It depends on the application. Ceramics are probably the best without specifics. Fiberglass and aluminum foils are also very good it certain situations.
Insulation
yes the R-value does indicate resistance to heat flow
Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and its density. In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added.
Insulation products are used to prevent energy loss. Hope it helped. :)
Viscosity is the resistance to flow of a substance. The higher the viscosity, the more resistant it is to flow. That is to say, glue has a higher viscosity than water.

Floors, attics and walls all require insulation of different R-Values which are measured by the thickness of the insulation. The R-Value determines how well the insulation will resist heat flow. The higher the R-Value the more resistance it has to heat and cold. If you are adding to existing insulation there is another factor to consider. You will have to determine the R-Value of the existing to know how much additional insulation to add
dunnooo...thats what ive been trying to find out too...

Heat insulation reduces the rate of heat flow. Sound insulation reduces the amplitude of the sound energy transmitted through a cavity.

A dielectric, insulator or insulation Is a substance that inhibits or stops the flow of free elections
