There are lasting benefits, too – uPVC's durability allows it to withstand the elements, so it won't rot or fade, like wood, or corrode as aluminium does.

Do uPVC windows fade?

Newer coloured UPVC windows are usually manufactured solid, which is to say the colour permeates through the UPVC. This solid colour makes the windows highly resistant to fading. However, because they are coloured, noticeable fading will still occur over a period of fifteen to thirty years no matter their durability.

Do uPVC windows fade in the sun?

Black UPVC windows do fade over time. Claims of 'advanced manufacturing processes' are in most cases exaggerated. When exposed to UV light over a period of ten to fifteen years, black UPVC greys out and the finish dulls.
