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.
