U-factor 0.060 0.054 0.045 Effective R of wall 17 19 22 U-factor Comparison The R20+5ci wall is 15% more efficient than the R-25 wall. This is because the R-5ci creates a thermal break at the stud and header locations. According to the U-factor compliance table, the R20+5ci will work in any climate zone for thermal performance. Moisture control performance is addressed later as a separate check. The R-25 and R-20 walls are suitable for climate R values rate how much heat loss the material resists from passing through it. U-values rate how much heat the component allows to pass through it.

Because ER values are derived from a formula that uses both the U-factor and solar heat gain, there is no method to directly convert the ER value to an R-value.
While they are technically very different, in terms of energy efficiency they are used in the same context. R Value is Imperial, while RSI is Metric, and both have a U value equivalent.
Both of these figures provide a rating of a garage door's thermal efficiency, but in different ways .
Example: My contractor has given me a quote for five new windows that I would like to replace. My contractor says they have a U-factor in imperial units (Btu/h·ft 2 ·F) of 0.21 and I want to know what that is in metric units.

Many energy modeling programs and code calculations require U-factors (sometimes called U-values) of assemblies. The U-factor is the heat transfer coefficient, which simply means that is is a measure of an assembly's capacity to transfer thermal energy across its thickness. The U-factor of an assembly is the reciprocal of the total R-value of the assembly. The equation is shown below. U Factor Equation Tables of Building Material R-values
Step 3 A U-value is typically a low number because it is a rating of how much heat energy is lost or gained. If we look at the two values mathematically, U-value is the reciprocal of R-value; that is, U = 1/R and R = 1/U. For example, a material with an R-Value of 5 has a U-value of 0.2 (1 divided by 5).
