The most important place to start is the underside of the icebox top, it's just raw plywood. The opening lid has some light foam inside the fiberglass. The outside of the icebox has a couple of inches of urethane foamed in place. Our freezer unit is right under the removable lid, I made a "cap" for it from 1" foam insulation, it keeps the freezer much colder. We additionally keep some heavy industrial bubble wrap on the top of the whole compartment, that helps hugely.
