Black aluminum windows - problems to expect?

We are currently selecting samples for our house and basically want dark windows inside and out, if possible deep black RAL9005. Based on posts including from 11ant here in the forum, we have now chosen aluminum windows with the MB-86N SI profile from Aluprof (via Eko Okna). Plastic with aluminum cladding would mean foil on the inside, and we find the durability there too uncertain. The surcharge compared to plastic-aluminum is acceptable with the dealer we found (about €10,000). Nevertheless, we are wondering whether the color will really work long-term. It is a powder coating and it is likely to fade over time. What does one do then? We are also still unsure about sun exposure/heat and whether the aluminum windows might warp over time or become extremely hot (because inside, not everything is aluminum for insulation). Maybe they will crack then or is that more of an issue with wood-aluminum? Would it help a lot to make the windows slightly lighter (RAL7016, which is the "standard") and perhaps only do everything inside in RAL9005? Maybe someone here has experience?

Possibly the DB703 would also be suitable because it is supposed to be "long-term stable" due to the iron mica?

If you write instead of 11ant, you directly call the colleague to it

If you don’t put the house in a cleanroom greenhouse but in normal ambient air, I strongly advise against deep black. Even customers with black cars and black pianos have never ordered their aluminum windows from us darker than bitter chocolate brown, and pozziblau at least wouldn’t suit everyone. PVC with aluminum is like cheap champagne, better a good sparkling wine. We cannot estimate the surcharge since we don’t know your house at all. Introduce it here once. Where you can find my post "Barrier-free window doors thanks to flat thresholds," I’d be happy to also give you my individual input.

Regardless of coating details, every one of our windows still looked factory new after more than forty years.

We are also still uncertain about sun exposure/heat and whether the aluminum windows might warp over time or just get extremely hot (because not everything inside is aluminum for insulation). Maybe they will crack as well or is that more something with wood-aluminum? Would it help a lot to make the windows slightly lighter (RAL7016 as the "standard") and maybe only do everything inside in RAL9005? Maybe someone here has experience?

Neither cracking nor warping happened there, not even in high summer. 7016 is the new boring standard, which not only I would never choose, but it would also be an extreme drop from deep black to there – less because of the color tone, more due to the downright disgusting ordinariness. You can wonderfully coat inside independently from outside with aluminum, or even foil it in a deceivingly authentic wood look. The budget scale is open-ended upwards. And no, the profile is made of aluminum inside as well; the insulation is roughly in the glass plane.

By the way: if you want to belong to the trendsetter avant-garde, simply take folding or double-wing instead of lift-and-slide (that will soon go out of fashion).

DB703 - on aluminum - I chose it and find it sensational!!! Thanks again to the great field sales representative - without him I would never have discovered the color... Only on the outside, inside white....
