Insulation in basement

Proper insulation and technique for insulating a basement?

11 month home with a full basement with 2x10-16 O.C. No heat source other than radiation off the boiler. Is it OK to install a paper faced insulation with the paper facing UP toward the kitchen BUT have a 2"-3" gap between the subfloor and the paper? or should it be tight to the floor, or should this insulation be unfaced plain and simple?




The insulation vapor retarder is correct (towards the living area), but the insulation blanket itself would be better if it’s pushed up against the sub floor.
