Wood Shrinking

Because the logs of a wooden house shrink slightly (approximately 1% for laminated wood), we need to take special precautions. When mounting vertical battens to the log walls (to support insulation for instance) we need to make sure that the logs can slide, or shift. See the photo.

The vertical battens are connected to the logs with a sliding profile. shrinking logs in a wooden log house

Note the right-most screw: it is not in a simple hole, but in a vertical longitudinal opening. If the top log goes down, it will take the vertical batten with it, which then can slide over the lower logs.
