extractor fan in a warm roof

[hoofsmit]

hi,
new to this site,
i've read a lot of topics on the forums re extractors but none seem to have come up with the answer to my problem?

i have a sloping warm roof in my bathroom
joists are 150mm with multi foil insulation over with 70mm celotex between, my ceiling is 3.1m high sloping to 2.1m at eaves

the shower is under the high point thus i need to extract at the highest point and send the duct down gradient to vent at the soffits ,,, can i do this ?

also finding an axial fan with 90 degree duct to fit inbetween 150mm joist height is not happening..... other option is to wall vent

your idea's would be really appreciated.. sorry so long winded

regards

How about through the roof with a vent tile ?

thks for the quick reply
should have said .... cedar shingles with a 95mm exsposure thats 4 on top of each other so any flashed roof fitting would really kick the neighbouring courses and need a major peel and replace
thanks thou

Vaulted ceiling - in a shower room....interesting...!

I take it there is no gable then?

Flat channel ducting should do it, this is about the thinnest I have seen
