Who fixed it............Frank Spencer?
If I were you I'd just start by replacing the current ducting with some insulated ducting - it's cheap, still flexible so easy drop-in replacement (it's a bit more self-supporting so actually a bit easier!) and tends to have a smoother bore because it can maintain its stretched out shape better so performs better. It tends to have around 25mm of insulation, which is fairly typical for ducting in unheated spaces, and given its strength can be easily insulated by throwing more loft insulation over the top without crushing it.
Thats a good practical solution. Thanks.
So just to confirm (unless its not already apparent, Im a complete DIY novice!!) this is what I need to get: https://www.screwfix.com/p/manrose-...55281954508&ds_rl=1249404&gclsrc=ds&gclsrc=ds
I presume theyre all a standard size. How do I fit/secure it either end? (to the fan and to the roof exit).
Perhaps - as been suggested in this thread - Id be better off hanging the exit end in the gap at the eaves rather than attaching it to the exit vent in the roof?
Just hold fire on ordering anything - I see the one I linked to is 'acoustic' which means it has small holes on the inner skin which you probably don't want if there's any risk of even a small amount of condensation forming. I'll keep searching but it looks like there's quite a shortage at the moment (maybe that's why the Screwfix stuff is so expensive).
