Insulation R-Values

Materials vary enormously in their ability to conduct heat. Those that do not conduct it well are called insulators. R-value is the term used to indicate a material's

• resistance to heat flow or
• ability to insulate.
  
  The higher the R-value, the better the insulator.

How insulation materials work
Most insulation materials work by trapping pockets of air, which is an excellent insulator. Examples are listed in the table below.

Selecting insulating materials
Among insulating materials R-values can vary widely. This is the reason it is important to purchase insulation by R-value and not by the inch. R-values of materials can be compared while thickness cannot. Two materials rated R-11 have precisely the same insulating ability, but 2 inches of the same R-11 materials may not.

Example: Fiberglass and brick. To achieve R-30 with fiberglass batts requires 8.5 inches, it would take 60 inches of brick to attain the same rating.

Insulation R-Values

R-value per inch for common materials

The table below lists the R-value per inch of some common materials.

Inches of material needed to reach R-value comparison

The following table lists the inches of each material required to reach 5 different R-values: R-11, R-13, R-19, R-22 and R-30. The comparisons can be helpful when selecting the insulation material in situations where space is limited.
