Bathroom extractor ducting run

[robbie77]

Hi

I have purchased an inline extractor fan as I was advised that these are good https://www.toolstation.com/airvent-100mm-mixed-flow-inline-extractor-fan/p70282
It will be going in a small bathroom. I will position it in the middle of the bathroom as to get above the shower there is a noggin in the way but I think it should still be OK. I will have to run the ducting along the joists. I bought some 100mm PVC ducting to attach to the in line fan that will be mounted on floor above bathroom toward the eaves so out the way.
Am I OK to just clip this to the joist with some sort of fixings or should I box it in with plywood or something?
Can anyone give me some advice on this?
Thanks

Yes, secure it to the joists do it doesn’t flap about.
these are handy

Keep duct run as short as possible
