Implemented Double Wall vs Cavity Insulation, thank you so much. Resolving this one, but if theres more to add/discuss/etc the Investigation TODO topic is still open.

this was on your investigation TODO, I set up this test which should answer the question. Same inner space on each, the double-walls building was slightly warmer than the air gap. climate was negative temps, and I allowed the air-gap space time to stabilize.
