Question

Is metal a good heat shield?​

Answer 1

• If used in a certain way, metal can indeed act as a good heat shield.

• At the same time, if metal is used in a different way, it can act as a good heat sink, which is the opposite of a heat shield.

Answer 2

For this reason, metals are excellent shields to thermal radiation. If the main way that heat is being transported in a particular system is through thermal radiation, then metals are excellent heat shields. ... Therefore, if a metal is in direct contact with a hot object, it will quickly carry heat away from the object.
