So I tried insulating the aluminum channels. That was a failure. The foam would only expand ~6" either side of the hole, no matter how much you tired to pump in. Im not going to put a 15/64 hole very foot.... Looks like they will remain uninsulated unless someone has a genius idea.
Thoughts? I am trying to avoid cold bridging.
You can see the foam puking out of the holes in a few spots here. That stuff was not cheap.
Got the ceiling channels filled at least.
Box of goodies is growing
Battery interconnect cables. Check, CL score.
Got an on demand hot water tank on Ebay, killer price, should be a nice unit, 60K btu's.
