Extractor fan vent tile in hanging tiles

[SJRSJR]

Hello

I need to fit an extractor fan in the side of my new dormer, which will be clad in vertical plain tiles of Sandtoft Humber (Tuscan colour). I've only been able to find one place that sells what I think I need but it isn't available.

Are they standard fit? For example, my tiles are 265 x 165mm so if I can't get an exact colour match, will any of these do the job?

Are there any other makes to search for? Thanks

Is going vertical (through the roof) not an option?

Can you mark the hole, remove tiles and cut with a grinder?

Thanks for the replies.

It's what the roofer suggested but it the wiring is already in place for side entry and the ceiling is already plastered. I also thought side entry would be better to avoid any condensation dripping back. I know you can get condensation traps but the ceiling hole would have to be bigger to put it through (unless the roofer puts it in from the outside). Maybe that's not an issue if the vent cover will go over both, but then I'd also need overflow spout which would look a bit ugly.

The tiles aren't on yet and that's what I thought, but the roofer says it's easier to put it in the roof.

piece of cake....

I'm doing one as I'm typing

 

[SJRSJR]

Thanks but I was hoping for something smaller that would blend in a bit more. It’s only a dormer and the black seal alone would be massively disproportionate to the tile size!

Interestingly, a tech department who make plastic tile vents advises against using them vertically because « it is likely that the discharge of warmer moisture laden air at the tile surface will result in water vapour passing through the gaps in the tiles above the ventilator where it is likely to condense on the tiles and other surfaces potentially causing premature decay of the construction behind the tiles, primarily the tile battens. »

Wouldn’t that happen on any pitch?

All done....

Not really.
It's the same thing.

Removing and replacing tiles on a roof is not the same as removing and replacing tiles on the vertical (tile hanging etc).

The roofer is right.

Is the dormer roof pitched and tiled?

 

[SJRSJR]

Is the dormer roof pitched and tiled?

It's a new pitched dormer roof but nothing is tiled yet (top or sides).

I found this locally which the roofer's colleague is happy with. It's Manthorpe GTV PT vent. If I'd had more time I'd probably have gone with Glidevale who will do a colour match, but they're fitting the tiles this week.

What are you messing around at? Go through the roof!

 

[SJRSJR]

Thanks Noseall but is there a reason why is going through the roof better is better? All things being equal I prefer the aesthetics of a side tile vent to having a vertical tube coming out of the roof. Obviously if there are potential problems I’d think again

That Manthorpe jobby is a roof space vent and not a TVT (tile vent terminal), which has a bulky spigot on the back and usually a cowl on the top.

 

[SJRSJR]

It does have a bulky oblong spigot adaptor which connects to extractor fan ducting. The description also says it’s suitable for mechanical ventilation but I checked with their technical support too. Some designs have cowls but not all. Am I missing something here?
