I'd like to put something like a cupboard a little lower than is usual
above a hob.

Maybe 400mm instead of 650mm (which I think might be the usual
recommended minimum).

Seems to me that if I put a stainless steel sheet (which doesn't
conduct heat as well as most other metals) on the underside of the
cabinet, with a thin layer of some kind of insulation above it,
that would protect the cupboard while also being easy to clean.

But what kind of insulation? I suppose it should be something which
would tolerate at least 100C, maybe 200C if thinking about frying
temperatures.

(Not asbestos, obviously!)
