Nice drawing, what did you use to make it?

One layer goes between the joists, with a four inch space below the floor. A second layer goes across the bottom of the joists. The more air-tight it is, the better. I sealed mine with caulk and an aluminum tape they use for furnace ducts. NOT cloth duct tape, the glue dries out and it peels away. The insulation comes in 24 and 48 inch widths. I found it easy to staple in place and I liked that I stayed clean.
