Hello, I'm dealing with the topic of windows right now.
I've actually always wanted to have wood-aluminum windows. I have also considered the extra cost. I have been told that wood-aluminum is slowly disappearing from the market as it will rot on the outside under the aluminum in the long run.
Has anyone been doing this for a long time?
Pure aluminum windows are also rarely in demand in private homes.
The problem with plastic is that it deforms / swells the first time it heats up too much.
This is especially true for dark, large-format windows.
The conclusion we made for ourselves: plastic windows in dark color never again or only in small format.
For us, the most important argument was ease of maintenance, and unfortunately, plastic is second to none here. The outside is imitation wood, I don't think anyone else recognized it, everyone keeps asking us why we got wood windows, they are so time consuming to maintain. Inside, we only like the white windows and doors, although we are otherwise quite a fan of wood (parquet everywhere ...), because plastic is just the most practical.
If you pay attention to quality products, they also last as long as aluminum/wood. And even if they don't ... in 40 years the technology will still be so outdated that new windows will be added to the house ... who knows what will become possible then.
So, the service life of plastic windows is about 20 years, of wood-aluminum is about 35 years. This means that the additional investment definitely pays off. And not to mention the higher quality of life.
Take wood-aluminum, we have been using it for several years in our new building and are very happy with it. However, we were getting very different offers at the time, so it's really worth comparing. The price range is about 50%!
