What Types of Ducts Can be Sealed?
Aeroseal is capable of sealing all types of ductwork, however the sealing rate varies with the type of ductwork. Sheetmetal ductwork seals most quickly, and internally lined ductwork seals most slowly. Aeroseal currently does not recommend sealing duct systems that are internally lined over most of their length, as the long injection times make the process very slow, and create excessive deposition of sealant material on the internal surfaces of the lining.
