Examples of heat insulators

All materials have the ability to insulate heat , only, in some, their constituent components offer such resistance that they are ideal to prevent a certain intensity of heat from being transmitted or propagated.

Heat is a form of energy that passes through materials, which is why there are others (insulators) that prevent this spread.

Classification of heat insulating materials

Insulators can be classified according to the material from which they are made and the presentation formats.

In all cases they are characterized by their low thermal conductivity and are useful in construction, at home and in industry.

20 Examples of heat insulators

According to the type of material they are known as:

  1. Fibrous . They serve as fillers or covers since they are composed of filaments with high porosity. They can isolate from 200 degrees to 1,700 degrees.
  2. Cell phones . These are cell-type materials, special for boards.
  3. Granular . They are insulators made up of thousands of tiny agglomerated particles.
  4. Expanded polystyrene. It is used in the construction sector, in containers and packaging. It is very hygienic and resistant to humidity, aging and mechanical pressure.
  5. Extruded polystyrene. It is a very light insulator and improves energy efficiency in homes. It is very resistant to fire and water.
  6. It is a polymer that has countless applications at home, in industry. It is resistant to corrosion and chemicals.
  7. Reflective scrolls. Excellent insulator for enclosures and rehabilitation of works. They are generally composed of layers of aluminum or polyethylene foam.
  8. Mineral wool . High insulating and biosoluble capacity.
  9. Glass wool. It is a very efficient thermal insulator, it also serves to isolate sound. It can keep internal spaces heated.
  10. It has an internal alveolar structure, it is highly resistant to water, high temperatures and its production is sustainable over time.
  11. It comes from a plant and is considered one of the best thermal insulators.
  12. It has a high resistance to fire, it is newspaper to which boron salts are added. Widely used in the construction industry .
  13. Sheep wool. For centuries it has been used as a thermal insulator to protect the body from ambient temperatures. It has low conductivity and specific heat.
  14. It is of ceramic origin with a very porous and air-filled internal structure, which gives it properties to isolate heat.
  15. It is a heat insulator par excellence. It is widely used to coat pipes, prevent condensation , energy saving and others.
  16. Ceramics. It has low conductivity thanks to ionic-covalent bonds. If it is moistened with water or fuel, it restores its thermal properties after drying.
  17. It is a derivative that comes from the mixture of rubber with sulfur. It is one of the first polymers discovered.
  18. It is a volcanic glass and it expands greatly when heated, with this action the water evaporates and expands, achieving a great insulating capacity.
  19. It is a type of clay with low thermal conductivity. At high temperatures it has fire retardant qualities.
  20. Coconut fiber, cotton, hemp, straw. These are natural fibers with insulating properties suitable for the construction and production of panels or coatings.
