Is anyone aware of a software that calculates U-values of typical
construction assemblies? I'm not looking for something as complicated as
THERM, but more along the lines of a program with a database of common
materials and typical framing factors that will allow me to calculate
U-values quickly without thumbing through my ASHRAE fundamentals handbook
or my local energy code.

Also, the units would need to be in IP.

Thanks for your help,
