How to air seal bathroom exhaust fan?
I was up in the attic checking things out before the winter and noticed that our bathroom exhaust fan was installed without a vapor barrier. The venting looks correct in that it is insulated. I would like to add a barrier before the winter but how should I go about doing so? I really don't want to remove the fan to install the barrier.
I was thinking I can buy a vapor barrier boot the size of the fan or those available for potlights, and cut it to fit around the fan housing and tuck tape the crap out of it to the drywall and adjacent joist. Does this sound like a good idea?
