What is the difference between kiln-dried and air-dried logs?
All logs are cut green in a forest and are then dried. The kiln-dried logs are put in a large lumber kiln and are dried to moisture content of around 15%. Then the kiln-dried logs are either sent to the job site or put in storage until sold. As soon as this happens, the kiln–dried log begins the natural process of adjusting to its environment. Whatever the level of humidity is that day, the log will try and reach equilibrium with the air in the environment. This is the same procedure an air-dried log goes through. The gain and loss of moisture in wood is a never ending process that varies with the daily weather. So, kiln-dried or air-dried logs end up the same when you understand that the moisture content of the logs is a function of the local climate, regardless of how the log is dried. At All Phases Construction, we offer both kiln-dried or air-dried logs.
