Energy Efficiency

Log homes have a deserved reputation for energy efficiency. Tests performed by the federal government found a log structure to perform as well or better than other types of construction, including an R-11 insulated 2x4 framed wall structure, even though the nominal R-value of the log wall was less than nine.

Experts attribute the energy efficiency of log homes to thermal mass of the solid wood walls. In addition, a well-sealed and maintained log home does not exhibit the energy loss due to convection or air infiltration that is characteristic of framed wall construction. Although log homes have inherent energy efficiency, this can be offset by poor construction or maintenance. Log home manufacturers provide specific construction details and maintenance guidelines to ensure that homeowners realize the full benefit of log construction. If these guidelines are not followed, the result may be high utility bills.
