Aluminium vs uPVC Roof Lantern


When considering ways to brighten your home with natural light, roof lanterns are a standout choice. They look amazing and invite an abundance of sunlight into your home. However, some homeowners need help deciding which material they should choose for their roof lanterns: aluminium or uPVC?

Overall, aluminium is more suitable, and here’s why.

Benefits of Aluminium Roof Lanterns

Aluminium roof lanterns are increasingly popular for their exceptional benefits for aesthetics and functionality. Here’s why they stand out:



Aluminium is renowned for its strength and longevity. Unlike other materials that might degrade or distort under extreme weather conditions, aluminium maintains its integrity for years.


Slimline Profile

One of the most striking features of aluminium roof lanterns is their slimline profile. This design looks modern and sleek while maximising the glass area, which allows for more natural light to enter your space without the obstruction of bulky frames.


Low Maintenance

Aluminium is naturally resistant to corrosion, which means it doesn’t rust or require frequent repainting. This low maintenance quality ensures that your roof lantern remains looking new with minimal effort, saving you time and money in the long run.



Aluminium can be powder-coated to suit your colour requirements. We currently offer Grey/White, Grey/Grey and Black/Black so you can be sure the lantern matches the interior and exterior design.


Benefits of uPVC Roof Lanterns

uPVC roof lanterns offer their own advantages, but these are generally limited to weight and cost:



uPVC is significantly lighter than many other materials, which can simplify the installation process.


Cheaper to Build

For those on a tight budget, uPVC roof lanterns generally cost less to manufacture and install. This affordability makes uPVC an appealing option.


However, this doesn’t necessarily make them a better option.


Aluminium vs uPVC Roof Lanterns: How Do They Compare?

Aluminium is the optimal choice for roof lanterns, excelling not just in functionality but also in style and longevity. Its refined slimline design elegantly complements any architectural style while maximising the influx of natural light.

Beyond aesthetics, aluminium is celebrated for its robustness and ability to withstand the elements without succumbing to corrosion. Its minimal upkeep and the ability to tailor its colour to fit any decor make it an undeniably versatile and practical option, ensuring that your investment not only lasts but remains as striking and efficient as the day it was installed.

While uPVC roof lanterns are initially more affordable, they often fall short in longevity and aesthetic preservation compared to their aluminium counterparts. Over time, uPVC can be prone to warping and discolouration when exposed to sunlight, compromising the look and integrity of the structure.

Additionally, uPVC frames typically have bulkier sightlines which can detract from the sleek, clean design many homeowners prefer. This not only impacts the amount of natural light that can enter but also affects the overall visual appeal of the roof lantern, making it less ideal for those seeking a long-term, durable solution in their home design.



While both aluminium and uPVC roof lanterns have their advantages, the choice becomes clear when considering durability, aesthetics and overall value. Aluminium is a superior material for roof lanterns, offering durability, a sleek slimline profile, minimal maintenance and extensive customisability.

Although uPVC might initially appeal due to its lower cost and lightweight properties, it falls short in terms of longevity and visual appeal over time. Choosing an aluminium roof lantern from Daylight Systems ensures a lasting investment that enhances your home's natural light and aesthetic value, making it a clear winner in the long run.



Which is better, uPVC or aluminium?

Aluminium is generally considered superior to uPVC due to its durability, sleek design, and customisability. While uPVC is lighter and cheaper, aluminium offers a longer-lasting, more aesthetic solution that enhances the value and beauty of your home.

Is aluminium more expensive than uPVC?

Yes, aluminium is typically more expensive than uPVC. The higher cost is a result of aluminium's superior qualities, including its durability and strength. This investment pays off with the long-term benefits of enhanced longevity and minimal maintenance.

What is the lifespan of an aluminium roof lantern?

You can expect your aluminium roof lanterns to last over 25 years, provided it is looked after. Aluminium significantly outperforms other materials thanks to its resistance to corrosion, weathering and warping. This contributes to its longevity, making it a highly durable choice for any climate or environment.

What is the disadvantage of uPVC windows?

One significant disadvantage of uPVC windows is their susceptibility to warping and discolouration when exposed to high temperatures and direct sunlight. Additionally, uPVC frames have thicker sightlines that can reduce the amount of natural light entering a space and detract from the window's overall aesthetic appeal.
