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
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.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 >
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 >
Many metals, like silver, copper, gold and aluminum, are good thermal conductors. Thermal conductors are materials that heat passes through easily. Conduction, or the transfer of heat, can take place within a single material or between two objects.Full Answer >
