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.Know More
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.Learn More
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.Full Answer >
Metals are good conductors of electricity because their atoms contain at least one free electron. They are also considered excellent heat conductors, because the metal ions in the lattice are closely packed together, and the delocalized electrons can bring kinetic energy through the lattice.Full Answer >
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.Full Answer >
Copper conducts heat well because its atoms contain only one free valence electrons in the outer shell. Elements with a low number of valence electrons transfer heat the best, and copper has only one.Full Answer >
