uPVC (unplasticised polyvinyl chloride) has revolutionised the window and door industry due to its impressive durability, low maintenance, and energy-efficient properties. However, one common concern that often arises when considering coloured uPVC windows and doors is whether they fade over time. In this blog, we will explore the factors influencing uPVC colour fading and separate fact from fiction to help you make informed decisions for your home.
Understanding uPVC and Colour Technology
uPVC is a synthetic material known for its exceptional resistance to weathering, making it a popular choice for outdoor applications. It undergoes a unique manufacturing process, where pigments are mixed with the uPVC material before being extruded into profiles, resulting in coloured uPVC products. The colourants are designed to be UV resistant to mitigate fading caused by prolonged sun exposure.
Fact or Fiction: Does Coloured uPVC Fade?
Fact – uPVC is UV resistant – In general, coloured uPVC is engineered to be UV resistant, reducing the likelihood of fading. Modern manufacturing techniques and advancements in pigment technology have significantly improved the colour retention of uPVC products.
Fiction – Coloured uPVC Never Fades – While the colour retention of uPVC is impressive, claiming it never fades would be inaccurate. All materials, including uPVC, are subject to some degree of weathering over time. However, the extent of fading depends on various factors.
Factors Influencing uPVC Colour Fading
UV Exposure
The primary cause of colour fading in uPVC is prolonged exposure to ultraviolet (UV) rays from the sun. Regions with intense sunlight and extreme temperatures may experience slightly more fading milder climates.
Quality of uPVC
The quality of the uPVC material and the pigments used during the manufacturing process significantly impact colour retention. High-quality uPVC with UV-stable pigments will fare better in retaining their colour over time.
Maintenance
Proper maintenance and cleaning of coloured uPVC windows and doors can help preserve their appearance. Regular washing away dirt, dust, and debris can prevent build-up, reducing the risk of fading.
Environmental Pollution
Airborne pollutants can settle on uPVC surfaces, leading to a dull appearance over time. Homes located in heavily polluted areas might experience more noticeable fading due to this factor.
Quality of Installation
Proper installation by experienced professionals ensures that the uPVC products are appropriately sealed and protected for their longevity.
Conclusion
Coloured uPVC windows and doors offer an excellent option for homeowners seeking aesthetics, durability, and energy efficiency. While it’s true that all materials may experience some degree of fading over time, high-quality uPVC products with UV-resistant pigments are designed to withstand the test of time and retain their vibrant colours for years.
When choosing coloured uPVC, it’s essential to opt for reputable manufacturers known for using top-grade materials and advanced pigment technology. Regular maintenance and cleaning also play a crucial role in preserving the appearance of uPVC products.
