Exhaust fan venting in powder room
Posted by DH on February 08, 19101 at 22:32:31:
Is there a problem with venting a powder room exhaust fan into the airspace in the roof joists, above the insulation? It would essentially vent thru the ridge vent. I know you wouldn't want to do this in a bath where you had a shower, which would create a lot of moisture in the air. Powder room only has a toilet and a lavatory, so fan will just be there to remove odors. Would venting in this manner cause excees condensation just from the inside warmer air being vented into the colder outside air that would be above the insulation?
