Bathroom Moisture Fans

Its not always black and white.

In the earlier years of building all bathroom moisture fans were either exhausted to the overhang or directly inside the attic. This was usually very effective because there was enough air movement where the moisture was removed through the venting system of the attic. Now days with tighter insulation and some attics having an issue with the overhangs being blocked off with insulation this becomes a problem where the fans discharging location needs to vent directly outside.
