Which windows are better, uPVC or aluminium?
Wednesday, 21 April 2021
When selecting new double glazed or even triple glazed windows for a property, it can be an easy assumption that uPVC is the natural option. Indeed it’s a material which is very popular now across the windows and doors of residential properties. Despite this, aluminium is an extremely efficient and attractive material for a window system. When is it the better solution, though? And how can you define which window material is better, uPVC or aluminium? We’ll look at the features of both materials, which situations each window material fits aesthetically, and how to decide between the two options.
Alternatives to Timber
Both uPVC and aluminium window systems have developed as more durable and less high maintenance alternatives to timber. In some instances, for example strict conservation restrictions, timber frames are still used. However, in many cases, home or property owners seek to reduce maintenance by replicating the appearance of wood through wood replacement uPVC products. This balances the authentic visual appeal of wood with increased durability of the material.
Features of uPVC Windows
What are the benefits of choosing a uPVC window system, then? The range of products made by this material are huge, but all systems share some key features that make them an excellent material for double and triple glazed windows.
Durable
Once you have fitted your home with uPVC windows, they should last and last. Obviously, the expected lifespan of a product depends on the quality of system that you select, and the maintenance care that you give to working parts like hinges and latches. Modern uPVC products, though, can be expected to last anywhere up to 30 years.
Low Cost
Again, this is comparative and very much depends on the specific system that you choose. For example, more specified products like the Residence 9 series carry a higher price tag. However, overall there is normally a uPVC double glazed option to fit most budgets.
High Performance
uPVC windows will withstand periods of extreme weather, and do not warp in the way that timber frames of old would. The engineering of uPVC has improved still further since early models, to make this material extremely high performing in protecting your home from the elements.
Range of Aesthetic
From a modern flush style to more period sculptured features, window systems made from uPVC cover a multitude of design concepts. The colours that this material is available in have increased in recent years to include heritage shades, so that white is no longer your only option.
Security
The structure of uPVC casements is high security, as they are extremely hard to break through or damage to enter a property.
Features of Aluminium Windows
Perhaps a lesser known domestic option, you may be more used to seeing aluminium framed windows in commercial properties. However, these double and triple glazed window systems are rising in popularity. Looking at the features below, it’s easy to see why.
Low Maintenance
Aluminium does not need regular treatment like timber frames. While the materials of the past may have been prone to rust, modern aluminium systems are resistant to corrosion, making this the lowest maintenance material you can choose for your windows. As the frame is slimmer than uPVC options, there are fewer nooks and crannies where grime can settle.
Durable
Aluminium has a very high strength to weight ratio, and can last for as long as 45 years. This makes it the most durable option for a window system.
Sustainable
The durability of aluminium is one part of why it is such a sustainable choice. Another is the energy standard of these windows. As the thermal performance is so high, double and triple glazed aluminium windows offer the lowest U-values. On the flip side of this material’s durability is the fact that aluminium is 100% recyclable. So at the end of its life, an aluminium window system can be expected to be recycled, using just 5% of the energy that it takes to create primary aluminium.
Contemporary
One of the reasons that aluminium has risen in popularity is its contemporary style. With slim frames and larger glass area, these windows bring a popular minimalist style. The powder coated finishing can be matched to any RAL colour you may wish. This gives aluminium systems a wonderful flexibility when it comes to architectural concepts.
High Performance
Aluminium framed windows perform extremely well when it comes to insulation. This is down to the thermal breaks within the aluminium frame. This not only means that your home loses less heat from the inside out, but also that your space does not over heat in hot Summer months.
uPVC Style
Which buildings might best suit uPVC double or triple glazed windows, then? Well, it depends on the final user! However, as a guide we find that period properties that will benefit from a timber replacement aesthetic will work great with heritage uPVC systems. While maintaining performance with a low key and flexible look can be achieved through clean and unfussy uPVC glazing.
Aluminium Style
When do we find aluminium as the best window solution? This material is already popular for modern, industrial, and even barn conversion property styles. It achieves a retro Crittall look fantastically well, so is rising in popularity in this market too. If budget can be found, aluminium is definitely one to consider for many aesthetic concepts.
The Cost Comparison
Fitting into a budget is a consideration which comes up frequently, and at first glance it is always the most essential of uPVC window systems which will fit into a strict budget. However, when we look at the benefits of these two window materials, we should consider value in a broader sense. Would it make sense in the long term, for example, to redirect budget from other areas to afford aluminium windows which will last considerably longer? Or perhaps the period harmony offered by a range like Residence 9 brings far higher value to your home overall. Comparing cost can therefore become complicated.
