Like Floyd said, or batts with paper backing stapled to the joists, although the second approach is less desirable because the paper backing can get damp and fail, allowing the insulation to fall out.
With 12” joists, we got somewhere in the area of R-30 to R-40 of insulation in the floors out of that. I’m not sure what thickness batts they used, I would have to go back and look at the work order. They also insulated all exposed pipes as well, since the insulation would reduce heat transmission from the house and allow the air temperature in the crawl to be closer to ambient, potentially allowing any exposed (copper) pipes to freeze. I’m still stunned that the place never had insulation in the floor/crawl. It had to be a frickin’ icebox in the wintertime, or the PO ran the wood stove full bore 24/7, which would have been pretty expensive with the amount of wood it consumes. -D > On Mar 6, 2022, at 2:08 PM, Kaleb Striplin via Mercedes > <mercedes@okiebenz.com> wrote: > > How do you install insulation in the crawl space?
