In this episode of the Structure Talk podcast, Reuben Saltzman and Tessa Murray discuss dryer ducts and the importance of fire safety. They cover the materials and thickness required for dryer ducts, the size and location of vent terminals, and the maximum allowable length of dryer ducts. They also share personal anecdotes and recommendations for maintaining dryer ducts. The conversation emphasizes proper installation and maintenance to prevent lint accumulation and potential fire hazards. They discuss various aspects of dryer ducts, including size, length, terminals, and materials. They explain that the maximum length for a dryer duct is 35 feet, but manufacturers often allow for longer lengths. They also discuss the importance of proper installation, including using UL-listed foil tape or mastic to secure the ducts. They caution against using indoor dryer vent kits and plastic corrugated vents, as they can pose fire hazards. Reuben recommends having the dryer duct professionally cleaned annually for longer runs.
