The Lifespan Of uPVC Windows Vs Aluminium Windows

When the time comes for your commercial or residential property to undergo window and door repairs or replacement, several factors are likely to influence your decision: durability, cost-effectiveness, and energy efficiency, among others. Two popular options are uPVC (unplasticised polyvinyl chloride) and aluminium, both of which offer different advantages and disadvantages.

In this article, we’ll explore uPVC windows vs aluminium windows, focusing on their lifespan and the factors that can affect their durability.

uPVC Windows: The Low Maintenance, Energy-Efficient Option

uPVC windows are known for their energy efficiency, low maintenance, and cost efficiency. On average, uPVC windows have a lifespan of around 20 to 30 years, however, it’s essential to note that their lifespan depends on several factors, such as the quality of the uPVC material, the accuracy of the installation, and the frequency of maintenance.

Over time, uPVC windows may experience some issues. Due to prolonged exposure to sunlight, they may fade and discolour (this will be more noticeable with coloured variants than white uPVC), while temperature fluctuations can cause them to lose their shape. Regular cleaning and maintenance can help to minimise these effects and prolong their lifespan. It is recommended to clean uPVC windows with a mild detergent and avoid using abrasive cleaners that can damage the surface of the plastic.

Aluminium Windows: Sleek, Modern, And Durable

Aluminium windows are generally more durable than uPVC windows, with an extended lifespan of approximately 30 to 40 years. Aluminium is highly resistant to corrosion, so it is particularly suitable in properties that are exposed to harsh weather or salt water (for example, close to the coast). Additionally, aluminium windows offer a sleek, modern appearance that can enhance the aesthetics of a building.

While aluminium windows are very durable, they may not be as energy efficient as uPVC windows. uPVC window frames not only resist cold and dampness but also effectively retain the heat inside the building. In contrast, aluminium is a thermal conductor, so it will transfer heat or cold into a building more easily than uPVC. However, modern aluminium windows often feature thermal breaks or insulating materials to improve their energy efficiency.

Aluminium is almost always a more expensive option in the short term due to the more expensive materials and manufacturing processes used in their construction. Over the lifespan of the windows, however, these windows offer a healthy return on investment.

The Importance Of Professional Window Maintenance

It’s important to note that the lifespan of both uPVC and aluminium windows can be significantly extended with proper maintenance and upkeep.

Routine cleaning, lubrication of moving parts, and regular inspection for damage or wear-and-tear are essential. Replacing worn-out components, such as handles, hinges, and locks, can also contribute to an extended lifespan and reduces the need for complete uPVC or aluminium window replacement.
