The similarities between heat and sound insulators is very small. [The names are imprecise.]
A Sound Absorber, to give it its proper name, is usually a light fibrous material such as cotton waste or open-cell foam. It is possible that the sound level in a room might be reduced by perhaps 10dB or so by the use of sound absorbers.
Porosity is often an important property of a sound absorber.
A Sound Barrier on the other hand stops sound from travelling from one place to another. Mass and non-porosity are the important properties of a sound barrier material. Concrete or drywall board are quite good sound barriers. A good sound barrier will reduce sound by about 50 dB or so.
A heat insulator is a material with low thermal conductivity.
Porcelain, or mica sheet are good heat insulators. A Vacuum Flask is a good heat insulator.
Often, but not always, a high melting point is an advantage.

Is a stick a conductor or a insulators?
An insulator for heat and (less so) for electricity. A conductor for sound and vibration.
Are insulators good conductor of heat?
Insulators are the complete opposite of conductors. Insulators insulate the heat, but conductors let it pass straight through.
What are the 3 best insulators?
For Sound, lead or massive concrete; for Heat, fibrous non-conducting materials such as fibreglass and asbestos; for Electricity, ceramics, glass, and plastics.Note, a vacuum is an almost trivial answer for both heat and sound.
What are heat conductors and heat insulators?
the substances that allow heat to pass through them easily are called heat conductors. the substances that do not allow heat to pass through them easily are called heat insulators. ruchi
What is the name for materials that do not allow heat to pass?
Materials that do not allow heat to pass are insulators. (In real life, there are no perfect insulators, but if not much heat passes, then it is an insulator.)
Name 2 insulators?
Insulators are materials or substances that do not readily allow the passage of sound or heat. Two examples of insulators are glass and porcelain.
What is the definition of the word insulators?
"A substance that does not readily allow the passage of heat or sound."

Insulators are the complete opposite of conductors. Insulators insulate the heat, but conductors let it pass straight through.
What are insulators of heat?
The substances that don't conduct heat through them are called as 'insulators of heat'. Eg - Plastic, Wood etc.

What is in an example of a good insulator?
A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators.
What is the name for materials that do not allow heat to pass?
Materials that do not allow heat to pass are insulators. (In real life, there are no perfect insulators, but if not much heat passes, then it is an insulator.)
Good insulators of heat?
nonmetals
What are some heat insulators?
Some heat insulators are fiberglass, polyurethane foam, and polystyrene. Two other thermal insulators used as insulating materials in building construction are mineral wool and cellular glass.
What is a good insulators against heat?
rubber
