The soffit allowed us the option of venting the third bedroom bath fan out the wall instead of through the roof. Using a section of flex duct in the attic helps to quiet the exhaust and allows for an easier sweeping turn using rigid thinwall PVC for the powder room fan. Kevin used Zip tape to attach the flex duct and PVC and applied fire retardant spray foam around the fan unit in the attic, and also around the penetration through the wall and ceiling.
