It being summer here, I’ve stripped the inside walls and insulation. It was built in the 60s and had terrible insulation. I did have to wear a respirator because that era of gyproc used asbestos and mine tested positive. But now I’m furring out the walls on the inside with 2X material to get an R20-24, and I’ll probably add a reflective layer for added heat retention/reflection. I also have to re-do the siding, so I might add a 2" closed-cell layer under that for another R8. I’d like to have it competely passive, with a greenhouse on one side to gather winter heat and circulate. Winter here is pretty much 8 months so I have an uphill battle there.
