What is the R-Value of your log homes?

R-Value measures the performance of an INSULATED wall. Since a log wall is a solid mass (there is no insulated space), R-Value does not apply correctly. The log home is measured by Thermal Mass. The studies that have been done on the differences between insulated walls vs. solid log walls point out that a solid log wall is superior based on the average costs for heating and cooling.
Note: The R-Value for our standard insulated roof system is R-38.
