insulative

Prevents thermal transfer

Insulative describes something that prevents or resists the transfer of heat, electricity, or sound.

Materials with insulative properties—foam, rubber, fiberglass—block energy flow: The insulative layer keeps the house warm in winter.

The word functions as the adjectival form of insulate, though insulating is more common in everyday speech.
