I just volunteered to help with a project, insulating a floor. I haven't actually seen it yet, but I understand it is a typical joist construction over a crawl space. A family room add on that wasn't insulated when it was built. I've never done this before, but I understand we should have a good vapor barrier down on the ground. It seems to me that we should use unfaced insulation, and not have a vapor barrier under the insulation. Is that correct? Any ideas on the easiest way to hold the insulation in place?
