befound Reference Joint Appendix JA4.
2. This is the U -Factor based on the thickness of the assembly in inches.
3. The R -value of the insulation to be added on the interior or exterior of the assembly.
4. The Calculated R- Value is the R -value of 1hefurred out section of the assembly.
-6 The Final Assembly is calculated using Equation 4-2 or Equation 4-4of the Reference Joint Appendix JA4. The equation is the inverse of Column
addedtoColumnl. Column K is the inverse from column J
7". Insert the calculated U-Jactor value on to the Opaque Surface Details in Column J
