In the chart above, you will notice that there are two vastly different R-values provided for insulated metal doors with polyurethane insulation. Based on ASTM C518 (Calculation Method) the door has an R-value of up to 11, but using ASTM C1363 (Tested/Operable) the same door only have an R-value of … See more In construction, the R-value is the measurement of a material's capacity to resist heat flowfrom one side to the other. In simple terms, R-values measure the effectiveness of insulation and a higher number represents … See more As we said before, the R-value measures the thermal resistance of a material. This can also be expressed as the temperature difference that will cause one unit of heat to pass through one … See more The R-values for specific assemblies like doors and glazing in the table below are generalizations because they can vary significantly based on special materials that the manufacturer … See more Many energy modeling programs and code calculations require U-factors (sometimes called U-values) of assemblies. The U-factor is the heat transfer coefficient, … See more WebAug 15, 2016 · Reference Table for "U" Values "U" Value is the coefficient of transmission, i.e., the transmission of heat through the materials, which compose the building's "envelope," or outer shell. "U" Value has an inverse relationship to "R" Value. For example, a building with material with an "R" Value of R-11 converts to an "U" Value of 0.09 ( 1/R …
