Window flashing - disagreement with the builder about the projection
We have changed the facade and windows. The windows are flush with the facade. Today when I came home, the builders had installed window sills that in my opinion are way too large.
The upper window sills stick out and drop down so much that a couple of centimeters of the cornices disappear behind them, and thus the most beautiful profiling. He received a picture of how we wanted it, and it was not like this.
The lower window sill also sticks out way too much. I reacted immediately when I saw it. I have read that the industry's minimum requirement is that it should stick out 20 mm beyond the facade or the casing. The longer the better possibly, purely functionally speaking, but certainly not aesthetically. Furthermore, they stick out so much that one could get injured on them where they are at ground level. Here, we're talking about approximately 50 mm beyond the casing!
Our builder claims that there are building regulations for how far the lower window sills must stick out, and that he has followed them.
I understand that the window sills below must be shorter than those above, so that it doesn't drip on the lower plate as soon as it rains. So we need to correct both.
I am really getting fed up with building now. Builders are not so careful to ask or follow what we want aesthetically - for example, the builders did the casings differently from the drawing and from what I explicitly said and wrote.
We are extending our older house in an old style and I am particular about the details. For the children's sake, I had to take them away from the construction dust for a few days. Otherwise, I would have noticed it earlier. My partner was home but doesn't notice things like this.

What is worse, I think there appears to be a backward slope on the upper flashing; it also has the upturned edge behind the panel as far as I can see. If it is as it looks, it leads moisture into the panel. In other words, it would be better if it weren't there.

40mm protrusion from the trim according to husama, but if it's places people walk frequently and risk getting caught on them, I usually make them smaller...
The flashing should have had just a single bend instead of a drip edge; it also works for lower flashings if you want an old-fashioned style. (I guess the builder bought ready-made flashings from the hardware store and that's why they're those measurements.... Order from a tinsmith instead)

what is "ankantning"? Do you mean the fold?plåtrickard said:

The overflashing should have been with just an "ankantning" instead of a drip edge, works also on the lower flashing if you want an old style. (I guess the builder bought ready-made flashings at the hardware store and therefore gets such dimensions.... Order from a sheet metal worker instead)
Yes, it is behind the panel. But I have explicitly said and written that it must slope slightly outward. Hopefully, it's just the picture that's misleading. Will check again!D Daniel 109 said:
Are you referring to Ama Hus from Svensk Byggtjänst? No mandatory rule about 40 mm then?plåtrickard said:

The flashings should have been with just a simple edge instead of a drip edge, works also on the lower flashings if you want an old style. (I guess the builder bought ready-made flashings at the building store and therefore got such dimensions... Order from a sheet metal worker instead)
That's how stormhasps are usually placed.
