Grigs Posted March 3, 2009 Posted March 3, 2009 I'm looking for a program or Excel spreadsheet or something that will allow me to enter the components of a wall and calculate the R values. Does anyone know of a program/spreadsheet that will do this? Quote

Grigs Posted March 4, 2009 Author Posted March 4, 2009 Kinda. What I was looking for was something that I could enter the components of a wall and it would tell me the R value of each item plus a running total. So if, for example, I had a 8" concrete wall that was furred with 2x4 wood studs filled with batt insulation and 5/8" gyp. board it would would show the R values of each component and then a total for the wall.
