U-FACTOR CONVERSION TO R-VALUE

Windows, skylights, and doors are not generally assigned with an R-value when they are being tested. Nevertheless, window salespeople and contractors may often refer to an R-value for measuring the window performance. R-value serves as a measure of the resistance to the flow of heat. In order to understand this R-value system in a better way, you can sample U-factors in metric as well as imperial units that have been perfectly converted to the R-values in the following table. Since the ER values are actually derived from a mathematical formula that makes use of the U-factor as well as solar heat gain, there’s no method for directly converting the ER value into an R-value.
