Flipping a vertical plank home

[Jon Behlke]

Has anyone here done a flip of a house that utilized vertical plank construction?  This is rather overwhelming as our first flip. We're trying to change the size of one window and put in windows in two new places, but don't want to compromise the structural integrity of the home.  

Anybody have any tips or tricks to installing windows in a vertical plank house? Additionally, anyone have any success trying to insulate these things? Seeing as the walls are about 7 inches thick of 4 different layers of wood, is there much need to insulate? Bear in mind we're in Pennsylvania at the base of the Appalachians, so it does get pretty cold here.
