Aluminium vs uPVC windows: Which has better long term value?

If you’re considering new windows for your home, you’ll likely come across two common options: aluminium and uPVC window style. Both offer excellent performance in the right setting, but when it comes to long term value, how do they compare?
At E&A Windows, we supply and install both typical casement aluminium window frames and uPVC windows across Hertfordshire, Essex, North London and beyond. Our aim is always to help you find the best window solution for your home, budget and future plans.
This guide breaks down the key differences between aluminium vs uPVC windows to help you make the right choice.
Durability: which window lasts longer?
Aluminium frames are known as a highly durable material, outlasting uPVC window frames by many years. With proper installation and care, they can last 40 years or more, demonstrating the significant benefits of aluminium windows. They’re also more resistant to warping and UV damage, making them ideal for modern homes or properties exposed to the elements.
uPVC windows typically offer a lifespan of around 20 to 30 years. While still a durable material, uPVC can be more prone to discolouration over time, especially on south-facing elevations.
Maintenance and care
If you’re looking for low maintenance, both materials score well. uPVC frames need little more than a bucket of warm soapy water every few months. The same goes for aluminium window frames, which also resist corrosion and don’t flake or peel, unlike wooden windows that may require more attention.
One key difference is appearance over time. uPVC window frames may fade when exposed to direct sunlight, especially white finishes, whereas powder-coated aluminium retains its colour with minimal upkeep. At E&A Windows, our aluminium range is available in a wide range of colours, including dual-colour options, offering a more robust finish in the long run.
Thermal performance and energy bills
When comparing uPVC vs aluminium, energy efficiency is often a top priority. Modern aluminium windows include an aluminium thermal break – an insulating barrier inside the frame that significantly improves their performance and heat retention. Combined with double glazing or triple glazing, they achieve excellent U-values that compete closely with uPVC.
uPVC windows are naturally more insulating due to the material’s properties, which can make them slightly more efficient in some cases. However, with high-spec aluminium casement windows, which come in a huge variety of styles, the energy efficiency gap has narrowed significantly.
At E&A Windows, we offer energy-efficient solutions across both materials, so whichever you choose, you’ll see savings on your energy bills over time.
Aesthetics and style options
What looks better – aluminium or uPVC? That depends on your type of building and the type of material you choose.
Aluminium frames have slim sightlines and a clean, modern finish that suits contemporary homes and large glazed areas. The aesthetics of aluminium make it a top choice for high-end builds or urban properties where sharp lines and style matter.
uPVC frames, on the other hand, are often used for period properties, traditional homes, or where budget is a key factor. Our uPVC range includes flush sash windows, sash windows and casement windows in a range of styles and colours, so you can still achieve a classic or modern look.
We also offer uPVC doors and aluminium doors to match, giving your whole home a consistent and stylish appearance.
Security and strength
When it comes to home security, both aluminium and uPVC windows offer robust performance. At E&A Windows, all our new windows come with secure multi-point locking systems as standard, giving you peace of mind against potential intruders no matter which material you choose.
Aluminium window frames have a natural strength that makes them harder to force or bend. This makes them ideal for large glazing units or ground floor openings where added protection and thermal conductivity are important.
uPVC window frames are reinforced internally to improve structural integrity, offering reliable strength across most types of windows, including casement and sash windows.
Sustainability and environmental impact
More homeowners are thinking about the environmental impact of their home improvements – and your choice of window frame can play a role. uPVC is a recyclable material that can withstand harsh weather conditions and has improved in terms of sustainability in recent years, but its production does rely on fossil fuels.
Aluminium, on the other hand, is infinitely recyclable without losing quality. This makes it a strong contender for anyone considering greener building materials for a modern home or renovation project.
Cost and long-term value
In terms of manufacturing costs, uPVC is a popular choice as it is more affordable. That means a lower upfront price – perfect if you’re replacing several types of windows at once. However, aluminium provides better value over time due to its highly durable material, longevity and lower likelihood of needing repairs or replacement.
If you’re staying in your home for a long time, aluminium may offer better long term value, while uPVC is a reliable and cost-effective option that may be a step in the right direction for those on a tighter budget or looking to renovate for resale.
Comparing window frame materials: aluminium vs uPVC
Aluminium windows offer a highly durable material that withstands harsh weather conditions, making them a long-lasting choice. In contrast, uPVC windows, made from unplasticized polyvinyl chloride, provide excellent thermal efficiency with low maintenance requirements. While both materials provide good thermal insulation, aluminium frames can allow for larger window styles and stylish designs that appeal to modern aesthetics. Conversely, uPVC frames are often favored for their energy efficiency and ease of care, with minimal upkeep needed throughout their lifespan.
Finish options for aluminium and uPVC windows
Aluminium and uPVC windows both offer unique finish options that cater to diverse aesthetic preferences. Typically, aluminium frames come in a range of powder-coated finishes, allowing for vibrant colors and sleek designs. Conversely, uPVC windows often feature smooth, clean surfaces, easily painted or laminated to achieve various styles. This versatility enhances the appeal of both materials while accommodating different home designs. Choosing the right finish can significantly impact the overall look, performance, and longevity of your windows.
Aluminium vs uPVC windows: Which is better for your home?
There’s little difference in everyday performance when comparing modern, high-quality options. Both options offer great security, insulation, and appearance. Your decision may come down to your budget, the type of window types, or type of building.
For modern homes or design-led projects, aluminium stands out. For traditional properties or value-led renovations, uPVC remains a brilliant material with a strong track record.
