When it comes to choosing new windows for your home, longevity is often high on the priority list. Whether you’re updating your Nottingham terrace, modernising a property in Leicester or renovating a family home in Derby, aluminium windows are a smart investment.
But just how long can you expect them to last? In this guide, we’ll explore the lifespan of aluminium windows, how they compare to uPVC and timber alternatives, and what factors influence their long-term durability.
The typical lifespan of aluminium windows
With proper care, modern aluminium window frames can last anywhere between 30 to 45 years – and in many cases, even longer. That’s significantly higher than the average lifespan of uPVC windows (20 to 30 years) and timber (15 to 25 years without regular treatment).
Why the difference? It largely comes down to inherent strength, corrosion resistance and the low maintenance requirements of aluminium.
Excellent durability: Why aluminium windows last so long
Aluminium is naturally resistant to corrosion, especially when treated with powder coating – a tough, coloured finish that protects the surface from the elements. This protective layer means that aluminium frames can stand up to harsh weather conditions without warping, cracking or rotting.
Add in strong structural integrity and you’ve got one of the most durable materials available for window frames.
How does aluminium compare to uPVC and timber?
| Material | Lifespan | Maintenance | Durability |
| Aluminium | 30–45+ years | Very low | Excellent |
| uPVC | 20–30 years | Low | Good |
| Timber | 15–25 years | High | Variable |
uPVC windows are still a popular choice, especially for budget-conscious homeowners. But aluminium offers a long lifespan with a more slimline profile, allowing for panoramic views and maximum natural light – ideal for modern housing design.
What affects the longevity of aluminium windows?
Several factors can impact the lifespan of aluminium windows, including:
- Powder coating quality: A high-quality finish resists fading and flaking.
- Installation: Poor installation can reduce performance and lead to issues like condensation or draughts.
- Location: Coastal areas may expose frames to salt, which requires more frequent regular cleaning.
- Maintenance: Though minimal, occasional cleaning and inspection helps retain energy efficiency and appearance.
Are aluminium windows low maintenance?
Yes, very. One of the key benefits of choosing aluminium window frames is their low maintenance. They don’t need painting or varnishing, and a quick clean with warm soapy water every few months is usually enough to keep them looking their best.
Do aluminium windows help reduce energy bills?
Absolutely. Thanks to high thermal performance, modern double glazing units with aluminium frames can significantly reduce energy bills. At The Nottingham Window Company, all of our aluminium windows come with A+ rated glass, helping you retain heat and cut down on heat loss.
What are the signs it’s time to replace your windows?
Look out for:
- Persistent condensation between glazing panes
- Difficulty opening or closing
- Cold draughts or rising energy bills
- Visible damage or warping
If your windows are showing any of these signs, replacing them with modern aluminium windows can be a long-term solution.
What types of aluminium windows are available?
At The Nottingham Window Company, we supply and install a range of aluminium windows, including:
- Casement windows – the UK’s most common style, ideal for all property types
- Tilt and turn windows – versatile and great for ventilation
- Fixed and shaped windows – for unique architectural designs
Our aluminium window frames are available in a variety of styles and colours, all manufactured using the latest thermal break technology for maximum energy efficiency.
Can tilt and turn aluminium windows improve safety?
Yes. The tilt function allows secure ventilation without fully opening the window, while the turn option provides a wide opening for easy cleaning or emergency exit – perfect for upstairs rooms or conservatories.
How to extend the lifespan of your windows
To get the longest lifespan of your aluminium windows, we recommend:
- Cleaning the frames and glass at least twice a year
- Checking for signs of wear around seals and joints
- Avoiding harsh chemical cleaners
- Booking professional servicing if you notice issues
These small steps help your windows stand the test of time.
