I'm adding a bathroom exhaust fan, which is being mounted in the ceiling of the bathroom (in the attic) and venting out through a vent in the wall.
right now, there is a vapour barrier (paper) between the insulation in the attic and the drywall. I will have to break this of course to mount the fan housing, but my question is, what do I do after? Should I put a vapour barrier around the exhaust fan and seal it to the paper?
I was also going to put insulation back over top of the exhaust fan - is that correct to do, or anything to watch out for? The vent pipe I have is a 4" insulated duct that will go to an outside vent (which I just installed this weekend).
