Choosing new windows is a long-term decision that affects the look, comfort, and efficiency of your home. Two of the most popular options are uPVC and aluminium windows, but they offer quite different benefits.
Across Surrey, homeowners often weigh up these choices depending on the age, style, and condition of their property — from period homes in Godalming to more contemporary builds in Guildford.
Understanding the differences will help you make the right decision for your home and budget.
What Are uPVC Windows?
uPVC (unplasticised polyvinyl chloride) windows are one of the most commonly installed window types in the UK.
They are known for being cost-effective, low maintenance, and energy efficient. Once installed, they require very little upkeep and do not need painting or sealing like timber frames.
uPVC windows are often chosen for their practicality, especially in family homes and properties where affordability and efficiency are key priorities.
What Are Aluminium Windows?
Aluminium windows use strong, lightweight metal frames that allow for slimmer sightlines and a more modern appearance.
They are known for their durability and sleek design, making them popular in contemporary homes or renovations where a minimalist finish is preferred.
Because aluminium is so strong, it allows for larger panes of glass and thinner frames, which can increase natural light inside the home.
uPVC vs Aluminium: Key Differences
Both options perform well, but they suit different types of homes and priorities.
Appearance
uPVC windows tend to have a more traditional or neutral look, which works well across a wide range of properties. Aluminium windows offer a more modern, streamlined aesthetic.
In areas like Farncombe and Milford, where homes often include a mix of older and mid-century housing, uPVC remains a popular and versatile choice. In contrast, aluminium is often chosen in newer developments or renovated properties around Guildford where a contemporary finish is preferred.
Energy Efficiency
Both uPVC and aluminium windows can achieve strong energy efficiency ratings when properly installed.
uPVC naturally provides good insulation due to its material properties. Aluminium windows use thermal breaks to achieve similar performance, making them highly efficient despite the metal frame.
For many homeowners in Godalming and surrounding villages, energy performance is a key factor when replacing older single-glazed or ageing double-glazed units.
Durability
Aluminium is extremely strong and resistant to corrosion, meaning it can last for decades with minimal maintenance.
uPVC is also durable, but may show signs of ageing slightly sooner depending on exposure and quality.
Both are designed to withstand typical UK weather conditions, but aluminium often edges ahead in terms of long-term structural stability.
Maintenance
Both options are low maintenance compared to timber.
uPVC windows only require occasional cleaning with soapy water. Aluminium windows are similarly easy to maintain and do not require repainting or treatment.
Which Is Best for Your Home?
The right choice often depends on the style and age of your property.
In Godalming and Farncombe, where many homes feature traditional or semi-detached housing, uPVC windows are often chosen for their balance of efficiency, cost, and suitability for existing architectural styles.
In Guildford and more modern developments across Surrey, aluminium windows are increasingly popular due to their slim profiles and contemporary appearance.
Milford properties often sit somewhere in between, with homeowners choosing either option depending on whether they want a more traditional or modern finish.
Professional Installation Matters
Whichever option you choose, installation plays a major role in performance.
Poorly fitted windows can lead to draughts, condensation issues, and reduced efficiency. A professional installation ensures proper sealing, alignment, and long-term reliability.
At Milford Window Company, we install both uPVC and aluminium windows across Surrey, including Godalming, Farncombe, Guildford, and Milford.
