The true insulation on the exterior wall if you are measuring in R values only have been R-14.

R value in an exterior wall is not near as important as people think that it is. That is a rumor and it is not a good one. I measure the utility usage or the energy usage of every home I built for 15 years on a monthly basis and what I learned that can do is take a fairly standard house with fairly standard parts -- you know, wood frame and things like -- in the Dallas area and build, say, a 2,500 square foot home where you can cool for about a dollar a day or a little bit less. That's $30 a month, and these were fairly conventional homes. Nothing really unusual. My smaller homes are historically heated and cooled for about 35 cents a day - that's less than $13 a month.
