UPVC Roof Lanterns Explained
UPVC, or Unplasticized Polyvinyl Chloride, is a lightweight, affordable material often used in windows, doors, and roof lanterns.
Its affordability and practicality have made it a popular choice for many homeowners.
However, beyond its budget-friendly appeal, UPVC has several characteristics worth exploring.
Benefits of UPVC Roof Lanterns
uPVC roof lanterns come with a range of benefits:
Affordable and Practical:
UPVC is one of the most cost-effective materials for roof lanterns. It’s ideal if you’re looking for a solution that doesn’t compromise your budget while still delivering plenty of natural light.
Low Maintenance:
One of the standout benefits of UPVC is how easy it is to care for. It resists rotting and rust, so there’s no need for frequent upkeep or repainting. A simple wipe-down keeps it looking fresh.
Great Thermal Insulation:
UPVC is a great insulator that helps regulate indoor temperatures. In winter, it keeps the heat in; in summer, it keeps the heat out—potentially helping to lower your energy bills.
Versatile Designs:
While UPVC is often associated with traditional styles, there are plenty of modern designs available that can suit a variety of home aesthetics.
Downsides of UPVC Roof Lanterns
Here are a few potential downsides associated with uPVC roof lanterns:
Durability Over Time:
While UPVC is durable, it’s not invincible. Over time, exposure to UV rays and weather conditions can cause discolouration, fading, or even brittleness.
Chunkier Frames:
UPVC frames tend to be thicker than aluminium ones, which might reduce the overall glass surface area and the amount of light entering your home.
Size Limitations:
UPVC works well for small to medium-sized roof lanterns, but for larger spans, it lacks the structural strength and support of aluminium.
Aluminium Roof Lanterns Explained
Aluminium is a premium material prized for its strength, modern aesthetics, and durability. It’s an excellent choice for homeowners who want a sleek, stylish look combined with robust performance.
Advantages of Aluminium Roof Lanterns
Aluminium roof lanterns come with the following advantages:
Superior Strength:
Aluminium can support larger roof lanterns thanks to its high strength-to-weight ratio. This makes it ideal for creating expansive designs that flood your home with light.
Example: If you’re installing a lantern over a large kitchen or living area, aluminium’s strength ensures the structure remains stable and secure.
Slimline Frames for Maximum Glass:
One of aluminium’s standout features is its slimline frames, which allow for more glass and, consequently, more natural light.
It’s perfect for homeowners who want to blur the lines between indoor and outdoor spaces.
Modern Aesthetic Appeal:
Aluminium offers a sleek, contemporary look that adds a high-end finish to any home. It’s particularly popular in modern extensions and open-plan designs.
Sustainability:
Concerned about the environment? Aluminium is a recyclable material, making it an eco-friendly choice for sustainable home improvements.
Disadvantages of Aluminium Roof Lanterns
While there can be a few disadvantages for aluminium roof lanterns, such as a higher initial cost, these are easily outweighed by the long term value and performance that they offer for your home.
Higher Initial Cost:
Aluminium roof lanterns are a premium option, so they can come with a higher upfront cost.
However, due to their durability and long lifespan, this makes them a worthwhile investment for anyone looking to add the wow factor to their home!
Insulation Performance:
This used to be a concern with older aluminium roof lanterns, whoever thanks to modern technologies this has been much improved.
Thanks to the thermal breaks in the aluminium roof lantern frames and the availability of triple glazing, they are able to improve energy efficiency and offer good performance when they are compared with their uPVC counterparts

Choosing Between Aluminium vs UPVC Roof Lantern: What To Consider
Making the right decision between aluminium and UPVC roof lanterns means considering what matters most to you—durability, cost, or design.
Let’s take a closer look at the key factors:
Durability
If you’re looking for a material that can stand up to the elements and provide lasting performance, aluminium is the way to go.
Its resistance to warping, cracking, and discolouration means it’ll look and perform great for decades.
You can even get a marine-grade finish if you live in coastal areas for added protection and increased durability!
While it is durable and less expensive up front, uPVC may show signs of ageing after years of exposure to sunlight and harsh weather, leading to needing to be replaced and additional costs further down the line.
Cost
On a tight budget? UPVC is often the more affordable option upfront, making it a practical choice for smaller projects or budget-conscious homeowners.
However, aluminium’s longevity and minimal maintenance needs can provide better long-term value and a worthwhile investment.
Amount of Natural Light
Here’s where aluminium truly shines—literally!
Thanks to its slimline frames, aluminium roof lanterns maximise the amount of glass, allowing more sunlight to stream into your home. If natural light is a priority, aluminium is your best bet.
Aesthetics
Aluminium roof lanterns deliver a sleek, modern look that suits contemporary homes and extensions beautifully.
On the other hand, UPVC is a solid choice for traditional styles but lacks the premium finish and versatility of aluminium.
