Hello everyone,

When I read about the slope of window sills, I keep seeing a minimum of 5° mentioned.

Unfortunately, I can’t find any official guideline on this! The only one I found is from Austria, which obviously doesn’t apply to Germany.

Can someone tell me where I can find a precise description? I’m asking because I have the impression that the slope is incorrect everywhere here.
In winter, the roller shutters freeze shut due to frost, and I suspect it’s because the slope is too shallow.

Has the Rosenheim Institute or RAL published anything on this topic?

Thanks a lot!

Best regards

As far as I know, there are no binding regulations in Germany. However, there are guidelines (glazing trade, Rosenheim) that recommend a minimum slope of 5 degrees.

Do you have the guideline at hand? Name or possibly guideline number?

What is the name of the lady with the Heinz von Heiden house? They had a legal dispute and had all the window sills replaced. By the way, even if the slope is sufficient, the roller shutter sticks to the window sill.

Could someone please provide me with the above-mentioned regulations? The detailed part would be sufficient.
Does anyone have them?
