The lack of a material, e.g. a perfect vacuum, as long as radiation doesn't get involved.

Radiation becomes the dominant heat transfer mode in that case though, usually gets really small at day to day temperatures though.

It's not that small. Blackbody radiation at room temperature is 450 watts per square meter. And it only takes an extra 15C to get 100 net watts transferred per square meter.

Radiation is always involved, even at very low temperatures.
