What Are uPVC Windows?
uPVC stands for “unplasticised polyvinyl chloride.” That’s a mouthful! Basically, it is a hard plastic used for all types of construction products like pipes, and yes, window frames.
UPVC windows have plastic frames as opposed to metal ones and have been enduringly popular over many years. Here are some key things to understand:
- uPVC windows are made from rigid, durable plastic
- They’re great at insulating houses
- Very low maintenance
- Come in many colours and finishes
- Generally less expensive than the cost of aluminium frames
uPVC Windows: Pros and Cons
| Pros | Cons |
| Strong with a long lifespan | Thicker frames mean less glass area |
| Thermally efficient to minimise heat loss for lower energy bills | They’re not as robust as aluminium |
| Excellent noise insulation | Limited frame styles |
| Weather and corrosion resistant so won’t rust, warp, or rot | May fade slightly over several years |
| Low maintenance | Are perceived as less attractive |
| More budget-friendly than aluminium | |
| Environmentally friendly and can be recycled |
Aluminium vs UPVC Windows
So which type of window frame is right for your home? The answer to this will vary depending on a few key factors.
Look and Style
Think of the age and style of your home. Aluminium windows appear more modern-day and sleek for contemporary homes whereas uPVC can give the appearance of timber and is more suitable for period homes. Both materials have a lot of choice when it comes to colour and design.
Strength and Durability
Both aluminium and uPVC windows are very tough but one of the key advantages with aluminium is that it is a longer lasting material. A top benefit of aluminium windows is that the metal won’t bend or warp, even in extreme weather. uPVC is a bit less robust but nonetheless very long lasting. It is also dent-resistant which is a problem with aluminium as it’s softer compared to other window materials.
Energy Efficiency
If saving electricity is a key priority, then uPVC definitely has the edge over aluminium window frames when it comes to keeping the heat in your home. The main drawback with aluminium windows is their greater conductivity compared to uPVC frames. However, new aluminium windows are still energy efficient.
Aluminium vs uPVC Windows: The Cost Difference
uPVC home windows are usually cheaper than aluminium windows. Expect to pay about 30-50% less on average for uPVC. Exact costs depend on the window size, any features, and your local supplier. However, despite the higher starting point for aluminium window prices, the upside is that aluminium doors and windows will increase the value of your home.
Maintenance
There’s hardly any difference in maintenance between aluminium and uPVC windows. Both just require occasional cleaning with soap and water. It’s also important to check that the moving parts are lubricated and replace the weatherstripping as needed and that’s about it!

Equipped with all the knowledge on the main differences between (and many benefits of) aluminium and uPVC windows, the question remains, how do you find the most competitive and cost-effective prices for the windows you choose for your home? Here are our top suggestions:

- One way to make your budget go further is to consider a mix of window types.

Both window types offer excellent energy efficiency and will reduce your carbon footprint.
- Look for installers that offer decent warranties to protect your investment.
- Don’t choose on price alone. Quality will also come out on top when you’re looking for trouble-free windows with a long lifespan. Cheap uPVC or aluminium windows are a false economy and won’t last or look as good in the long run.

Frequently Asked Questions
Are aluminium windows more secure than uPVC windows?
Both aluminium and uPVC windows will keep your home safe and secure. Both have integral lock systems and you can also opt for additional security features for that extra peace of mind.
Can I paint uPVC windows?
You can paint uPVC doors and windows just like wooden windows, but it’s not a good idea. These windows are pre-treated and designed to be low maintenance. Painting them can actually void your warranty. If you want a particular colour for your window frames, it’s best to buy windows in that shade rather than paint them yourself.
Do aluminium windows rust?
It’s a natural concern that metal window frames, unlike other materials, may rust. However, one of the many advantages of aluminium windows is that they are resistant to rust and corrosion and weatherproof. This makes aluminium windows a durable, long-lasting choice.
How long do uPVC windows last?
uPVC windows can last 20 to 30 years or more if you look after them and keep them in a good state of repair. They also stay looking good as well ensuring your home is smart and appealing and offers excellent thermal efficiency.
Can I combine aluminium and uPVC windows in my home?
Absolutely! You can blend aluminium and uPVC windows and any door installation and tailor designs to suit individual rooms. Powder coated aluminium windows on the front of your property provide a contemporary look with slim sightlines and a range of colour choices. Opting for uPVC window frames and glazing for a home office or bedroom offers the benefits of optimal sound reduction and thermal efficiency. Both types of windows are energy efficient and the blend can help lower cost without compromising on quality or aesthetic appeal.
