Q:

Is cloth a good insulator?

A:

Quick Answer

Cloth can be a great choice for green and chemical-free insulation in the home. Using cloth as an insulator keeps fabric scraps out of the landfill and minimizes exposure to harmful chemicals common in modern insulation.

Full Answer

Conventional fiberglass insulation has been shown to contain formaldehyde, a chemical commonly associated with increased cancer risk. Cotton insulation will not cause skin irritation or respiratory problems for those coming in contact with the material. Like fiberglass insulation, cotton insulation may be rolled into batts for easy installation.

When insulating a pre-existing structure against drafts from old windows and doors, cloth is a cheap and effective insulator. An old blanket can easily be turned into a curtain or tacked over a drafty window to minimize airflow from outside. Thicker fabrics will be more effective, while thinner fabrics will allow more natural light into the home.

  • Q:

    Why is aluminum foil a good insulator?

    A:

    According to HowStuffWorks, aluminum foil is a good insulator because it prevents the radiation of heat by reflecting it back at the source. Since aluminum foil reflects the emission of heat, it tends to be a better insulator than other materials that just slow down the flow of heat from one area to another.

    What are good uses of atomic energy?

    A:

    Atomic energy, also referred to as nuclear energy, is used to generate electricity, and has applications in the fields of agriculture, medicine, research and industry, too. Atomic energy contains highly active radioisotopes, which are various forms of atoms comprised of the same chemical elements. These isotopes share many chemical properties, but have different volumes of relative atomic masses, which makes them suitable for different chemical, electrical, engineering and industrial practices.

    Why is air a good insulator?

    A:

    Air is a good insulator because its molecules are very far apart. This makes it difficult to transfer heat, according to Dr. Ken Mellendorf, a physics professor at Illinois Central College.

  • Q:

    Why are metals such good conductors of heat?

    A:

    Metals conduct heat well for two reasons: metal ions pack very closely together in their molecular lattice, and electrons drifting through the metal carry kinetic energy around the lattice. The result is a quick elevation in particle motion that is expressed through heat energy. This conductivity is one reason why one rarely sees metal playground equipment anymore — although the slides go a lot faster than plastic ones, sitting on a slide on a hot summer afternoon is often quite painful.
