Professionals have different methods of performing duct sealing when you call on them. We’ll look at the two main methods that apply when they come to a home to fix a leaky ventilation system.
Flexible Duct Sealants
Duct sealant is a resin-based sealant that many duct repair technicians favour. It’s used in many types of construction and repair jobs for creating a flexible yet solid joint and to form airtight seals around fixtures such as windows and watertight seals around sinks and bathtubs. It adheres to almost any material, including duct board, making it useful for all types of ductwork. Sealant leaves behind a smooth surface after it dries, which means it provides little resistance to airflow inside ducts. It’s also waterproof, resists temperature extremes that affect ventilation systems, and will not cause corrosion over time to metal surfaces. Duct sealers will use a silicone gun to apply sealant to ducts.
These are the true “duct tapes” used in professional duct sealing, and some technicians prefer them to sealants because they create an actual mechanical seal and tend to have greater longevity than resin-based sealant. Most of these tapes are made from foil because its lightweight. Metallic tapes have high metal resistance and many uses aside from ducts, and have proven their durability in other industries such as aerospace, transportation, and automotive.
