Sidewall R-Factor

In your construction download under Sidewall it shows a composite R factor of R-10 . Under specifications it shows Sidewall R-value of R-7. Is there a difference between R - factor and R -value ?

I believe the R factor included the sheeting and outer skin that is used to make the composite wall. The R value is just for the insulation itself that is used in the wall construction.
Anytime you add sheets of OSB, plywood, filon or similar they do have a minimal R value which is then added to the R value of the insulation.

R-Value

We are in the process of updating our information on the web concerning the R-value. What you are asking about is a typo concerning the sidewall R-value. While the composite wall components do add to the R-value-we will probably end up showing a sidewall R-value of R-7 for the Sundance. Thanks for your interest in Heartland RV.

Thanks for both comments on this ?
