Windows and doors from a single source or not? – Experiences?

I think coextrusion is good, but it probably isn't done very often?

Very good at Gealan in a wide range of colors at a good price. Otherwise a niche.

Thanks. My wife wants gray windows (inside and outside)

Bold. I find colored windows on the inside horrible, especially with white walls. It’s always an eye-catcher – even if you don’t want it to be. Therefore for me personally a no-go.

May I ask what is bad about modern PVC windows?

There are very good ones. Basically not bad.

Thank you. My wife wants gray windows (inside and outside) and in the end the extra cost for plastic + foiling compared to aluminum might not be that high...

The color should be available without special production, so no special surcharge.

A lift-and-slide door or front door can also be purchased in plastic. But for these areas, there are better frame materials - namely aluminum.

With dark foil, the plastic version is not ideal because it tends to warp with direct sun exposure. We have 4 plastic patio doors - the next time I would have them executed as front doors - not a big mistake but they say you build the first house for the enemy, the second for a friend, and the third for yourself. We still need one. I also tend towards aluminum.
