Aluminium windows have pros and cons, and it’s important that you understand what they offer and if they meet your needs. Your most pressing question is probably, how much do aluminium windows cost.
Cost of Aluminium Windows
Aluminum windows are the second most expensive glazing frame available, with the first being wood or timber. Aluminium frames are more expensive to manufacture, but provide strength and durability, which is often worth the premium price. In most cases, you will pay a median of £550 per window, or an average cost of £500-605 for a standard 60 x 80 cm casement window. This cost will increase exponentially if you choose more complex frames.
You can expect the following average costs for aluminium windows.
|Casement||Sash||Tilt & Turn|
|60 x 90||£500-605||£1000-2010||£800-1,350|
|90 x 120||£655-735||£1,300-£2432||£1048-£1633|
|120 x 120||£770 – 875||£1521-£2,942||£1226-£1978|
In most cases, double glazing costs are divided into four categories:
- Frame – Frames are typically the most expensive part of new windows because they must be cut to fit an existing opening, fitted well, and sealed to prevent air leakage.
- Glass – The actual glazing will vary in cost depending on whether you choose a standard glass, Low E or other coating,
- Fitting – Actual fitting costs, which are determined by your home.
- Energy Efficiency – The total combination of energy saving measures applied to the window. The more energy efficient the window, the more it will cost.
Aluminium Frames vs Other Frames
Aluminium frames cost more than other materials such as composite or uPVC, but less than wood and other similar frames.
|Material||60 x 90||90 x 120||120 x 120|
|Aluminium||£500-605||£655-735||£770 – 875|
|Wood||£845 – £910||£1,245 – 1,300||£1,365 -1,405|
Aluminum windows do cost considerably more at about 50-70% more than uPVC, but they are a popular architects choice for replacing traditional windows, creating a modern look, and replacing old windows with long-lasting frames.
Now that you know how much aluminium frames are likely to cost, you’re probably concerned about energy efficiency.
Most of us buy replacement windows to improve energy efficiency to cut costs on heating and cooling. Unfortunately, aluminium windows are not the most energy efficient option you can choose. Aluminium is a heat conductive material.
However, many modern aluminium windows feature thermal breaks, insulation, and multi-compartment frames, which prevent heat from escaping. While not all aluminium windows will offer these features, you can check the energy efficiency of your windows by checking the WER rating.
WER Rating – The WER Rating or Window Energy Rating is the listed A++ to E rating found on many windows. British law mandates that you cannot install windows with a WER rating of less than C. Most aluminium windows feature a rating of C to A.
U-Value – U value measures heat transference or insulating properties. The lower the U-Value, the more efficient the window.
Pros and Cons of Aluminium Windows
Aluminium windows offer a lot of pros and cons, and you should consider them when choosing replacement windows for your home.
- Aluminium doors and windows are very light and durable
- Strong and suitable for large windows
- Require minimal care
- Available in dozens of colours and styles
- Average lifespan of 30+ years
- Very secure and compatible with 3-point locking systems
- More expensive than some other options
- Not available in every style
- Less energy efficient than cheaper uPVC frames
- Don’t add the same value as wood frames
In most cases, the only real cons of aluminium windows are that they cost more than uPVC and don’t offer the same thermal resistance without thermal breaks. However, most manufacturers now include thermal breaks as a standard practice.
Styles and Colours
Aluminium frames offer a significant advantage over styles like wood and uPVC in that they are easy to powder coat and finish. As a result, many manufacturers offer anywhere from 20 to several hundred different frame colours for you to choose, including natural wood and whitewash styles. This allows you to design your house based on hundreds of colour options.
In most cases, you can also purchase aluminium frames in casement, sash, tilt & turn, French, and sometimes other styles.
Who Offers Aluminium Windows?
While aluminium windows are a popular choice, they are less common than wood, uPVC, or composite. This means that you may have fewer choices when you go to choose an installer. In fact, of the top 5 double glazing installers in the UK, only two offer aluminium windows.
In short, while you can find aluminium frames, they are less common than other options, and you may have difficulty finding a specific installer. However, Anglian and Everest, two of the best double glazing installers in the UK offer aluminium window, as do many quality local installers.
