The CMHA R-Value/U-Factor Calculator is a spreadsheet-based calculator tool that determines steady state thermal properties of concrete masonry assemblies. Calculations can be performed for a wide variety of unit configurations, grouting schedules, and insulation types. Both single-wythe and multi-wythe calculations can be performed. The results can be used for determining compliance with energy codes as well as inputs for COMcheck and other energy modeling software.
