Aluminium vs. uPVC Conservatories: Pros & Cons

When it comes to choosing the perfect conservatory for your home, aluminium vs. uPVC is a long-standing debate. Both options offer unique advantages and drawbacks that can greatly impact the functionality and aesthetics of your space. In this article, we explore the world of conservatories and discuss the pros and cons of aluminium and uPVC constructions. Our guide aims to help you make an informed decision that aligns with your preferences and budget.


Pros of aluminium


  • Has a sleek design

  • Its modern aesthetic appeals to those looking for a contemporary addition to their homes that exudes elegance and sophistication.

  • Is durable. Unlike other materials, such as uPVC, aluminium is known for its strength and longevity, making it a reliable choice for conservatories.

  • The low maintenance requirements of aluminium make it an attractive option for busy homeowners. With minimal upkeep needed to keep its finish looking pristine, aluminium offers convenience without compromising on style or quality. This aspect can save both time and money in the long run.


Cons of aluminium

While aluminium is a popular choice for conservatory frames, it does have its drawbacks:

  • Aluminium frames can be prone to condensation issues, which may eventually lead to mould or mildew growth if not properly managed.

  • Another disadvantage of aluminium is its susceptibility to corrosion over time, particularly in coastal areas where salt and moisture levels are higher. This can compromise the structural integrity of the conservatory frame and necessitate costly repairs or replacements.


Pros of uPVC


When it comes to choosing between aluminium and uPVC for your conservatory, the advantages of uPVC are hard to ignore.

  • Cost-effective compared to aluminium

  • Boasts impressive energy efficiency properties. The insulating properties of uPVC help maintain a comfortable temperature inside your conservatory throughout the year, potentially saving you money on heating and cooling bills.

  • Ease of installation. With lightweight frames and the ability to be easily shaped and customised, uPVC conservatories can be quickly and efficiently installed without compromising quality. This not only saves you time but can also reduce labour costs associated with installation.

Cons of uPVC

While uPVC conservatories have their advantages, there are also several notable cons to consider.

  • Limited design options available compared to aluminium. This can restrict homeowners who want more customised or unique finishes for their conservatory.

  • Susceptibility to discolouration over time, especially when exposed to harsh sunlight or extreme weather conditions. This can lead to a less aesthetically appealing look and potentially reduce the overall value of the property.

  • May not be as strong or durable as aluminium, making it more prone to damage from impacts or wear and tear over the years.


When it comes to aesthetics, both aluminium and uPVC conservatories offer a range of appearance and customisation options to suit different preferences. Aluminium conservatories are known for their sleek, modern look, which can add a touch of sophistication to any home. With a variety of colour choices and finishes available, homeowners have the freedom to personalise their conservatory to match their existing decor or create a standout feature.

On the other hand, uPVC conservatories provide a more traditional aesthetic with classic white frames that offer a clean and timeless appeal. However, this doesn’t mean that customisation is limited. Homeowners can still choose from different colours and woodgrain effects to achieve a more bespoke look. Additionally, the versatility of uPVC material allows for unique shapes and designs to be easily achieved, offering endless possibilities for creating a custom conservatory that stands out from the rest.


Aluminium conservatories are known for their exceptional longevity, able to withstand the test of time without warping or deteriorating. The material’s resistance to rust and corrosion makes it an ideal choice for areas with harsh weather conditions. On the other hand, uPVC conservatories are also highly durable and resistant to weather elements such as rain, wind, and sunlight. They require minimal maintenance to keep them looking new for years to come.


Aluminium conservatories tend to be more durable and require minimal upkeep. Cleaning aluminium simply involves a wipe down with soapy water, removing the need for frequent repainting or repairs.

Meanwhile, regular upkeep of uPVC conservatories involves simple cleaning routines that can keep your space looking fresh and inviting. For tougher stains or stubborn debris, consider using specialised uPVC cleaning products that are designed to effectively clean and protect your conservatory materials without causing damage.


So which is cheaper: uPVC or aluminium?

Well, when comparing the cost of uPVC and aluminium for conservatories, the picture isn’t entirely straightforward. While uPVC tends to be the more budget-friendly option upfront, especially when considering basic designs and sizes, it’s essential to factor in long-term costs. Aluminium may have a higher initial price tag due to its premium quality and durability, but it often requires little to no maintenance over its lifespan.

uPVC generally offers a more cost-effective option due to its larger and thicker frames compared to aluminium. This difference in frame size directly impacts the overall cost, making uPVC an attractive choice for those looking to stay within budget.
