Thermal Mass in Log Homes

The term, Thermal Mass, refers to the property of logs in a log home to store and delay the transfer of heat, much as stone or metal does. This property, along with the natural insulating ability of wood, is what makes log homes exceptionally energy efficient. Thermal Mass allows a log to absorb heat during the hottest part of the day and give it back during the cooler night, without transfering it through the wall.
