Venting a Bathroom Fan in Tenafly, NJ
The correct way to vent a bathroom fan through an attic is to terminate the vent either to the roof or to the gable wall. Either way, the vent will have to go directly to the outside, and installed with a vent hood cover. In this Tenafly house, the owner installed a radon fan instead and terminated it directly into the attic. Doing so allows moist air, potentially causing mold buildup.
