is there any material known that extreme temperatures will not bleed through?
For example:
Say you have a metal container with extremely hot liquid inside. If you try to grab it, you'll feel the heat. And if the same is filled with something frozen, it will perspire on the outside.
The same goes for plastic, glass, Steel, rubber, styrofoam, porcelain, lead, etc.
Also, I'm sure that if you make it thick enough, it may not bleed through, or not so easily, but what about a somewhat thin material, like that of a thermos or a cup?
Does such exist (no alien technology answers please).
Just a question I've been thinking about for a while.

No, there are only degrees of insulation, there is no perfect insulator.
The closest is a vacuum, but you will have heat transfer via radiation, and via any mechanical supports.
If you went to outer space, near pluto, and had a hot object a mile away from a cold object, there will still be a miniscule amount of heat transferred from the hot object to the cold object. With increasing distance that amount will decline, approaching zero, but never quite attaining it.

Silica aerogel has a thermal conductivity as low as 0.004 Watts/meter-Kelvin and holds the Guiness record for best thermal insulator (along with 12 others). Read the page at the link to see how it's made.
