Aluminium vs uPVC: Comparing Window and Door Materials

aluminium vs upvc windows

When it comes to choosing the right material for your windows and doors, two popular options that often come to mind are aluminium and uPVC. Both materials offer unique benefits and have their own set of advantages. In this article, we will compare aluminium and uPVC to help you make an informed decision for your next project.

Strength and Durability

Aluminium is known for its strength and durability. It is a robust material and is highly resistant to warping, cracking, and fading.

Aluminium frames are built to last, providing long-term performance and stability. On the other hand, uPVC is a lightweight material that offers good durability and requires minimal maintenance and with no corrosion. 

Energy Efficiency

When it comes to energy efficiency, both aluminium and uPVC have their own advantages. Aluminium profile sections are thermally broken, using a polyamide thermal barrier that enhances its thermal performance.

On the other hand, uPVC frames have excellent insulation properties and are known for their energy efficiency. The multi-chambered design of uPVC profiles and thermal composite insert offers superb insulation for year-round comfort and reducing energy consumption.

Design and Aesthetics

Aluminium frames are known for their sleek and modern appearance. They offer slim sightlines, allowing for larger glass areas and unobstructed views. Aluminium windows and doors can be customised to fit various architectural styles, and they come in a wide range of finishes and colours.

On the other hand, uPVC frames have a more traditional and versatile look. They are available in various styles, including casement, sliding sash, and tilt and turn, and can be easily customised to match your preferences.


Both aluminium and uPVC frames offer good security features.  They can be fitted with multi-point locking systems, toughened or laminated glass, and other security enhancements for PAS24 new builds. 


One of the key advantages of uPVC frames is their low maintenance requirements. uPVC is resistant to tarnishing, corrosion, and does not require painting or staining. Cleaning uPVC frames is as simple as wiping them with a damp cloth. Aluminium frames are also low maintenance, requiring occasional cleaning to keep them looking their best.

Installation and Cost

When considering aluminium and uPVC for your next project, it is important to take into account the installation process and cost implications. Aluminium frames are typically more expensive than uPVC frames due to the higher cost of materials and manufacturing. However, aluminium offers excellent longevity and durability, which can make it a worthwhile investment in the long run for your customers.

The installation of aluminium frames may require specialised expertise and equipment, which could add to the overall cost. On the other hand, uPVC frames are generally more affordable, and the installation process is relatively straightforward. uPVC windows and doors are widely available and can be easily installed by professionals, making them a cost-effective choice for many homeowners.

Environmental Considerations

When it comes to environmental impact, both aluminium and uPVC have their own considerations. Aluminium is a highly sustainable material and is recyclable without losing its properties.

Manufacturing uPVC innovative products helps us to contribute towards sustainable living and ensure energy savings, as a company we aim to keep our impact on the environment minimal by producing frames that have energy-efficient properties which can contribute to reducing carbon emissions in the long term.


Both aluminium and uPVC have their own set of advantages when it comes to windows and doors. Aluminium frames offer strength, durability, sleek design, and customisation options, while uPVC frames provide energy efficiency, versatility and low maintenance.

Ultimately, the choice between aluminium and uPVC will depend on your specific needs, preferences, and your customer’s budget. Consulting with a professional window and door supplier can help you make the best decision for your project.
