Wood/Aluminum windows with Helopal or aluminum exterior window sill?

Hello,

we have decided on wood-aluminum windows from Internorm. The exterior color will be RAL 7016 (Anthracite). Aluminum (also RAL 7016) is currently planned for the exterior windowsills.

However, we are now considering switching to Helopal for the exterior windowsills. Allegedly, it looks more high-quality, but what appeals to us more is that it is quieter when it rains. What do you think about that?

And if Helopal, would you then - if available - advocate for RAL 7016 or a neutral color that contrasts with the window?

Thanks

How are we supposed to answer that "blindly"? - just link where we have already seen your [Fassade].

It doesn't exist yet. Everything is still in my head. But it will probably be a light green (provided my wife doesn't change her mind again)

but for the first step the first part of the question would be more important to me anyway. helopal or aluminum? just in terms of the material alone. what are the advantages and disadvantages?

Supposedly it looks more high-quality, but what appeals to us more: it is quieter when it rains. What do you say about that?

I have never had noise on a windowsill from rain in my life. Neither with aluminum (just freshly installed - no roof overhang at the ridge sides), granite, or anything else.
When installed correctly, you hear nothing with aluminum.

Well, I have the "noise" of raindrops on an aluminum windowsill. I wouldn't choose that again.
