We have white film on the inside and gray on the outside.

We weren't informed about the warp or didn't think about it. Now it is, and we are waiting to see if there is anything special about it.

White plastic: from the 90's, has always gone since then, was modern and new, but not necessarily chic. Modern because it was new. It was good, cheap, practical. And it remains so to this day.

If you were a stickler for quality, you kept your glazed wooden windows or built your house with wooden windows.

This is still true today. White plastic windows are, no offense to anyone, cheap and done!

But modern? They are not modern and chic.

And after 10 years, even if they look outlandish, let's not kid ourselves – either colored and warped or white and outlandish?

Basically, plastic gets brittle over time. That's why they look frayed at some point. Maybe foil helps against brittleness? But I don't think it does.
