Insulation

Hello everyone. I currently have my floors removed to the joists and just had my crawlspace encapsulated/sealed with a 20mil liner (CleanSpace System). I'm going to do a radiant floor on top of the subfloor. What should I do insulation wise in the crawlspace area or should I just put it between the joists, or both? Thanks!

What are your outdoor winter temps and ground temps or freeze depth like?0

I live in Central Indiana just about 10 miles North of Noblesville so it can get quite cold. I have no idea about freeze depth0

I would insulate the bays with the thickest fiberglass batts I could fit (R-30 for 10" joists, R-38 for 12" joists.) Covering the exposed joists would require something like rigid fiberglass to avoid dewpoint issues.0

Thanks for the response! And put the vapor barrier portion toward the floor correct? Something like this?
