This separates the roof batten from a normal batten that cannot be used on the roof. First and foremost, a roof batten depends on its load-bearing capacity and strength.

Therefore, there may only be a certain number of branches in a roof batten. Due to this fact, the roof batten is also often very attractive for do-it-yourselfers indoors.

Residual moisture in the batten

According to the DIN standard, a roof batten may only contain a residual moisture of 20 percent. If necessary, the sawmill has to dry the roof battens that far down in certain drying chambers.
