Log Cabin Storm Bars
A storm bar is a long baton of wood which is fixed externally to the 4 corners of the log cabin.
It is bolted to the cabin at the top and bottom.
At the bottom there is a large oval slot for the bolt to go through. This allows the storm bar to move up and down as the walls settle and then expand and contract in the different temperatures and humidities.
The purpose of the weather bar is to help protect the building from damage when it is windy. A storm bar cannot prevent damage to a log cabin in very strong winds.
It works by fixing the top wall logs to the bottom ones. The bottom wall logs are held down by the total weight of the cabin.
