I think I either saw or read to use either aluminium or I may have seen
some protective material..

Of the top of my head it was on a supplier's website when I was
searching for something else.

On the existing carcase, there are quite deep burn marks

You certainly wouldn't need to on any modern built-in cooker I've come
across - they are designed to sit inside a purpose-designed unit. That
being said, the cooker instructions will definitely state what
clearances, ventilation, protection etc are required, so you should
certainly consult that (and obtain one if you haven't got one) to get a
definitive answer.

The burn marks do sound worrying - shouldn't be doing that so
something's amiss somewhere.

Well at least that old cookers' gone.

So you've not seen this material I am talking about then.
