Why do Insulators prevent Heat Flow?

The particles that make up these materials have strong chemical bonds that keeps them from constantly moving around and transferring energy from one particle to another.

Good Insulators:

Wool, Fleece, Fiber, Wood, Rubber, Denim, Ceramics, Plastic, Velvet, Leather, Castor Oil, and Paper

Insulators Used in Construction:

Some eco-friendly materials used in buildings for insulation purposes include...

• Sheep’s wool

• Icynene (spray made from castor oil)

• Polystyrene (foam spray or rigid foam boards)

• Aerogel (man-made material that’s 90% air)

• ThermaCork (made from outer bark of oak trees)

• Cellulose (made from recycled newspapers)

Why do conductors allow heat flow? 

These specific materials permit electrons to transfer easily from one atom to the next, and have free electrons on their surfaces, which allows heat (and electricity) to pass through easily.

Good Conductors:

• Metals, water, and glass (at high temp)
