Just a thought, would insulation foil do it, like the stuff they put behind
radiators?

It is liable to get rather warm in there though, doesn't this stuff have

Don't want melted plastic oozing out of the bottom, or worse, black smoke
coming out of the top.

Nowhere near enough insulation, and the core gets way to hot for such stuff.
