Aluminium vs UPVC Windows: Key Differences You Need to Know

When choosing between UPVC or aluminium windows for your home, it's important to consider material composition, thermal efficiency and design flexibility. Each window type offers unique benefits that cater to different homeowner priorities.

Cost Differences between UPVC and Aluminium Windows

When comparing aluminium windows to UPVC, you'll typically find that aluminium windows are more expensive. This is because aluminium is a more costly material to source, and the production process is generally pricier as well. For more pricing details for both options, check out our aluminium window cost guide and UPVC window cost guide.

UPVC and Aluminium Windows: Material Composition and Durability

UPVC, or Unplasticised Polyvinyl Chloride, is a sturdy plastic often used in window frames due to its resistance to rust and rot. It requires minimal maintenance and can last for several decades.

Aluminium windows, made from lightweight metal, are known for their robustness and sleek finishes. They resist corrosion and offer lasting durability despite being more prone to dents than UPVC.

UPVC vs Aluminium Windows: Thermal Efficiency and Insulation Compared

Both UPVC and aluminium windows offer appreciable thermal efficiency but in varying degrees.

UPVC windows provide strong energy efficiency due to their excellent insulation properties, helping to reduce heating costs in colder months.

Aluminium windows can also be energy-efficient when fitted with a thermal break, although they may be slightly less insulating than UPVC.

Aesthetic and Design Flexibility of UPVC and Aluminium Windows

Both UPVC and aluminium windows offer versatile design options, making them popular choices among homeowners.

UPVC windows are characterised by clean, smooth lines and suit a variety of home styles, from traditional to contemporary. They come in an array of colours and finishes, including woodgrain effects that mimic timber windows.

Many homeowners are rightly concerned about security, which is why UPVC windows come equipped with a multi-point locking system as standard. Some models also include a shootbolt lock – an additional security mechanism at the top and bottom of the window – providing extra protection.

UPVC windows typically have a lifespan of 20-30 years. Their longevity depends on the quality of installation and maintenance.

Aluminium windows, by contrast, offer a sleek, modern aesthetic with slimmer frames that allow for larger glass panes, increasing natural light. The material's inherent strength supports more extensive design configurations, such as bi-fold or sliding windows, enhancing flexibility in custom designs.

They typically last 45 years or more, making them a long-term option. Aluminium is rust-resistant, weatherproof and won’t swell or crack in heat.

Noise Reduction: UPVC vs Aluminium Windows

The ability to block external noise is essential for homes in busy areas. Both UPVC and aluminium windows offer sound insulation, but their effectiveness depends on the environment.

UPVC windows perform well in noise reduction due to their multi-chambered frame design, which absorbs sound vibrations. They suit urban homes, busy streets and properties near airports where noise control is important.

Aluminium windows perform well when paired with quality double or triple glazing.

Their sleek frames allow larger glass panes, making them suitable for modern homes, high-rise apartments or industrial areas requiring sound insulation.

By matching the material to your home's location and needs, you can enjoy a quieter, more comfortable living space.

Sustainability: How UPVC and Aluminium Compare

Eco-conscious homeowners prioritise sustainability when selecting windows, weighing the environmental pros and cons of UPVC and aluminium. Each material offers unique benefits, helping individuals align their choices with their values.

UPVC Manufacturing: UPVC windows rely on petrochemicals, raising environmental concerns. However, they consume less energy during production compared to aluminium.

Aluminium Sustainability: Aluminium windows require an energy-intensive process to extract and refine bauxite ore. Despite this, aluminium’s durability and recyclability—without quality loss—make it a long-term, eco-friendly option.

Recycling and Sustainability: UPVC vs Aluminium Windows

Recycling and disposal are key factors in determining the environmental sustainability of UPVC and aluminium windows. Each material presents distinct advantages and challenges in the recycling process.

Recycling UPVC: UPVC can be recycled, but the process is more complex due to chemical additives. While proper recycling can significantly reduce landfill waste, the challenges of additive removal and limited secondary markets affect its overall sustainability.

Recycling Aluminium: Aluminium offers a straightforward recycling process, maintaining its quality and reducing reliance on virgin material extraction. Recycling aluminium saves up to 95% of the energy needed for new production, making it an environmentally preferable choice. Despite requiring initial separation and cleaning before processing, its long-term benefits outweigh this.

Are aluminium windows stronger than UPVC?

Yes, aluminium is a stronger material than UPVC, making it suitable for larger windows and complex designs like bi-fold or sliding doors. This strength allows for slimmer frames and maximised glass areas.

Can UPVC windows fade over time?

Older UPVC windows were prone to fading, but modern designs include UV-resistant coatings that reduce the risk of discolouration, even with prolonged sun exposure.

Do aluminium windows rust?

No, aluminium windows do not rust. Aluminium is naturally corrosion-resistant, making it an appropriate choice for homes in areas with high humidity or near the coast.

Can you retrofit aluminium windows into existing frames?

Yes, aluminium windows can often be retrofitted into existing window openings. However, professional installation is recommended to ensure a secure and energy-efficient fit.

Which windows are easier to clean: aluminium or UPVC?

Both are easy to clean with minimal maintenance. UPVC may require occasional cleaning to prevent dirt buildup, while aluminium frames are less prone to staining and better retain their finish.
