A Review on the Difference Between Aluminium and PVC Windows

27 May 2021

Windows have been integral to properties when it comes to overall style and appearance. With carefully positioned windows, they can provide great outdoor views and excellent natural lighting. They can likewise regulate temperature and ventilation better, which can be great for saving energy.

One factor that you must always consider when choosing your windows is their material. The materials available for windows may offer different styles and colours. They can also boast varying levels of strength, durability, thermal efficiency, and price.

There are two materials that a lot of property owners often choose. These are aluminium and polyvinyl chloride or PVC. The following are some of the notable differences between the two.


Aluminium windows are known for their sleek style, which can be attributed to their slim and thin profile. Aside from their sleeky style, aluminium windows are also known for improving sightlines. The absence of huge obstructions on the view of the windows allows them to offer great outdoor views for the people inside the property. This specific style of these windows makes them very famous in modern properties.

PVC windows, on the other hand, tend to be bulky, which is a quality that somehow turns some property owners off. However, one quality that makes PVC windows preferred by others is their versatility in terms of colours and finishes. Property owners can opt for PVC windows if they want to achieve certain effects.


Both aluminium and PVC windows can resist most of the surrounding elements. However, the average lifespan of these window materials can still differ as they have varying primary composition.

Aluminium windows can easily resist corrosion, which cannot be said with other types of metal materials. And given their strong and durable qualities, they can easily last for up to 45 years. PVC windows, alternatively, can only last for around 20 to 30 years. Their lifespan may be shorter than the aluminium ones, but it is still lengthy considering that PVC windows can also withstand damaging elements.

Thermal Efficiency

Another factor that is different between aluminium and PVC windows is thermal efficiency. Before, aluminium windows are not truly utilised by property owners as they would only allow heat to pass through the property spaces. Today, however, these windows can already boast high thermal efficiency thanks to the incorporation of thermal breaks. PVC windows are also thermal-efficient. As long as they are processed correctly, both aluminium and PVC windows can effectively regulate the entry of heat.


One more factor that is different between aluminium and PVC windows is their overall price. The price of buying aluminium windows is known to be much more expensive than PVC windows given that the former has high material and manufacturing costs. However, the longevity of aluminium windows makes them more ideal for property owners who want to save a lot of money in the long run.

PVC windows are cheaper than aluminium windows. They can also be cost-effective since they do not get damaged easily. And with their lower costs, property owners can allocate some of their money to other necessary upgrades or enhancements for their properties.
