UPVC vs Aluminium: Which One is Right for Your Home?


When it comes to choosing the right material for your home’s windows and doors, two popular options often come to mind: UPVC and Aluminium. Both have their unique advantages and disadvantages, making the decision a bit challenging. In this article, we will delve deep into the characteristics of both UPVC and Aluminium to help you make an informed choice.

What is UPVC?

Definition and Composition

Unplasticized Polyvinyl Chloride, is a type of plastic known for its rigidity and durability. Unlike regular PVC, it is not softened by the addition of plasticizers, making it ideal for construction purposes.

Common Uses in Home Construction

UPVC is commonly used for window frames, doors, and piping in home construction. Its popularity stems from its resistance to weathering, low maintenance needs, and excellent insulating properties.

What is Aluminium?

Definition and Composition

Aluminium is a lightweight, corrosion-resistant metal widely used in various industries, including construction. Its strength and flexibility make it a preferred choice for many architectural applications.

Common Uses in Home Construction

In homes, Aluminium is often used for window frames, door frames, and curtain walls. Its sleek, modern look and durability are major selling points for homeowners and builders alike.

Durability and Longevity

UPVC Durability

UPVC is known for its long-lasting nature. It is resistant to rot, rust, and corrosion, which makes it an excellent choice for areas with harsh weather conditions. UPVC windows and doors can last for decades with minimal maintenance.

Aluminium Durability

Aluminium is also highly durable and resistant to the elements. However, it can corrode over time if not properly treated or maintained. Modern Aluminium products often come with protective coatings to enhance their longevity.


Both materials are durable, but UPVC has a slight edge due to its resistance to corrosion without the need for additional treatments. Aluminium’s durability largely depends on the quality of its protective coatings.

Energy Efficiency

Insulating Properties of UPVC

UPVC has excellent insulating properties, helping to keep homes warm in the winter and cool in the summer. This can lead to significant energy savings over time.

Insulating Properties of Aluminium

Aluminium, by itself, is a poor insulator. However, modern Aluminium frames often come with thermal breaks—materials that reduce the transfer of heat, improving their energy efficiency.

Which One is More Energy Efficient?

UPVC is generally more energy-efficient due to its natural insulating properties. Aluminium can be made energy-efficient with the addition of thermal breaks, but it usually does not match the insulating performance of UPVC.

Maintenance Requirements

Maintenance of UPVC

One of the biggest advantages of UPVC is its low maintenance requirements. It does not need painting or sealing and can be easily cleaned with soap and water.

Maintenance of Aluminium

Aluminium requires a bit more upkeep. While it does not rust, it can oxidize over time. Regular cleaning and occasional treatment to prevent corrosion are necessary to maintain its appearance and functionality.


UPVC wins in terms of low maintenance. Aluminium requires more effort to keep it looking and performing its best over the years.

Aesthetic Appeal

Aesthetics of UPVC

UPVC windows and doors come in a variety of colors and finishes, including wood grain effects. However, they tend to have a bulkier look compared to Aluminium.

Aesthetics of Aluminium

Aluminium offers a sleek, modern aesthetic with thinner frames and a variety of finishes, including anodized and powder-coated options. It provides a more contemporary look that appeals to many homeowners.

Which One Looks Better?

The choice between UPVC and Aluminium largely depends on personal preference. UPVC offers versatility in style, while Aluminium provides a modern, streamlined appearance.

Environmental Impact

Environmental Impact of UPVC

UPVC is made from plastic, which raises concerns about its environmental impact. However, it is highly durable and recyclable, which helps mitigate some of these concerns.

Environmental Impact of Aluminium

Aluminium is also recyclable and has a long lifespan. Its production, however, is energy-intensive, which can impact its environmental footprint.

Which One is More Eco-friendly?

Both materials have environmental pros and cons. UPVC is less energy-intensive to produce but raises plastic pollution concerns, while Aluminium is recyclable but energy-intensive to manufacture. The choice depends on which environmental factors are more important to you.

Security Features

Security of UPVC

windows and doors often come with multi-point locking systems, enhancing their security. The material itself is robust, providing a good level of protection.

Security of Aluminium

Aluminium is strong and can support advanced locking mechanisms, making it very secure. Its strength makes it resistant to forced entry.

Which One is More Secure?

Both of them offer high security levels. The choice depends on the specific locking systems and the overall design of the windows and doors.


Choosing between them for your windows and doors depends on your specific needs and preferences. UPVC is cost-effective, low-maintenance, and energy-efficient, making it ideal for budget-conscious homeowners. Aluminium, on the other hand, offers superior aesthetics, customization options, and potential resale value, but at a higher upfront cost. Consider what factors are most important to you—whether it’s budget, design flexibility, maintenance, or environmental impact—before making your decision.
