Hi,

How does one install an exhast fan when the joists run parallel to the
outside wall. My prospective contractor recommends drilling holes in
the joists. This is a larger bathroom so I need a larger fan so I am
going to have 6" holes in my joints. Isn't that effectively cutting
them in half? What could be an alternative solution?


You should be able to find larger CFM fans that only use 4" duct. I don't
think gouging out a good portion of your joists is a good idea. Another
possibility is to build a small soffit to accommodate the duct.
