I am trying to figure this out too. I foudn a way to create custom parameters for the materials, so you can input a U-value, but I don't know how to sum the u-values multiplied by the thicknesses to give me the R-value.
It would be really cool to do this, especially if I can pass those parameters onto an external sotware package like Ecotect.
