R-value = temperature difference × area × time ÷ heat loss Insulation R-value ratings can vary based on the type, thickness, and density of the insulation material. For home improvement work, standard insulation R-values range from R-10 to R-60, depending on where the insulation is inst...
So, the R-value Rule requires testing insulation using one of 4 American Society of Test Methods (ASTM) standards. The basic requirement is that the mean temperature must be 75° F (24° C) with a temperature difference of 50° F (28° C) across the insulation. According...
SeeColoradoENERGY.org-R-ValueTablefor an excellent detailed list of product R-values. The value of proper insulation can be illustrated by comparing a fiberglass batt’s R-value to poured concrete. A 3.5-inch thick fiberglass batt provides R-11. To achieve the same R-value, poured concrete ...
insulationcompression.Fiberglass batt insulations intended for use in buildings are labeled with an R-value and a thickness at which the R-value is achieved. In some cases the insulation is installed in such a way that the label thickness is not achieved. The material R-value of fiberglass ...

As an industry, we tend to equate the R-value of a building’s exterior walls with the R-value of the insulation in the assembly. For example, a 2x4, 16-inch-on-center wood-framed wall that is using an R-15 batt is labeled as an R-15 wall. This is where the standard and real...

–A measure of insulation. A measure of a materials resistance to the passage of heat. The higher the R value, the more insulating “power” it has. For example, typical new home’s walls are usually insulated with 4″ of batt insulation with an R value of R-13, and a ceiling insula...
