Does bathroom exhaust fan piping need to be insulated?
I am building a two story home (mixed-humid climate), and will be venting the bathrooms to the outside. The upstairs vent piping will run in the attic.
Is there any particular type of piping to be used through the attic (metal ductwork, PVC, etc.)? Any typed of insulation to go on or around the vent piping? And is it ok to have the vents discharge in the soffits?
Thanks for any advice.
