Thanks for the response AC
I'm starting a restoration on an old farmhouse in Maine and I've stumbled across this site and from what I've read so far I expect to receive some good advice here.

The farmhouse was built by ancestors in the 1850s. It's a 3 chimney 1000 sq ft box. No insulation whatsoever. I've been in the crawl space and can see the floor timbers are 2' OC.

I asked the above question because I'm planning to insulate the floor as I described. I was planning on using 2 overlapping layers. I'm surprised to hear that a thermal current loop would form. Do you think it is a significant loss? Can it be mitigated?
