Good insulators are materials that do not allow heat to pass through them. They are also materials that either slow down or do not allow transfer of electricity through them.

The best material that serves as an insulator is glass because of its high resistivity, states Georgia State University or GSU. The photons present in glass do not have enough energy to close the gap between the valence electrons and the conduction band.

Insulating materials reduce the heat flow in a home, which allows the air a cooling or heating system produces to stay inside, and protect a home from external temperatures. Insulating materials are given R-values based on their insulating effectiveness; the higher the R-value, the more effective th

To install insulation, you must first determine the exact area to be insulated by taking accurate measurements of the walls. There are several choices when it comes to types of insulation, so choosing the right one is another important first step to achieving the ultimate insulation barrier for any

The insulation requirements for homes vary based on the location of the home, but in the United States, most homes should have attic insulation equal to values between R-30 and R-60. Local building codes determine the minimum insulation value but additional insulation makes the home more efficient.

Insulation is installed in homes or businesses to reduce noise and help maintain desired temperatures inside. Insulation reduces the heat transfer between the inside of a building and the outside.

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.

Insulate existing walls by locating the wall studs, drilling a hole into the bottom of the wall, checking the cavity for obstructions, blowing insulation into the cavity, and repeating between each set of studs. Patch the holes once the job is complete.

Wood works well as an insulator because of all the empty space that it contains. Insulators contain heat and other forms of energy rather than transferring them to another object. Conductors, on the other hand, transfer energy easily; many metals are among the very best substances for energy transfe

Glass is a good electrical insulator because the electrons in the glass are tightly bound to the atoms and do not transfer easily, thus keeping electricity from moving through the glass. Conversely, good electrical conductors contain electrons that move freely.
