Hidden gutter detail

[BartW]

Hi,

I am planning all detailed aspects of our future building, and there are some gutter details I need to design. Obviously, one would want them as sleek as they get. We would like to conceal them efficiently where possible.

 

Could you guys have a look and comment if the below might work:

 

Side facade at junction of 30deg pitch slate tile roof with vertical rain screen facade in matching slate tile. Both Cupa Pizzaras R.

The fact that we will have the facade tiles, this would allow us to conceal up to 40mm in depth (batten on batten). The rest would need to be notched in Durisol. But what about the detail between the gutter itself and the top row of the tiles? 

 

Next one up would be the flat roof terrace. I would like to avoid having traditional hoppers (or modern ones in fact too), but I seem stuck for the exit points. Would concealed GRP linear gutter detail along the RHS elevation terminating to a (concealed again) downpipe exit point and being taken away into the downpipe hidden behind the side elevation (timber facade) be a good idea here?

 

 

 

 

 

 

Thanks 

Bart

My first reaction to seeing this..

 

...Is that heavy rain will overshoot the gutter. It will also be very important to get the details under the gutter right when its built. The facade tiles would need to be behind the drip bead shown.   In case you are wondering.. you can't hide the gutter behind the tiles.

Not fail safe so best designed out

We're planning to use the Galeco system in our build (for now at least), as ever the devil will be in the detail to get it to work as designed.

Does anyone know whether it is actually approved for use in the UK? Appropriate certification etc? Our architect couldn't find any but we're gonna give it a go anyway.

Yes, the tall angle of the roof would easily make the rain into a waterfall. There was another detail there that seemed to show a 30deg pitch, and less aggressive rain setting (or at least it's how I saw it).

 

Not sure about certification, and quite frankly, I was probably being too ignorant to consider it being a total must...

 

Another alternative is to build a boxed eaves gutter, GRP it, bring the facade in front of it, and finish off with GRP / aluminium capping.

A bit like here:

As for fibreglass gutter details then @Barney12's detail is a thing of beauty.

Hi guys,

A quick bump in case anyone might be able to offer some advice on this?
