When it comes to choosing windows, opting for frames that are attractive, affordable and energy efficient is essential. There are a number of different materials widely available on the market these days, but nothing beats the addition of aluminium windows into any home. If you are looking into purchasing new frames, take a read of this article which will answer the question; why choose aluminium windows? Keep reading to find out more.

Why Choose Aluminium Windows?

There are a plethora of reasons as to why frames built from aluminium are far more superior than other materials such as uPVC or timber. To further improve the thermal efficiency of your home, take this opportunity to install either double or triple glazing glass. If your windows are more than 15 years old, the chances that they’re providing you with effective thermal insulation is highly unlikely. Later on in this article, we will run through the merits and drawbacks of both double and triple glazing. To understand why aluminium windows should be your first option we will analyse the efficiency, affordability and attractiveness of other materials.

The Benefits of Aluminium Windows

Aluminium is known for its exceptional strength and durability. Because of this, the material is notably weatherproof and won’t discolour or rust, even in the harshest of weather conditions. To further improve the durability of these window frames, you can have a powder coating layer applied that acts as a corrosion resistant. This coating also provides the frame with an attractive finish and will not require future layers of paint. Unlike timber or uPVC, aluminium doesn’t crack, rot, peel, flake, split, swell or warp over time, ensuring a long shelf-life.

Aluminium frames were once only available in a silver colour; nowadays, there is a vast variety of finishes you can choose from. You can also now opt for frames with a timber look, providing you with the ideal frame to install into traditional properties. You will also be unburdened from the demanding maintenance issues associated with wooden windows.

Aluminium window frames also require minimal maintenance, if any. Timber windows demand regular staining, treating or painting to effectively protect themselves against harsh weather conditions and maintain their condition. uPVC also requires routine cleaning to keep up appearances and remain good quality. However, aluminium frames are practically maintenance free, making them a much more desirable option. Small scratches may appear over the years but can be easily removed with a polishing agent.


When compared with uPVC frames, aluminium is far more environmentally friendly and is now widely recycled across the UK. Aluminium can be melted down, reshaped and then reformed astonishingly easily. This can be done without the material losing any of its structural integrity. By recycling just half a kilo of aluminium, you can save around 7 kWh of electricity. Because the energy needed to create these frames is much less than the cost of raw materials is, they’re the ideal option for those looking to reduce their household carbon footprint. Here is a guide on how you can recycle your aluminium window frames.

Due to the strength of this material, aluminium windows can be built using a much slimmer frame, allowing for a greater glass surface area. Because of this, these frames highly complement more modern and contemporary properties. Additionally, due to the exceptional strength of aluminium, the frames are able to holder thicker glazing, even in a thinner frame. This is ideal for those looking for maximum light in the home whilst achieving a high level of thermal insulation.

Furthermore, aluminium windows are significantly cheaper than timber frames and are guaranteed to last longer. Although they may not be as affordable as uPVC frames are, aluminium windows are more durable, require less maintenance and look far more attractive. The average cost for 15 aluminium casement windows would be between £9,350 – £10,130. The payback period on these windows is also typically shorter than alternative frames which may only provide minimal performance at a much higher cost.

Weaknesses of Aluminium Windows

The main problem with using aluminium for your window frames is that it does not hold heat well. Therefore, if you live in a cooler climate, the addition of aluminium windows into your home may not be the most appropriate idea. This can then lead to a number of condensation and frost formation problems which may cause your more trouble than its worth in the future.

However, the issue of this material not retaining heat effectively can be resolved. Through the addition of a non-conductive material between the two panes, you can significantly improve the thermal efficiency of aluminium window frames. There must be a complete break between the two aluminium parts to prevent a thermal bridge from establishing and causing you to lose heat. With the addition of this, aluminium frames can easily achieve improvements in heat gain and reduced heat loss by almost 60% which rivals more expensive equivalents such as uPVC or timber.

Opting For Improved Glazing Options

If you are going to replace your existing windows with new and improved aluminium frames, you may as well take this opportunity to improve the current glazing situation. All new builds now in the UK come with double glazing glass incorporated into the windows, however, if you own an older property, it may only contain single glazed glass. A significant amount of heat is lost through poorly performing window glass. In addition to this, you may be noticing cold spots and draughts entering your home through the windows. The best way to eliminate this problem is to invest in either double or triple glazed glass, along with thermally insulating frames.


Overall, hopefully, you are now aware of all the major benefits aluminium window frames has to offer. From improving the thermal efficiency of your home to being more environmentally friendly, there are a number of advantages that should help you come to a conclusion.
