2.3: Mesh widths for different lightning protection
classes
The mesh method used exclus-
ively the basis the lightning
protection class. If, our example, the
overall length greater than the recommended size
indicated Table 2. loop size must
therefore not exceeded.
The building our example has building lightning pro-
tection class III.3, expansion piece must also
be integrated for temperature-controlled length
changes.1
