proof-of-concept research to verify the methods and materials for fabricating duct liners, for weaving them through ductwork, and for inflating and sealing them into place. Commercial Applications and Other Benefits as described by awardee: The technology could revolutionize how ductwork in existing homes and other structures is retrofitted to reduce leakage and improve indoor air quality. If one percent of the nationÂ¿s existing housing stock adopted this technique, it would result in savings of 5.5 billion watt-hours of electricity per year.
