Deciding between PVCu and aluminium windows can be pivotal in shaping the comfort, appearance, and efficiency of your home. Each type of window frame carries its own unique set of attributes and drawbacks, speaking to diverse homeowner preferences and practical requirements. We take into account factors such as strength, style, and environmental responsiveness to help you decide whether PVCu or aluminium windows are better for your home.
What are PVCu windows?
PVCu stands for unplasticised polyvinyl chloride. It’s a type of plastic that is rigid and durable, making it perfect for window frames. Renowned for their excellent insulation properties, resistance to moisture and corrosion, and low maintenance requirements, PVCu windows have long been a popular choice for homeowners.
What are aluminium windows?
Aluminium is a lightweight metal known for its strength and durability. Used commonly in construction for its resistance to rust and corrosion, it is an incredibly popular alternative for window frames. Aluminium windows are sleek and strong, providing a modern aesthetic. Aluminium is also recyclable, adding to its appeal for environmentally conscious homeowners.
Durability
- PVCu windows are highly durable, resisting rotting, warping, and corrosion, with a lifespan of 20–25 years and minimal maintenance.
- Aluminium windows are equally durable, if not more so, than PVCu windows. They can last up to 45 years with proper care and are resistant to weathering and corrosion, even in harsh climates.
Energy Efficiency
- PVCu windows are highly energy-efficient, featuring multiple chambers within the frame. These chambers significantly reduce heat transfer, keeping homes warm in the winter and cool in the summer.
- Modern aluminium windows are equipped with thermal breaks within the frame to enhance energy efficiency. While they may not match the insulation properties of PVCu, high-quality aluminium windows still offer good energy efficiency.
Cost Considerations
- PVCu windows are generally more affordable initially, making them an attractive option for most budget-conscious homeowners.
- Aluminium windows are typically more expensive upfront and require more maintenance over time. However, their long lifespan can still make them a cost-effective choice in the long run. This increased maintenance, combined with their higher initial cost, can make aluminium windows more expensive in the long term. Despite the durability and longer lifespan of aluminium, it is not always such a cost-effective solution.
Maintenance Requirements
- PVCu windows are virtually maintenance-free, requiring no minting or sealing. Regular cleaning with soapy water is essential to keep the frames looking their best, but hardware and seals may need some attention.
- In contrast, aluminium windows need slightly more maintenance, including regular cleaning and occasional re-coating, to maintain their appearance.
Both options are far better than traditional wooden frames when it comes to maintenance.
Aesthetic Appeal
- PVCu windows offer a range of styles and finishes, including wood grain effects that imitate traditional wooden frames. There are a huge number of customisations and finish options available, making them perfect for almost any home.
- Aluminium windows are renowned for their slim profiles and modern aesthetics. They are available in a wide array of colours and finishes, making them ideal for achieving a sleek and minimalist design in modern homes.
Both can be fitted with a range of glazing options to suit your preferences or home’s aesthetic.
Environmental Impact
Both PVCu and aluminium can be recycled, but their environmental impacts vary significantly.
- The production of PVCu involves chemicals, and despite being recyclable, about 82% of PVCu waste still ends up in landfills, according to the WWF.
- In contrast, recycling aluminium is highly efficient, requiring only 5% of the energy needed for new production. This makes it a more sustainable choice in the long run.
Security Features
Both PVCu and aluminium windows offer strong security features.
- PVCu windows, when equipped with multi-point locking systems and toughened glass, provide a high level of security and robust resistance to forced entry.
- Aluminium windows, known for their inherent strength, can also be fitted with advanced locking mechanisms and security features, delivering excellent protection for your home due to their durable construction.
Weather Resistance
- PVCu windows are highly weather-resistant, effectively handling rain, wind, and sunlight without corroding or rotting, making them suitable for diverse climates.
- Similarly, aluminium windows provide excellent weather resistance, enduring extreme temperatures and harsh conditions without degrading, thanks to the inherent properties of the material.
Noise Insulation
- PVCu windows offer excellent noise insulation due to their multi-chambered design and tight seals, effectively reducing outside noise and enhancing home comfort.
- Aluminium windows, particularly with thermal breaks and double glazing, also provide good noise insulation, but PVCu windows may have a slight advantage in this regard.
