UPVC vs. Aluminium Windows: A Simple Comparison Guide

For those planning to make improvements in their home, ensuring you are choosing the proper fenestration and getting value for your money is crucial. Replacing old windows is one of the critical decisions, as they impact your house’s interior and exterior. Therefore, they need to leave a lasting impression. Talking about windows, both UPVC and aluminium are considered top choices – they are both durable, aesthetically appealing, and affordable window options for your home. The improved qualities of these materials make them a favoured option for residential as well as commercial use.

In this post, you will learn the wonders of uPVC and aluminium windows that will help you understand which will fit right with your home.


UPVC is a perfect blend of unplasticised polyvinyl chloride, a standard rigid plastic material. It is newly used for doors and windows and is immune to dampness, erosion, pollution, and mould. UPVC windows give a look for aluminium and have been the best choice. Many people have changed their taste from traditional to cutting-edge UPVC windows and doors. For those who want beautiful windows, uPVC windows look like aluminium, are of top and are affordable, and deliver great covering from smog and lousy weather.


Aluminium is a robust and lightweight material. For many years, aluminium has been used to fabricate fenestration for the best look. Considering its structural composition, aluminium is durable and sturdy. These windows made their mode onto everyone’s checklist. Thin aluminium units impact practicality and polish to take the weight.

Difference between Aluminium and uPVC windows 


UPVC windows are considered durable and highly resistant to corrosion, rot, and termites. They have the ability to withstand harsh weather conditions. They are low maintenance but can fade – fret not! Regular cleaning keeps them as good as new for a couple of years or two. Aluminium-crafted windows are lightweight, strong, and highly resistant to extreme weather. However, they can experience thermal expansion problems and demand periodic maintenance. Both windows have a long lifespan when properly maintained.

Common Applications

Both window types are commonly used across different applications, each offering unique advantages to the table. UPVC windows are used for residential properties since they bring excellent thermal insulation, low maintenance requirements and soundproofing. They are considered the best option for homes in moderate climates – however, aluminium windows are commonly used in commercial buildings. Their sleek look, robustness and resistance to harsh weather make them a popular choice for contemporary structures.

Better Options

It’s natural to feel confused when it comes to having choices; both uPVC and aluminium windows bring you options to suit different preferences. UPVC window frames are available in different finishes and colours, enabling customisation and seamless integration with your home’s design. Aluminium window frames offer versatility with their sleek profiles and large glass pane, allowing expansive views and ample natural light.


UPVC fenestration and Aluminium Fenestration have unique characteristics when considering the environmental impact. They leave a low carbon footprint and are energy-efficient when it comes to insulation, thereby reducing heating and cooling requirements. Since they are recyclable, they make a green choice. Aluminium windows are also recyclable; they tend to consume more energy during production and have a higher carbon footprint. They are similarly durable and can last up to decades, potentially offsetting its initial environmental impact.


When it comes to strength, aluminium windows have the benefit. Aluminium fenestration is made of a robust material known for its structural integrity and can withstand extreme external forces. It is resistant to impacts and offers improved security. UPVC windows, while they are durable, they are not as strong as aluminium. UPVC windows offer just enough strength for residential applications; however, aluminium makes a perfect choice for commercial settings.


UPVC windows outperform aluminium when it comes to insulation. UPVC has remarkable thermal insulation properties, which create a barrier that helps to prevent heat transfer and maintain a comfy indoor environment. This insulation capability helps reduce energy consumption for heating and cooling purposes, which results in potential energy savings. Aluminium is a conductor of heat and cold – which makes aluminium-framed windows less effective at insulation. Additional measures like thermal breaks or double-glazing can be added to an aluminium window frame to improve the overall insulation.


UPVC windows have the advantage of being low maintenance; their frames don’t demand painting or sealing and are highly resistant to corrosion and termite damage. You can clean them with a microfiber cloth dipped in soap water. At the same time, aluminium-framed windows and doors require more maintenance. Although they are naturally resistant to corrosion, annual lubrication of moving parts may be needed to prevent issues.


When it comes to security, both window types offer remarkable protection. However, aluminium windows are considered to be more secure. They are constructed using robust material (as mentioned earlier) that offers excellent resistance against forced entry or theft. Aluminium windows can be fitted with a multi-locking mechanism and reinforced glass for improved security. While UPVC is also secure, aluminium frames are preferred for commercial buildings where added security is a primary concern.


This is another aspect to consider when comparing different window frames: uPVC windows provide better insulation against noise compared to aluminium models. The inherent properties of UPVC help create a tight seal, such as density and their ability, which makes them effective at reducing external noise infiltration.


While there are many misconceptions about aluminium windows, both uPVC windows and aluminium windows are fairly similar. The choice comes down to personal preference, what suits your home’s interior and your budget. For those on a tighter budget, uPVC fenestration solutions make a perfect choice. But for those on a flexible budget and who have a contemporary theme home, aluminium homes might be your preference.
