I'm looking to install an 80 CFM Broan XB80 bathroom exhaust fan in our first floor bathroom (5' x 12'). The bathroom was built with no fan and I will have no access from above. Duct can be either 6" or 4" as well. I plan to run the duct parallel to the floor joists and out the side of the house, which is just under 14'. The duct will go 2.5' across the bathroom, then another 11' across the bedroom and out.
I'll only have access from the outside and through the hole for the fan, but I could slide the entire duct in from the outside. My issue is will the duct sag and how do I support the the duct without having to cut out the ceiling in the bedroom to install straps?
Would thin walled PVC be a good option? It could be solvent welded to nearly the entire length (no worries for condensation leaks) and slide in as a single unit. Would use a short flexible house to attach to the fan housing and should be able to get a strap in at the fan end.
What other options should I consider?
Thanks,
