Windows are an integral part of any building for aesthetic and functional purposes. Choosing the right material for your windows is a crucial decision that will impact your building’s look, comfort, and energy efficiency. Two popular choices for window frames are UPVC and aluminium. Each material has its own advantages and disadvantages, and in this article, we will explore them to help you make an informed decision.
UPVC Windows
Advantages of UPVC Windows
UPVC windows are made of unplasticised polyvinyl chloride, a type of plastic that is durable, low-maintenance and affordable. Here are some advantages of UPVC windows:
- Cost-effective: UPVC windows are economical, making them a great choice for large installations. They are cheaper than aluminium windows and require less maintenance than wood windows, making them a great value for money.
- Energy-efficient: UPVC windows are great insulators, providing excellent thermal efficiency. They keep your home warm in the winter and cool in the summer, helping you save money on energy bills.
- Low-maintenance: UPVC windows are easy to clean and maintain. They don’t require painting or sealing and won’t warp, rot or fade. They only need a wipe with a damp cloth to look as good as new.
- Noise reduction: UPVC windows have excellent noise reduction properties. Their non-conductive qualities make them great for absorbing sound waves, providing you with a quieter and more peaceful home.
- Durability: UPVC windows are incredibly durable and long-lasting. They are resistant to weather, corrosion, and rot, making them ideal for harsh climates and coastal areas.
Disadvantages of UPVC Windows
- Limited colour options: While UPVC windows are available in a variety of colours, they are limited to solid colours and cannot be painted over.
- Aesthetics: UPVC windows have a plastic appearance that some people find unattractive. This is a matter of personal preference and may not be an issue for everyone.
Aluminium Windows
Advantages of Aluminium Windows
Aluminium windows are made of a strong, lightweight metal that is highly durable and resistant to weather and corrosion. Here are some advantages of aluminium windows:
- Aesthetics: Aluminium windows have a sleek, modern appearance that many people find attractive. They are available in a wide range of colours and finishes, including custom powder-coated finishes.
- Durability: Aluminium windows are incredibly strong and long-lasting. They are resistant to weather, corrosion, and rot, making them ideal for harsh climates and coastal areas.
- Slim frames: Aluminium frames are typically much thinner than UPVC frames, making them ideal for picture windows where the view is important.
- Recyclable: Aluminium is a highly recyclable material that can be recycled with minimal processing, making it an environmentally friendly option.
Disadvantages of Aluminium Windows
- Cost: Aluminium windows are more expensive than UPVC windows. They have a higher price tag but are still less expensive than wooden windows.
- Energy efficiency: Aluminium is a good conductor of heat, which makes it a poor insulator. However, aluminium windows provide excellent thermal efficiency thanks to the clever thermal breaks in the frame.
- Maintenance: Aluminium windows require more maintenance than UPVC windows. They may need to be painted or anodized to protect them from corrosion, which can be costly and time-consuming.
UPVC vs Aluminium Windows: Which is Best?
Choosing between UPVC and aluminium windows can be a tough decision. It depends on your budget, aesthetic preferences, and the specific requirements of your building. Here are some scenarios where each material is the best choice:
When to Choose UPVC Windows
UPVC windows are a fantastic choice for many situations. They are the best option when:
- You need to fit a large number of windows: UPVC is a cost-effective material, making it a great choice for large installations. When you have a lot of windows to fit, UPVC windows are a more economical option compared to aluminium windows.
- You live in a noisy area: UPVC windows have excellent noise reduction properties due to their non-conductive qualities. If you live in a noisy area, UPVC windows will provide a quieter and more peaceful environment.
- You live in a coastal area: Although powder-coated aluminium windows are rust-free, UPVC frames perform better in the harsh conditions of many coastal areas.
UPVC windows are a reliable and dependable material for both windows and doors. They are durable, energy-efficient, and low-maintenance, making them a great investment for any building.
When to Choose Aluminium Windows
Aluminium windows are a great option for many situations. They are the best choice when:
- Aesthetics matter: If you value the appearance of your installation and are willing to pay the extra cost, aluminium windows are always the best choice. They have a sleek, modern appearance that many people find attractive.
- You need room dividers: Aluminium materials for windows are an excellent option for internal room dividers where insulation is not a concern. They are strong and can support large glass panels without obstructing the view.
- You need slim frames: Aluminium frames are typically much thinner than UPVC frames, making them ideal for picture windows where the view is important.
Aluminium windows are ultra-strong and long-lasting. They are resistant to weather, corrosion, and rot, making them ideal for harsh climates and coastal areas. They also have a sleek, modern appearance that many people find attractive.
How Much More Expensive Are Aluminium Windows?
Aluminium windows are more expensive than UPVC windows, but the price difference depends on many factors. According to Checkatrade, an independent trade site, aluminium windows cost around £350 to £600, whereas UPVC windows cost £250 to £400. This means that aluminium windows are typically 30% to 40% more expensive than UPVC windows.
However, many things can influence this cost – such as glazing, frame finishes, and other special features, which come with added expense for both materials. Therefore, it’s essential to compare the prices of both options and consider your specific needs to make the best choice.
How Can I Keep Costs Down?
If you want to keep costs down, there are a few things you can do:
- Choose a stripped-down aluminium window installation without any extra features or customizations.
- Opt for UPVC windows instead of aluminium windows.
- Go for a basic UPVC installation and add extras to come out with a similar cost overall.
Conclusion
Choosing between UPVC and aluminium windows can be challenging, but understanding the pros and cons of each material can make the decision easier. Both materials are excellent options for windows and doors, with their unique advantages and disadvantages. UPVC is cost-effective, low-maintenance, and energy-efficient, while aluminium has a sleek, modern appearance and is durable and strong. Ultimately, the choice depends on your budget, aesthetic preferences, and specific requirements. At the end of the day, either option will provide you with high-quality, long-lasting windows that will add value to your building.
