tight after the insulation is put in
bigg_dog is correct, except that the insulation should be in full contact with the subfloorBut consider this option - insulating the crawl space wallsIt can be less expensive and more energy efficient, but there will be local considerations as wellWithout a lot more information, I could not tell you if it is your best optionBut it is worth researching further.
