You ask how the "streamlined quality" manifests itself? The material appears porous, the surface suffers from the weather. Even the white plastic shows porosity as it grays and displays slight streaks. If I may describe my work, then the search for traces on smooth surfaces with soot powder is very successful, even on new plastic windows, but I have less success when the material is older: consequently no longer smooth (macro or micro level), dull, porous, aging. Vulnerable.

Ultimately, it remains a matter of personal taste and I certainly did not want to give the impression that I had found the philosopher's stone. It was just my personal opinion on the subject. Where I grew up, almost all windows were made of wood and painted white. That was ages ago and therefore my remark and opinion "white always works". Exactly 20 years ago, we had white plastic windows from Weru installed in our current house. It may be negligence, but I have not noticed that they look sleek now. With wooden windows that have not been painted for 20 years, that would certainly be the case. If money were no object, I would definitely prefer wood-aluminum windows. I only took the liberty of passing on my information and did not want to give the impression that I am an expert.

Last week, together with my wife, I decided on such a colored window for our bedroom. But if you want to exchange the windows with such colored ones, everything ends up being really expensive. Our daughter, who lives in Spain, got such colored window films in pink for her a month ago and said that the color effect is really intense. Therefore, I researched where you can buy such films cheaply in Germany. I found and ordered them online yesterday, so let's see if it will work well for us.

So here a lot is being mixed up. 1.) Plastic can become brittle due to temperature/UV, but that does not mean that this is always the case. Furthermore, the "worn" surface does not result from brittleness, but the material is simply stressed and worn by wind (particles), water, chemicals, etc. You can see the same with metals and wood. Glass and paints are somewhat less sensitive, but anyone who looks at the windows and paint of their 20-year-old car will probably notice that they are no longer like new either. 2.) Plastic, glass, and metal have different coefficients of thermal expansion, but this is independent of the color of the window. Dark films CAN increase the surface temperature, but since plastic is a good insulator, this only applies to the near-surface layers. In addition, the plastic on the outside always heats up more than the inside of the house. Furthermore, those who argue with expansions here should take a look at the difference in the coefficients of thermal expansion of glass, plastic, and aluminum. If the few degrees difference caused by a dark film were already a problem, then no window would be tight anymore and the panes would fall out everywhere. 3.) Sure, some plastic windows no longer look like new. But as already mentioned, these have only been standard for 40 years. Metals and wood have been used for centuries. In the field of plastics, development has progressed enormously since the 1970s, while the other material sectors have only developed slightly. This means: Even if they are still white, plastic windows from the 1980s are not comparable to the current standard.
