Roof battens dimensions - a small overview


There are numerous dimensions of the roof battens, depending on which cross section and which length is needed. Various DIN regulations have also determined certain dimensions of battens. Here we show a small overview of the common sizes.

Roof battens - the substructure

Roof battens cover the roof and are nailed transversely to the upright rafters. DIN 4074 Part 1 specifies the exact cross sections and quality grades for roof battens.

This delineates the roof batten from a standard lath that can not be used on the roof. First and foremost, it is important for a batten to be viable and firm.

Therefore, only a certain number of branches may be present in a roof batten. Due to this fact, the roof batten is also very attractive for DIY enthusiasts indoors.

Residual moisture in the batten

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