Flexible ducting will reduce the amount of air that flows through it alot. It's like using smooth ducting that is much smaller in size.

And it gets worse the longer it the run of it is.

I would limit the use of the flexible stuff to only those places where you don't have any other choice.


My next thought is to run the exhaust through an outside wall somewhere be it the roof or an exterior wall in the attic. You don't want particulates settling on the inside of the attic.


Also keep the inlet for your makeup air at least 10 feet from the exhaust and run that from outside air too. Any suction you put on the air in the attic is most likely to pull air conditioned / heated air from your home and push it out your exhaust wasting money unless you leave a window open in the attic and that would allow rain in.
