Your best bet would be to ask the manufacturer all of these questions; they're the only ones that can safely give you answers. Covering up the outside of the fan with foil tape would surely stop any air leaks... but this might also void the UL listing. Yes, soffits should always be insulated. The Minnesota Department of Commerce has an excellent handout with instructions on how to seal up soffits - see page four of this document <a href="http://www.structuretech1.com/AtticBypasses.pdf" rel="nofollow">http://www.structuretech1.com/AtticBypasses.pdf </a> Are you asking how to make sure the fan is airtight, and doesn’t leak air in to the attic area?

I have a bathroom fan/heater. What do I use to seal it and can I cover this unit with fiberglass blown insulation? Also a drop down sophet do you recomend insulation in it (not covering vents ofcourse). And how do you seal the sophet? My question to you is. I have a bathroom fan/heater.
