Hi all. New here.
We just finished installing an A/C air-handler with rigid round metal ducts in our attic. The installation was done by a HVAC pro. (We are located in Southern Ontario, Canada).
Our plan is to insulate the ducts with spray foam. The question is which type/brand to use?
Each dealer/installer we talked to talked up their product and diss the competitor's.
We are most confused about VOC and other nasties released during application and the time required to vacate the house.
We are also confused about fire rating and requirement for a fire barrier.
Any suggestions, opinions, comments etc most welcomed!
