Thanks for the input- pretty much what I was thinking. The "handyman" who did the job originally just kind of rested the 4" pipe next to the gable, which meant nearly everything blew right into the attic. I did the job you see in the picture to temporize until I get someone to finish the job...
My bathroom exhaust duct is positioned directly flush with the screen of my gable vent in the center. Reading this thread I am thinking about insulating the ducting.
But is it okay for the duct to be in this location?
Thanks
