Finishing off Wall under Window

[tikroh]

What would be the best way to finish off this low wall under my window?

I was thinking of Plasterboarding the front wall itself, but what can I do with the top?

Can I just put a uPVC Window ledge on?

Thanks

Strip of PIR foam first, then plasterboard or window ledge.

Are there two windows, as there is a gap on the first pic, but not the second one?

No, just an illusion!

Exact same location just different angles. It's 1 Window.

PIR to Window and across Wood right? Not sit it in cavity?

Thanks

Fit a (cut down) window board.

Is a window board an internal window sill? Or a specific item?

Just Googled it and they seem to be MDF. With PIR on top taped that should still be fine right?

Wickes do a uPVC Window Facia board. That similar?

I can't foresee much moisture coming up or condensation getting in either.

Thanks
