When choosing new windows for your home, the debate between aluminium and uPVC windows (unplasticised polyvinyl chloride) is common. Both materials offer unique benefits, and the question “Which is better: aluminium or uPVC windows?” is frequently asked by homeowners looking to upgrade their property. At BSF Windows, we understand the importance of making an informed decision, so we’ve compiled this comprehensive guide to help you compare these two window types.
In this article, we’ll delve deep into the characteristics of aluminium and uPVC windows, comparing them across various factors such as durability, energy efficiency, aesthetics, and cost-effectiveness.
By the end, you’ll clearly understand which option might be the best fit for your specific needs and preferences.
Durability and Longevity
Aluminium Windows: Built to Last
Aluminium windows are renowned for their exce
ptional durability. As a highly durable material, aluminium can withstand extreme weather conditions and resist corrosion. Aluminium’s inherent strength also ensures that these windows maintain structural integrity over time. Along with its strength, aluminium also has slimmer frames, which can maximise natural light and create a sleek appearance.
uPVC Windows: Reliable and Low Maintenance
uPVC frames excel in their resistance to rot, rust, and fading. This makes them highly durable in various weather conditions. In addition, uPVC windows are easy to clean and do not require regular painting or treatment.
Energy Efficiency
Aluminium Windows: Modern Thermal Performance
Traditionally, aluminium windows were known for their poor thermal performance due to the material’s high conductivity. At BSF Windows, our aluminium windows incorporate thermal break technology, significantly improving their energy efficiency. This innovation helps reduce heat transfer, making the windows more efficient and saving you on your heating costs.
uPVC Windows: Natural Insulators
uPVC is naturally an excellent insulator, making it highly energy efficient. These windows help keep homes warm in winter and cool in summer, potentially leading to lower energy bills. When combined with double or triple glazing, uPVC windows offer outstanding thermal performance.
Aesthetics and Design
Aluminium Windows: Sleek and Modern
Aluminium windows are often chosen for their sleek, contemporary appearance. The strength of aluminium allows for much slimmer frames, creating a more modern look and maximising glass area for better views and increased natural light. Aluminium windows are available in many colours and glazing finishes, offering great design flexibility.
uPVC Windows: Classic and Versatile
uPVC windows come in various styles and can be designed to suit both modern and traditional homes. While they typically have thicker frames than aluminium, advancements in uPVC technology have allowed for slimmer profiles in recent years. Our uPVC windows are available in various colours, including wood-grain effects.
Cost Considerations
Aluminium Windows: Premium Investment
Aluminium windows generally cost more than uPVC. However, their durability and long lifespan can make them a cost-effective choice in the long term, especially for those planning to stay in their homes for many years.
uPVC Windows: Budget-Friendly Option
uPVC windows are typically more affordable than aluminium, making an attractive choice for homeowners looking for a quality option that fits within their budget. Their energy efficiency can also contribute to cost savings on energy bills over time.
Maintenance Requirements
Aluminium Windows: Minimal Upkeep
Aluminium windows require very little maintenance. They don’t rot, warp, or rust and typically only need occasional cleaning to keep them looking their best. The powder-coated finish on most aluminium windows is highly resistant to fading and peeling.
uPVC Windows: Easy to Maintain
uPVC windows are also known for their low maintenance requirements. They don’t need painting or sealing and can be easily cleaned with soap and water. uPVC is resistant to fading and discolouration, maintaining its appearance over time.
Environmental Considerations
Aluminium Windows: Recyclable and Sustainable
Aluminium is 100% recyclable and can be recycled indefinitely without losing its properties. This makes aluminium windows an environmentally friendly choice for those concerned about sustainability.
uPVC Windows: Improving Sustainability
While historically less eco-friendly, the uPVC industry has made significant strides in improving the material’s sustainability. Many uPVC windows are now made from recycled materials and can be recycled at the end of their life.
Security
Aluminium Windows: Strong and Secure
The inherent strength of aluminium makes these windows naturally secure. At BSF Windows, our aluminium windows are built with extra security features, including multi-point locking systems and toughened glass.
uPVC Windows: Advanced Security Options
Modern uPVC windows have advanced locking mechanisms and can be reinforced for additional security. The frames are strong and resistant to forced entry.
Which is better, aluminium or uPVC windows?
So, which is better: aluminium or uPVC windows? It all depends on your personal preference.
Aluminium excels in:
- Durability – Aluminium frames are naturally more robust and easier to maintain. They are less likely to warp or rust.
- Maintenance – Aluminium is much thinner than uPVC, making it easier to maintain and clean.
- Environmental friendliness – Aluminium is a more eco-friendly material that is fully recyclable.
uPVC excels in:
- Energy efficiency – uPVC excels at regulating your home’s temperature and being energy efficient.
- Cost-effectiveness – uPVC’s upfront cost is cheaper, and the slightly better thermal efficiency can reduce energy bills.
Both window types offer unique benefits and can be excellent choices depending on your needs, preferences, and budget.
Aluminium windows stand out for their strength, slim profiles, and modern aesthetic. They’re an excellent choice for contemporary homes, however, they come with a higher upfront cost.
uPVC windows offer excellent energy efficiency, affordability, and versatility in design. While they are not as slim or strong as aluminium, they provide excellent value for money and performance.
Ultimately, the best choice for your home will depend on factors such as:
-
- Your budget
- The style of your home
- Your energy efficiency priorities
- The specific types of windows you need
- Your local climate
- Your long-term plans for the property
