![]() ![]() Warmer drier air inside means more and faster drying of logs that are in contact with that air than logs in contact with the outside colder more humid air. ![]() Unless we do something to change the humidity level inside this will always be the case. Cold normally more humid air outside and warmer drier air inside. If the joinery is to create a barrier between inside and outside as well as the logs both must react to different conditions meaning different temperatures and different air moisture levels. This creates one of the most important challenges for log joinery. Using logs for shelter implies that logs will become a barrier between temperatures of different levels of comfort. Today aesthetics probably plays an equal perhaps more important role in people choosing logs as a construction material. The reasons then and now for using logs as a building material is that they can provide the best quality shelter in more drastic climates. Log construction began thousands of years ago probably in more northern climates where large forests were close at hand. That’s not to say that these characteristics can not be controlled or in some ways used to a benefit but it is impossible in log construction not to be effected by the drying out or swelling up of wood. #Groove scribe crackThis applies to wood even thousands of years old! If a manufacturer of log homes claims that their logs will not “shrink”, warp, twist, crack or settle, this will only be true if their logs are made of something other than wood. Non living wood by its nature will always attempt to equalize its moisture content with the air it is in contact with. Logs – wood is a by-product of living things, trees. ![]() Lets start with some basic understandings. #Groove scribe fullThis article will deal with full scribe joinery but the principals apply to all forms of log joinery, even manufactured log construction. To the average log home purchaser trying to understand why there are so many different forms of log construction joinery and which is best for what reasons is a mystery.
