Most buyers choose uPVC windows for their house, considering their cheap cost and market availability. This one decision can cost you frequent runs for maintenance and a new window requirement within 10 years.

Both Aluminium windows and uPVC windows are assumed to be contemporary and durable window solutions for a home. The enhanced components of these materials make them a suitable prospect for residential use. But there are arguments and questions on which window design option is best for your home and why?

Here is a comparative analysis to understand the essential aspects of both windows.


uPVC is a synthetic plastic polymer, with an average life span of about 25 to 30 years. 

While; Aluminium window frames are known to last for more than 50 years. Aluminium windows come under the phrase ‘fit and forget’.

What sets aluminium windows apart from other metals is its rust-resistant feature. Aluminium window frames do not degrade in the same way that uPVC windows and doors do. 

Design Flexibility:

Aluminium windows are available in various styles – casement, slidinglouvres and integrated blinds windows. They can be fabricated as single-, double- or triple-glazed units.

The aluminium windows sections are finished with a durable powder coating or anodising. The powder coating imparts a stunning look and does not discolour, corrode or peel easily. 

So many design and fabrication variations are not available in UPVC windows. Also, some homeowners don’t find uPVC attractive because of its plastic look.


Aluminium windows are robust, lightweight material. Thin aluminium windows sections also impart elegance and can be used effectively to handle the weight of glass. The sleek sections (Check Sl-26 for sleek aluminium frame) thereby increase the surface area of glass and allow sunshine to filter into the interiors. 

Aluminium windows sections are thinner than uPVC and have a higher ratio of glass.


Aluminium windows and doors are 100 per cent recyclable and, the recycled material has the same high quality as virgin aluminium. It can be melted and reformed indefinitely making it one of the most environmentally friendly materials in use. 

While uPVC is fabricated from a synthetic plastic polymer which is harmful and unsustainable for the environment.

But there’s no getting away from it, uPVC windows are the cheaper of the two options. But is it cost-effective? 

If you plan to stay in your property for a long time, aluminium windows will last for many more years, so you won’t have to go through the upheaval of replacing the windows so often. 

Why choose aluminium windows?
