Ok so I've been looking at the Velux sizing and I'm a little lost as I can't really tell if the sizes quoted are related to the finished measurements or the spacing to which they fit.
Joists are spaced at 400mm centres so I was looking at the Mk06 (780x1180mm) and planned to use the Velux flashing kit, but is this window the right size or do I need a smaller one?
Thanks and sorry if I'm asking what seems like a silly question, but I'd rather be sure and would like to avoid respacing joists if possible.
