Basement rigid insulation
Hello GBA community,
I’m planning to finish my basement and encapsulate my crawlspace. I intend to use 3″ polyiso, but there are a couple of spots that I was wondering if the insulation really is needed. Picture attached shows the layout and the specific three question areas:
Red: a wall that juts out into the basement like a narrow peninsula.
Orange: a mechanical space where the existing plumbing/water treatment equipment is all strapped to the wall
Yellow: inside the crawlspace on the shared wall with the basement
Thank you for your thoughts!
