Can I run a dryer vent against a basement foundation wall?
I live in Montreal, Quebec, Canada, where winters are quite cold and severe. Temperatures here can be as low as -30F in winter. I'm not sure this counts as an HVAC question, but I think this forum is the closest match I can find.
I am installing a new dryer vent in my basement and in order to save as much space as possible, I'd like to run the vertical part of my vent in between my 2x4 studs directly against the foundation wall (a run of about 8'). The walls will be insulated with fiberglass (pink) and covered with a vapor barrier and drywall.
My concern is condensation. Is condensation around the exhaust pipe a worry? Do I have to ensure that my pipe runs on the inside of the insulated walls? Or do I need to use an insulated pipe? (ie: can I take a 4" pipe and insert it into a 5" pipe and line the space in between with fiberglass?)
Thanks for any suggestions!
