Why Do Composite Doors Fade?

Choosing the colour for your new composite door is often the most rewarding part of the design stage. We’ve seen our customers get excited about the style and hardware plenty of times, but nothing lights up faces quite as much as picking the colour. Whether you go for a vibrant red, a versatile grey, a neutral claystone door or one of the many other options, the colour is a way to add a touch of your personality.

So we can understand how frustrating it would be if the colour faded after a few years. Here at Endurance Doors, we’ve taken steps to reduce fading, but for a lot of other composite doors on the market, it’s a big problem. But why does it happen? And how have we managed to avoid it? Let’s take a closer look at fading composite door colours.

The thing to bear in mind is that colours don’t fade overnight. It’s a slow process that’s caused by prolonged exposure to UV rays. You certainly won’t go to bed one night and wake up to find your door’s appearance has dramatically changed, quite the opposite. The colour degrades so slowly that most people don’t realise until it’s impossible to overlook.


This happens because the composite door industry has relied on paint for a long time. Regular composite doors are often hand-painted and while this does have advantages, it’s vulnerable to sunlight. You may be able to select from a massive range of RAL colours, but your door will also absorb UV energy and fade, crack and peel. 

The good news is that we’ve managed to significantly limit the chances of our doors fading. We’ve always been interested in groundbreaking advances, so when we learned about CoolSkin technology, we jumped at the chance to use it. Our doors are fitted with uPVC foiled skins, so when the sun shines directly on them, they reflect UV energy rather than absorb it. 

In layman’s terms, this means that the doors retain their colour for far longer. Once the summer ends, it’ll look as vibrant and eye-catching as it did when you first bought it. And it’ll be the same next summer, and the summer after that. The UPVC foiled skin extends the lifespan of a composite door and decades from now, it’ll still look as good as the day it was installed. 

The one drawback is that if you change your mind and decide you want a different colour, it can’t simply be repainted. However, we’ve noticed that this rarely happens. We’ve installed hundreds of composite doors over the years, and have been asked about changing a colour only a handful of times. 

In other words, while fading paint is an issue for some composite doors, it isn’t for Endurance. If you want your front door to retain its good looks and save yourself the inconvenience of having to repaint it, we can help. And before you ask, yes, you still get an enormous number of colours to choose from. You can see the quality first hand by visiting our showroom or checking out our colour collection.
