PVC or ABS plastic piping is often used on high-efficiency heating and water heating systems as vent piping for the exhaust gases, since the exhaust temperatures are relatively low.
Yes, PVC ducts can be used for bathroom exhaust fan as long as the duct’s fittings are adequately glued, the probability of leakage of water formed in the duct is low. However, many people may not consider PVC as an ideal venting method because since the duct needs to run to the attic, it needs to be insulated.
For starters, PVC is rust and corrosion-resistant. This makes it a great choice if the line needs to go under the house or is in a business where it might be exposed to gases or exhaust.
You simply need duct fittings and either regular PVC or CPVC pipes. There isn’t anything such as “HVAC PVC pipe” or duct-specific PVC, like there is with fittings, because the regular PVC pipes are already treated so that they can be used as an insulator.

Is foam core PVC good?
The foam core slightly alters some of the properties of the PVC foam core pipe in comparison to solid PVC pipe. The foam core pipe is less rigid, which means it lasts up to 10 years longer than solid pipe before it needs to be replaced. The core insulates sound, which can dampen unwanted noise within a building.
