Insulation is measured by its R-value, - it's resistance to heat flow. The higher the number, the more blocking capacity or insulating it provides. Different materials have different heat blocking capabilities, therefore different R-values. As well, the thickness of the insulation, where it's installed and how well it's installed will determine the total R-value of the insulation in your home. Since R- values are cumulative (they add together) the total R-value is the sum of the R-values of the insulation in any particular area of your home.
