Does Coloured uPVC Fade?

When it comes to choosing materials for your home, durability and aesthetic appeal are often at the top of the list. Coloured uPVC (unplasticised polyvinyl chloride) has gained popularity as a versatile and stylish option for windows and doors. However, a common concern that homeowners have is whether coloured uPVC trims fades over time. In this blog, we’ll delve into the world of coloured uPVC and examine its resistance to fading, helping you make an informed decision for your home improvement projects. 

Understanding Coloured uPVC

uPVC is a durable and low-maintenance material that has been widely used in windows and doors for decades. Traditionally, uPVC products have been available in white or other neutral colours. However, advancements in technology now allow uPVC to be manufactured in a wide range of vibrant colours, giving homeowners more design options.

Does Coloured uPVC Fade?

Fading is a common concern with any coloured material exposed to sunlight and the elements. The good news is that manufacturers have taken steps to enhance the resistance of coloured uPVC to fading. Modern coloured uPVC products are typically treated with special pigments and coating that help them retain their colour vibrancy over time.

Factors that Impact Fading

UV Protection

One of the main contributors to fading is ultraviolet (UV) radiation from the sun. UV rays can break down pigments and cause colours to fade. Coloured uPVC products are often formulated with UV stabilisers to minimise the impact of UV exposure. 

Quality of Pigments

The quality of pigments used in the manufacturing process plays a significant role in the longevity of colour. High-quality pigments are more resistant to fading and can maintain their vibrancy for longer periods.

Coating Technology

Some manufacturers apply a protective coating over the coloured uPVC to provide an additional layer of defence against fading. This coating can help shield the material from UV rays and other environmental factors.

Climate Conditions

The climate in which the uPVC products are installed can also influence fading. Intense sunlight, extreme temperatures, and other environmental factors can accelerate the fading process. 

Maintenance and Care

While modern coloured uPVC is designed to resist fading, proper maintenance and care can further extend the life of your windows and doors. Here are a few tips:

Regular Cleaning - Clean your coloured uPVC products regularly using mild detergent and water. Avoid abrasive cleaners that could damage the surface. 

Avoid Harsh Chemicals - Avoid using harsh chemicals or solvents on your coloured uPVC, as these can degrade the pigments and coatings. 

Trim Trees and Plants - If possible, trim any trees or plants that cast prolonged shadows on your uPVC window trim. This can help reduce the risk of uneven fading due to varying levels of sun exposure.

Inspect and Repair - Periodically inspect your coloured uPVC for any signs of damage or wear. Address any issues promptly to prevent further deterioration. 


In the World of home improvement, coloured uPVC offers a compelling combination of style and durability. While fading can be a concern with any coloured material, modern advancements in technology have significantly improved the resistance of coloured uPVC to fading. By choosing high-quality products, proper maintenance, and careful consideration of climate factors, homeowners can enjoy vibrant and long-lasting coloured uPVC windows and doors that enhance the beauty of their homes for years to come.
