Aluminium windows are an ideal choice for your next project, offering fantastic benefits that will enhance any home or business. Our Sheerline windows allow us to create designs for all types of property and aesthetics giving you complete flexibility.
But you might be wondering how aluminium windows compare against uPVC windows. This guide will cover many benefits including price and security, helping you make an informed decision. Read on to learn more.
Price
Whilst aluminium windows are generally more expensive than uPVC, the benefits of choosing them often outweigh the initial cost. Aluminium is incredibly strong yet lightweight, allowing for slimmer frames and larger panes of glass that maximise natural light and provide a sleek, modern look. It is also highly durable, resistant to warping, rotting, or discolouration, meaning it can last decades with minimal maintenance. Aluminium is 100% recyclable, making it a more sustainable option, and with advanced thermal break technology, it now offers excellent energy efficiency to rival or exceed uPVC options.
Thermal Efficiency
uPVC is a strong insulator of heat, as the double glazing will keep heat inside. However, our aluminium windows offer incredible energy efficiency, as they come with multiple chambers to significantly improve the insulation. This could help save your clients money on costly energy bills.
We also offer triple glazing with impressively low U-values of just 1.0 W/m²K, achieved through Sheerline’s patented Thermlock® technology and full-depth Eurogroove design. These innovations ensure long-term warmth and comfort, making our windows among the most thermally efficient on the market. Combining cutting-edge engineering with outstanding performance, our products give you the confidence that you are choosing the best solution for your client’s build.
Security
When it comes to security, aluminium windows have a clear advantage over uPVC. Aluminium is naturally stronger and more rigid, which makes the frames far more resistant to forced entry or damage. This inherent durability is further enhanced with advanced features such as quality hardware and multi-point locking systems, which secure the window at several points around the frame for maximum protection.
With the option to upgrade to PAS24 accreditation, aluminium windows meet the highest security standards required for modern homes and new builds. This means they are independently tested to withstand common techniques used by intruders, giving homeowners added peace of mind. Compared to uPVC, aluminium not only offers superior strength and longevity but also ensures a higher level of security as standard.
Maintenance
When it comes to maintenance for aluminium and uPVC windows, both are easy to look after. Both should be regularly cleaned with a soft cloth and mild non-abrasive cleaning products, and clean any dirt or debris form the hinge, pivots or sliding tracks. At least once a year check the tightness and security of fixings and using a light 3 in one oil lubricate the moving parts of the handle (but not the lock), use a small amount at each locking and pivot point and wipe away any excess with tissue.
Aluminium windows vs uPVC windows – a summary
While uPVC windows remain a popular choice for their affordability, aluminium windows stand out as the superior long-term investment. Thanks to their inherent strength, aluminium frames are slimmer yet more durable, allowing for larger expanses of glass and a sleek, modern appearance. They also boast exceptional security with secure multi-point locking and the option to upgrade to PAS24 standards, offering greater protection than uPVC. In terms of performance, modern aluminium windows feature advanced thermal break technology, delivering excellent energy efficiency alongside outstanding durability that resists warping, discolouration, and wear over time. Fully recyclable and virtually maintenance-free, aluminium windows combine sustainability, longevity, and premium design, making them the clear choice for homeowners and developers seeking quality and performance.
