Aluminium Vs uPVC Windows

Choosing between aluminium vs uPVC can be a tough decision – especially when both of them deliver top-notch performance, energy-efficiency, durability and cost-saving benefits. Additionally, they provide a range of colour and texture options to suit your style and preferences. 

In this article, we’ll help you understand the subtle differences between aluminium and uPVC windows and which one you should be choosing for your next window installation project. 

What are Aluminium windows made of and what are its benefits?

Aluminium windows are naturally made of aluminium, a lightweight and durable metal. The manufacturing process typically involves extruding aluminium profiles to create the frame components, which are then cut and assembled into window frames.

Here are some of its benefits:

Enhanced durability:

Aluminium is inherently strong and resistant to corrosion, making it well-suited for window frames. Hence aluminium windows can withstand harsh weather conditions without warping, fading, cracking or rotting, ensuring exceptional strength and longevity.

Slim Profiles:

Aluminium frames can be designed with slim profiles, allowing for large expanses of glass and bringing in natural light intake. This therefore makes your home well-ventilated and bright across all seasons. 

Customisation Options:

With our Aluminium windows, you can choose from a range of colour and finish options to match and complement your home’s exterior or interior design scheme. 

Low Maintenance:

Aluminium windows require minimal upkeep compared to other materials like wood. They do not need to be painted or sealed regularly, and cleaning is typically straightforward, requiring only soap and water. 

Energy Efficiency:

Modern aluminium window designs often incorporate thermal breaks—insulating materials placed between the interior and exterior of the frame—to improve energy efficiency. When paired with double glazing, these windows can provide excellent insulation, reducing heating costs and maintaining an optimal temperature.


What are uPVC windows made of and what are its benefits?

Unplasticized polyvinyl chloride also known as uPVC windows are made primarily or a type of plastic known as PVC, which is combined with certain additives to enhance its properties.

Here are the key features and benefits of uPVC windows:

Multi-chambered Profiles:

uPVC window frames are typically constructed with multi-chambered profiles, which provide enhanced insulation and thermal efficiency. These chambers trap air, reducing heat transfer and improving energy efficiency in the home. 

Sound Insulation:

uPVC windows offer good sound insulation properties, helping to minimise outside noise pollution and creating a quieter and more peaceful indoor environment. 

Security Features:

Our high quality uPVC window frames can be reinforced with steel or aluminium for added strength and safety. Additionally, modern uPVC windows are designed to accommodate advanced locking systems providing increased protection against intruders. 


uPVC windows are generally more affordable than alternatives such as aluminium or timber frames, making them an affordable choice for homeowners looking to upgrade their home without breaking the bank.

Which is Better?

When it comes to choosing between aluminium and uPVC windows, we would suggest that both are an excellent choice. It truly depends on your budget, preference and personal home requirements. Some people may think that the appeal of aluminium is better but uPVC or aluminium both are designed using top materials for new or replacement windows.
