I'm not sure if this is the best place to ask this question, but regarding bathroom exhaust fans, I understand I they are best to duct:
1) Preferably to the gable (with the pipe angled slightly downward outside?)
2) Short duct runs (insulated duct?)
However, since I have the 2 bathrooms upstairs in the center of the typical 4-bedroom "New Jersey 1970s colonial", I can only do one of the above. The question is, which option is better?
Is it better to "short-run" pipe the bath exhaust through the "roof"? or is it better to "long-run" it to a "gable vent" on the side of the house?
Here is a picture: The two bathrooms are where you see the two inner upstairs windows: http://tinyurl.com/k8te647
I seem to be getting conflicting information from different contractors...I'd really like to know what you guys think. Thanks so much!
