Reply to comment by mcdiego in How to Insulate Bathroom Exhaust in Attic by mcdiego

Anyway to get it to exhaust to outside should help. If you have an eaves vent then go for that because that's hot air out and would help push bath air out. A soffit draws air in and might pull humidity back in.

Okay nice. I’m going try for one of the eaves vents.

Any thoughts on how I should secure the hose to the eaves vent? Or could I get away with just resting it on there? Mainly thinking about a strong wind gust or something could move it off.

Really appreciate your help.

Buy one of those plastic discharge adapters and just screw it against the vent. You should have 2x4s around the eaves vent and should be able to just fasten it on an edge. Clamp or zip tie hose in place. Or if money is that tight you can always just screw the hose itself to the wood. Use washer to give more holding strength. A washer can be any flat item, piece of wood even.

If you vent out the soffit, consider using rigid ducting instead of a flexible hose. It's harder for a fan to push air through a flexible duct, so the fan will work better. It also allows you to put a small drop from the bathroom fan to the soffit exhaust vent. Doing so will allow any condensation that forms to drip out the soffit exhaust vent.
