an ideal thermal insulator does not conduct heat at all,so it keeps heat out!
A thermal insulator is totally incapable of answering this question
Rubber can not only keep heat OUT, it can also keep heat IN. It only depends on which side of it is initially at higher temperature. This property of rubber is the main reason that it is often used as a thermal insulator.
Insulator help keep something warm by the thermal energy is transferred throught collisions between molecules,and air molecules are far apart.
There is no "material" that does not allow a powerful enough current to conduct through it. However, a vacuum (which contains absolutely nothing, and is not technically a material) will never conduct a current, no matter the power.
It is a tautology - while a thermal blanket may keep you warm, it is not doing so by thermal warming it is doing so by thermal insulation. Thermal means "relating to heat". Warming means "increased heat"

The newspaper is a thermal insulator - it will take heat longer to pass through the newspaper, than to pass through air. The newspaper - or any other thermal insulator - won't keep an object hot or cold indefinitely, however.The newspaper is a thermal insulator - it will take heat longer to pass through the newspaper, than to pass through air.

Styrofoam is a better insulator of heat than plastic. The plastic allows the heat in and out and the cold in and out. The Styrofoam helps keep the heat in.
because it can keep heat in because it is thick and good for insulation

Aluminum foil is a better heat insulator than newspaper. Aluminum foil reflects thermal energy, while newspaper absorbs and conducts heat. Therefore, aluminum foil will help keep heat in or out more effectively.
It creates a shield of air to keep the heat in and surrounding cool air out.
A woolen blanket is a good thermal insulator. Actually, air is among the very best of thermal insulator, and the wool fibre /fibreglass fibres, macerated paper, porous foam) serves to keep the air from moving and thus losing heat. Heat could be lost by radiation, conduction, and convection (a special case of conduction and convection combined.). Not of great importance in a blanket, but of importance in clothing is the fact that wool does not absorb water easily.
