There is a closed-cell foam, aluminum foil clad on one or both sides that is used as HVAC ductwork - they score it with a knife, and fold it to size - that should withstand the temperatures you are contemplating, for a long time. I have seen some approximately 1/2 to 5/8 inch, and the quantities you need should be available free from your local HVAC shop.
