Extracting the....

[NozSpark]

.....damp smelly air from a shower room..

Got a job to do and customer is fitting a false ceiling below a vaulted roof (with roof lights). As the shower room is totally internal they are putting some glazing in the ceiling for natural light (this doesn't affect my work) and it will require extraction above the shower cubicle.

I was thinking of a SELV extractor fan in the ceiling (above will be inaccesible after work) with a duct upto and then through the roof light which they will get altered to suit..

and now to my question,, is there a window kit available for this situation? bearing in mind that the roof light is at approx 45deg so it will need to have a cowl.

Last time I needed to vent a shower extractor through a roof, I got the customer to first get a roofer in to fit a vented ridge tile to connect the shower fan to.

Is there room for a separate duct out and cowl?

 

[NozSpark]

Normally that's what I'd do, but I'd rather not disturb this rather old roof..

Only real problem is that there are in fact 2 shower rooms (back to back) under the same vaulted roof / false ceiling... so there are 2 extractors in reality requiring 2 vents (or I suppose I could use a Y connector and butterfly backdraft shutters)

Is there any access in false ceiling?

 

[NozSpark]

I doubt that there will be!

If you are going for low voltage I would go for xpelair they seem to work quite well fitted a couple and quite impressed having fitted manrose ones in past and they certainly don't seem to work. Tlc do them but you may be able to get them a bit cheaper.

It's not the fan that I've got the problem with... it's the window vent!

Sorry misread first part not sure on this are you trying to vent through glass?

 

[Andy™]

is there only one pane of glass to go through? you could get a fan fitted into the glass?

 

[NozSpark]

Yes, through the glass as they don't really want the roof messing with if at all possible..

The window is at about a 45deg angle so it will need some sort of cowl

Won't the rain come through?

That's why I'm asking you good folk to see if anyone else has had this problem before and found a solution to it..

BTW the fan cannot go in the roof space or in the window it's self

Sorry not something I have done.

possibly. i have fitted a fan into a window a few weeks ago, but it was not on an angle/roof. but id imagine there is something available? maybe an outlet with a cover, similar to how the roof vent would be?

I think a tumble drier vent may work, Only pic i can find is here http://www.gwsupplies.co.uk/electrical/c/1125/duct+(cookertumble+dryer)+kits.htm

That sounds like just the thing,, with a silicon seal.... just how to connect the 4" duct to it.
