Factors Impacting the Cost of UPVC vs. Aluminium Windows

The cost of UPVC and aluminium windows can be influenced by several factors, such as the material cost, manufacturing cost, availability, and maintenance expenses.

Material cost

Aluminium costs more than uPVC. This is why windows made of aluminium cost more. One reason for this is that it takes a lot to make aluminium frames. More than what’s needed for uPVC frames.

Because not all window makers keep these, you might end up having to pay more if you choose them. On average, people spend 30% to 40% more on aluminium windows than uPVC ones.

Even though the price sounds high, don’t think that just because uPVC is cheaper, it doesn’t last as long or work as well.

Manufacturing cost

The manufacturing cost of aluminum windows is higher compared to uPVC windows. This is because the material itself is more expensive, which contributes to the overall cost. Aluminium window frames require complex manufacturing processes, including cutting, welding, and finishing.

These additional steps increase the production costs further. On the other hand, uPVC windows are relatively easier and cheaper to manufacture due to their simpler production process.

As a result, uPVC windows are generally more affordable than aluminium windows in terms of manufacturing costs.

In addition to the higher material cost and complex manufacturing process, there may also be limitations on availability when it comes to aluminium windows. Not all window fitters may offer aluminium options or have expertise in installing them due to these factors.


It’s important to consider the availability of window options when comparing the cost of aluminium windows and uPVC. While uPVC windows are more widely available and can be purchased from various suppliers, it may not be as easy to find aluminium windows in every shop or from every window fitter.

This limited availability of aluminium windows can sometimes make them a bit harder to come by compared to uPVC options. Despite this, there are still plenty of places where you can find aluminium windows if that’s what you prefer for your home.

Maintenance cost

Maintaining windows is an important factor to consider when comparing the cost of aluminium and uPVC windows. It’s worth noting that both types require some level of maintenance, although the extent may vary.

Aluminium windows are generally more durable and require minimal maintenance over their lifespan. They are resistant to rust, rot, and corrosion. On the other hand, uPVC windows are also low-maintenance but may require occasional cleaning to keep them looking their best.

Regular cleaning with soapy water is usually sufficient for uPVC frames. Overall, while uPVC may require slightly more maintenance than aluminium, both options offer relatively hassle-free upkeep in the long run.

Advantages and Disadvantages of Aluminium and UPVC Windows

Aluminium windows offer exceptional strength and durability, making them perfect for areas with harsh weather conditions. On the other hand, UPVC windows are known for their affordability and low maintenance requirements.

Aluminium: Advantages

Aluminium windows have several advantages that make them a popular choice for homeowners. Firstly, they are incredibly durable and long-lasting. Aluminium is a strong material that can withstand harsh weather conditions without warping or deteriorating.

This means that once you install aluminium windows, you can expect them to last for many years without needing frequent repairs or replacements.

Secondly, aluminium windows offer excellent security. The material is very sturdy and difficult to break, making it an effective deterrent against intruders. Additionally, aluminium frames can be fitted with advanced locking mechanisms to enhance home security even further.

Another advantage of aluminium windows is their slim profile. Unlike some other types of window frames, aluminium frames are sleek and thin, allowing for larger glass panels and unobstructed views outside.

This makes them a great option if you want to maximise natural light in your home and create a more spacious feel in your living areas.

Aluminium: Disadvantages

Aluminium windows have some disadvantages that homeowners should consider. One of the main drawbacks is their higher cost compared to uPVC windows, with an average price difference of around €150 in Ireland.

This higher cost primarily stems from the more expensive aluminium material itself. Additionally, manufacturing and installation expenses for aluminium windows tend to be higher than those for uPVC windows.

While there are competitive options available for cheaper aluminium windows, on average, they still remain 30% to 40% more expensive than uPVC alternatives. However, it’s important to note that these disadvantages don’t mean lower quality; it’s just a matter of affordability when considering window options.

UPVC: Advantages

UPVC windows have several advantages over aluminium windows. Firstly, they are more cost-effective, making them a more affordable option for homeowners. Despite being cheaper, UPVC windows can still offer good quality and durability.

They also require less maintenance compared to aluminium windows, which may need regular repainting or treatment. Another advantage of UPVC is that it is a good insulator, helping to keep your home warm and reducing energy costs.

Additionally, UPVC windows are available in various styles and designs to suit different preferences and architectural needs. Whether you’re renovating an existing property or building your dream coastal home, these versatile windows can complement the aesthetics seamlessly.

UPVC: Disadvantages

UPVC windows, while cost-effective, do have some disadvantages to consider. One drawback is that UPVC frames may not be as visually appealing as aluminium frames. Additionally, UPVC windows can expand and contract in extreme temperatures, potentially leading to warping or cracking over time.

Another disadvantage is that UPVC windows have a shorter lifespan compared to aluminium windows. Furthermore, UPVC is not as strong as aluminum, making it more susceptible to break-ins or damage.

Although these are the disadvantages of UPVC windows, it’s important to remember that they still offer affordability and durability for homeowners in Ireland.

In The End!

It is clear that the cost of aluminium windows is higher than that of UPVC windows. Although uPVC windows are generally more affordable and cost-effective, it’s important to consider specific needs and preferences when choosing between the two.

While aluminum may be more expensive, it offers certain advantages, such as durability and longevity. Ultimately, homeowners should evaluate their budget and priorities to determine which option provides the best value for money.
