Find some closed cell polyethylene that is quite thin and some very light
aluminium foil and you could make many layers.
How about aluminized Mylar?
If the many-reflective-layers idea really works, I'd expect somebody to sell
foam built that way. Why don't they?
Maybe demand is small for such a product?
They do make thin metal/fabric multi layer stuff (for things like
exhaust systems) where the fabric is something moderately refractory
(fiberglass? ceramic wool?)
And, for spacecraft (a very small volume application) look up
"multilayer insulation" or MLI.
