Once repaired, I used Thermo-Guard FR There is a reflective layer and some kind of insulating padding (air gap). There have been no signs of further damage several hundred hours later. In my unqualified opinion, I beleive that a reflective only shield would work fine. But I have no experience to bear that out.
