UPVC vs Aluminium Windows

20th March 2024 |


Aluminium Bifold DoorsInvesting in new windows for your home can be a significant outlay, so making sure you find the right material for your window frames will be one of the biggest decisions you’ll need to make. Your final choice will depend on your taste, how the windows will look in your home, and the qualities they can bring. But are aluminium windows better than uPVC?

Aluminium or uPVC windows?

Both aluminium and uPVC windows have distinct features and unique benefits which is why they’re both a popular – as well as common – frame choice for homeowners up and down the country. But perhaps because of these distinct features and benefits, it can be difficult to know which material will be best suited to your home.

As Majestic Designs’ technology has, and continues to evolve, there’s no doubt that both our aluminium and uPVC frames give you more choice for superior, energy-efficient windows than ever before. But we’ve taken the benefits of each material and broken them down into bite-sized chunks to help you make a better and more informed decision.

The benefits of uPVC windows

When you’re looking to replace the windows in your home, your first thoughts might go towards uPVC frames before anything else. With exceptional energy-efficiency and classic good looks, it’s not hard to understand why. But here are some additional benefits to why uPVC windows might be the right choice for you.

Low maintenance

uPVC double glazed window frames have a solid working life of up to 20 years, giving you a sound return on your investment. Without the downsides of rotting, warping, or swelling in extreme weather like wooden frames, uPVC is durable and needs very little maintenance – other than a quick clean and some lubrication on the hinges from time to time.

Colour choice

While white was once the only colour option for uPVC windows, now you have a wide choice of hard-wearing frame colours to suit your property and your taste. There are even wood grain finishes for a touch of classic authenticity. Best of all, the colours and finishes are resilient, so won’t crack, peel, or fade over time.

Natural insulation

uPVC is a naturally warm frame material and insulator, and together with a five-chamber internal profile, uPVC helps increase thermal performance. So while that helps you to keep heat inside and reduce your energy bills, it also helps reduce outside noise too.

Lightweight material

Together with being thermally efficient, uPVC is also a lightweight frame material for window frames, making them easy and quick to install. It’s also a sustainable material, so your older frames can be recycled many times over without any molecular degradation.

100% Guaranteed

Every uPVC window from Majestic Designs comes with a full 100% guarantee for 10-years, giving you long-term peace of mind that, should anything go wrong, we’ll replace or repair any window without costing you a penny


With the material cost of uPVC less prone to price fluctuation, choosing uPVC can give you a considerable cost saving compared to aluminium frames. That could be something to bear in mind if you’re working to a budget or need more windows fitted.

Aluminium Bifold DoorsThe benefits of aluminium windows

With all the good things going for uPVC, you could be forgiven for thinking that there’s no contest between that and aluminium. But aluminium frames also come with a whole set of amazing benefits. Alongside their increasing popularity, their long-lasting stability, durability, and style, as an option, aluminium can always make you look twice.

Superior strength

As a base material, aluminium frames have a much higher compound strength than uPVC. This means they can give you the option of having larger windows but with a slimmer profile. Fantastic for a larger ‘wall of glass’ for uninterrupted views outside.


Whether your aluminium frames are black or you choose a specific colour, having them coated with a layer of dry powder before they’re heat-treated will give them a hard-wearing and long-lasting finish that’s scratch-resistant, non-fading, and low maintenance.

Environmentally friendly

Aluminium is a relatively low-cost material, but it’s also one of the most environmentally-friendly metals available. Plus, as the most recyclable of industrial metals, it can be recycled to create new aluminium without any breakdown of strength.


Aluminium frames come pre-fitted with a polyamide ‘thermal break’ which is additional insulation inside the frame. This helps reduce both condensation and the transfer of heat energy, so less heat is lost and you save money on your energy bills.


The life of aluminium window frames can be up to 30 years. Thanks to the stability and durability of the material, aluminium frames are incredibly tough and long-lasting, making them capable of withstanding even the most extreme of weathers and temperatures.

Long-term investment

Though aluminium frames can be more expensive than uPVC and be at the top end of your budget, their credentials speak for themselves. Perfect for more contemporary, modern homes, the investment in aluminium frames can more than pay off in the long-term.

There are various pros of uPVC windows that explain why so many homeowners choose uPVC for their projects. For those working to a budget, uPVC windows offer a cost-effective solution that’s especially ideal for larger installations. Additionally, uPVC’s excellent insulating properties make it an attractive choice for those looking to reduce their energy bills or with homes in noisy environments.

For some homeowners, the low maintenance, thermal efficiency, and cost-effectiveness of uPVC windows outweighs the cons of potential discoloration and the material’s non-biodegradability. However, some homeowners find the bulkier appearance of uPVC less appealing compared to the sleek, minimalist design of aluminium frames. Therefore, when considering uPVC over aluminium windows, it’s essential to weigh these pros and cons against your needs and aesthetic preferences.

Yes, aluminium windows generally offer better durability compared to uPVC. As uPVC windows are made from plastic, they have a much shorter lifespan than aluminium and are prone to discolouration and sagging over time. Aluminium, however, is known for its inherent strength and resistance to wear and tear, making it a more robust and longer-lasting material than uPVC.


Yes, aluminium windows do tend to be more expensive than uPVC. However, the exact cost comparison between aluminium and uPVC windows depends on various factors, such as the size, style, and quantity of windows required for your project.

While aluminium windows may have a higher upfront cost, they often prove to be cost-effective in the long term because it’s a more robust and longer-lasting material than uPVC.


Both uPVC and aluminium windows offer a wide range of design options to suit various architectural styles and preferences.

You can also choose from various styles such as sliding, tilt and turn, sash, or casement windows.
