Aluminium window frames are mostly used when people are looking to install newer-styled window frames that are not made of wood.

uPVC windows, also known as Unplasticized Polyvinyl Chloride, are an alternative to using aluminium windows. This is a low-maintenance material that is used on window frames and sills as a substitute to painted wood.

But are aluminium windows the better investment? Let’s discuss this further.

What’s the Difference Between uPVC and Aluminium Windows?

Both window frames are a good option and have great benefits. Let’s weigh out the pros and cons of each to determine how different they are. Here are some key benefits of uPVC windows vs aluminium windows.

Aluminium windows

Aluminium windows are a better option as they usually allow for a larger glass surface area, which allows more natural light into the space. They also have slim sightlines, which means that they may use limited amounts of space.

They are stronger and more durable, as the material they are made from is highly resistant to rust and other weather elements. They also have a long lifespan which means that they can be used for at least 30+ years after installation.

Double-glazed aluminium windows are energy efficient – they can lower the cost of energy bills as the double-glazing traps heat by insulating the area between the glass panes. It is an attractive material, they have a modern design that can be incorporated into any home and design, giving you a contemporary feel.


  • Low maintenance
  • Long lifespan
  • Slim design features
  • Strongest material
  • Super thermal performances
  • More design and colour options
  • Environmentally friendly
  • Weatherproof and waterproof


  • Hardware maintenance such as replacing the screws that hold the frame in place
  • More expensive to install

uPVC windows

uPVC window frames have the option of being double-glazed or triple-glazed. This means that not only do they have thermal efficiency, but they also reduce noise pollution. They also have multi-point locking systems which ensure safety.

However, these window frames are less durable; they do not last as long as aluminium frames. They also have a limited design choice and also have a much thicker frame when compared to the sleek design of the aluminium frames.

Although timber windows being cheaper than aluminium windows can be a common misconception, as aluminium windows are cheaper, as well as have lower long-term costs.

Modern uPVC windows are much cheaper to install than aluminium windows. There are so many factors that contribute to the cost of using aluminium windows. These include but are not limited to:

  • The number of window panes
  • If they are double or triple glazed
  • The colour or design you want
  • The size of the window

However, aluminium windows are more cost-effective in the long term than installing uPVC frames. Since aluminium windows are becoming the more popular choice, the cost of them has reduced significantly, as they are now more readily available.

Are Aluminium Windows Good?

Aluminium windows are a good choice as they are most cost-effective in the long run. They have thermal breaks, keeping heat in a room without having it escape despite the cold touch to the aluminium. This makes them environmentally friendly.

They are easy to maintain and do not require a lot of effort aside from the occasional wipe-down and checking of the screws that hold them in place. Their reinforced frames make them secure and also help prevent heat loss.

Different Styles and Designs of Aluminium Windows

There are different design styles and to choose from when wanting to install aluminium windows.

First of all, casement window frames; these window frames swing out when opening. They can be hung from the side or the top and are a great option for control, especially with the weather elements.

A stacking window frame is also a style of frame that looks as though the window is folded. These new windows allow for more light to come into an area than uPVC ones. These windows are designed to look like doors but have a smaller dimension.

Fixed window panes can be used in a conservation area where you do not need to have a window open.

Sliding windows are another design that can be used for a stylish and modern look in your home.

The most popular choices of colours are charcoal, black, silver, bronze, and white. These are standard powder-coated paint options. In some instances, people want to know: Can you paint powder-coated aluminium windows? Click on the link to see the advice and tips on how you can do that!
