Tips for Insulating This Tricky Rim Joist
Thanks for advice as always. I have an area in basement I’m not sure how to fix.
1. I attached picture, I have a makeshift beam in middle of window bay as well as a what looks like another makeshift wood post from floor to ceiling to right of window I would like to insulate wall and rim joist. I’m assuming easiest way to fix this would be foam board insulate this wall and build a 2×4 wall in front of it? Do I need a double header or extra reinforcement? What do I do on top of window? There is no cavity, so not sure how to insulate rim joist, do I make some sort of shelf from new wall to exterior wall? I guess there could also be some way to fix this without building a wall but I have no idea
