Bathroom Exhaust Fan Duct Location
Hello GBA members-
I would like your advice on a new bathroom fan, interior ducting, exterior vent housing and location of this.
I have a hipped roof with eaves and soffits. Currently an old fan is vented into one of the soffits but I don’t detect any mold issues as best as I can visualize.
I will be replacing the tile roof with a metal one and will insulate the attic floor space, in a cold roof fashion. BR is approx 75 ft sq/8′ ceiling.
Any advice on a quality exhaust fan? I have a few links to products that seem to have good reviews.
This company seems to have good products. I like the durable seal and have read that someone also uses butyl tape for extra seals around the screws:
any recommendations on the duct from the bathroom to the exterior? Smooth aluminum (insulated or not?) ducting or insulated flexible?
I could run the duct horizontally/parallel/between the floor joists and then 90 degrees vertically through the roof. This would be approx. 4.5′ rise to the interior of the decking. This penetration would be about 3′ from the hip ridge and about 8-10′ from the lower roof/gutter edge.
Would this vent location be better than venting through the soffit?
Thanks to all.
