Richtig, Bernd... ... dann schlag das doch mal als Antwort vor :-)

Gefälle Auch ein Flachdach braucht ein wenig Gefälle, damit das Regenwasser kontrolliert und schnell ablaufen kann. Hier werden roof battens which provide a sloping of XY % eingesetzt.

Unfortunately... there is nothing else to go on apart from the line included above. The other two components of the flat roof are a PVC membrane and wooden boards. The Holzlattung / Gefälleausbildung is the third and final entry in the list, so I would assume forms the top surface of the flat roof.

do the slats serve to form the gradient? or does Gefälleausbildung refer to a separate material?

Sarah Bessioud (asker) Apr 9, 2010:

I'm not sure it is filled as such... What about 'gradient building'?

Sarah Bessioud (asker) Apr 9, 2010:

Hello Johathan I think you are right, it is something used to form a gradient. (An illustration of what is meant (I think!) can be seen here: http://allpir.de/downloads/22_O_GF_030_09.pdf.) Unfortunately, I am still at a loss as to how to translate this.

gradient former wood used to form a gradient?? Or are these "angles" that form the gradient between the boards??
