How would you frame / insulate these portholes.

I currently live on and am restoring an old dutch barge. I started with no idea what I'm doing and am slowly working my way up to lvl 1 boat restorer. The current job is insulating. I need to cover up all bare metal with insulation (I am using expanded phenolic foam board) but I also need to make sure I have sufficient wooden framing to attach walls to (it will be tongue and groove). The problem I am currently having is to the neatest way to insulate around some portholes and also insulate and neatly frame the triangular metal ribs. I'd like to leave the nice shiny brass visible but have everything else covered up neatly.
