The smart and inexpensive way to insulate joist bays is to use extruded polystyrene (XPS) foam insulation panels cut to size to fit inside the bay and “glued” in with expanding foam. When the foam expands, trim away the excess and cover it with a piece of drywall tape.
If you don’t have access to XPS foam, you can make your own by cutting a 1-1/4″ x 2-3/8″ piece of foam and gluing it to the bottom of a 2×4 or 3×6 panel. You’ll need to cut a hole in the center of the panel so that it can be screwed into place.
If you have a drill press, use that to drill the hole and then use a screwdriver to tighten it down.
