Window detail?

[Alan Ambrose]

This is from a planning application I just saw - anyone know how this 'standard window / roof light' thing works?

Huh, interesting - another school day for me

 

Anyone have any practical experience with these? I see the roof light opens upwards as usual and the window opens inwards. Oddly this set-up is not really highlighted on Velux's own web site.

 

Is the joining trim thingy thermally efficient?

 

 

FYI on Velux's web site, I see there's also these somewhat odd roof terrace options:

I have actually seen these balcony versions installed:

They view they provide is in theory quite an advantage particularly for rooms in the roof but they introduce unfortunate complexities when it comes to gutters/downpipes. Either you take your gutter across the window, or for every additional roof light with vertical element you must also add a downpipe. Wonder how they’re handling that in your example?

Yeah I see - particularly the back view will need 5 downpipes.
