The R-value of a log home wall is dependent on the type of wood used. The logs in such walls provide both structural support and insulation against heat flow. The R-value is used to determine the thermal resistance or the ability to resist the flow of heat. Here are the R-values of various types of wood used in a solid log wall:
Softwoods such as pine have an R-value of 1.41 per inch (2.54 centimeters).
For most hardwoods, the R-value is around 0.71 per inch (2.54 centimeters).
It’s important to keep in mind that log homes are unique and the R-value of a wall is determined by various factors such as the thickness of the logs, the number of logs used, and the quality of the construction. Despite this, log homes are excellent at maintaining their temperature and insulation, making them a great energy-efficient option for homeowners.
