Film coatings on windows - durability experiences?

Dear community,

what are your experiences with foil coatings? Some providers offer "Renolit foil" as a coating for the actually white plastic windows during sampling. They also offer a 5-year or longer warranty. But how durable are these foils? Apparently, there are no windows that, for example, are dyed all the way through in anthracite or similar and do without foil...

However, Gealan offers such windows. Not in all colors but in some. I have no experience myself with either foil or the acrylcolor windows from Gealan. I have the standard traffic white windows from Gealan.

Thank you for the hint. It's just annoying when you're tied to the windows of the GU :-(
Are the Gealan windows much more expensive than the foil-coated windows?

Apparently there are no windows that, for example, are colored all the way through in anthracite or similar and do without film...

Not colored all the way through, but coextruded: from Gealan. Hopefully, you have informed yourself about the keywords cracking and shading before you possibly expose dark windows in large formats on the south side (?)

Oh, no...I will catch up! I want to install two-wing 2m floor-to-ceiling windows facing south:p
