Since I'm now supposed to have extreme confidence in my plumbing ability, my son and I installed the 3/4" subfloor after installing some 100 square feet of R30 batting in the crawl space. I'm closing up the floor joists with 1/2" insulating foam (R3). I'm wishing I'd kept some of those wooden laths from the plaster demolition -- they'd make great slats for keeping the screw heads from breaking through the insulation when I attach them to the floor joists.
The walls are all getting R13. The original plan was to install Icynene insulation. I guess I didn't look far enough because there's an installer "just down the street".
