actually the insulator is the dead air in the pores
a better insulator is vacuum (only radiation)
air has conduction convection and radiation
air is easier to handle near sea level

What MATERIALS were used by the first people in cold countries?
The first materials used were items that could protect the community from the harsh elements. Those materials were animal pelts, wood for fires, and probably animal fat used as fuel to keep the fires burning.Ê
Are gases thermal insulators?
Yes. Gases have low thermal conductivity, so if you keep convection low (bulk movement of the gas) they are good thermal insulators. Refractive bricks used in kilns (high temperature ovens) made of silica and some other low conductivity materials are made intentionally porous.
What are some heat insulators?
Some heat insulators are fiberglass, polyurethane foam, and polystyrene. Two other thermal insulators used as insulating materials in building construction are mineral wool and cellular glass.
What is the opposite of thermal insulators?
The opposite would be thermal conductors, as are used on cooling radiators.
What name is used for materials which do not let heat past them?
Insulators
What are some ways rubber and plastic are used as electrical and thermal insulators?
Plastic and rubber are used to cover electrical cords on most commonly used household electrical devices. You can also find rubber covers under the hood of your car that are used as thermal insulators.

What are good thermal insulators in buildings?
Ionic compounds are good thermal insulators. Magnesium carbonate, an ionic compound, is sometimes used. Ionic compounds have extremely high melting points and therefore, if they were heated they would not melt.
What are some materials used to test a simple circuit for conductors and insulators?
Battery,Tester
How are thermal insulators used to control the transfer of thermal energy?
Manufactures usually make building insulation from a fluffy material, such as fiberglass,that contains pockets of trapped air.
What are the raw materials used in thermal power plants?
coal is used as a raw material in thermal power stations
Different types of materials used in industry give examples?
Some of the materials that are used in industry are textiles, plastic and rubber insulators and combustibles. Some combustible materials used in industry include coal and firewood.
What materials are used to make a thermal curtain liner?
wood?
If you were making a tool used to handle live electrical wires which class of materials would you most likely use?
These materials must be insulators.
