Why Size Matters: R-value with loghomes

R-value is a widely used measure to determine the thermal resistance of building materials. It is a measure of a material's ability to resist heat flow and is commonly used to evaluate the insulation properties of walls, roofs, and floors. The higher the R-value, the greater a material's ability to insulate and slow down heat flow. Log homes are a unique and natural way to build a home, and many people find them appealing due to their rustic charm. However, log homes typically have a lower R-value compared to stick-built homes.


The R-value for a log home can vary depending on the type of wood and the thickness of the logs used, but generally, it ranges from R-2 to R-4 per inch. This is lower than typical stick-built homes which can have an R-value of up to R-20 per inch. To improve the insulation in a log home, insulation is added between the logs in our EZE-Panels. Additionally, insulated windows can also be installed, which can help to prevent heat loss through the windows, making your planned home more energy-efficient.

But taking only the R-value of a new build into consideration is wrong.

Another benefit of log homes is that they have a high thermal mass. Thermal mass is the ability of a material to absorb, store and release heat. Logs have a high thermal mass, which means they can absorb and store heat during the day and release it at night, helping to keep the home at a consistent temperature. This can be especially beneficial in climates with extreme temperature fluctuations. The thermal mass of the logs can provide an additional benefit to keep the home at a consistent temperature. In addition, log homes are also a sustainable option as they are made of natural materials, and can be made from locally sourced wood. In comparison is the thermal mass of a stick home is very low.


To improve the energy efficiency of your log home, it is important to work with professionals who have experience with log homes and can advise you on the best way to improve the insulation. They can help you understand the different types of insulation options available and recommend the best one for your home. They can also help you understand the proper installation technique for each type of insulation and advise you on the best way to seal and caulk the logs to prevent drafts and energy loss.


Log homes are a unique and natural way to build a home, and with some adjustments, they can be made as energy-efficient as stick-built homes. The rustic charm and natural insulation properties of log homes make them a great option for those who want to live in a home that is both beautiful and sustainable. With the right insulation and energy-efficient windows, log homes can be made just as energy efficient as stick-built homes.
