Aluminum is an excellent heat and electricity conductor and in relation to its weight is almost twice as good a conductor as copper.

Materials that make good heat conductors are usually those with lots of free electrons. Metals are good conductors because they have lots of free electrons to play with. Aluminum, for example, is a far superior conductor to water.

Answer: Materials that allow heat to pass through them easily are called good conductors of heat. Metals like copper and aluminium have the highest thermal conductivity while steel and bronze have the lowest. As copper is an excellent conductor of heat, it is good for heat exchanger also.

Metals are particularly good conductors of heat because their particles are very closely packed so the vibrations are passed on very quickly. This makes them move faster and they travel through the metal, colliding with both atoms and other electrons.

Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of heat.

Certainly, bubble wrap can absolutely be used to keep things cold. Bubble wrap acts as an excellent insulator. The small air bubbles do an excellent job of slowing down the transfer of heat between air molecules. There are so many options and ways to use bubble wrap to control all of your temperature needs.

How to Keep a Room Facing the Sun Cool

1. Window Treatments. Drapes, curtains and blinds enable you to control the amount of sunlight that enters the room.
2. Awnings. While awnings don’t directly affect the temperature inside a room, they can aid in the ventilation of your home reducing the level of humidity.
3. Windows.

Bubble wrap will increase the resistance to heat flow by a factor of one. As bubble wrap has air and also an added benefit of cavity wall insulation, it is an excellent barrier to heat loss. Bubble wrap, if used as an insulator, is comparatively cheaper than many other traditional insulators.

Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces.
