Extension roof advice please

[alphatiger1]

Hi experts! I got planning for this kitchen extension design with 45 degree double glazed windows but now just trying to figure out how I can ensure the rain will all fall into the gutttering and not cause leaks(see in red)?

Should the glass be framed or not where it meets the gutter? surely it needs to be framed as otherwise double glazed panels just have black duct tape or aluminium tape which isn't a long term solution. Please can you advise?

The solution needs to meet building regs.

Thank you in advance.

You would use a glazing system designed to be used in a roof at such an angle.
