uPVC Windows vs Aluminium Windows
If you’re upgrading your windows this year, you’ve probably come across two main options: aluminium and uPVC.
The main difference between aluminium and uPVC windows is the material that the window frame is manufactured from.
Both materials are popular across Leicestershire for their reliability and style, but they each offer something a little different.
To help you make the right choice for your home, let’s look at the pros and cons of each.
Pros and Cons of Aluminium and uPVC Windows
Materials and Looks
Aluminium frames are sleek, slim, and often chosen for modern homes that crave clean lines and more glass. Because aluminium is a strong metal, the frames can be thinner, letting in more natural light.
They’re also available in a wide range of finishes and colours – from bold matt black to subtle metallic tones.
uPVC, on the other hand, is a type of durable plastic that’s been a staple in British homes for decades. It’s known for its versatility and understated appearance, making it suitable for a wide variety of property styles.
While uPVC used to come mostly in white, modern manufacturing means you can now find it in woodgrain and contemporary colour finishes too.
Durability and Maintenance
Aluminium windows usually last for 40–50 years or more. They’re highly resistant to weathering and won’t rust, warp, or crack, even in extreme conditions. Maintenance is easy – a simple clean with a cloth and mild detergent keeps them looking fresh.
uPVC windows are also low maintenance and don’t need painting or regular upkeep. However, their lifespan tends to be shorter, typically 20–25 years. Over time, uPVC can fade slightly under UV exposure, although high-quality versions now include UV-resistant coatings to help prevent this.
Energy Efficiency
uPVC has traditionally been the go-to for energy-conscious homeowners. The frames have a multi-chambered design that traps heat effectively, helping to keep rooms warmer and energy bills down.
Aluminium windows used to be less efficient, but not anymore. Today’s models include advanced “thermal break” technology that significantly reduces heat loss. Combined with double or triple glazing, modern aluminium windows rival uPVC for energy efficiency.
Cost and Value
If you’re on a tighter budget, uPVC windows are generally more affordable upfront – often costing 30–40% less than aluminium.
Cost Comparison (Approximate):
- Aluminium Windows: £350 – £1,200+ per window.
- uPVC Windows: £250 – £800 per window.
That said, aluminium is a long-term investment. Because it lasts much longer and requires little repair, it often works out as a better value over time.
Sustainability and Environmental Impact
Aluminium stands out for its sustainability. It’s 100% recyclable, and reprocessing it uses only about 5% of the energy required to make new aluminium. So, when your windows eventually reach the end of their life, the material can easily be reused.
uPVC is also recyclable, but not as environmentally efficient. The recycling process is more complex, and repeated processing can degrade the material quality slightly over time.
Are uPVC or Aluminium Windows Better?
So, which is better – aluminium or uPVC windows? The truth is, there’s no right or wrong answer.
It all depends on what’s most important for you and your home:
- Choose uPVC if you want a cost-effective, energy-efficient option that suits most property styles.
- Choose aluminium if you prefer a sleek, modern look that will stand the test of time and boost your home’s value.
Generally, 85% of homeowners* in Leicestershire opt for uPVC as they are typically 30-40% less expensive than aluminium windows.
However, both materials offer excellent performance and can transform the look and feel of your property, so the “better” option really comes down to personal preference.
The most important thing is to choose an experienced, certified window installer to make sure your new windows are fitted properly and perform as they should.

FAQs
What are the main differences between aluminium and uPVC windows?
The main differences are look, performance, and cost. Aluminium windows use the strength of aluminium to give slimmer sightlines, fewer frames, and bigger glass panes, ideal for contemporary architecture. uPVC window frames and vinyl windows offer better heat transfer control and are usually the preferred option in colder climates and period properties.
What are the pros and cons of aluminium vs uPVC windows?
Aluminium windows offer exceptional durability, structural integrity, a wide range of styles, and are an environmentally friendly option with minimal maintenance, making them a great choice for busy homeowners. The main reasons people pick uPVC frames are lower cost and better insulation, but they’re bulkier and don’t last as long as aluminium.
What are the disadvantages of aluminium windows?
The key cons of aluminium windows are higher heat transfer if you choose basic frames, and a higher initial price than uPVC. Without good double glazing or thermal breaks, they can feel cooler in harsh weather conditions, particularly in stormy weather or colder climates.
How much more do aluminium windows cost than uPVC?
Aluminium windows typically cost around £150 more per window than uPVC on average, depending on size and style, with casement windows and door frames sitting higher again. You pay extra for the highly durable material, strength of aluminium and long lifespan, which can pay off over time.
Which is more expensive, aluminium or uPVC?
Aluminium windows and aluminium doors are more expensive than uPVC frames, sometimes 30-40% more for similar double glazing units. That said, their exceptional durability, minimal maintenance and long life make them an attractive option for long-term home improvements and commercial facility projects.
Are aluminium windows bad for condensation?
Modern aluminium windows aren’t “bad” for condensation, as long as they include thermal breaks and quality double glazing. Condensation is mainly about indoor moisture and temperature, not just frame material, so with the right windows and ventilation, aluminium is still an ideal choice, even in coastal areas and harsher climates.
