WebWhat is Insulation R-Value? Insulation ratings are measured in R-values per inch of thickness. An R-value tells you how well a type of insulation can keep heat from leaving or entering your home. Insulation R-values vary based on the type, thickness and density of the insulation material. WebAVERAGE R-VALUES: In order to determine the average system R-values for a tapered insulation project, the average thickness for the insulation system must first be determined. This is calculated by dividing the total volume of insulation (the board footage) by the area of insulation coverage (the square foot area).
