tin foil is bolth, because it is a metal so electricity goes through it and it holds heat well
Electrical or thermal? Either way, it's an insulator.

A diamond is a superior conductor of thermal energy (heat). It's better at this than anything else we know of. But diamond is a poor conductor of electricity. It's actually a pretty good insulator.
A good insulator means a bad conductor. It is the opposite of good conductor.

Conductor. You're trying to move heat, not block it.
Stone is most definitely not a good thermal insulator. It changes its temperature quickly with the surrounding environment. In fact, stone is a thermal conductor and will pass heat or cold right to the adjacent materials.
Perspex is brand name for the poly (methyl methacrylate) and is not a good conductor of electricity.
